Researchers use proxy indicators to confirm long-term changes to the Atlantic Meridional Overturning Circulation, which have profound implications for future climate in North America and Europe.

By analyzing how fin whale calls bounce off the seafloor, scientists can recreate ocean crust layers.

Overfishing is the biggest factor driving these species toward extinction, researchers conclude from a new study.

Blue sharks don't dive as deeply in low-oxygen waters—which become more prevalent as oceans warm—effectively pushing them into areas of high fishing pressure.

Lore has always surrounded argonauts, pelagic octopuses that build shells and travel the seas.

The discovery puts a nail in the coffin of a long-held assumption about the limits of where the essential process can occur.

The retired University of California, Santa Cruz, professor was known for his work on invertebrate reproduction, kelp ecology, and Antarctic marine life.

The newly described Ikaria wariootia was a small, wormlike creature that marked an important evolutionary step between early multicellular organisms and more complex modern animals.

Preserved DNA extracted from the rock-like digestive blobs may offer insights into whale ecology.
