🌊 Marine heatwaves and the carbon cycle

A new study shows that marine heatwaves can disrupt food webs and carbon transport in the NE Pacific.

Marine heatwaves modulate food webs and carbon transport processes - Nature Communications
A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.
