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

Marine ecologist Jeroen Ingels discusses what is known about ice shelf loss at the southern pole and how those changes are affecting local ecosystems.

Unable to travel to international or remote sites, some researchers are losing critical data.

Jellyfish fitted with energy efficient controllers could one day find a job on ocean explorations.

The movements of water within the ocean basins has been increasing in speed over the last 20 years, a new study shows, conflicting with prior models of climate change.

Biological production of this greenhouse gas, once thought to be the reserve of anaerobic microbes, occurs in these widespread, photosynthesizing cyanobacteria.

Microbes that dwell in nutrient-poor waters use a photopigment called retinal to harvest energy from sunshine at levels at least equal to those stored by chlorophyll-based systems.

Birds drifting on the surface of the sea could provide valuable data for oceanographers.

The Challenger expedition's data on ocean temperatures and currents, seawater chemistry, life in the deep sea, and the geology of the seafloor spurred the rise of modern oceanography.
