"On land, we’re familiar with heatwaves and cold snaps. But the deep sea also
experiences prolonged periods of hot and cold.
Marine heatwaves and cold spells can severely damage ocean ecosystems and
habitats such as coral reefs. These extremes can also force species to move or
die and cause sudden losses for fisheries.
In research published today in
Nature, we show almost half of the heatwaves
and cold snaps reaching the ocean’s twilight zone – between 200 and 1,000
metres – are driven by large eddy currents, swirling currents which transport
warm or cold water.
As the oceans heat up, heatwaves linked to eddy currents are getting more
intense – and so are cold snaps. These pose potential threats to the vast
amount of life in the twilight zone, home to the world’s most abundant
vertebrate and the largest migration on the planet."
