OSU team treks to Antarctica (48) Sep 2, 2008
These hydrophones, developed at the OSU center, will record the sounds of undersea earthquakes and volcanoes, moving ice sheets, and even the vocalizations from large baleen whales, according to Robert P. Dziak, an OSU associate professor who also works for the National Oceanic and Atmospheric Administration. This new ocean-sensor technology will use cold water-capable, deep-ocean hydrophones to provide the first-ever comprehensive record of the sounds of Antarctica, Dziak said.

Genome Of Marine Organism Tells Of Humans' Unicellular Ancestors Feb 20, 2008
According to King, biologists know almost nothing about these organisms, aside from the fact that they are an important food for krill, which are the main source of food for baleen whales, and that, by consuming large quantities of bacteria, choanoflagellates play a major role in the carbon cycle of the oceans. Yet, because choanoflagellates and animals shared a common ancestor between 600 million and a billion years ago, they hold a key to understanding the origins and evolution of animals. (Science Daily)
Humpback Whales Feb 19, 2008
Humpbacks are Baleen Whales, which means that they have sieve-like structures in their mouth instead of teeth, but unlike the they have pleated throats , making them Rorquals along with other filter-feeders such as the Blue Whale. Unlike other rorquals Humpbacks feed primarily on fish (most of the others prefer plankton). (Suite101.com)
The Inuit cultural matrix reloaded Feb 15, 2008
Dawson and a team visited the Thule native site on Bathurst Island in Nunavut, where they mapped out 23 whalebone houses that were constructed an estimated 600 to 800 years ago out of the remains of baleen whales, known as bowheads. But because the building material was so unusual, they employed laser scanning technology to capture 3-D pictures of a North Atlantic right whale skeleton that was on display at a Boston museum.

Migrating squid drove evolution of sonar in whales and dolphins, researchers argue Sep 6, 2007
" Lindberg and coauthor Nick Pyenson, a graduate student in the UC Berkeley Department of Integrative Biology and at the Museum of Paleontology, reconstructed this scenario after looking at both whale evolution and the evolution of cephalopods like squid and nautiloids - relatives of today's chambered nautilus - and relating this to the biology of living whales and cephalopods. All toothed whales, or odontocetes, echolocate. The baleen whales, which sieve krill from the ocean and have no teeth,... (EurekAlert!)

Whaling may have altered penguins' diet Jul 11, 2007
The near-extinction of Antarctic and sub-Antarctic fur seals during the 19th century, followed by the killing of baleen whales during the 20th century is thought by some researchers to have boosted krill populations in the Southern Ocean by more than 150 million tonnes. The scientists suggest that the Adlie penguins may have benefited from this and switched to eating krill. (New Scientist (subscription))
