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.”

Thoughts run to an orca called Granny and her clan of five generations

Looking back on the various comments that followed the death of the killer whale named Granny, I realized that there were a couple of thought-provoking tributes that I never shared with readers of this blog.

Granny, designated J-2, was believed to be more than 100 years old, and she was the obvious leader for many of the Southern Resident orcas that frequent Puget Sound. Granny went missing last fall and was reported deceased at the end of the year by the Center for Whale Research. See Water Ways, Dec. 30.

Some tributes to Granny were written and posted soon after her death notice, including one by Ken Balcomb of the Center for Whale Research. I posted my thoughts along with some others in Water Ways on Jan. 4.

Seals and sea lions may be undercutting chinook and orca populations

Seals and sea lions can no longer be ignored in the effort to recover our threatened Puget Sound chinook salmon or our endangered killer whales.

A new study shows that seals and sea lions are eating about 1.4 million pounds of Puget Sound chinook each year — about nine times more than they were eating in 1970, according to the report. Please read the story I wrote for the Encyclopedia of Puget Sound, also published in an abridged version in the Kitsap Sun.

Seals and sea lions in Puget Sound get the first chance to catch the chinook as they leave the streams and head out to the ocean. Since they are eaten at a very young age, these small chinook, called “smolts,” never grow into adults; they never become available for killer whales or humans.

Based on rough estimates, as many as one in five of these young fish are getting eaten on their way out of Puget Sound. If they were to survive the seals and sea lions and one factors in the remaining mortality rate, these fish could translate into an average of 162,000 adult chinook each year. That’s twice the number eaten by killer whales and roughly six times as many as caught in Puget Sound by tribal, commercial and recreational fishers combined, according to the study.

Granny, the orca, was seen in poor condition before her death

About a month before the Center for Whale Research last observed Granny, the killer whale, the elder orca was pictured in aerial photos by researchers from NOAA’s Southwest Fisheries Science Center.

The last aerial photos of Granny showed her to be in “poor body condition,” according to a report from marine mammal researcher John Durban on NOAA’s website.

Granny, designated J-2, was missing for weeks before the Center for Whale Research gathered enough observations to announce her death on the last day of 2016. The oldest whale in the three Southern Resident pods could have been more than 100 years old, according to estimates, as I discussed in Water Ways on Jan. 4.

The aerial photos, taken from a small unmanned hexacopter, are used to monitor the health of the orcas, John noted in his report. The photos taken in September show Granny to be thinner than other adult females. The photos on this page show Granny (top photo) to be thinner than J-22, a 32-year-old female named Oreo (second photo) who was reported in “robust condition” and may have been pregnant.

Granny, a killer whale unlike any other, stayed graceful to the end

If we can celebrate the life of a person who has died, it seems fitting to me that we should celebrate the long, productive life of a killer whale known as Granny.

Granny, officially designated J-2, was the oldest orca in the three pods of Southern Residents. Possibly more than 100 years of age, her longevity is something we can only hope to see among the other orcas that frequent Puget Sound.

Granny was the longtime leader of J pod. In a matriarchal society like the orcas, offspring stay with their mothers for life. Generally, the older females lead the way, and Granny was almost always seen at the front of the pack as J pod moved through the Salish Sea.

For a long-lived intelligent orca, it is hard to imagine the amount of knowledge she must have accumulated through the years. I tend to think that Granny had a personal history with nearly every cove and inlet in the Salish Sea. I think she understood the movement of salmon and where the fish would congregate before heading up the streams. It must have been tough for her to watch the decline of the whales’ once-abundant prey.

Death toll for 2016 includes six orcas
from the Salish Sea

UPDATE, Jan. 2
The Center for Whale Research has announced that J-2, known as “Granny,” has apparently died. The oldest orca among the three Southern Resident pods, Granny was one of the first Southern Residents identified when Ken Balcomb began his Orca Survey in 1976. At the time, she was estimated to be at least 45 years old and probably in her 70s, putting her likely age at more than 100. Ken’s tribute to Granny can be read on the Center for Whale Research website. More to come.

When it comes to the killer whales that frequent Puget Sound, a year can make all the difference in the world. Last year at this time, we were celebrating a remarkable baby boom — eight new orca calves over the previous 12 months. See Water Ways, Dec. 16, 2015.

Another new baby was added in January of this year, for a total of nine. But if 2015 was the boom year, then 2016 turned out to be a major bust, with six orca deaths recorded during the calendar year.

The latest death among the Southern Residents was J-34, an 18-year-old male named DoubleStuf. He was found dead floating near Sechelt, B.C., northwest of Vancouver, on Dec. 20. Check out the tribute and wonderful photos on Orca Network’s webpage.

Sea Shepherd encounters Japanese whalers at start of summer season

It has just turned winter in the Northern Hemisphere, which means that it is now summer in the Southern Hemisphere. The Japanese whaling fleet has entered the Southern Ocean to kill up to a self-designated quota of 333 minke whales, and Sea Shepherd has given chase.

We have heard the story before, and many of us have watched the drama play out during six seasons of the TV series “Whale Wars” on Animal Planet. This year, Sea Shepherd hopes to have an advantage with a ship declared to be faster than the Japanese whaling vessels, as I explained in Water Ways at the end of August.

On Dec. 3, the Sea Shepherd vessel Steve Irwin left Melbourne, Australia, for the Southern Ocean for its 11th campaign against the whalers. The Steve Irwin was followed a day later by the new ship, Ocean Warrior. Yesterday, the Ocean Warrior located one of the Japanese harpoon vessels, the Yushin Maru, inside the Southern Ocean Whale Sanctuary, according to Capt. Adam Meyerson, the skipper of the Ocean Warrior.

“The crews of the Ocean Warrior and the MV Steve Irwin have been battling through thick fog and ice to protect the whales in the Australian whale sanctuary,” Meyerson said in a news release. “The Yushin Maru was hiding behind an iceberg and came out on a collision course.

“Finding one of the hunter-killer ships hiding behind an iceberg in a thick fog means that the rest of the fleet is nearby,” he added. “We all hope to have whaling in the Southern Ocean shut down by Christmas.”

Amusing Monday: Mysterious ocean sounds are not always ‘creepy’

Some underwater ocean sounds remain a mystery, while other sounds are well understood by NOAA’s Pacific Marine Environmental Laboratory.

PMEL’s acoustic division continues to find unusual sounds within its long-term mission of recording and measuring ocean noise and assessing potential problems created by noisy humans.

Sounds ranging from whale calls and volcanoes to cargo ships and airguns are monitored by the Pacific Marine Environmental Laboratory with the help of 11 Ocean Noise Reference Stations from Alaska to the South Pacific. Graphic: NOAA's Pacific Marine Environmental Laboratory

I remain intrigued by ocean sounds, and I can’t help but worry about sensitive marine creatures, such as whales, that must live in our modern world of noisy ships and machinery.

One mysterious sound nicknamed “Upsweep” was present when PMEL began recording on the Navy’s SOSUS (Sound Surveillance System) array in August 1991. The sound, which consists of a series of upsweeping sounds, is loud enough to be heard throughout the Pacific Ocean, according to PMEL’s website. This sound was speeded up 20 times to be more easily heard.

Death of female orca with young son raises worries about the future

It has been hard to take the news that J-28, a 23-year-old female killer whale named Polaris, is now missing and presumed dead — even though I knew this news has been coming since August. It now appears likely that her 11-month-old son J-54, named Dipper, will not survive either.

On Oct. 2, J-28, named Polaris, was photographed with an indentation behind her blow hole, a condition known as “peanut head.” Polaris has now been confirmed as dead, and her son is probably dead as well, researchers say.

I sadly reported on Polaris’ “super-gaunt” condition in Water Ways (Aug. 24) after talking to Ken Balcomb of the Center for Whale Research. Until recently, various whale-watching folks, including CWR researchers, have reported that Polaris was still alive. She was generally seen moving slowly and in poor shape, but at times she seemed to have more energy, raising hopes that she might recover. But the last sighting of Polaris was Oct. 19 in the Strait of Juan de Fuca.

During a press conference Friday, Ken announced the death of Polaris, as he spoke out to raise awareness about the plight of Puget Sound orcas.

Ken said Dipper’s sister and aunt were attempting to care for the young orphan, but no other lactating females have moved in to provide milk, so he likely will die if he is not already dead.

Ken read a personally penned obituary for Polaris, noting that she was popular with whale watchers, in part because she was easily identified by a nick in her dorsal fin. She acquired the distinctive mark when she was nine years old.

At the press conference, Ken talked about the most concerning problem facing the orcas: a shortage of chinook salmon, their primary prey. The food shortage is exacerbated when the whales burn fats stored in their blubber, causing the release of toxic chemicals from their blubber into their bloodstream. Chemicals can affect the immune and reproductive systems, as well as other hormonal systems.

Amusing Monday: The evolution and danger of packaging drinks by six

When I was a young child, we didn’t have to worry about wildlife getting strangled by six-pack rings, because these plastic binders for cans had not been invented yet. I was 9 years old in 1961 when this simple, convenient form of packaging was invented, so I clearly remember the transition. (See Hi-Cone history.)

At the time, nobody predicted the conservation consternation that would be created by such a simple piece of plastic. During the 1970s and up to present, pictures of entrapped birds and other sea creatures became common, suggesting that we at least cut the plastic to save the animals. The first video provides a story of potential revenge.

Before the invention of six-pack rings, people bought soft drinks and beer in cardboard packages, which sort of wrapped around the cans. Pabst Blue Ribbon may have been the first beer sold in cardboard cartons (second video), although Coca Cola may have started the phase. The Coke company claims to be the first to take its bottles out of wooden crates and begin offering cardboard packaging for consumers as early as 1923.
