Today we (purposely) throw some scientific instruments overboard, the firsts of many. In the picture, you may see Paula lowering a Hereon Drifter with a rope. A Hereon Drifter is a Lagrangian surface drifter, which means that it follows the water mass where it has been deployed, under the condition that the water mass in question stays in the upper part of the ocean as the Hereon Drifter float at the surface. It is quite useful to estimate upper water currents as the instrument report its position every 5 minutes.
