Where have all the right whales gone?
(Fri, 12 Apr 2024)
Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to
commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine
spatial planning, and industry regulations to mitigate risk to right whales.

Entanglements of humpback whales in fish farms rare -- and naivety could be to blame
(Thu, 21 Mar 2024)
The first study of humpback whale entanglements in B.C. aquaculture facilities found eight over 13 years, with the curiosity of young whales a potential contributing factor.

Scientists weigh up current status of blue whale populations around the world
(Wed, 20 Mar 2024)
The largest living animal, the blue whale (Balaenoptera musculus) which averages about 27 meters in length, has slowly recovered from whaling only to face the rising challenges of global warming,
pollution, disrupted food sources, shipping, and other human threats. In a major new study, biologists have taken a stock of the number, distribution and genetic characteristics of blue whale
populations around the world and found the greatest differences among the eastern Pacific, Antarctic subspecies and pygmy subspecies of the eastern Indian and western Pacific.
