A new study used the same kind of models that scientists use to track disease to instead examine how some California sea lions have learned to prey on salmon gathering to ascend fish ladders at Bonneville Dam.
Last year scientists combined infrared cameras with image recognition software to automatically detect and count migrating gray whales. This year, they upgraded.
The speed of vessels operating near endangered killer whales in Washington is the most influential factor — more so than vessel size — in how much noise from the boats reaches the whales.
Testing of samples from marine wildlife during an unprecedented harmful algal bloom on the West Coast in recent months detected indicate potentially widespread effects of the bloom in marine food webs.
Unmanned aerial vehicle allows scientists to study killer whale health and reproduction while also offering a glimpse into the family life of these social animals.
