K pod makes rare spring visit to South Sound

Monday, April 14th, 2014

K pod, one of the three pods of orcas that frequent Puget Sound, came south through the San Juan Islands yesterday and were spotted in South Puget Sound late this afternoon.

It’s quite unusual to see K pod coming into Puget Sound this early in the year, noted killer whale researcher Brad Hanson of the Northwest Fisheries Science Center.

K pod contains 19 orcas and is often seen with other pods, but not this time. If history is any indication, they will soon be heading back out to the ocean. They are more likely to begin hanging out in the San Juan Islands in late May or early June.

Susan Berta of Orca Network told me that whale researcher Ken Balcomb had been out with the whales Sunday and was able to account for all the animals (no deaths), but there were no new babies either.

Brad said his crew collected two fecal samples, but they may not be representative of ocean feeding, since the whales have been around for more than a day. Research has been focusing on what Southern Resident orcas eat when they are in the ocean.

The whales may have been spotted first this morning by a crew on one of the Seattle ferries. The report to Orca Network was a single killer whale a mile north of Alki Point, about mid-channel, at 7:30 a.m.

The K pod reports came amidst other reports of transient killer whales heading north from Point No Point about 9:30 a.m., passing Whidbey Island an hour later and off Everett in the early afternoon, according to reports on Orca Network. Another group of transients was reported on the other side of Whidbey in Admiralty Inlet and later seen heading west in the Strait of Juan de Fuca.

Because of the multiple transient reports, Brad said he was caught by surprise this morning when he went out and found all of K pod swimming south in Colvos Passage off South Kitsap.

Normally, resident orcas first pass Vashon Island on the east side and come north through Colvos Passage.

“We kept getting all these weird reports,” said Susan, who was kept busy posting updates to Orca Network’s Facebook page. “We heard about one lone orca off Alki, then another group, and I said, ‘I wonder if that is K pod all strung out down there.’ We were not expecting that.”

Susan said it is rare, but not unprecedented, for residents to come into Puget Sound in early spring. In March 2006, K and L pods arrived together and went all the way south to Olympia.


Water quality is defined by its effect on sea life

Friday, April 11th, 2014

We just completed another group of stories in the ongoing series we’re calling “Taking the Pulse of Puget Sound.” This latest story package is about marine water quality and marine sediments. (The stories themselves require a subscription.)

For all my years of environmental reporting, I have to say that I’ve never really understood the meaning of water quality. Keeping the water free of chemicals and fecal bacteria is one thing. Safe levels of oxygen, temperature, acidity and suspended sediment are other important factors.

But in the real world, you never find ideal conditions. You take what you get: physical conditions dictated by weather, climate and bathymetry; a strange brew of toxic chemicals; and a mix of nutrients and organic material, all drifting through complex cycles of life and death.

Water quality means nothing without the context of living things. More than 1,000 species of tiny organisms live in or on the mud at the bottom of Puget Sound. In many areas, sensitive species have disappeared. We are left with those that can tolerate harsher conditions. Why are they dying off? What can be done about it?

Some plankton species are becoming more dominant, and the effects on the food web are unknown. When water quality is poor, Jellyfish are displacing forage fish, disrupting the food supply for larger fish.

We know that toxic chemicals are spilling into Puget Sound in stormwater and getting into the food web, first touching the tiniest organisms and eventually causing havoc for fish, marine mammals and humans. Compounds that mimic hormones are affecting growth, reproduction and survival for a myriad of species. Because of biomagnification, some chemicals are having serious effects at concentrations that could not be measured until recently.

Puget Sound can’t cleanse itself by flushing its chemicals and waste out to sea, as most bays do. Puget Sound is long and narrow and deep, and the exchange of water takes a long time. Most of the bad stuff floating in the water just sloshes back and forth with the daily tides.

We can’t forget that some of the good stuff floating around are microscopic plants that feed the food web, along with a variety of larvae that will grow into fish, shellfish and many other creatures. But many of these planktonic life forms are vulnerable to chemicals, which can reduce their ability to survive against predators, tipping the balance in unknown ways.

Understanding water quality is not so much about measuring what is in the water as understanding the effects on living things. Which species are missing from a given area of Puget Sound, and what killed them off?

Biological monitoring has been around for a long time, but we may be entering a new phase of exploration in which we begin to connect the dots between what takes place on the land, how chemicals and nutrients get into the water, and what that means for every creature struggling to survive.

We have some brilliant people working on this problem in the Puget Sound region. I would like to thank everyone who has helped me gain a better understanding of these issues, as I attempt to explain these complexities in my stories.

International court rules against Japanese whaling

Monday, March 31st, 2014

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.”


Tidal power supply coming to Puget Sound

Friday, March 21st, 2014

A multi-million-dollar tidal energy project in Admiralty Inlet, north of the Kitsap Peninsula, has been approved by the Federal Energy Regulatory Commission.

The Snohomish County Public Utility District, which was granted a license for the double-tidal-turbine pilot project, says it will be the first “grid-connected array of large-scale tidal energy turbines in the world.” The twin turbines are designed to produce 600 kilowatts of electricity, enough to power several hundred homes.

“Anyone who has spent time on the waters of Puget Sound understands the power inherent in the tides,” PUD General Manager Steve Klein said in a news release. “In granting this license, the FERC acknowledges the vigilant efforts of the PUD and its partners to test the viability of a new reliable source of clean energy while at the same time ensuring the protection of the environment and existing uses.”

The federal commission acknowledged concerns for fish and wildlife brought forth by area tribes, whale-watch operators and environmental groups. But the pilot project has precautionary measures built in, according to the commission’s order (PDF 503 kb) issued yesterday:

“For these new technologies, where the environmental effects are not well understood, the risks of adverse environmental impacts can be minimized through monitoring and safeguard plans that ensure the protection of the public and the environment.

“The goal of the pilot project approach is to allow developers to test new hydrokinetic technologies, determine appropriate sites for these technologies, and study a technology’s environmental and other effects without compromising the commission’s oversight of a project or limiting agency and stakeholder input…

“A pilot project should be: (1) small; (2) short term; (3) located in non-sensitive areas based on the commission’s review of the record; (4) removable and able to be shut down on short notice; (5) removed, with the site restored, before the end of the license term (unless a new license is granted); and (6) initiated by a draft application in a form sufficient to support environmental analysis.”

Among tribes that fish in the area, the Suquamish Tribe raised concerns about the likelihood of underwater turbines violating tribal treaty rights to fish. The turbines have the potential for killing or injuring fish, according to the tribes, and they could become a point of entanglement for fishing nets and anchor lines.

“Though we respect the tribes’ perspective and concerns, we disagree that licensing this project will adversely affect their treaty rights,” the commission stated in its order. The license contains no restrictions on fishing, and it requires measures to protect the fish.

Suquamish Tribal Chairman Leonard Forsman said tribal officials have not had time to review the license conditions in detail but will do so over the coming days. He said he would consult with legal and technical advisers before laying out possible actions for consideration by the tribal council.

Michael Harris, executive director of the Pacific Whale Watch Association and a board member for Orca Conservancy, said he was disappointed that more people have not recognized the problems that can be created by these turbines — especially in Admiralty Inlet, a primary route for killer whales and many other species.

The turbines will create unusually loud and potentially painful underwater noise, Harris said. This installation is being developed at a time when researchers are coming to understand that noise can disrupt the behavior of killer whales and other marine mammals.

The turbines themselves have open blades that can injure any curious animal getting too close, he noted. And if the turbines become a serious threat, someone must swim down and mechanically stop the blades from turning, something that could take four days.

“I’m not against green energy,” Harris said when I talked to him this morning. “But let’s not put blinders on. I would like to see these turbines located in another spot. Why not Deception Pass?”

Harris said it is critical for people to pay close attention to the pilot project if it goes forward. Everyone should be prepared to stop the experiment if it proves costly to sea life.

The order by the Federal Energy Regulatory Commission maintains that conditions of approval will protect killer whales and other marine mammals:

“The Near Turbine Monitoring and Mitigation Plan requires detection of fish and should provide observation of nearby killer whales. Those observations combined with the hydrophone monitoring required under the Marine Mammal Protection and Mitigation Plan will allow detection and observation of killer whales if they come near the turbines.

“The adaptive management provisions of the Marine Mammal Protection and Mitigation Plan will also allow adjustments to project operation if potential harm to killer whales is detected or, in the very unlikely event, a whale is injured….

“This license also contains noise-related requirements that will ensure the project does not have detrimental effects on killer whale behavior. The Acoustic Monitoring and Mitigation Plan of this license requires that if the sound level from turbine operation exceeds 120 dB at a distance greater than 750 meters from the turbine … the licensee shall engage the turbine brake until modifications to turbine operations or configuration can be made to reduce the sound level.”

According to several Internet sources, 120 dB is what someone might hear standing near a chainsaw or jack hammer. That level is considered close to the human threshold for pain.

In the Admiralty Inlet area, at least 13 local species are listed as threatened or endangered under the Endangered Species Act.

  • One plant: golden paintbrush, threatened
  • One bird: marbled murrelet, threatened
  • Two marine mammals: Southern Resident killer whales, endangered, and North Pacific humpback whale, endangered
  • Nine fish: Puget Sound Chinook salmon, threatened; Hood Canal summer chum, threatened; Puget Sound steelhead, threatened; bull trout, threatened; green sturgeon, threatened; bocaccio rockfish, endangered; canary rockfish, threatened; yelloweye rockfish, threatened; and Pacific eulachon, threatened.

U.S. Fish and Wildlife Service and National Marine Fisheries Service have concluded that none of the species would be in jeopardy of extinction because of the pilot project.

Experts have concluded that marine mammals, including killer whales, could be subjected to Level B harassment (behavioral shifts) as a result of noise from the turbines. That would be in violation of the Marine Mammal Protection Act without incidental take authorization. That means the Snohomish PUD must undergo consultations with the National Marine Fisheries Service and possibly change its plans before moving forward.

The PUD chose Admiralty Inlet for its swift currents, easy access and rocky seabed with little sediment or vegetation. A cable-control building for connecting to the power grid will be located on Whidbey Island near Fort Casey State Park. The turbines will be located in about 150 feet of water about a half-mile from shore.

The turbines are manufactured by OpenHydro of Dublin, Ireland. Each turbine measures about 18 feet in diameter, with a 414-ton total weight.

According to the PUD, these turbines have been used in ecologically sensitive areas in other parts of the world. One location is Scotland’s Orkney Islands, which features a diverse and productive ecosystem that is home to numerous species of fish, dolphins, seals, porpoises, whales and migrating turtles.

The pilot project has been supported with about $13 million in grants from the U.S. Department of Energy and Bonneville Power Administration along with federal appropriations.

Partners in various aspects of the project include the University of Washington, Pacific Northwest National Laboratory, Sound & Sea Technology and the National Renewable Energy Laboratory.


Washington now has an official state oyster

Monday, March 10th, 2014

Washington state now has an official state oyster, thanks to the lobbying efforts of 14-year-old Claire Thompson, who raised the prominence of the Olympia oyster as part as a school project. That’s assuming, of course, that the governor signs the bill.

I talked about Claire’s effort, along with Olympia oyster restoration projects, in a previous Water Ways post on Feb. 14.

The bill designating Ostrea lurida as the state oyster first passed the Senate Feb. 13 on a 47-1 vote. It was approved March 5 in the House, 94-4, after an amendment expanded the language of the bill to this:

“This native oyster species plays an important role in the history and culture that surrounds shellfish in Washington state and along the west coast of the United States. Some of the common and historic names used for this species are Native, Western, Shoalwater, and Olympia.”

The Senate then agreed to the amendment and passed the bill into law today, again on a 47-1 vote. Michael Baumgartner, a Republican from Spokane, was the only dissenting voice in the Senate.

Opponents in the House were Reps. Richard DeBolt, Chehalis; Brad Klippert, Kennewick; Jason Overstreet, Lynden; and Rep. Elizabeth Scott, Monroe. All are Republicans.

When Claire testified on the Senate bill in the House Government Operations and Elections Committee, she looked toward the future. When she testified on the earlier House version, she was looking to the past. You can hear her testimony in the viewer on this page, or at 56:40 on TVW.

Here’s what she said, in part, to the House committee:

“The last time I came to testify I talked about the history of this oyster. This time I would like to talk to you about what I hope is the future of this oyster…

“I am only 14 and most of my life still lies ahead. To make my future and the futures of all the kids who live around Puget Sound better, I would like you to not only pass this bill but get as many of these and other bivalves seeded and into the Puget Sound as quickly as possible. This is because these oysters filter the water and can help regulate harmful algal blooms, including the red tide. By keeping algae down, they increase the overall oxygen content for fish and crustaceans and all the other animals.

“In the large numbers that Puget Sound needs, these oysters can link together to build coral-reef-like structures that provide an ecosystem habitat of room and hiding for young sea animals and all the kelps and sea plants that we are losing… Oyster beds this thick keep sediments anchored and the entire Puget Sound in balance.”


Amusing Monday: Puzzling in the underwater world

Monday, March 10th, 2014

It’s been awhile since I brought you some puzzles, so I thought I’d mention a couple good jigsaw puzzle sites and offer a few interactive animations.

Yellow tan and clown fish puzzle. (Click to solve.)

Yellow tang and clown fish puzzle. (Click to solve.)

TheJigsawPuzzles.com site contains nearly 300 jigsaw puzzles of underwater scenes, including the one on this page. In addition, there are at least two dozen other categories to choose from.

You pick a scene and watch it crumble into 100 or more pieces. Online jigsaws often have special features, such as a quick sort of the edges. If you want a little more control, such as the ability to use your own picture in forming the puzzle, check out Jigsaw Planet and click on “create.”

Three funny little animated puzzles can be accessed for free on Learn 4 Good. I was surprised to find that the site asks you to pay for the fourth puzzle, given all the free puzzles on the web.

Finally, there’s a bartender game, “The Right Mix,” in which you mix drinks, one at a time, then shake and serve. The best part is the bartender’s reaction after he tastes the concoction. Unfortunately, the exercise does not improve one’s skill as a bartender.

Ken Balcomb calls for further review of orca’s death

Thursday, March 6th, 2014

Ken Balcomb, the dean of killer whale research in Puget Sound, is asking federal authorities to reopen the investigation into the death of L-112, a young female orca who died two years ago of mysterious causes.

Ken Balcomb

Ken Balcomb

Ken maintains that an underwater “blast” remains the mostly likely cause of death for the whale, who was known as Sooke — or Victoria, as Ken originally named her.

A draft final report (PDF 2.3 mb) by the National Marine Fisheries Service, dated Feb. 24, states that “blunt trauma to the head and neck is the prime consideration for the cause of mortality. Despite extensive diagnostic evaluation, the cause of the head and neck injuries could not be determined.”

See Water Ways, Feb. 25, for a discussion of the final report and links to other stories.

The official investigation could find no military operations in the area off the Washington/Oregon coast, where the young whale was found dead on Feb. 11, 2012. In looking for a cause of the trauma, the report essentially rules out several underwater explosions set off by the Canadian Navy a week before, on Feb. 4, 5 and 6 off Vancouver Island. These activities occurred too far north — and prevailing winds and currents were in the opposite direction, according to the report.

But Ken Balcomb argues that the report fails to fully consider how L-112 could have ended up south of these military exercises. Currents are not certain, he said. They can change, and eddies can even flow in the opposite direction from prevailing currents. Ken also raises the prospect that a dead or dying orca calf could be carried a great distance by other members of the pod.

“I consider the evidence presented in the NMFS report to be selected and filtered to depict a preferred hypothetical scenario, rather than one that may be more realistic,” he wrote to NMFS, the federal agency in charge of protecting marine mammals.

Ken’s 12 pages of comments (PDF 1.1 mb) address numerous statements in the report, and here are a few:

On the brain:

Report: “The absence of right cerebral hemisphere and right cerebellum of the brain was secondary to loss of tissue during disarticulation of the head. Significance is uncertain based on imaging alone, but unilateral loss of brain tissue is unusual.”

Ken’s comment: “UNUSUAL! The right cerebral hemisphere and cerebellum were completely mushed and there was evidence of hemorrhage in the calvarium, both significant findings of brain damage from a blast impact. The observation is consistent with blast trauma.”

On the ear bones:

Report: “The CT results showed no evidence of bone fractures or damage to the middle or inner ear bones. These results do not conflict with gross observations and the proposed cause of acute or peracute death by blunt force trauma; however, blast- or seismic-related injuries cannot be
entirely discounted.”

Ken’s comment: ”Upon gross dissection both tympanic bullae were found to be dislocated from their fragile bony pedestals anchoring them to the cranium. While it may be accurate to say that no evidence of fractures or damage to the middle or inner ear bones on the CT scans, it is misleading to infer that no damage was evident to the ears (see page 11 of Necropsy report).”

On possible attack by another marine animal:

Report: “The primary signs of injury reported from aggressive attacks are rake marks, musculoskeletal and/or intra tissue trauma (bruising, tearing) attributed to ramming and sometimes death. Contrary to the cases reported in the literature, L-112 was a juvenile animal (older and larger than a calf or neonate), and the examiners did not document tooth rake marks associated with the signs of hemorrhage they observed during the gross examination. Nevertheless, we cannot rule out the possibility that L-112 suffered injuries from an aggressive attack, such as ramming, by a larger animal.”

Ken’s comment: “The presumed hypothesis suggested by the last sentence is absolutely preposterous, given the evidence of a massive single traumatic event causing the mortal injury. To not rule out the attack hypothesis while ruling out blast trauma is ludicrous.”

On currents:

Report: “Because of prevailing currents and eddies it is unlikely that L-112 died in Canadian waters or the Strait of Juan de Fuca and drifted south, but instead likely died in the Columbia River plume or farther to the south along the coast of Oregon. Given the state of decomposition at the time of stranding the body was either carried by eddies for several days or may have drifted a substantial distance from the south before being trapped by the eddies and cast ashore on the Long Beach Peninsula.”

Ken’s comment:
“The drift patterns can be quite different from year to year, as well as from season to season, or even week to week. It is regrettable that drifters were not deployed near the west entrance to the Strait of Juan de Fuca in February 2012. There was a NOAA cruise in these waters at that time, and I asked the chief scientist to deploy drifters or some identifiable devices to ascertain the real time drift pattern at that time. One can surmise from the temperature regimes that were documented real-time that there was an anomalous cold water regime moving in a southerly direction in February 2012, but there were no current measurements.”

On the possibility of transport by another orca

Ken’s comment:
“I further request that the investigation team thoughtfully consider the relevant cetacean epimeletic behavior … (He mentions two studies.) Hoyt (1981) in ‘Orca, the Whale Called killer” on page 92 states: ‘Among cetaceans, and especially the dolphin family (including orca), care-giving behavior to sick or wounded family members seems exemplary. Moby Doll was supported by members of his family after he was harpooned in 1964. On another occasion off the B.C. coast, a young killer whale was hit by a government ferry boat, the propeller accidentally slashing its back. The ferry captain stopped the boat and watched a male and a female supporting the bleeding calf. Fifteen days later, two whales supporting a third – presumably the same group — were observed at the same place.’”

Ken concludes his remarks with this: “These comments are dedicated to L86 and L112, the most overtly affectionate mother/offspring pair of whales I have ever seen. Rest in peace, L112. We miss you.”


Larry Rutter’s legacy connected to salmon recovery

Thursday, February 27th, 2014

I was saddened to hear of the death of Larry Rutter, senior policy assistant in the Sustainable Fisheries Division at the National Marine Fisheries Service and a U.S. commissioner on the Pacific Salmon Commission.

Larry Rutter

Larry Rutter

Larry, 61, was one of the folks who taught me the basics of salmon management more than 20 years ago. He kept me informed through some difficult negotiations over salmon harvest allocations between the U.S. and Canadian governments.

Technically, he was very sharp. Personally, he was patient and kind.

I am pleased that Long Live the Kings has created a Larry Rutter Legacy Fund to carry out his wish for remembrances connected to the Salish Sea Marine Survival Project, an effort he helped coordinate across the border between LLTK and the Pacific Salmon Foundation in Canada.

“It was due in no small part to Larry’s influence that LLTK and PSF were awarded a $5-million grant from the Pacific Salmon Commission’s Southern Fund Committee in 2013 for the Salish Sea Marine Survival Project,” said LLTK Executive Director Jacques White in a statement. “Without his vision and dedication, we simply would not be where we are today.”

To donate to the Larry Rutter Legacy Fund, scroll to the bottom of the Long Live the Kings page on the topic.

Larry was a graduate of South Kitsap High School and the University of Washington. He worked for the Point No Point Treaty Council and Northwest Indian Fisheries Commission before taking the job with NMFS (NOAA Fisheries). His obituary in The Olympian says Larry died last Thursday of pancreatic cancer.

Mystery of L-112′s death may never be solved

Tuesday, February 25th, 2014

It appears we’ll never know what killed L-112, known as Victoria or Sooke, found dead at 3 years old, after she washed up on an ocean beach in Southwest Washington.

L-112 in happier times. The 3-year-old orca died in February 2012, and the cause of her death remains a mystery.

(Click on image to see Jeanne's tribute page)

If you recall from two years ago, much speculation swirled around the notion that the female orca was killed by military operations, such as sonar or an explosion. The Royal Canadian Navy confirmed the use of sonar and small underwater detonations west of Vancouver Island. But that was far from Long Beach, where the orca washed up, and ocean currents suggest she was killed even farther south. For a quick history, see Water Ways from Feb. 18, 2012, followed by an entry on May 16, 2012.

The latest report concludes, as early ones did, that L-112 died from “blunt force trauma.” But the cause of the trauma could not be determined. No sonar activity or explosions were identified in the area where her death probably occurred, although a physical examination was not able to totally rule out those causes.

A new bit of information emerges from the long-term acoustic recorders that listen for sounds off the coast. Calls identified as coming from L pod were reported near Point Reyes in California on Jan. 30, off Westport in Washington on Feb. 5, and near Newport in Oregon on Feb. 20. L-112 was found dead on Feb. 11 after floating for several days. It appears likely that the young whale was with her pod at the time of her death.

As the report states:

“This multi-disciplinary investigation could not determine the source of the blunt trauma despite gathering and evaluating all available information on the whales, the environment, and human activities. We evaluated the sighting history of the whales to provide insight into the circumstances of the stranding.

“Autonomous passive acoustic recorders off the coasts of Washington, Oregon, and California indicated that the main group of L Pod, possibly including L-112, was off California in late January, heading north, and possibly off Westport, Washington in the first week of February and detected near Newport, Oregon after the stranding…

“A major source of trauma from sonar, explosives, or a seismic event would likely have affected multiple individuals traveling together as killer whales are known to do. All other members of L-112’s family group were sighted following L-112’s stranding. No other members of the L4 sub-group were reported missing, injured, or stranded between the time of the L-112 stranding and the summer of 2012.

“This observation leads us to believe that the trauma suffered by L-112 was likely borne individually and was not an event that covered a large area or that directly impacted the young whale’s most likely traveling companions in the L4 sub-group. For these reasons, we do not believe that L-112 succumbed to blast injuries or exposure to other high intensity sound.”

So was L-112 struck by a ship? Did she encounter another aggressive whale or large shark? Or was she hit by another unknown force or object? We’ll probably never know, as the mystery goes on and on and people continue to ask, “Who killed L-112?”

To review a copy of the report, go to the website “Wild Animal Mortality Investigation: Southern Resident Killer Whale L112 Final Report.”

Any ideas for a no-discharge zone in Puget Sound?

Tuesday, February 25th, 2014

Washington Department of Ecology is pushing ahead with its plan to create a “no-discharge zone” for Puget Sound, which would prohibit the discharge of sewage from boats, even those with a Type II marine sanitation device. Check out my story last week in the Kitsap Sun, Feb. 19 (subscription).

Proposed no-discharge zone for Puget Sound // Washington Department of Ecology

For many people, it is disconcerting to think about mobile toilets traveling everywhere in Puget Sound and discharging their waste anywhere and at any time.

Kitsap Public Health District has gained a reputation for tracking down sources of pollution and getting them cleaned up. If you have a failing septic system, for example, you are expected to get it fixed. Many of the Dyes Inlet beaches between Bremerton and Silverdale were reopened to commercial shellfish harvesting, thanks in no small part to these persistent efforts to clean up bacterial pollution.

Sewage-treatment plants still discharge some bacteria, despite advanced treatment processes. Consequently, shellfish beds are permanently closed around treatment plant outfalls, with the closure zone dependent on the level of sewage treatment. And when there are sewage spills, long stretches of beach may be closed to shellfish harvesting for 10 days or longer.

When they are working properly, Type II marine sanitation devices aboard boats are fairly good at killing bacteria, although levels are still above state water-quality standards. Less certain is what happens to human viruses, including hepatitis, that may not be killed. In addition, marine toilets release chemicals — such as chlorine, quaternary ammonia and formaldehyde — into the water.

It’s not hard to see why the goal would be to eliminate discharges of boater waste into Puget Sound, assuming that sufficient pumpout stations exist for people to offload their waste. Pumpout stations are connected to sewage-treatment systems, which do a better job of disinfection and remove most solids that can contribute to algae blooms and low-oxygen conditions.

Creating a no-discharge zone is one goal of the Puget Sound Action Agenda (PDF 16.4 mb) developed by the Puget Sound Partnership.

Ecology Director Maia Bellon seemed to strike the right tone when she announced the petition for a no-discharge zone (PDF 8.1 mb) in Puget Sound:

“We want to reach out and invite comments, questions and suggestions over this draft proposal. We’re working with boating, shipping and fishing leaders, and now is the time for broader perspective and feedback. Everyone who lives here has a vested interest in a healthy Puget Sound.”

Her approach leaves the door open to some creative solutions for getting everyone in compliance with the no-discharge zone. As I showed in last week’s story, the no-discharge zone could be a hardship for some tugboat and fishing boat operators. One estimate for converting a tugboat is $125,000.

Ecology’s solution so far has been simple: Give those without holding tanks three years to install the tanks and plug up theirs discharge pipes.

Other solutions may be possible, although they could create administrative burdens for Ecology. What about the idea of creating an exemption for boats that have no holding tanks? Boat owners could pay an annual fee for the exemption, and the money could go into a fund to assist owners with the cost of conversion. Maybe a conversion should be required, if necessary, at the time a boat is sold. It’s just an idea.

When applying for an exemption from the no-discharge zone, boat owners should agree to discharge treated wastes at a safe distance from the beach. Maybe they should be required to know where certified shellfish beds are located and stay even farther away.

I realize these ideas would complicate a simple plan, and maybe there are better ideas. In general, I believe that a reasonable solution should be proportional to the problem. We should not kill a rat with heavy explosives, while ignoring the cost of repairs.

To see how more than 20 other states are addressing no-discharge zones, visit the Environmental Protection Agency’s website on vessel sewage discharges and a state-by-state breakdown of no-discharge zones.

When I broke this story in September, I interviewed others who had thoughts on the issue. See Kitsap Sun, Sept. 25 (subscription).
