Corals Are Simplistic When Conditions Are Acidic

by Anupama Chandrasekaran 16 August 202416 August 2024

Increasing ocean acidity could spell trouble for fish that depend on corals’ many branches for protection.

In Hot Water and Beyond: Marine Extremes Escalate

Sarah Stanley, Science Writer by Sarah Stanley 28 June 202428 June 2024

A new study suggests marine life is increasingly faced with triple-threat events in which extreme water temperature, low oxygen levels, and acidification converge.

Compound Extreme Events Threaten Marine Ecosystems

by Eileen Hofmann 23 January 202419 January 2024

Short-term extreme marine heat wave events superimposed on stressors from longer-term climate change produce compound extreme events that impact the Gulf of Alaska ecosystem.
