Great News at the Ocean Summit in Hong Kong as the second Team (AkzoNobel) will jump into the Oceans with our Equipment from Leg 7 onwards next to Turn the Tide on Plastic. My talk did cost me my lunch that day as there were so many interested people in our research activities and possible […]
Bottlenecks – part II (read part I here) In our final blog we will re-capture our journey through the Mediterranean as it is not very often that one gets to travel from one end almost to the other. The Mediterranean is unique because of its numerous passages and straits. These maritime bottlenecks also characterized our […]
Oceanographic pioneer Maurice Ewing is reported to have advised his students that the key to discovery is to take a new instrument to a place where no one has explored before. The midwater research conducted off the Cape Verde Islands during Poseidon Cruise 520 is a fine example of that research philosophy. The unique combination […]
by Nuno Vieira (INDP) During POS520 I help my German colleagues to collect environmental data with a CTD and water sampler rosette. I filter seawater samples taken in different depths to determine its oxygen content, and I assist in operating the Microstructure Probe which is used to profile the vertical current structure of the ocean. […]
(Deutsche Version unten) Our cruise on the RV POSEIDON slowly comes to an end and today is the last day of sampling. My task during this cruise is sampling environmental DNA (eDNA). eDNA is defined as genetic material obtained directly from environmental samples, in our case water samples of different depths, without any obvious signs […]
(Deutsche Version unten) Finally, we have JAGO back on board the FS POSEIDON once again, and this time in an even warmer working area. We gladly left the gray winter in Kiel behind for this cruise. Every time we pull the yellow submersible out of the transport container on the deck of POSEIDON, it’s like […]
During our last days here in our working area we are shifting it into gear, because it is harvesting time! Finally we will have a look at our data coming back from the sea floor – we all have been waiting for this very moment since weeks now (and some of us since a few […]
In our last blog entries we have already reported on our gear and how difficult recovery can be at times. Today, we would like to share some of the daily working life of the scientists here on board with you. Marine geophysical surveys commonly require a large number of helping hands (and brains, of course). […]
(Deutsche Version unten) Between the 14 Feb and 1 March 2018 expedition POS520 with RV POSEIDON and the submersible JAGO takes place off the coast of the cape verde island Santo Antão. The chief scientist, the JAGO team and participants of the cruise write here as guest writers. Today Henk-Jan Hoving, GEOMAR, Deep Sea Biologist, […]
If you want to get an image of the Alps, you need seismometers surrounding the area. But how do you get the seismometers to work at the bottom of the sea? And how do you get them back? To explain this, we invite you to a virtual journey on board of the research vessel Maria […]
