Heatwaves underwater?

We all experience heat waves on land, like the one that occurred not long ago at the start of autumn. But did you know that heat waves also happen underwater, at depth?

Researchers recently published a study of temperatures recorded at the bottom of the ocean around North America and found extreme warming along the seafloor can have significant biological outcomes. The intensity and duration of bottom marine heatwaves (BMHW) vary strongly with depth, and can be more intense and last longer than marine heatwaves at the ocean surface (SMHW).
