A new study published in the Journal of Physical Oceanography suggests that rising temperatures in the arctic could result in warmer water with density more affected by temperature than salinity.

Each summer, millions of fish return to Bristol Bay and then swim on to the stream where they were born to spawn, and die. Exactly what compels them to return to the right spot is unknown, but scientists think that some hatchery-raised steelhead in Oregon might hold a clue.

In the next 50 years, there’s a 9 percent chance of an Aleutian Islands earthquake so strong it could send a devastating tsunami to Hawaii.

The Cook Inlet Beluga Ecosystem Portal is a one-stop shop for beluga data that its creators hope will help scientists and the public make more informed decisions in the future.

This is how ice leaves our planet.
