Microplastics are changing the gut microbiomes of wild seabirds. Humans should be wary, too, researchers say.

A new machine-learning model makes more accurate predictions about ocean currents, which could help with tracking plastic pollution and oil spills, and aid in search and rescue.

A new study shows the carbon-capturing phytoplankton colonized the ocean by rafting on particles of chitin.

Arctic sea ice algae contaminated with microplastics have serious consequences for ecosystems and the climate.

The tiny organisms that cause harmful blooms of algae can have a big impact on your trip to the shore. A toxicologist explains what causes these events and how to keep people and pets safe.

2023 "will be a very active hurricane season," says Xubin Zeng. "People should get prepared."

No place on Earth is free from pollution.

El Niño can trigger intense and widespread periods of extreme ocean warming known as marine heat waves. They can devastate marine life.

A new method monitors when deep sea methane deposits convert to gas and rise toward the seafloor in amounts that were previously too small to detect.
