english version below Die biologische Ozeanographin Helena Hauss und die Ozeanographie-Studentin Anna-Christina Hans erzählen hier von ihrer spannenden Forschung an Strömungswirbeln im Östlichen Atlantik Eines der Ziele unserer Forschungsreise ist, die Rolle von Wirbeln (oder „Eddies“) für das pelagische Ökosystem der Kapverden besser zu verstehen. Wirbel sind rotierende Wasserkörper im Ozean von meist etwa fünfzig […]
[deutsche Version unten] by Stella Scheer and Veronique Merten The PhD students Stella Scheer and Veronique Merten of the Deep-Sea Biology Working Group at GEOMAR are reporting here about a method to trace marine animals without observing the animals During our cruise we sampled five different locations for environmental DNA (eDNA), including in- and offshore […]
(Deutsche Version unten) by Rui Freitas, 22-Feb-2019 Rui Freitas is a marine biologist and lecturer at the University of the Cape Verde. Here he reports about his two dives with the manned submersible JAGO down to the steep slopes of Santo Antão and Fogo. The deeper slopes of the Cape Verde islands have never been […]
english version below …braucht Zeit und die richtigen Bedingungen! Hier erzählt JAGO-Pilot Peter Striewski von seinem Weg ins „JAGO-Cockpit“ Wer den eng getakteten Forschungsbetrieb auf Ausfahrten mit einem Forschungsschiff kennt, weiß, dass es gar nicht so einfach ist, Zeit zum Üben eines reibungslosen Einsatzes von mitgebrachten Geräten und – wie in unserem Fall – Fahrzeugen […]
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 […]
(Deutsche Version unten) Between the 14 Feb and 1 May 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: Karen Osborn, Curator of Marine Invertebrates at […]
(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, […]
