Drones confirm importance of Costa Rican waters for sea turtles
A new drone-enabled population survey – the first ever on sea turtles – shows that larger-than-anticipated numbers of turtles aggregate in waters off Costa Rica’s Ostional National Wildlife Refuge, making it one of the most important nesting beaches in the world. Scientists estimate turtle densities may reach up to 2,086 animals per square kilometer.
Rising temperatures turning major sea turtle population female

Already on Brink, Right Whales Are Pushed Closer to the Edge
North Atlantic right whales are one of the world’s most critically endangered large whales.

Marine turtles dying after becoming entangled in plastic rubbish
Hundreds of marine turtles die every year after becoming entangled in rubbish in the oceans and on beaches, including plastic ‘six pack’ holders and discarded fishing gear.
Can Data Save Dolphins? How Scientists Are Using NASA Data to Study Link Between Solar Storms and Animal Beachings
The age-old mystery of why otherwise healthy dolphins, whales and porpoises get stranded along coasts worldwide deepens: New research suggests space weather is not the primary cause of animal beachings — but the research continues. The collaboration is now seeking others to join their search for the factors that send ocean mammals off course, in the hopes of perhaps one day predicting strandings before they happen.
Soul-crushing’ video of starving polar bear exposes climate crisis, experts say
Video footage captured in Canada’s Arctic has offered a devastating look at the impact climate change is having on polar bears in the region…
