Unprecedented Dive Uncovers Troubling Secrets of the Ocean's Depths

A study led by researchers from the National Oceanic and Atmospheric Administration (NOAA) has revealed that marine heat waves also occur at the seafloor, with deep sea heat waves lasting longer than those at the surface. These heat waves can have devastating effects on ocean ecosystems, disrupting the behaviors and productivity of marine life. The study highlights the need for early recognition and proactive management of marine heat waves, particularly at the ocean bottom where valuable species reside. The frequency of marine heat waves has increased by 50% in the past decade, largely due to the oceans absorbing excess heat from global warming.
