Glider Recovery in a Zodiac

By Anne-Sophie Fortin After one week of measurements, the glider was successfully recovered today. As it is a somewhat delicate instrument, some of us took a zodiac to bring it back to the ship. The member of the expedition had to wear a survival suit in case someone would have fallen into the cold water […]

Release of SAMS Pressure Sensor

By Anne-Sophie Fortin Today we deployed a highly sensitive bottom pressure instrument from the Scottish Association of Marine Science (SAMS) that will takes measurements for the next 10 years. This instrument is one of a set of two designed to measure the sea surface height across the North Atlantic. The difference in sea surface heights […]

Maintenance of the 53N Array

By Anne-Sophie Fortin Lately, our work is mostly about the maintenance of the moored instruments of the 53oN array that are near the Labrador Shelf. The maintenance of the 53oN array consists of recovering and cleaning the moorings, refurbishing or replacing the instruments and calibrate them, and finally, deploying the mooring at the same location. […]

Mooring Deployment

By Anne-Sophie Fortin After mooring recovery, maintenance, and calibration it is now time for mooring deployment. The moored instruments are fixed in intervals on a very long cable as we want to measure water mass fluxes from the surface to the ocean floor. Thus, to deploy a mooring, we need to steam slowly as we […]

Surface to the Ocean Floor Survey with the CTD-Rosette

By Anne-Sophie Fortin As we move along the 53oN Array, we are performing “CTD casts” which consist of lowering a CTD-Rosette to the ocean floor and pulling it back up on deck. A CTD is an instrument that precisely measures the Conductivity and Temperature at every Depth. We can then compute the salinity from the […]

Polar Lights, Red Moon, and Shooting Stars

By Anne-Sophie Fortin Nature showed its artistic talents today. After a few days in the fog, we finally had a clear sky. As the sunset painted the sky and the water in warm colours, a red half-moon rose slowly at the horizon. Gradually, the milky way illuminated the sky along with some shooting stars. All […]

Glider Deployment

By Anne-Sophie Fortin August 16, 2022 After the successful calibrations performed yesterday, one of the two Gliders has been deployed today. It will be autonomous and take measurements of water properties, such as temperature, salinity, oxygen, and chlorophyll until its recovery a few days from now. Koordinaten: 52.80255, -51.597367

The cruise is coming to an end, and there are 8 days left until we enter the port of Guayaquil. While some of the measurements on board can be read out directly and preliminary interpretations are presented during the cruise, there are also a lot of samples that can only be analyzed in the laboratory […]
