Heat Waves, More Than Coral Death, May Cause Fish to Flee Reefs

Ilima Loomis, Science Writer by Ilima Loomis 25 July 201815 November 2022

A study over a broad swath of the Great Barrier Reef shows that warming waters directly cause fish and invertebrates to leave the reef, making it harder for coral to recover from bleaching events.

Upper Estuaries Found to Be Significant Blue Carbon Sink

Aaron Sidder, freelance science writer by Aaron Sidder 29 June 201826 March 2024

Inland from the seagrass and salt marsh ecosystems that border the ocean, upper estuaries store more carbon than previously realized and could play an important role in mitigating climate change.
