Deep Ocean Heat Waves Impact Carbon Storage.

NOAA researchers have identified marine heat waves at the bottom of the ocean, which can have larger warming signals than surface waters and persist longer. These events can occur simultaneously with surface marine heat waves, but can also occur with little or no evidence of warming at the surface, which has important implications for the management of commercially important fisheries. The authors say it will be important to maintain existing continental shelf monitoring systems and to develop new real-time monitoring capabilities to alert marine resource managers to bottom warming conditions.
