Ziel der Reise / Objectives of Cruise:
The oceanic region between Cape Verde Islands and Mauritania is expected to be a hot spot of trace gas emissions and iron input to the ocean because it is site of very high biological productivity, intensive coastal upwelling processes and atmospheric deposition of Sahara dust. The major objective of Poseidon cruise P348 was to investigate the biogeochemical cycling of climate-relevant trace gases (carbon dioxide, nitrous oxide, methane and halogenated compounds) as well as the aerosol deposition in the Eastern tropical North Atlantic Ocean. Along a West-to-East transect at 18?N and a grid of stations off Mauritania, covering open ocean and upwelling areas, 23 stations were sampled.
