New information may help with recovery efforts for endangered Cook Inlet belugas. When listening to beluga whales, the sound of a crunch or a clapped jaw may be a reliable indication that a beluga whale just successfully captured or missed a fish. In a new published paper on beluga whales in Alaska, scientists analyzed sound data, collected […]
NEWPORT, Ore. – Researchers can now determine the age and sex of living beluga whales in Alaska’s Cook Inlet thanks to a new DNA-based technique that uses information from small samples of skin tissue. Accurate age estimates are vital to conservation efforts for Cook Inlet belugas, which were listed as endangered following a significant population decline in […]
Bowhead whales are true northern creatures, swimming only in cold oceans off Alaska, Canada, Greenland, Svalbard and Russia. These bus-size whales have the largest mouths in the animal kingdom, can live for 200 years and can go without eating for more than a year due to their remarkable fat reserves. Bowheads are also a rare […]
A new study provides essential information to conserve an endangered species and supports subsistence communities own observations. For the first time, scientists have direct evidence that killer whales are preying on bowhead whales in the U.S. Pacific Arctic. A dramatic loss of sea ice in recent years may be leaving bowheads more vulnerable to […]
The impacts of predator loss and climate change are combining to devastate living reefs that have defined Alaskan kelp forests for centuries, according to new research published in Science. “We discovered that massive limestone reefs built by algae underpin the Aleutian Islands’ kelp forest ecosystem,” said Douglas Rasher, a senior research scientist at Bigelow Laboratory for […]
Research aims for baseline information on whale behavior and biology in absence of vessels. This is a collaborative effort with the University of Alaska Southeast, University of Alaska Fairbanks, NOAA Fisheries Alaska Regional Office and Alaska Fisheries Science Center/Auke Bay Laboratories and the Pacific States Marine Fisheries Commission. It’s an unusual year out on […]
Scientists partnered with tech industry experts to develop the first machine learning application for acoustic monitoring of Alaskan beluga whales. An innovative machine learning application will help scientists collect information essential to protect and recover the endangered Cook Inlet beluga whale population. In 1979, the Cook Inlet beluga population began a rapid decline. Despite being protected as an […]
Highly-trained responders depend on boating community to be “eyes and ears” on the water
Photograph of fin whale taken during Oregon State University Marine Mammal Institute CORVALLIS, Ore. – Researchers using electronic tags were able to monitor blue and fin whales off the coast of Southern California over multiple weeks, providing new insight into the feeding behaviors of the two largest whale species. The researchers also found evidence of […]
