About this episode

This episode explores the science behind the Gulf's Loop Current and its significance in understanding ocean currents.

The amazing science behind understanding mysterious but critical ocean currents. And specifically, understanding the current in our backyard, the Gulf’s Loop Current. We talk with scientists leading a huge multi-country research collaboration that is going to great lengths and depths to understand the especially unknown Loop Current. We talk about how currents connect us, how they are basically a thermostat for the globe, and why, more than ever before, we need to understand them.
