Research led by the University of Oxford has found that oceanographic connectivity (the movement and exchange of water between different parts of the ocean) is a key influence for fish abundance ...

New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon ...

Ocean fish populations have fallen dramatically in the past half-century, and climate change is expected to make the problem worse. Governments have designated “marine protected areas”, where where ...

The open ocean’s twilight zone, a vast deep ecosystem rich in fish biomass, is poorly understood because it is expensive and challenging for humans to reach its depths 200–1000 meters (660–3,280 feet) ...

El Niño is back. By late fall 2026, forecast models give a 2-in-3 chance of a strong-to-very strong El Niño affecting the ...

On an unassuming morning off the Norwegian coast, millions of small fish called capelin began to gather in the ocean. Soon enough, they amassed to 23 million individuals, forming a group over 6 miles ...

Oceans absorb more than 90% of the excess heat caused by climate change. Oceans are hitting record high temperatures. The global average sea surface temperature hit an all-time record high of 69.73 ...
