Team Geodesy

Today, we, the second smallest team of expedition M178, would like to introduce our mission on this cruise. ‘Team Geodesy’ is Morelia, Florian, and Christian and we are here to service a seafloor geodetic network that measures deformation of the submarine part of Etna’s mobile flank. On land, ground deformation is usually done using GNSS […]

Multibeam System in Betrieb genommen

Gestern wurde das Multibeam System in Betrieb genommen und der Sea Acceptance Test zur Kalibrierung des Systems gestartet. Währenddessen konnten wir den einen oder anderen Blick auf die Liparischen Inseln werfen, eine Inselgruppe im Tyrrhenischen Meer nördlich von Sizilien. Zu dieser Inselgruppe zählt unteranderem der Vulkan Stromboli, welcher in guter Sichtweite zu unserem Schiff lag […]

Inside the labs

Usually on research cruises, scientists from different areas come together and join their forces. Each field requires labs with different tools and specific demands to work in. Talking about labs creates a picture of people in white coats and safety goggles handling dangerous fluids. However, only one of our labs is a real chemical lab. […]

70 out of 30

With the amount of scientist limited due to corona restrictions the work that can be done is also limited. Also, we had just 16 working days in the Labrador Sea despite being 5 weeks on board. These circumstances led to the prediction of just conducting 30 to maybe 40 CTDs during this cruise. At least […]

Mooring works (2/2)

Recovering the 2 years old mooring is of course just one part of servicing the mooring. After getting back all the instruments, we need to conduct a calibration with each instrument. Therefor they get attached to a CTD to check whether they are still measuring accurately or show some drift. This calibration cast are mostly […]

Mooring works (1/2)

We left St Johns some days ago after a short stop of just a couple of hours. Heading towards the Labrador Sea preparing for the work to come. During the last days our focus was on the mooring array at 53°N consisting of 7 mooring. First, what is a mooring? In very simple words it’s […]
