The noon trip on the Ocean Magic II was exciting to see the whales in the swells of the choppy sea. K pod was further north of Lime Kiln traveling south while J pod was further south heading north. Both family groups milled about and foraged in the area. The animals were quite dynamic by breaching in the active water. On the afternoon trip we met up with K pod traveling south off Stuart Island. Lummi the oldest southern resident female, 96 years old, was sighted as was Sequim / K12. Sequim’s youngest offspring Rainshadow / K37 was sighted proposing with Raven's new calf born last month K39.

Kelping off Victoria

On today’s noon trip on the Ocean Magic II all three pods were sighted together, traveling east off the shoreline of Victoria. While K pod went around Trial Island, the others swam close to shore through Enterprise Channel. The whales took advantage of the kelp beds as they swam slowly and ‘kelped’, rubbed their flukes and dorsal fins through the smooth blades of brown algae. We later headed over to Race Rocks Ecological Reserve and viewed the female elephant seals that are quite rare for this area.

Northern elephant seals have post-reproductive feeding excursions in the open sea for more than two months. Male range is typically further north than females. They forage for fish and squid at depths between 300 and 1500m for up to 25min by slowing heart and metabolic rates. The males are larger than females, as is their proboscis, which is used for dominance by production of loud repetitive vocalizations in crowded rookeries. Dialects are distinctive between regions (Le Boeuf and Pentrinovich 1975).

L pod

Oceansun / L25


Today’s noon trip on the Ocean Magic II brought us north of Henry Island were we found L pod in a resting line. Whales rest by shutting down activity in one half of their brains so they can still use the other half to voluntarily respire. Oceansun / L25 a 78 year old female seemed to wake before the others as she spy hopped twice nearby and traveled south for a bit, perhaps in pursuit of prey, before heading back to the resting group.

US Navy Sonar Testing

FACING LAWSUIT, NAVY DECLARES ITSELF ABOVE THE LAW IN HIGH-INTENSITY SONAR FIGHT

Underwater Sonic Assault Threatens Marine Mammals Near New Ocean Sanctuary; Pentagon Rejects Simple Steps to Fix Longstanding Problem Before Giant War Game

LOS ANGELES (June 30, 2006) - With the U.S. Navy facing a lawsuit to stop its illegal use of high-intensity sonar in a massive practice exercise that began this week, the Pentagon today took the unprecedented step of declaring the military exempt from the basic law protecting whales, dolphins, and other marine mammals. The drill is taking place in a 210,000 square nautical mile area near the Northwestern Hawaiian Islands Marine National Monument, created just two weeks ago by President Bush.

The suit was filed on Wednesday by the Natural Resources Defense Council (NRDC) and other conservation groups after the Navy ignored requests for a safe resolution of the problem and forged ahead with its sonar plans for the biennial Rim of the Pacific (RIMPAC) maneuvers. High intensity, mid-frequency sonar is a technology that has been directly associated with mass strandings of marine mammals around the world.

"This is an historic and unprecedented retreat by the U.S. Navy from our national commitment to protect whales, dolphins and other marine life," said Joel Reynolds, a senior attorney at NRDC and director of its Marine Mammal Protection Project. "It's not that the Navy can't comply with the law; it's that the Navy chooses not to."

In a two paragraph memorandum, Deputy Defense Secretary Gordon England excused the Navy for a period of six months from any and all provisions of the Marine Mammal Protection Act (MMPA) in its use of high-intensity, mid-frequency sonar. The memo from Deputy Secretary England states that in that period, the Navy will work with "the Department of Commerce to address the regulatory authorization process and expedite the analysis and regulatory steps necessary to come into full compliance with the requirements of the Marine Mammal Protection Act." (Click here for PDF file of memo.)

In other words, the Pentagon today acknowledged that its use of mid-frequency sonar does not comply with the Marine Mammal Protection Act.

Numerous mass strandings and mortality incidents have been associated with sonar use, including events in Hawaii, Washington State, North Carolina and the Bahamas. Whales exposed to high-intensity sonar have been found bleeding from the eyes and ears, with lesions in their organ tissue. Biologists worry that whales found dying on beaches are only the tip of an iceberg, and that many more are dying at sea.

"Whales and other marine mammals shouldn't have to die for practice," said Reynolds. "The Navy has more than enough room in the oceans to train effectively without injuring or killing endangered whales and other marine species. When the Navy decides to stage a war game in the middle of some of the richest underwater habitat on earth, it is legally obligated to take simple, common sense steps to protect that ecosystem."

Among preventive measures that the Navy has refused to accept: a larger safety zone at all times around the sonar source, as the Navy uses for other sonar systems; adding an extra spotter on board ships during all sonar training; reducing the sonar power level at night or at other times when spotters' visibility is compromised; and avoiding areas in or near significant marine mammal habitat like whale breeding and feeding areas and migratory routes.

During the last RIMPAC exercise in 2004, a group of over 150 melon-headed whales stranded in Hanalei Bay on the island of Kauai following a Navy sonar exercise. After that incident, NRDC and other organizations approached the Navy about the need for planning, review, and mitigation measures to prevent a recurrence. The filing of litigation this week followed the Navy's refusal to include adequate protective measures or to obtain legally required permits and review.

Despite the Marine Mammal Protection Act exemption invoked today by Deputy Secretary England, the groups say the Navy is also operating in violation of the National Environmental Policy Act, and they plan to vigorously pursue the pending lawsuit regardless of today's action.

"The rule in this country has always been that no one is above the law, including the military," said Richard Kendall, a litigation partner at the Los Angeles law firm of Irell & Manella and co-counsel for plaintiffs in the lawsuit. "We intend to continue our efforts to force the Navy to mitigate its sonar use in RIMPAC by prosecuting the Navy's other violations of law."

The lawsuit was brought by NRDC in conjunction with the International Fund for Animal Welfare, the Cetacean Society International, the Ocean Futures Society, and Jean-Michel Cousteau. It was filed in the U.S. District Court for the Central District of California, in Los Angeles.

Superpod!

All three pods were in spread out today along the west side of the San Juan Island. We met up with the whales off Hanna Heights as they foraged and traveled north. The new K pod baby, K39, was sighted and the whales were quite active with lots of repeated breaches and vocalizations.

An amazing day on the water with K and L pods. The whales were quite active with lots of percussive behaviour, aerial scans, and a synchronized spyhop by two individuals! Flash / L73 and was identified as well as Hugo / L71.

Offshore Killer Whale

A third group of killer whales, called offshores, have been discovered as a distinct population off the coast of North America. They are found in large groups of 30 to 60 individuals. They have been seen as far south as southern California and as far north as southeast Alaska. They are smaller than resident and transient killer whales. Their dorsal fin shape and mottled saddle patches resemble resident killer whales suggesting a closer common ancestor than with transients. Offshores have been recorded emitting discrete call types and their teeth are ground down from suspected shark prey.

On August 29, 1997 a dead killer whale was reported drifting 17 miles
offshore. It took the Strawberry Isle Marine Research Society’s small research boat eleven hours to tow the carcass to Strawberry Isle, with many re-fueling visits from whale-watching boats. The 5.5m (18ft) female orca’s saddle patch and dorsal fin identified her as O120, a member of the elusive offshore group of killer whales. No clear cause of death was found, though her heavily worn teeth and thin blubber suggest that she may have been old and far removed from her home in more southern waters.

After year of bleaching the bones in the sun, Society member Dominique Dupuis (Pipot) and a crew of volunteers put in close to 700 hours scrubbing and treating the bones with a non-toxic penetrating epoxy. Pipot and Robinson Cook created the ingenious orca-sized framework that supports the skeleton. The Build-A-Whale exhibit has inspired people in classrooms and at community events all over Vancouver Island, and will continue touring after it leaves the BC Experience.

SRKW Symposium

Southern Resident Killer Whale Symposium 2006
NOAA NW Fisheries Science Center, Seattle, WA. Apr 3- 5

There have been approximately 650 oil spills in the Puget Sound area since 1985. In 2006, NOAA developed a response team, tug, and increased safety standards for single-hulled ships. The maximum number of Southern resident killer whales occurred in 1996 at 97 individuals. The United States has two protection acts. The goal of the Marine Mammal Protection Act (MMPA) is to restore stocks to optimum sustainable levels. The goal of the Endangered Species Act (ESA) is to develop protective, regulations, define critical habitat, and develop a Recovery Plan. Critical habitat is defined as the biological and physical elements essential for conservation. In 2001, a petition was submitted to the ESA committee to list the southern residents as ‘endangered’. In 2002, the committee voted not to list the population as endangered on the fact that they are not recognized as a separate species. In 2003, this population was listed as ‘depleted’ under the MMPA. In 2004, the southern residents were listed as ‘threatened’ as a ‘distinct population segment’ (DPS). The population was determined as significantly different because of is distinct acoustic and behavioral cultural traits, genetics, and morphology. Culture is defined as learned knowledge or behavior passed though generations that are important for survival. For example, the southern residents engage in greeting ceremonies whereas the northern residents beach rub. In 2005, a MMPA Conservation Plan was developed. On February 16 2006, the southern residents were officially listed as ‘endangered’ under the ESA. Research is needed on sound, prey, and toxic pollution. Canada implemented the Species at Risk Act (SARA) in 2003 to designate habitat and develop Action, and Recovery, Plans for species at risk (SAR). Species at risk are defined as those with ‘threatened’ or ‘endangered’ listings. There are four ecotypes of killer whales in British Columbia, southern and northern resident (fish-eating), offshores, and transients (meat-eaters). The southern residents are listed as ‘endangered’, the northern residents as ‘threatened’, the offshores as of ‘special concern’, and the transients as ‘threatened’. Within a year of listing, Action and Recovery Plan are developed. Transient killer whales were listed as ‘threatened’ in 2006 and thus require plans by 2007. The plans for the residents are to promote long-term viability, preserve geographic conditions, and preserve matrilines with multiple generations. Objectives; adequate and accessible food supply, chemical and biological pollution, disturbance from human activity, critical habitat and acoustic environment protection. The management process is to monitor, determine, investigate, and identify threats. The precautionary principle must be untilised because for long-lived species we may never know long-term effects.

West Coast Birds Dying

Thousands of seabirds dying along the coast of B.C.

Published: Friday, February 24, 2006
Countless thousands of seabirds are mysteriously washing ashore dead along the B.C. coast this winter from the west coast of Vancouver Island to the Queen Charlotte Islands.

"It's spooky to see them coming in like that," Pete Clarkson, assistant chief warden at Pacific Rim National Park Reserve at Long Beach, said Thursday in an interview.

The massive die-off of seabirds this winter follows the near-complete failure of at least two seabird nesting colonies last spring.

About 1,000 glaucous-winged gulls failed to successfully breed at Cleland Island, a provincial ecological reserve northwest of Tofino, while about 400 glaucous-winged gulls and 300 rhinoceros auklets failed to breed at Seabird Rocks, south of Barkley Sound.

Curiously, up to 200 of the gulls successfully bred at Florencia Islet north of Barkley Sound, a colony that might have benefitted from its location just two kilometres from a local garbage dump.

"That's the only thing I can think of," Clarkson said. "It's a strong suspicion."

Thousands of seabirds were also reported washing ashore or breeding with poor success on the U.S. Pacific coast between California and Washington, including the mass starvation deaths of murres on Tatoosh Island off the Olympic Peninsula.

U.S. scientists speculate the deaths may be associated with warmer weather and changes in winds and currents that might have reduced the availability of the birds' marine food.

Clarkson said the first wave of seabirds, red phalaropes, began washing ashore in large numbers around last Christmas on the beaches of Pacific Rim park. The small shorebirds looked emaciated. "They appeared to be starving, minimal body fat," he said.

Northern fulmars, western grebes, common murres, and rhinoceros auklets were among the seabird species that washed ashore at the Carmanah light station.

Clarkson noted that a similar die-off of phalaropes occurred about three years ago. An examination of their gizzards found plastic pellets or nodules produced for manufacturing consumer products. These pellets find their way into the ocean only to be ingested by seabirds feeding on the surface.

While these plastics pose an environmental and ecological problem, they are not thought to have caused the death of the phalaropes, Clarkson said.

Then, after last Christmas and into January, large numbers of Cassin's auklets began washing ashore on the west coast of Vancouver Island. "I sense it's specific to a food source, or somehow a problem in that food web," Clarkson said.

Surveys found three to seven dead auklets per kilometre on beaches in the park.

On the east coast of the Queen Charlottes, officials also reported large numbers of ancient murrelets, marbled murrelets, and Cassin's auklets being found dead.

The total number of birds dead all along the coast would have ranged into the thousands, he said.

Various bird carcasses have been sent to the provincial lab in Abbotsford for analysis, while federal scientists with the Canadian Wildlife Service in Delta and Sidney gather information in an effort to find the cause of the massive die-off and consider the implications on overall populations.

Ambergris - Grey Amber

Whale 'vomit' sparks cash bonanza

(Image: ambergris.co.nz)


An Australian couple who picked up an odd-looking fatty lump from a quiet beach are in line for a cash windfall.

Leon Wright and his wife took home a 14.75kg lump of ambergris, found in the innards of sperm whales and used in perfumes after it has been vomited up.

Sought after because of its rarity, ambergris can float on the ocean for years before washing ashore.

Worth up to $20 a gram, Mr Wright's find on a South Australian beach could net his family US$295,000 (£165,300).

At first, Mr Wright and his wife Loralee left the strange lump on the beach where it was found.

However, two weeks later the couple returned to Streaky Bay and found it still lying there. Curious, Mrs Wright persuaded her husband to take it home.


AMBERGRIS FACTS

Found in warm water oceans around the world
Bile secreted by sperm whales as a digestion aid
Solidifies and floats on water, sometimes for years
Used in perfumes, medicines, flavourings
Banned in US under endangered species legislation

Internet investigations failed to resolve the mysterious matter of the lump's identity, so the couple turned to local marine ecologist Ken Jury for help. "I immediately decided it was ambergris - it couldn't be anything else," Mr Jury told Australia's ABC radio.

Mythologised for thousands of years, ambergris has been referred to as "floating gold" by scientists and scavengers who long for a windfall amid the surf.

Expelled from the abdomen of the giant sperm whale, often while hundreds of kilometres away from land, ambergris is a natural excrement thought to be used by the whale as a digestion aid.

The hard beaks of giant squid, a main source of food for the whale, have often been found inside lumps of ambergris.

Initially, ambergris is a soft, foul-smelling waste matter that floats on the ocean.

But years of exposure to the sun and the salt water of the ocean transform the waste into a smooth, exotic lump of compact rock that boasts a waxy feel and a sweet, alluring smell.

"It's quite remarkable when you think about it, because when the whale throws this out, it's discarded material that they can't digest," Mr Jury explained.

"[But] after 10 years, it's considered clean and all you're getting then is the wonderful musky, very sweet perfume, which I've got to say is ultra smooth - it's unbelievable."
