Ziel der Reise / Objectives of Cruise:

The cruise combines a wide spectrum of biological, chemical and physical oceanography as well as atmospheric chemistry under a regional focus on the Mauritanian Upwelling. This region is characterized by important SOLAS-relevant phenomena and processes which have major influence on substances (iron, nutrients, CO2, volatile halocarbons) and processes (nitrogen fixation, ocean-atmosphere exchange). Upwelling regions in major dust deposition areas can be viewed as biogeochemical reactors which are fuelled simultaneously by vertical supply of macro and micro nutrients from the mesopelagial below and the atmosphere above. At the same time, these regions provide means of ventilation of radiatively and chemically active trace gases (e.g., CO2, nitrous oxide, bromoform) which are produced sub-surface. The resulting flux densities are sometimes magnitude larger than in the oligotrophic background waters Sampling strategy: hydrographic survey with stations (typically only upper 1000 m) along zonal transects (18?N, 18,5?N, 19?N, 19,5?N, ~20?N) from the open ocean onto the Mauritanian shelf. Additionally six 24h drift Langrangian experiment were carried out with continuous underway and regular CTD sampling at the drifter. Underway measurements on pumped surface and air were performed throughout the cruise. Sampling: CTD/LADCP, ship ADCP, GoFlo samplers, plankton nets, microstructure profiler, underway seawater sampling, air and aerosol sampling.
