Ziel der Reise / Objectives of Cruise:

The cruise POS533 of RV Poseidon investigated atmosphere-ocean-island-biogeochemical cycles in the Macaronesian region. It intended to capture natural and anthropogenic interactions in this dynamic region and to analyze the impact of the coupled dynamic atmospheric and oceanic processes on the air-sea exchange of climate-active gases. The cruise was organized and conducted in collaboration with scientists from GEOMAR, Madeira, the Canaries and Cape Verde. A huge interdisciplinary atmospheric, oceanic biogeochemical and planktonic dataset was obtained from the cruise. The main goals of the expedition are: 1.Understand the sources, distribution, emissions, gradients and transport of bromoform and other trace gases from urbanized coastlines into the open ocean. We will use bromoform (CHBr3), a halogenated, volatile compound, formed in large quantities during water disinfection as a proxy to trace coastal water and air transport, to quantify its abundances and sources and try to assess its local, regional and possibly global impact. 2.Testing bromoform and other halocarbons to differentiate between the anthropogenic and natural imprint of the island-induced biogeochemical enhancement of nutrients and productivity in the oligotrophic region around the Macaronesian islands. 3.Identification of the air-sea fluxes and atmospheric transport of terrestrial natural and anthropogenic trace gases to assess a possible deposition and impact on marine biogeochemical cycles 4.Identify biogeochemical signatures and microbial community differences between on- and off shore regions of the Macaronesian islands and their relation to trace gas abundances.
