BC Resident Grey Whales and Sea Otters
The following photos were taken near Flores Island, Clayoquot Sound on May 13, 2009. We encountered the same whale on two different occasions and is easily recognized by the local tour boat captains as a regular summer resident grey whale though its light coloured head and unique markings. There were other grey whales in the large outer swells and foraging in the bays off the west coast of the island but this individual seemed to prefer the more sheltered east and south sides that day.

Sea otters were spotted near the area and are a successful 1960s translocation experiment from the Aleutian Islands after being hunted to extinction in British Columbia during the fur trade 1700-1800s. In 1911, an international treaty protected the sea otters allowing existing populations in Alaska to grow.

Robson Bight salvage set to begin
At long last, the salvage of the diesel fuel tanker that fell to the bottom of Robson Bight, on August 20th 2007 is set to begin. A barge laden with salvage equipment is anchored over the site, and a 30 person crew from Mammoet Salvage, a Dutch company, and Seattle based Global Diving & Salvage, has been busily getting everything ready for the operation over the past few days. Local First Nations and NGOs are also involved, helping to monitor the sensitive environment surrounding the Ecological Reserve that was created in 1982 to protect vital orca habitat. The salvage will probably begin tomorrow (May 13th). Giant anchors have already been deployed to keep the barge in place. Today, a small remotely operated vehicle (ROV) equipped with cameras is inspecting the underwater site. Hopefully, this inspection will ensure that the tanker truck and other debris are located exactly where they were when last seen in December 2007.
Hopefully, too, the inspection will determine that the condition of the diesel tanker truck has not deteriorated to the point where it will break apart when moved. To help avoid the possibility of a spill of diesel oil during the tricky lifting part of the operation, a metal box (yellow in the photo at http://www.orcalab.org) will first be lowered over the tanker truck, which will then be secured inside the box. A huge crane on the barge will lift the box and its deadly cargo to the surface. When the load reaches 10m below the surface, divers will inspect the box and tanker, to determine whether any diesel has leaked during the lift. If there are no leaks, the box and tanker will be hoisted onto the deck of the barge. At that point, the diesel will be pumped out of the fuel tanker into another storage tank, and everyone involved will breathe a collective sigh of relief. Weather permitting; the job of lifting will start tomorrow, beginning with a container filled with dozens of pails of hydraulic oil. If all goes well with this initial lift, the fuel truck will be hoisted to the surface the following day (Thursday) or perhaps a day later. On the surface at least, the plan is a sound one, though the operation is still complicated and unknowns may lie in the way. To guard against the possibility of an inadvertent spill of oil, booms will be deployed around the site. Everyone involved hopes they won’t be needed, and that the weather cooperates. We will let you know what happens once the salvage operation is completed. In the meanwhile, our fingers are crossed.

Grey Whale - Ship Strikes
Preliminary findings were that the 41.5' adult male
Gray whale had good body condition and had a stomach full of food (ghost shrimp and other inverebrates from a quick glance). Evidence of bruising and internal bleeding lead biologists to believe this whale likely died from blunt force trauma, such as a large ship strike.
Cascadia Research will be providing a summary of their findings on both this whale and the whale necropsied Tuesday near Birch Bay, WA which we will post in our next whale report.

Healthy Oceans
A credible, long-term plan for any ocean region must include an increase in protected areas where specific types of industrial activity are limited. Canada has the longest coastline of any nation on Earth, and 40 per cent of our jurisdictional area is ocean, yet the federal government has set aside less than one per cent of that as marine protected areas. - Dr. David Suzuki

Navy Submarine Sonar
This file is edited from the Navy SONAR recorded yesterday by John Boyd through the Whale Museum Lime Kiln hydrophone. The sonar had a fundamental frequency of 3.8Khz with harmonics up to 15Khz. The fundamental frequencies of killer whale calls range from 300Hz to 6 kHz. Killer whales respond to tones within the frequency range of about 0.5 to 125 kHz. Peak hearing sensitivity for killer whales is about 20 kHz and their sensitivity declines gradually above and below 20 kHz. Dr. Val Veirs of Beam Reach reported that the SONAR source level was in the range 175 dB to 225 dB re 1 microPa@1m.

Transient T44 found dead
John Ford of Canada's DFO reported the sad news that 31 year old male Transient T44 had been found dead near Port Hardy, BC. T44 and his family, the T41's have been sighted and reported regularly to Orca Network, and T44 was one of those easy to recognize whales with his large fin with a nick in it.
A couple of days ago, the MacKays were told of a sighting of a dead orca floating near Hope Island (near Port Hardy). The DFO was alerted and with the help of a Coast Guard boat, that was in the vicinity, the whale was secured. DFO was able to identify the 31 year old transient male as T44. A necropsy will be performed in the next day or so. Finding a whale, soon after death, is a very rare occurrence and presents an opportunity to gain valuable knowledge.

Killer Whale Protection
Feds boost protection for killer whales after being sued
The federal government is making it illegal to damage the habitat of critically endangered killer whales off the coast of B.C. — and a coalition of environmental groups is taking credit. The government issued an order under the Species at Risk Act this week that legally protects the areas where northeast Pacific northern and southern resident populations of killer whales live. It also enhances the government's ability conduct inspections and investigations and fine parties who damage those areas, although it does not include specifics about what would constitute damage. A coalition of environmental groups says a lawsuit they launched in October, which alleges the government failed to protect killer whales' habitat as required by law, prompted the government to issue the order on Monday. Jay Ritchlin, director of marine and freshwater conservation at the David Suzuki Foundation, one of the groups involved in the case, said he is glad the federal government has now decided to take this step. "And we're looking forward to a time when they do so without having to be sued first," he said in a statement. The order is the first ever made under the 2004 Species at Risk Act. It came after the government stated in September that it would rely on existing legislation to protect the killer whales. That prompted nine environmental groups represented by Lara Tessaro, a lawyer with the environmental law group Ecojustice Canada, to file the lawsuit against the government.
Review prompted order: official
Pardeep Ahluwalia, director general of the species at risk management program at the Department of Fisheries and Oceans, said government has reviewed the killer whale protection policy it issued in the fall, taking into account comments from stakeholders, including environmental groups. "We thought we could do better and so the protection order that we published this week was in response to our review," Ahluwalia said. "It's hard to say whether or not that [lawsuit] influenced our decision." Such reviews are standard when the government is working with new legislation such as the Species at Risk Act, he said. According to the Department of Fisheries and Oceans resident killer whale recovery team, the animals are threatened by declining salmon stocks, increased boat traffic, toxic contamination, and loud underwater noises from dredging. Recent counts show 85 individuals remain in the southern population and around 245 in the northern population.
The nine groups involved in the lawsuit are:
* Dogwood Initiative.
* Environmental Defence.
* David Suzuki Foundation.
* Raincoast Conservation Society.
* Sierra Club BC.
* International Fund for Animal Welfare.
* Greenpeace.
* Georgia Strait Alliance.
* Wilderness Committee.
Tessaro said Wednesday that while she is pleased with the government's order, she won't immediately drop the lawsuit. She wants to see the final, more detailed version of the order that is to be published in the Canada Gazette on March 4 and then consult with her clients before taking that step. "I'm quite sure that this lawsuit is what forced DFO to issue this order," she said. Environmental groups are now hoping the government is serious about enforcing the new protection for killer whales and will follow up with similar orders for other endangered species, Tessaro said. "What this means for the whales is that no longer is their survival and recovery going to be dependent on old laws like the Fisheries Act or unenforceable policies," she said. "Endangered species in Canada are endangered because their habitat is being degraded. Orders protecting their habitat are fundamental if we're going to ensure that these species survive and recover."

Faith - L57
Faith has been determined as missing by the Center for Whale Research. A recent CWR superpod encounter near Victoria revealed the 31 year old adult male missing and two new babies one in L and J pods each bringing the total for the population to 85 whales. This population is usually off Monteray Bay, CA, at this time of year. Faith is the last member of the L45 matriline. His mother L45 died in 1995 at the age of 57 years old. Faith was her only surviving offspring, his sibling L36 was born two years earlier but died later that same year in 1975. Faith's uncle died, at the age of 19, the same year L57 was born in 1977. The average life span for male resident killer whales is 29 years of age, but they can live longer. Ruffles is the oldest living male southern resident at 58 years of age.

Ocean Noise 2008 Science
Behavioral impacts clearly replaced strandings and deaths as the key issue for marine mammals encountering human noise. Several studies released during 2008 all suggest that whales of many species may stop or reduce their feeding when moderate to loud human sounds enter their habitat, and this particular impact is likely to become a central focus of future research and regulatory consideration.
The legal tussles over mid-frequency and low-frequency active sonars continued, and the Supreme Court decision does not put an end to the controversy. The Navy crossed an important threshold, completing full Environmental Impact Statements for their sonar training procedures for the first time; the lack of sufficient NEPA analysis was the root of most of the legal challenges. The plans they are putting forward to govern sonar training off most of the US coastline continue to rely on safety measures that Federal Courts have found wanting, though it appears that challenges to their proposals are more likely to focus on avoiding biologically important areas than increasing the safety zones that are designed to avoid injury. All parties seem to be accepting that gross injury is rare to the point of being difficult to use as a lever to shift the balance of interests with the Navy’s national security imperative, but NGOs, many field researchers, and agency staff are all looking more closely at the behavioral impacts that take place at much longer ranges (up to several or even tens of kilometers). The next round of Navy sonar conflicts will center on how willing the Navy is to consider these subtler impacts, and whether NMFS or the courts will impose broader territorial restrictions on sonar training to protect areas where whales may be more susceptible to repeated disruption by sonar transmissions.
Shipping noise is moving very quickly to the forefront of international concerns about rising ocean noise. This year the US, with strong German support, initiated a two-year process at the International Maritime Organization to come up with ship quieting recommendations. Also, the unusual sensitivity of harbor porpoises to boat noise has become clearer.

Dolphins, whales lack protection from fishing
WASHINGTON (AP) — The Bush administration has failed to provide protections required by law to more than a dozen marine mammals potentially at risk of death or injury due to commercial fishing, congressional investigators said Wednesday.
The report by the Government Accountability Office assessed the National Marine Fisheries Service, which identifies potentially endangered animals such as whales and dolphins that can become entangled in fishing gear or lobster traps. It found that out of 30 marine mammals deserving protection under federal guidelines, the agency had failed to set up teams of experts to provide protection for 14 of them.
According to the GAO, the fisheries service was generally aware it needed to take protective measures for the additional mammals, which included the Hawaiian stock of false killer whales and the Central North Pacific stock of humpback whales. But it had not done so because officials said they either had faulty data and lacked money to obtain better information, or believed factors other than commercial fishing were to blame.
The GAO also said the fisheries service generally lacked a "comprehensive strategy" for assessing the effectiveness of its animal protection measures and often missed deadlines to set up teams and devise safety plans.
The report urged Congress to have the fisheries service report on any data limitations. Lawmakers should also consider steps to ensure the agency complies with federal law, it said.
The fisheries service "faces a very large, complex and difficult task in trying to protect marine mammals from incidental mortality and serious injury during the course of commercial fishing operations," investigators wrote.
The GAO report comes a day after President George W. Bush designated what he called "three beautiful and biologically diverse areas of the Pacific Ocean" as national marine monuments in what was the largest marine conservation effort in history. Bush used his announcement to broadly defend his environmental record.
"For an administration that is desperately trying to create a legacy of ocean stewardship before leaving office, it is disappointing to hear that they have dropped the ball on reducing incidental deaths of mammals due to commercial fishing," said Rep. Nick J. Rahall, D-W.Va. He is chairman of the House Natural Resources Committee, which requested the GAO report.
