What Do Killer Whales Eat In The Arctic?
2012-01-30 09:36:54

Killer whales (Orcinus orca) are the top marine predator, wherever they are found, and seem to eat everything from schools of small fish to large baleen whales, over twice their own size. The increase in hunting territories available to killer whales in the Arctic due to climate change and melting sea ice could seriously affect the marine ecosystem balance. New research published in BioMed Central's re-launched open access journal Aquatic Biosystems has combined scientific observations with...

Beluga Whales Trapped By Ice In Russia

More than a hundred Beluga whales are trapped in frigid water surrounded by ice floes in the Chukotka region of Russia´s Far East, and risk death unless they are rescued soon, local authorities said. The flock of gentle whales was trapped in the Sinyavinsky Strait off the Bering Sea near the village of Yanrakynnot, a statement from the Chukotka Autonomous Region said, with local governor Roman Kopin calling for the government to send an icebreaker to the region to try and free them...

Proof-of-Concept Study Published in Journal of Geophysical Research-Oceans In a research paper published online Saturday in the Journal of Geophysical Research Oceans, a publication of the American Geological Union (AGU), scientists reported the southern Baffin Bay off West Greenland has continued warming since wintertime ocean temperatures were last effectively measured there in the early 2000s. Temperatures in the study were collected by narwhals, medium-sized toothed Arctic whales, during...

New aerial survey techniques lead to increased narwhal estimates Improvements in aerial survey methods have led to increased estimates of narwhal populations in the eastern Arctic, according to a paper published Arctic, the journal of the University of Calgary's Arctic Institute of North America. Previous estimates of narwhals were based on surface counts and covered part of their eastern Arctic summering range. They placed populations between 20,000 and 30,000. New estimates increase that...

The World Conservation Society in New York says while cancer touches the lives of many humans, it is also a major threat to wild animal populations. Cancer is one of the leading health concerns for humans, accounting for more than 10 percent of human deaths, said Dr. Denise McAloose, the WCS study's lead author and chief pathologist for its Global Health Program. But we now understand that cancer can kill wild animals at similar rates. The scientists said cancer is threatening the survival of...

Scientists say they've found a much higher level of mercury flowing from Canada's Mackenzie River into the Arctic Ocean than found by previous studies. University of Alberta researcher Jennifer Graydon and her colleagues analyzed water in the Mackenzie River as it flowed north into the Beaufort Sea. She collected samples for three months and discovered the total amount of mercury exported from the river during that period was equal to an entire year's worth of mercury calculated in previous...

University of Alberta researchers conducting a water study in the Mackenzie River Delta have found a dramatically higher delivery of mercury from the Mackenzie River to the Arctic Ocean than determined in previous studies.Researcher Jennifer Graydon analyzed water in the Mackenzie River as it flowed north into the Beaufort Sea. She collected samples for three months and discovered the total amount of mercury exported from the river during that three-month period was equal to an entire year's...

Alaska's government said Wednesday it plans to issue a challenge to block federal protections for a struggling population of beluga whales in Cook Inlet, a mature oil-producing basin. The decision comes just five months after suing to keep polar bears off the U.S. threatened species list. The energy-rich state believes the Endangered Species Act protections for belugas announced in October by the National Oceanic and Atmospheric Administration (NOAA) are unwarranted, according to former vice...

Federal researchers said they're trying to figure out why beluga whales are dying in Alaska's Cook Inlet. The belugas have been listed as endangered, with an estimated 375 of the animals left in the area. A report by the National Marine Fisheries Service suggests 18 possible threats to the whales, including disease, whale poaching and unnatural noise in the water from off-shore drilling and pile-driving, the Anchorage Daily News reported Wednesday. Researchers said oil and gas spills,...

The federal government listed Alaska's beluga whales as endangered on Friday, after the National Oceanic and Atmospheric Administration (NOAA) determined that belugas in Cook Inlet are at risk of extinction and deserving of protection under the Endangered Species Act.Whales in the Cook Inlet, the channel that flows from Anchorage to the Gulf of Alaska, are among five beluga populations in Alaska waters.Alaska Gov. Sarah Palin called the move "premature", and pressed for more time to make...

The Beluga Whale or White Whale (Delphinapterus leucas), is an Arctic and sub-arctic species of marine mammal. It is commonly referred to simply as the Beluga. The Beluga occurs in waters from 50° N to 80° N. There is also an isolated population which travels the St. Lawrence River estuary and the Saguenay Fjord. There is an endangered colony of Belugas in the Cook Inlet in Alaska as well. This small whale can grow up to 16 feet long and is larger than most dolphins, but smaller...
