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.

Scientists bring marine plankton back to life to study past climate change.

Former NOAA administrator and environmental scientist Jane Lunchenco discusses the importance of science in the face of climate change.

Data collected by elephant seals in Antarctic waters provide a closer look at the processes driving ocean circulation.

Irish researchers convert seals into remote oceanographic sensors by attaching tags containing temperature probes and other technologies to their heads.
