(English below) In meinem ersten Beitrag zur gerade stattfindenen Wirbeljagd im tropischen Atlantik habe ich von mehreren autonomen Geräten gesprochen, die schon vor der Schiffskampagne vor den Kapverdischen Inseln im Einsatz waren, um die anrückenden Wirbel einer Voruntersuchung zu unterziehen. Zwei dieser Geräte möchte ich heute genauer vorstellen. Sie zeigen noch einmal deutlich, wie groß […]
Die #MOSESeddyhunt hat begonnen / The #MOSESeddyhunt has begun
(English below) Am 23.11. sind wir planmäßig aus Mindelo ausgelaufen. Die ersten Tage auf See waren sehr arbeitsintensiv. Alle Geräte an Bord mussten vorbereitet werden und die Routine an Bord musste sich einspielen. Währenddessen werten Kollegen in Kiel und am HZG Satellitenbilder aus der Region aus und erstellen Computersimulationen der Wirbelbewegungen. Zusammen mit den Echtzeitdaten […]
Auf der Jagd nach den Wirbeln – Die #MOSESeddyhunt startet / The #MOSESeddyhunt starts
(English version below) Langsam wird es spannend. Forscherinnen und Forscher aus Kiel, Geesthacht, Kaiserslautern, Bremen, Aachen sowie von den kapverdischen Inseln legen derzeit im tropischen Nordostatlantik ihre Daten-Netze aus. Netze, in denen sie einen Eddy fangen wollen. Am besten sogar mehrere. Eddy? Wer – oder was – ist das eigentlich? Also, bevor wir die Jagd […]
The expedition starts with the setup of the equipment

With all equipment on deck, the setup in the different labs and on deck could start. Melf installed a mast on […]

Who is eating the organic material in the OMZ off Peru?
As mentioned in the previous blog entries, the area off Peru is very special, because parts of the water column contain low oxygen concentration or oxygen is even completely absent. I am interested in the very small inhabitants of the water column which adapted to live in the oxygen rich as well as in the […]
What you can’t see- greenhouse gases from the Ocean
Usually, when talking about greenhouse gases, one would think of carbon dioxide, which indeed is very important regarding the Earth climate and human made climate change. But there are two greenhouse gases, which are actually much stronger than carbon dioxide: Methane, with a warming potential 30 times as strong as carbon dioxide, and nitrous oxide, […]
Oceans of plastics
Since three weeks we are sampling the waters off Peru, which is an area we explore since almost ten years. We came here for several large scale surveys, the first one took place in 2008, then 2012, 2013, 2015. From the beginning of this cruise on, we observed a lot of plastic trash in the […]
Happy birthday, dear Martha!
“Es gibt me(e)hr als du siehst” – There is more than you se(a)e
Following this attitude we are not getting tired of collecting water. After 17 days on sea we have sampled 80 CTD casts containing roughly 19200 L of water. We usually collect the water from as deep as 2000m up to the surface. The water from each single depth gets analyzed for standard oceanographic parameters like […]
