How is one giant research vessel managed? Well, like any ship of this size, you will find the answer on what’s called the bridge. No worries, we are not trying to connect different ships between each other. That is just the main working station from which the ship is navigated. A little bit like the […]
Hello from Bornholm Basin in the central Baltic Sea! With a team of 12 scientists and 11 permanent crew, we are currently operating in Baltic waters with research vessel Alkor to improve understanding of this beautiful but also heavily impacted and rapidly changing system. For this purpose, we measure physical and chemical parameters (temperature, salinity […]
+++english version below+++ Nachdem das erste 2D-Profil nun abgefahren und die Ozeanbodenseismometer (OBS) und Hydrophone (OBH) wieder an Deck eingeholt waren, fuhren wir in das Gebiet für das zweite Experiment. Bei einem Profil werden Geräte in einer geraden Linie auf dem Meeresboden ausgesetzt. Anschließend wird das Profil mit Luftpulsern einmal abgefahren und die Signale werden […]
+++ english version below +++ Nun ist es schon über zwei Wochen her, dass wir uns in Kiel auf den Weg zur FS SONNE gemacht haben. Bis auf ein paar Kleinigkeiten, wie ein verspäteter Abflug von Hamburg aus, hat alles sehr gut geklappt und nach 31 Stunden waren wir am Hotel in der Stadt Concepción […]
By Anne-Sophie Fortin Every day aboard starts with looking up the weather forecast from our favourite meteorologist aboard: Julia Wenzel. Her forecasts are central to the planning of our day-to-day operations on the ship. While on land we may be more interested in whether a day will be sunny or rainy, here at sea we […]
This week, we recovered, serviced, and redeployed the last mooring of our cruise, the K1 mooring. This mooring measured continuously temperature and salinity in the central Labrador Sea since the early 1990s. More recently, oxygen sensors have been added to the uppermost part of the mooring. Measuring oxygen in the central Labrador Sea is quite […]

By Anne-Sophie Fortin As we transit at full speed (10 knots) in the Labrador Sea, we used the underway CTD (uCTD) to investigate the vertical structure of potential eddies identified from satellite imagery. The uCTD is a good compromise between research time, efforts, and the dataset we get from it. Indeed, the ability to get […]
By Anne-Sophie Fortin August 24-26, 2022 If the marine life would have weather forecasts, they would have eddies maps. Eddies are circular currents of tens to hundreds of kilometers in diameter and a lifetime of about a month. They can be seen on satellite imagery as minimums and maximums of sea surface heights and sea […]
By Anne-Sophie Fortin Over the past 20 years, Argo floats have caused a small revolution in the field of observational oceanography as they provide near real-time measurements of the ocean subsurface, which have greatly improved our weather forecast and ocean analysis. Currently, there are ~4,000 floats sampling the oceans year-round. These floats are autonomous underwater […]
