The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.

The system could be used for battery-free underwater communication across kilometer-scale distances, to aid monitoring of climate and coastal change.

The color changes reflect significant shifts in essential marine ecosystems.

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.

A new method for removing the greenhouse gas from the ocean could be far more efficient than existing systems for removing it from the air.

Prochlorococcus, the world’s most abundant photosynthetic organism, reveals a gene-transfer mechanism that may be key to its abundance and diversity.

Up to one-third of the carbon consumed by Prochlorococcus may come from sources other than photosynthesis.

Swirling waters replenish nutrients in open ocean, a new study finds, and could mitigate some climate change effects.

The device could help scientists explore unknown regions of the ocean, track pollution, or monitor the effects of climate change.
