What happens to marine life when oxygen is scarce?

A new study co-led by WHOI postdoctoral scholar Maggie Johnson looks closely at the changes occurring in both coral reef and microbial communities near Bocas del Toro during sudden hypoxic events, which occur when there is little to no oxygen in a given area of water.

Some Forams Could Thrive with Climate Change, Metabolism Study Finds

Oceanic deoxygenation is increasingly affecting marine ecosystems. A new paper that examines two foram species found that they demonstrated great metabolic versatility to flourish in hypoxic and anoxic sediments where there is little or no dissolved oxygen, inferring that the forams’ contribution to the marine ecosystem will increase with the expansion of oxygen-depleted habitats.

Pioneering Deep-Sea Robot Lost at Sea

A pioneering deep-sea exploration robot—one of the first successful submersible vehicles that was both unmanned and untethered to surface ships—was lost at sea Friday, March 5, on a research expedition […]

In CO2-rich Environment, Some Ocean Dwellers Increase Shell Production

In a striking finding that raises new questions about carbon dioxide?s (CO2) impact on marine life, Woods Hole Oceanographic Institution (WHOI) scientists report that some shell-building creatures?such as crabs, shrimp and lobsters?unexpectedly build more shell when exposed to ocean acidification caused by elevated levels of atmospheric carbon dioxide (CO2).
