Ziel der Reise / Objectives of Cruise:

Using dedicated process studies and long term observations, the GENUS project aims to clarify the interactions between the particular trophic levels of the upwelling ecosystem in order to improve the knowledge about the system and to enhance the predictive capabilities of ecosystem models. The cruise M103/2 was dedicated to a filament and succession study. This study consisted of a high spatial resolution measuring program in a single upwelling filament of the northern Benguela, which can be found throughout the year. The focus of this study was on filament dynamics, offshore transport of coastal waters and plankton communities in the filament, and the biogeochemical fluxes between the filament and ambient waters. Satellite images of TMI/AMSRE were used to identify a feasible filament and to select the positions of transects for data collection. The in situ measurements were carried out with a combination of towed instruments for basic hydrographic data with high spatial resolution (ScanFish, TADCP), station work for sampling the filament (CTD probe, nets) and a drifter deployment. The upwelling filament was covered with three cross shelf transects from the coast towards the open ocean (ca. 120n.m. length) and an along shore transect crossing the axis of the filament (ca. 80n.m. length). Each transect was sampled with 16 stations. Eight stations at each transect were selected for an intense interdisciplinary sampling that supplied hydrographic, biological and biogeochemical data in parallel.
