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 […]
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 […]
A group of three, we’re the zooplankton-and-nekton-people on board. We are interested in how environmental drivers such as oxygen, temperature or light shape the distribution of pelagic animals. “Pelagic” means “in the water column”, so most of these animals hardly see the seafloor or the ocean’s surface, but occupy the three-dimensional space in between. If […]

Gestern haben wir erfolgreich IFM 07, den ersten von zwei Glidern, geborgen. Er ist schon ein alter Hase unter den GEOMAR Glidern und hat sehr zuverlässig viele Messfahrten im Pazifik und Atlantik absolviert. Ähnlich wie Segelflugzeuge in der Luft, schweben Glider durch die Ozeane und können unterschiedliche Parameter messen – je nachdem, welche Messgeräte man […]
In order to understand Ocean-Atmosphere exchange processes, Tim and I went off the Meteor and did a sampling of the top 10 m of the water column with the Zodiac. We took water samples with a Niskin bottle and a pump system in order to understand the structure of the surface layer in a […]
The currents and the biological activity near the coast of Peru are such that nearly all the oxygen disappears between 50 and 500m depth. This affects life from microbes to large fishes. We are currently onboard the FS METEOR to try to understand why and how this occurs. Carolina Cisternas-Novoa and myself, Frédéric Le Moigne […]
