Story summary

The study published October 6 in Nature Communications finds marine heatwaves disrupt ocean food webs and slow carbon transport to the deep sea.
Researchers observed two major Northeast Pacific heatwaves and found plankton changes that altered carbon cycling.
In 2023, unprecedented heatwaves affected 96% of the world's oceans and caused coral bleaching and disrupted fish populations.
The findings underscore the urgent need for coordinated ocean monitoring to understand and mitigate impacts.
