Ocean complexities: killer eddies and bigger typhoons

June 11, 2015

The warming of the Pacific over the last few decades suggests we might have fewer but more intense typhoons. And this is the first year since 1997 to have a significant El Niño.

Satellite data indicates the oceans are full of eddies that travel with the major currents, creating areas of oxygen depleted water, possibly hazardous to marine life. It’s certainly the case that you run into odd currents offshore, different from the major ones expected. Since these no doubt have been a feature of ocean ecology forever, it’s interesting to speculate how they might affect marine evolution. Still a lot of unknowns about this. Interesting. (Cite.)
