A new study by USA’s National Oceanic and Atmospheric Administration (NOAA) discovered heat waves at the bottom of oceans that are affecting marine life. Researchers have been studying marine heat waves at the ocean’s surface for more than 10 years but have assessed the bottom of the ocean for the first time using a data product called ‘reanalysis’. The study reveals that marine heat waves last for a longer duration than surface heat waves and vary in intensity, ranging from 0.5˚C to 3˚C above normal temperatures. The ocean absorbs approximately 90% of the extra heat from global warming and has warmed by around 1.5˚C over the last 100 years. The study of marine heat waves will help in creating a plan to protect marine species.

Marine heat waves cause the destruction of seagrass and coral bleaching, leading to a decline in the number of marine creatures.
