heatwaves have been taking an ever-greater toll on the world’s oceans and their ecosystems. Amplified by increasing global warming, these events are occurring more frequently and lasting longer. The Arctic is not spared from this trend either, as it is warming faster than any other region on our planet. However, due to local processes and conditions, marine heatwaves in the Arctic differ fundamentally from those in non-polar oceans.
