By Anne-Sophie Fortin August 14, 2022 As we transit toward the next station with a speed of about 8 knots, we are taking continuous profiles of the upper 100 meters of the ocean. To do so we use a Moving Vessel Profiler (MVP), an instrument measuring temperature and conductivity (from which salinity can be derived) […]
Throwing Scientific Instruments Overboard
By Anne-Sophie Fortin August 13, 2022 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 […]

Surfactants are ubiquitous!
***deutsche Version siehe weiter unten*** Teaser: Scientists are concerned about surface active compounds (known as surfactants) in any air-sea exchange processes nowadays. During our ongoing research in the Baltic Sea, scientists from IOW and GEOMAR came together on RV EMB295 to address the question of how surfactants in surface seawater of the Baltic Sea control […]
A scientific identity crisis – My first year as a doctoral candidate
