Three more orca deaths take census count down to 73 Southern Residents

Four orca deaths and two births over the past year brings the official population of southern resident killer whales to 73 — the lowest number since the annual census was launched in 1976.

This evening, the keeper of the census — Ken Balcomb of the Center for Whale Research — sadly announced the deaths of three orcas who have not been seen for several months.

In past years, Ken waited until he and his staff have several opportunities to search for any whales that appear to be missing. But this year the whales have stayed almost entirely away from their traditional hunting grounds in the San Juan Islands, where they once stayed for nearly the full summer.

In an unusual move this year, Ken relied on reliable observers from the Canadian Department of Fisheries and Oceans as well as other biologists along the west coast of Vancouver Island. The missing whales were not seen during multiple encounters with the Canadians, Ken told me.

The reason the whales have not spent any time in Puget Sound is fairly obvious, Ken said. Their primary prey, chinook salmon, have not been around either.

Canadians produce mariner’s guide to whales; can U.S. follow?

If knowledge is power, officials in British Columbia have taken a strong step to protect whales by producing a booklet that can help ship captains reduce the threats to marine mammals.

The “Mariner’s Guide to Whales, Dolphins and Porpoises of Western Canada” (PDF 39.3 mb) was compiled and published by the Coastal Ocean Research Institute, a branch of the Vancouver Aquarium. Financial support came from nearby ports.

The guide is just one step in resolving conflicts between ships and whales, but it seems like a worthwhile move. If people who control the ships are willing to put scientific information into action, they could avoid cumbersome regulations along with unintended consequences that sometimes arise from political battles.

“The purpose of this guide is to help mariners reduce their risk of striking and killing, or seriously injuring a cetacean (whale, dolphin or porpoise),” writes researcher Lance Barrett-Lennard in a preface to the guide. “It includes descriptions of frequently encountered whales and dolphins, locations along the coast where cetacean densities are highest, and simple measures they can take to greatly reduce their risk of striking a whale, dolphin or porpoise.

“I have yet to meet a mariner who doesn’t feel terrible if his or her ship hits a cetacean … so I know the motivation to reduce strikes is there,” Lance continued. “The key is knowing how to do it. To that end, I hope that bridge crews on vessels transiting through B.C. coastal waters will use the information in this guide to reduce the risk of hitting a whale on their watch.”

Will the Navy extend whale protections
to other regions?

UPDATE, Oct. 2, 2015
The Navy has released its final environmental impact statement on Northwest testing and training operations. The document does not consider an option for avoiding “biologically significant areas” when using sonar or explosives, as in the legal settlement for operations in California and Hawaii. It is yet to be seen whether National Marine Fisheries Service will add new restrictions when issuing permits for incidental “take” under the Marine Mammal Protection Act. Here is the news release (PDF 548 kb).
—–

A legal agreement approved this week to limit the Navy’s use of sonar and explosives in “biologically important areas” of Southern California and Hawaii represents a “sea change” in the Navy’s protection of marine mammals, says Michael Jasny of the Natural Resources Defense Council.

Encouraged by the cooperative effort to reach an out-of-court settlement with the Navy, Michael said the deal could have implications for future Navy activities in the Northwest and throughout the country.

The NRDC and seven other environmental groups filed suit over Navy plans to train with sonar and explosives in Southern California and Hawaii with no specific geographic limitations. The environmental groups argued that one good way to reduce injury and death to marine mammals is to avoid areas where large numbers of whales and dolphins congregate to feed, socialize and reproduce.

A federal judge ruled in favor of the environmental groups, saying “it makes no sense” for the Navy to insist that its training exercises require the use every square mile of ocean. The ruling drew the Navy into settlement negotiations.

“This settlement resulted from a constructive good-faith effort on all sides,” Michael Jasny told me by phone. “That, in itself, represents a real change in the way the Navy has interacted with the conservation community. It took litigation to create this window of opportunity to advance policy to be consistent with science.”

Michael said research by the Navy and other groups has shown how marine mammals are killed and injured by Navy sonar and explosives. As the science has evolved, so have the tools to reduce impacts — such as maps showing where marine mammals hang out, maps that can help the Navy reduce its harm to many species.

Michael said it has been shameful to watch the National Marine Fisheries Service — the agency charged with protecting marine mammals — stand by and issue permits that allow the Navy to do whatever it wants. Now, he added, the negotiations between the Navy and environmental groups provide a blueprint for how NMFS can better live up to its mission of protecting marine mammals.

“Frankly, after years of fighting about these issues, we are seeing folks on both sides very willing to find solutions,” Michael said. “Folks on the Navy side have generally been willing to come to the table. The Navy would not have entered into this agreement if it believed these measures prevented it from achieving their military readiness objective.”

For its part, the Navy tends to downplay the significance of this week’s settlement.

“After a federal court ruled in favor of plaintiffs’ claims, the Navy faced the real possibility that the court would stop critically important training and testing,” said Lt. Cmdr. Matt Knight, spokesman for the Pacific Fleet. “Instead, NMFS and the Navy negotiated in good faith with the plaintiffs over five months to reach this agreement.”

In a written statement, Knight said the Navy’s existing protective measures are “significant” and the agreement increases restrictions in select areas. Those restrictions will remain in place until the current permit expires on Dec. 24, 2018.

“It is essential that sailors have realistic training at sea that fully prepares them to prevail when and where necessary with equipment that has been thoroughly tested,” Knight said in the statement. “This settlement agreement preserves critically important testing and training.”

In an email, I asked the Navy spokesman how the agreement might translate into special protections in other areas, particularly the Northwest where we know that Navy ships cross paths with many different kinds of whales and dolphins. His answer was somewhat vague.

“The Navy continues to work with NMFS to develop necessary and appropriate measures to protect marine mammals,” he wrote back. “The Navy’s current protective measures afford significant protections to marine mammals. That said, the Navy will not prejudge what measures will be appropriate to address future proposed actions.”

The Navy is about to complete an environmental impact statement that outlines the effects of its testing and training operations in Puget Sound and along the Washington Coast. In comments on the draft EIS and proposed permit, environmental groups again called attention to the need to restrict operations in places where large numbers of marine mammals can be found. For example, one letter signed by 18 conservation groups addresses the operational details in the Northwest Training and Testing Range:

“Despite the vast geographic extent of the Northwest Training and Testing Study Area, the Navy and NMFS have neither proposed nor adequately considered mitigation to reduce activities in biologically important marine mammal habitat. Virtually all of the mitigation that the Navy and NMFS have proposed for acoustic impacts boils down to a small safety zone around the sonar vessel or impulsive source, maintained primarily with visual monitoring by onboard lookouts, with aid from non-dedicated aircraft (when in the vicinity) and passive monitoring (through vessels’ generic sonar systems).

“The NMFS mitigation scheme disregards the best available science on the ineffectiveness of visual monitoring to prevent impacts on marine mammals. Indeed, the species perhaps most vulnerable to sonar-related injuries, beaked whales, are among the most difficult to detect because of their small size and diving behavior. It has been estimated that in anything stronger than a light breeze, only one in fifty beaked whales surfacing in the direct track line of a ship would be sighted. As the distance approaches 1 kilometer, that number drops to zero. The agency’s reliance on visual observation as the mainstay of its mitigation plan is therefore profoundly insufficient and misplaced.”

Even before this week’s out-of-court settlement, environmental groups were urging the Navy and NMFS to delay completion of the EIS until they fairly evaluate new studies about the effects of sonar, explosives and sound on marine mammals. Measures to protect whales and other animals should include restrictions within biologically important areas, they say.

This week’s out-of-court settlement included limitations on the use of sonar and explosives in the BIAs of Southern California and Hawaii. For details, check out the signed order itself (PDF 1.5 mb) with associated maps, or read the summary in news releases by NRDC and Earthjustice. Not all BIAs that have been identified are getting special protection under the agreement.

Biologically important areas for whales, dolphins and porpoises include places used for reproduction, feeding and migration, along with limited areas occupied by small populations of residents. For a list of identified BIAs, go to NOAA’s Cetacean and Sound Mapping website. For additional details, see NOAA’s news release on the subject.

Michael Jasny said he is encouraged with the Navy’s acknowledgement that it can adequately conduct testing and training exercises while abiding by restrictions in specified geographic areas. He hopes the Navy uses the same logic to protect marine mammals on the East Coast, including Virginia where seismic exploration increases the risk; portions of the Gulf of Mexico; the Gulf of Alaska; the Mariana Islands; and, of course, the Pacific Northwest.

Zak Smith, an NRDC attorney involved with Northwest sonar issues, said the settlement in California and Hawaii should encourage the National Marine Fisheries Service to apply the same mitigation to testing and training to waters in Washington, Oregon, California and Alaska.

“I would hope when they come out with a final rule that the Fisheries Service would have engaged with the kind of management approach that we did in the settlement,” he said. “The Fisheries Service and the Navy should sit down and review biologically significant areas against the Navy’s training and testing needs.”

Clearly, if you read through the comments, environmental groups are dismayed about the Navy’s potential harm to marine mammals and its failure to address the problem:

“The sonar and munitions training contemplated in the Navy’s NWTT Draft Environmental Impact Statement is extensive and details extraordinary harm to the Pacific Northwest’s marine resources…. Even using the Navy and NMFS’s analysis, which substantially understates the potential effects, the activities would cause nearly 250,000 biologically significant impacts on marine mammals along the Washington, Oregon, Northern California, and Southern Alaska coasts each year – more than 1.2 million takes during the 5-year life of a Marine Mammal Protection Act incidental take permit.”

I’m not sure it is necessary for me to point out that without significant changes to the Navy’s current plans, we are likely to see another lawsuit over routine testing and training operations.

New reports of whale territory could shape protection strategy

Researchers have listed more than 100 “biologically important areas” for whales and dolphins living in U.S. waters, all reported in a special issue of the journal Aquatic Mammals (PDF 22.9 mb).

Journal

The BIAs may provide useful information, but they are not marine protected areas, and they have no direct regulatory effect, said Sofie Van Parijs, a researcher at NOAA’s Northeast Fisheries Science Center and guest editor of the special report.

“They represent the best available information about the times and areas in which species are likely to be engaged in biologically important activities,” Van Parijs said in a news release. “We encourage anyone planning an activity in the ocean to look at this information and take it into consideration to understand and reduce adverse impacts on marine species.”

Project managers can use information in the report for offshore energy development, military testing and training, shipping, fishing, tourism, and coastal construction. Underwater noise, generated by most human activities in or on the water, can affect large areas of whale territory.

Separate articles were written about seven regions of the country, with three of them in Alaskan waters. The lead author for the West Coast regional report (PDF 4.5 mb) is John Calambokidis of Cascadia Research Collective in Olympia.

The West Coast report identified 29 BIAs covering areas important for blue whales, gray whales, humpback whales and harbor porpoises in Washington, Oregon and California. BIAs for blue whales and humpback whales are “based on high concentration areas of feeding animals observed from small boat surveys, ship surveys and opportunistic sources,” the report says.

BIAs for gray whales focus on their migratory corridor from Mexico to Alaska, along with primary feeding areas for a small resident population known as the Pacific Coast Feeding Group, or PCFG. This group, believed to be genetically distinct from the migratory whales, spend most of their time between Northern California and Canada’s Vancouver Island.

The BIAs for gray whales in Washington are around the northwest tip of Washington, including Neah Bay; in Saratoga Passage east of Whidbey Island; and around Grays Harbor on the coast.

Map

The PCFG could be a key factor in determining whether the Makah Tribe of Neah Bay is granted a permit to hunt for gray whales in Washington state waters and limiting potential limits on any hunts approved. It was interesting that the BIA report came out at almost the same time as an environmental impact statement on the Makah whaling proposal.

The impact statement evaluates alternatives for whaling, including a tribal proposal to hunt up to five whales a year but no more than 24 whales in six years. Various alternatives include plans to limit hunting seasons to reduce the risk of killing a whale from the Pacific Coast Feeding Group and to cease hunting if a quota of these whales is reached.

“This is the first step in a public process of considering this request that could eventually lead to authorization for the tribe to hunt gray whales,” said Donna Darm, NOAA’s associate deputy regional administrator, in a press release. “This is the public’s opportunity to look at the alternatives we’ve developed, and let us know if we have fully and completely analyzed the impacts.”

For details on this issue, including the EIS and instructions for commenting on the document, check out NOAA’s website on the Makah Whale Hunt.

Returning to the study of biologically important areas, no BIAs were established for endangered fin whales, because of discrepancies between sightings and expected feeding areas and uncertainty about their population structure.

The BIA assessment did not cover minke whales, killer whales, beaked whales and sperm whales but the authors recommend that future work cover those animals as well as looking into special breeding areas for all the whales.

A future BIA for killer whales could have some connection to an ongoing analysis by NOAA, which recently announced that it needs more information about Southern Resident killer whales before expanding their critical habitat under the Endangered Species Act. See Water Ways from Feb. 24.

In the overall report, BIAs can be established if they have any of the following characteristics:

  1. Reproductive areas – Areas and times within which a particular species selectively mates, gives birth or is found with neonates or calves,
  2. Feeding areas – Areas and times within which aggregations of a particular species preferentially feed. These either may be persistent in space and time or associated with ephemeral features that are less predictable but are located within a larger area that can be delineated,
  3. Migratory corridors – Areas and times within which a substantial portion of a species is known to migrate; the corridor is spatially restricted.
  4. Small and resident population – Areas and times within which small and resident populations occupy a limited geographic extent.

New orca baby doing well, closely linked
to 43-year-old female

The young killer whale born into J pod three weeks ago still appears to be doing well, according to Dave Ellifrit of the Center for Whale Research, who observed the calf when her pod came through the San Juan Islands on Monday.

In his written notes, Dave said the calf, designated J-50, was staying close to J-16, a 43-year-old female named “Slick.” Meanwhile, Slick’s daughter, 16-year-old J-36 or Alki, remained some distance away.

Uncertainty has surrounded the question of whether J-16 is the mother or the grandmother of the new calf. If she’s the mother, it will be the first time that an orca over 40 has been known to give birth, at least among the three pods that frequent Puget Sound.

As Dave noted in his observations:

“While all the J16’s traveled together, J36 was consistently the farthest of the group from J50, so whatever doubts remained about J16 being the mother are about gone.”

Ken Balcomb, who founded the Center for Whale Research, was not with Dave during the encounter. Ken agrees that current evidence points to J-16 being the mom, but he is still not totally convinced.

“I’m staying open,” he told me. “J-16 is certainly the primary caregiver.”

There remains a little matter of the “rake marks” on the back of the baby orca — most likely caused when an adult whale used its teeth to pull the newborn from the birth canal. A 16-year-old female might need some help during delivery, Ken explained, and the grandmother was the likely one to assist. Such help probably would not be needed for an older mom, he said.

I thought that the proof of motherhood would come when we knew who was nursing the baby. While nobody has directly observed any nursing behavior over the past three weeks, the baby is fattening up and staying near enough to J-16 to allow such things to happen.

But Ken says it is possible that J-16 could be lactating — even if she is the grandmother. It’s happened in older pilot whales, he noted.

“It is not beyond the realm of possibility that a grandmother could play the nurse-maid role,” he said.

There will be no certainty about the lineage, he said, until genetic testing is performed, and that could take years — assuming the calf survives. Such tests could come as the result of fecal sampling or a skin biopsy performed by approved researchers following the whales, he said.

Meanwhile, since the calf was born, J pod has been moving around the inland waterways and well up into the Strait of Georgia in Canada, as revealed by a satellite transmitter carried by J-27, a 24-year-old named Blackberry.

Jan. 17-21. To save battery power, the satellite transmitter began sending signals every other day. Still, it was clear that the J pod whales traveled south from Texada Island and passed through the San Juan Islands by Monday afternoon of this week. From there, they made a straight run to the ocean, then turned around on Tuesday and headed back into the Strait of Juan de Fuca by yesterday afternoon. This time, they were accompanied by K pod, according to observers. Map courtesy of NOAA

A couple times in the past two weeks, the whales went through the Strait of Juan de Fuca and into the Pacific Ocean. But each time they quickly turned around and came back,

Last night, Mark Malleson of Prince of Whales, a whale-watching company, observed J pod along with K pod spread out in the Strait of Juan de Fuca near Sheringham Point near the south tip of Vancouver Island, according to his report posted on Orca Network’s Facebook page.

So far today, I have not heard any more reports, and the next satellite data won’t be available until later.

‘War of the Whales’ :
My take on the book by Joshua Horwitz

In the book “War of the Whales,” author Joshua Horwitz reveals, in exquisite detail, how Ken Balcomb played a central role in showing how Navy sonar was killing and injuring whales around the world.

Book

Ken, who we know as the dean of orca research in Puget Sound, has not been alone, of course, in the quest to get the Navy to better protect marine mammals. Horwitz introduces us to a variety of people, each with his or her own interest in saving the whales.

Frankly, I was surprised at how much I learned from the book, given that I have been covering these same issues as a reporter for many years. What really gained my admiration for Horwitz was how he was able to weave scientific and historical aspects of the story into a gripping tale that reads like a detective thriller.

I consider this book to be several stories woven into one. First, there are the personal biographies of two key players in this conflict with the Navy. The lives of Ken Balcomb, of the Center for Whale Research, and Joel Reynolds, of the Natural Resources Defense Council, became intertwined with each other after the NRDC sued the Navy over its use of sonar around whales.

Next, we are given the history of the Navy’s sonar technology, developed to track stealthy submarines. We meet many of the Navy officials involved, including some who became emotionally involved with marine mammals, flipping to the other side, as Horwitz describes it.

The Navy has long controlled much of the research involving marine mammals — the original models for sonar. At times, whales and dolphins were even trained as military combatants, with mixed success.

Last, but not least, we are shown the legal arguments related to environmental law versus the need for national security. As a result, we see how the Navy has become more open today about the risks to whales from its testing and training procedures.

Horwitz paints intimate portraits of many of the characters, especially Balcomb, the biologist, and Reynolds, the lawyer. He sees the pair coming together from different backgrounds and uniting in their effort to protect the whales against the Navy’s single-minded approach to national security.

“Ken was such an extraordinary character,” Horwitz told me in a telephone interview. “He was a reluctant activist. Activism wasn’t Ken’s thing.”

The story begins in the Bahamas, where Balcomb was doing research when a mass stranding of beaked whales took place, practically at his doorstep. Navy sonar had been suspected of killing whales in other areas of the world, but Balcomb was able to secure fresh tissues — essential evidence to understand how their injuries were caused by sound waves. Balcomb also observed that the Navy was conducting exercises in the Bahamas at the same time, and he made the connection to the dead whales.

From there, other researchers and policy officials became involved, but Balcomb kept pushing to keep the incident from being swept under the rug.

“Ken’s investment was immediate,” Horwitz explained. “One night the Navy just plowed through and decimated this population of whales.”

We learn from the book about Ken’s serendipitous life. As a young biologist, he collected whale lungs for research by going to a commercial whaling station still operating in California. He later signed onto a research crew as a dishwasher, but his skills with a shotgun earned him the lead job of tagging whales.

Balcomb joined the Navy during the Vietnam War and became a pilot. A series of circumstances led him into Fleet Sonar School and the Navy’s highly secretive Sound Surveillance System, or SOSUS. At the same time, his compatriots in graduate school became some of the top marine mammal experts for the Navy and the National Marine Fisheries Service. His later interactions with these folks revealed something about their past and present positions in life.

Horwitz ties all these pieces of the story together in a compelling narrative that kept offering me new and surprising tidbits of information. It took the author seven years to complete the book.

“He kept asking over and over the same questions,” said Ken, somewhat amused when I asked him about it. “I didn’t know if he had confused notes or what.”

Horwitz was seeking an extraordinary level of precision and accuracy, so that his telling of this true and controversial story could not be assailed.

Balcomb said he could find no errors, except for the conscious decision by Horowitz and his editors to describe two overflights by Balcomb in the Bahamas as a single event.

Most surprising of all was the account from Navy officials, whose story about underwater warfare has rarely been told, except perhaps in novels by Tom Clancy and others. Horwitz said active-duty military officials were no help to him, but he got to know retired Admiral Dick Pittenger, who opened doors to other retired officers.

“He (Pittenger) was a total career Navy guy, but he was skeptical about the way the Navy was handling some of these matters,” Horwitz said, noting that the admiral spent days helping him understand anti-submarine warfare.

Pittenger wanted the story told right, and he must have been satisfied with the result, since he offered this comment in promotional materials for the book:

“‘War of the Whales’ is an important book about a major post-Cold War problem: the often conflicting goals of national security and environmental protection. The author presents this very complex and multidimensional story with great clarity.

“I’m certain that no one who has been involved with this issue will agree with everything in this book (I don’t). But the topic is, by its nature, so emotionally charged and controversial that I doubt anyone can read it without a strong personal response. The importance of this book is that it tells the ‘inside’ story to the wide reading public in a compelling way.”

In my mind, Horwitz did a remarkable job of capturing the relevant facts for this complicated story. He then seamlessly joined the pieces together into a coherent and dramatic story — one especially important to those of us living in an area where the Navy maintains a strong presence among an abundance of marine life.

Check back to “Watching Our Water Ways” tomorrow, when I will describe more of Josh Horowitz’s personal views about his book and what he learned along the way.

It’s a girl! Orca gender identified; her mother remains a mystery

Thanks to a baby photo from Jane Cogan, the newest killer whale in J pod has been identified as a girl, according to Ken Balcomb of the Center for Whale Research.

We still don’t know whether the mother is 42-year-old J-16, known as Slick, or Slick’s 16-year-old daughter J-36, known as Alki. At moment, the family group, which consists of J-16, her three offspring plus the new calf, are sticking close together.

“It may take a little time for us to sort it out,” Ken told me, but the mother should become apparent within a few weeks, if not sooner, because the calf must be getting milk from the mom. From all indications, the little one is doing fine.

Initially, the calf was thought to be the offspring of J-16, because J-36 was some distance away. But now it seems just as likely that J-16 was babysitting while J-36 got some rest, Ken told me.

Yesterday, Jane and Tom Cogan of San Juan Island took an overnight trip up north into British Columbia, where J pod has been swimming near Texada Island since the beginning of the new year. Jane sent back a good photograph of the baby’s underneath side. According to Ken, it is not unusual for mothers to roll their babies near the surface of the water.

Female killer whales have a more rounded pattern in the genital area, while males have a more elongated pattern of coloration. A good photo is all it takes to tell a boy from a girl. For comparison, see Questions & Answers at Center for Whale Research website.

I talked to Tom briefly this afternoon. He told me that J-50 was acting playful at times, like young whales will do, with some tail slapping and porpoising.

“I would say it looked healthy,” he said. “It was following J-16 a lot of the time, but all of the family was in the area, and they would group up at times.

“We’ll show Ken our pictures and debrief him when we get back,” he added.

Because J-27, a male in J pod, has been carrying a satellite transmitter since Dec. 28, experts have a pretty good idea about their location, as the orcas move about. Check out the maps on NOAA’s website, “2015 Southern Resident Killer Whale Satellite Tagging.”

As of this afternoon, J pod, including the J-16 clan, was near Nanaimo, B.C., and headed south toward the Washington border, according to Tom Cogan, who was in the vicinity.

International court rules against Japanese whaling

Japanese whalers who hunt whales in the Antarctic can no longer justify their actions as “scientific research” and must stop their annual whale roundup, according to a ruling by the International Court of Justice.

The court ruled today that Japan’s so-called “research” does not meet ordinary scientific standards. The court ordered Japan to stop killing whales under the guise of its research program, called JARPA II. As stated in a 73-page finding (PDF 649 kb) supported by 12 of the 16 judges:

“Taken as a whole, the Court considers that JARPA II involves activities that can broadly be characterized as scientific research, but that the evidence does not establish that the programme’s design and implementation are reasonable in relation to achieving its stated objectives.

“The Court concludes that the special permits granted by Japan for the killing, taking and treating of whales in connection with JARPA II are not ‘for purposes of scientific research’ pursuant to Article VIII, paragraph 1, of the Convention (the International Convention for the Regulation of Whaling).”

In the legal action brought before the United Nations court by Australia, the judges carefully scrutinized the JARPA II methods and procedures. They found that the sampling procedure and lethal take of minke, fin and humpback whales falls short of legitimate scientific study in many regards:

“The fact that the actual take of fin and humpback whales is largely, if not entirely, a function of political and logistical considerations, further weakens the purported relationship between JARPA II’s research objectives and the specific sample size targets for each species — in particular, the decision to engage in the lethal sampling of minke whales on a relatively large scale.”

A news release (PDF 174 kb) issued by the court does a fair job of summarizing the findings:

“Examining Japan’s decisions regarding the use of lethal methods, the court finds no evidence of any studies of the feasibility of or the practicability of non-lethal methods, either in setting the JARPA II sample sizes or in later years in which the programme has maintained the same sample size targets. The court also finds no evidence that Japan examined whether it would be feasible to combine a smaller lethal take and an increase in non-lethal sampling as a means to achieve JARPA II’s research objectives.”

After the ruling, Koji Tsuruoka, Japan’s representative at the court, addressed reporters at the Peace Palace in The Hague. According to a report by Australian Associated Press, Tsuruoka stated:

“Japan regrets and is deeply disappointed that JARPA II … has been ruled by the court as not falling within the provisions of Article 8. However, as a state that respects the rule of law, the order of international law and as a responsible member of the global community, Japan will abide by the decision of the court.”

He said Japanese officials would need to digest the judgment before considering a future course of action. He refused to discuss whether a new research program could be crafted to allow whaling to resume.

Australian officials were careful not to gloat over the victory as they emphasized the need to maintain favorable relations with Japan. Bill Campbell, Australia’s general counsel in the case, was quoted by the AAP:

“The decision of the court today, important as it is, has given us the opportunity to draw a line under the legal dispute and move on.”

The ruling was welcomed by environmental groups, including Sea Shepherd Conservation Society, which has sent ships to the Antarctic to directly confront the whaling ships and interfere with their whaling activities, as seen on the television show “Whale Wars.” Capt. Alex Cornelissen of Sea Shepherd Global had this to say in a news release:

“With today’s ruling, the ICJ has taken a fair and just stance on the right side of history by protecting the whales of the Southern Ocean Whale Sanctuary and the vital marine ecosystem of Antarctica, a decision that impacts the international community and future generations. Though Japan’s unrelenting harpoons have continued to drive many species of whales toward extinction, Sea Shepherd is hopeful that in the wake of the ICJ’s ruling, it is whaling that will be driven into the pages of the history books.”

Oceanic killer whales being tracked near Hawaii

For the first time, researchers are tracking by satellite a group of “tropical oceanic” killer whales, a type rarely seen and almost a complete mystery to scientists.

Researchers from Olympia-based Cascadia Research were in Hawaii, on the final day of a 15-day research cruise to study marine mammals, when they encountered four killer whales offshore from Kona. They were the type of orca known to roam the open ocean, but rarely seen by human observers.

In fact, in 14 years of research work in Hawaii, Cascadia’s Robin Baird said he has encountered these tropical killer whales only three times twice before. Others have seen them on occasion, but sightings are few and far between.

This time, on Nov. 1, Baird’s crew was able to obtain samples of skin for genetic work, which will help determine how closely these whales are related to other orcas throughout the world. The crew also attached satellite transmitters to three of the four whales.

Two of the transmitters are still transmitting nearly two weeks later, and Baird hopes at least one will continue working for several more weeks. In warmer waters, the barbed “tags” tend to fall off sooner than in Northwest waters, Robin told me. As you can see from the map, the whales first moved west, then north, then west again. As of the latest plot this morning, they were west and slightly south of Kauai.

By coincidence, two underwater photographers captured video and still photos of these killer whales around the time the Cascadia crew was in the area off Kona. Deron Verbeck and Julie Steelman told KHON-TV that the experience was the pinnacle of their career. (See video below.)

Although Nov. 1 was the last official day of the Cascadia cruise, researcher Russ Andrews and several others went back out on Saturday to find the four killer whales. They spotted three other orcas with them. During the outing, they observed predation on a thresher shark, something that photographer Verbeck also reported.

These tropical oceanic killer whales are smaller than the familiar resident and transient killer whales of the Northwest, Robin Baird explained. Instead of a white “saddle patch” near the dorsal fin, these animals have a gray, almost black patch that is difficult to see.

These are not the “offshore” killer whales that roam miles of the West Coast, but generally stay on or near the continental shelf, Robin told me. Still, it will be interesting to see if the tropical oceanic orcas are closer genetically to the offshores, which are known to eat sharks.

We do know the Southern Resident orcas, which frequent Puget Sound, specialize in eating salmon, particularly chinook. But Robin says whales feeding in the open ocean probably don’t encounter enough of any one prey type to be so specialized. Considered generalists, they have been known to eat squid, sharks, dolphins and occasionally larger whales.

Robin says little is known about how they group together, because the number of photo identifications is small. Generally, the groups are five or less. The groups are likely to be families, including a female and all her offspring. This is the same type of matriarchal society found in other orca groups, although in some orca societies — such Southern Residents — one matriline often joins with others.

Robin says just about everything learned about their travels is new, “from short-term movement rates, habitat use, and — if the tags stay on for a while — how often they may visit island-habitats (and) whether they cross international boundaries.”

In addition to Robin Baird and Russ Andrews, the research crew on the trip included Daniel Webster, Annie Douglas and Annie Gorgone, all from Cascadia; Amy Van Cise from Scripps Institution of Oceanography and several volunteers.

Even before the killer whale encounter, the cruise was considered successful, Robin said. Twelve species of marine mammals were encountered, and satellite tags were deployed on six species, now being tracked. More than 40,000 photographs were taken, some of which are shown on Cascadia’s Facebook page or the project page on Cascadia’s website.

Dolphin rescue touches many hearts

If you haven’t seen it, I think you’ll be impressed with this video, which shows a bottlenose dolphin apparently asking for help from some scuba divers, who noticed the animal tangled in fishing line with a hook imbedded in its fin.

Martina Wing of Ocean Wings Hawaii captured the action, which really begins at 3:30 into the eight-minute video, though the early part sets the scene with some beautiful shots of manta rays. The encounter took place Jan. 11 off the west coast of the Big Island.

Reporter Philip Caulfield of the New York Daily News quoted Keller Laros, the diver who came to the rescue, as saying the dolphin was responsive to his gesture and deliberately moved in close to be helped:

“I noticed he had a fishing wire wrapped around his left fin. I reached out with my left hand … and gestured with my index finger ‘Come here.’ And he swam right up to me. The fact that he seemed to recognize my gesture, that blew me away.”

Laros was able to cut away the line and remove the hook, and the dolphin swam away.

The video has been viewed nearly 2 million times, with more than 2,000 comments posted to the site. I found some observations to be thought-provoking:

DavidKevin: I am overwhelmed.

I have been certain for over 35 years that we shared the planet with another sentient species, the dolphins, and this is just more evidence of it. We don’t have to go off-planet to find an alien species with whom to communicate, we just have to look offshore.

If we cannot learn to communicate with our distant mammalian relatives, we’ll never be able to communicate with true extra-terrestrials, should we ever meet them.

Marvelicious75: We use the word ‘sentient’ in a dialectic manner, but it is quite obviously not accurate. It is arrogance that makes us consider ourselves separate from ‘animals’ like the dolphin. This story isn’t truly surprising in light of the countless stories of dolphins rescuing humans. The only limiting factor is our surprising lack of empathy….

Hobbitfrdo: Sad day for the world if we stopped loving all creatures. Respect to you all.

Russell Laros: The diver cutting the line off in the video is my father. He was really happy to be able to make this connection to the animal and was pretty impressed by it’s intelligence. Apparently this dolphin has been in contact with humans before, though. It has been seen and interacted with workers at a local open ocean fish farm nearby. Still really amazing though….

Misa Eniaki Amane: This dolphin is smarter than all of us…..went up for air and back down to continue with the rescue.

supertekkel1: There are numerous_ ancient stories of dolphins rescuing sailors who went overboard. Whether they are true or not, it’s nice to see that we are finally able to do something to return the favor.

1Irisangel: What a blessing to have captured these moments on film. No words needed, only love and compassion for a fellow traveler on planet Earth. Wonderful capture Martina!

OonaCanute: Now to get rid of all the fishing nets and lines and hooks that kill thousands of dolphins like this beauty every year.

Alex Bruce: The trust the dolphin had in the humans in his time of need is humbling to me. Dolphins are very intelligent creatures and know when to allow man to handle and help them. The men that helped the dolphin have to have felt some sense of pride derived from their kindness and humane actions. I know I did when many years ago I helped rescue a pelican that had a 3-barb hook anchored in its wing and a weight that was attached to the fishing line. He said. “Thank you” in his way and took off in flight 🙂

bcmom5: Awesome. It swam around until it found the right person to help it. That person and all who had a hand in it were blessed with Dolphin Medicine which teaches us to get out and breathe, explore, play. Breathe new life into your life. Awesome. 🙂 Thank you for helping and for sharing.

userbc44: What a touching and pure video! I love the part at 4:33 when the diver goes to take off his lights and puts them on the sea floor, the dolphin swims right in front of him as to say, “Theres more! don’t go, here I am!”

POMPCATZ: Wonderful to watch this intelligent creature seek your help and let you finish the job after going up for air. This is just more proof these beautiful. intelligent life forms should not be slaughtered for ignorant tradition and profit.

KillerinExile: Dolphins seem almost sapient. If they’re smart enough to ask for help maybe we shouldn’t be eating and abusing them like we do.

starsbydaylight: … I am sure the majority of people are naturally happy to help distressed animals that keep their calm, sometimes being out of fear unreasonable while being rescued. Once I witnessed a toddler busy carefully rescue a butterfly drowning in a puddle of water. The intelligence of the dolphin and the kind manner of the diver made me cry. In fact the dolphin saved its own life….

flowerseva: This is the ‘Real News’ happening on Planet Earth! Imagine if the 6 o’clock nightly news was filled with these images and emotions – What kind of world would we then be creating??
