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 1 m resolution. We took samples mainly for nitrous oxide (N2O), which is one of the strongest greenhouse gases on Earth, and which is produced at high rates when the Ocean loses oxygen. We further collected DNA samples to identify organisms involved in N2O production and other surface Ocean processes.
Our trip was accompanied by a group of sealions which were very interested in what we were doing- they stayed around the Zodiac for the whole sampling time of 2 h.
