An expedition can never be fully planned in advance. At sea, everything can evolve differently every day, every hour. So was the case for this trip. The drifter, which was supposed to be followed until the 7th of February, left the upwelling patch and was heading at high speed to the south. As a result, […]
The week is starting onboard POSEIDON. Slowly the sun rises, immersing the sea for a brief moment in orange-red light. Eight o’clock. The work on the deck and in the laboratories is going on. The day begins with the measurement of the microstructure sonde, followed by the CTD. In addition to this station work, so-called […]
A focus of this trip is on the drifter, which tracks the course of an upwelled water patch of deep water. After we deployed the drifter on January 27, we followed it for several days. We also surveyed the area around the drifter by doing east-west and north-south sections, always returning to the drifter. On […]
Three times a day, water samples are taken on the R/V POSEIDON using the CTD rosette. CTD stands for conductivity, temperature, and depth, which is determined by measuring the pressure. CTD sampling provides a vertical profile of the water and brings water from different depths to the surface. The CTD rosette on board consists of […]
Saturday, the 27th of January 2018. Today we finally launched the drifter. In the last days we searched for a suitable upwelling-patch off the coast of Mauritania. The drifter has been prepared until late in the night. In the morning, we came closer to the final point of deployment, an area with a fresh upwelling-patch, […]
In the early morning of the 23th of January 2018 the R/V POEIDON left Las Palmas and sailed in the following two days to the coast of Mauritania. During the transit the scientists set up their labs, took initial test measurements and checked the functionality of all their equipment for the upcoming research. Using satellite […]
Las Palmas. Yesterday we started the setup for the upcoming expedition on board the POSEIDON. Almost all of the equipment arrived with the ship in a container, which had to be emptied upon arrival. With all equipment on deck, the setup in the different labs and on deck could start. Melf installed a mast on […]
It`s the first weekend of the year 2018 and the scientific crew of the research cruise POS519, from Las Palmas to Mindelo, is lifting the container with the equipment on board the POSEIDON, which is currently docked in Kiel. The drifter has been safely stored in the wet lab, the boxes with the material for […]
After a year of planning and organizing we come closer to the final date of departure for the research expedition POS519. While everybody is packing gifts for Christmas, we are packing our container which will go on board the R/V POSEIDON on January 2018 heading to Las Palmas. In Las Palmas we will start our […]
