Drilling for minerals deep in the ocean could have immense consequences for the tiny animals at the core of the vast marine food web — and ultimately affect fisheries and the food we find on our ...

The deep, blue sea is becoming deeper — in color, that is. Climate change, along with human development, has reduced how much light can filter through the water. Reduced light can significantly ...

Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that ...

The overheating of the Indian Ocean to potentially lethal levels due to marine heat waves and sea surface temperature increase poses severe challenges.

The shrinking sea ice in the Arctic Ocean is, overall, a disaster. But paradoxically, the melting of the ice can also fuel the engine of the Arctic food chains: algae. Algae are the main food source ...

A marine heat wave is warming California’s coast, driving seabird starvation, ecosystem stress and record ocean temperatures.

California marine heat wave drives seabird die-offs and marine mammal stress as ocean temperatures spike off West Coast. Will ...
