Abstract

We deployed KOSMOS units in different climate zones and marine ecosystem types between 2011 and 2015, in order to study the influence of ocean acidification on the succession of plankton communities under in-situ conditions. Settling particulate matter within the mesocosms was quantitatively collected in sediment traps attached to the bottom of the mesocosms. We applied a low vacuum sampling strategy to empty these particle traps through silicon tubes reaching down from the sea surface outside of the mesocosm enclosures. The video shows the setup of the traps and the sample recovery from small boats attached to the KOSMOS units.

The video can be downloaded from the OceanRep server (GEOMAR) but is also available on the KOSMOS channel of the streaming platform YouTube.
