Abstract:
This dataset was collected during research cruise M182 (MOSES Eddy-III), conducted within the framework of the Helmholtz Association's Modular Observation Solutions for Earth Systems (MOSES) infrastructure and the BMBF-funded project REEBUS ("Role of eddies in the carbon pump of eastern upwelling systems – Demonstration Case Canary Current System"). The cruise investigated the influence of ocean eddies on carbon cycling and biogeochemical processes in the eastern boundary upwelling system of the northern tropical Atlantic. Sediment samples were collected along the Cape Verde Terrace and towards the oxygen-deficient waters offshore Mauritania using multicorers (MUCs), gravity corers (GCs), and the Biogeochemical Observatory (BIGO) lander system. Porewater and solid-phase sediment analyses were performed to characterize sediment diagenetic processes, organic carbon burial rates, and carbon burial efficiencies. Special emphasis was placed on the biogeochemical cycling, distribution, and burial of redox-sensitive elements, including nitrogen (N), phosphorus (P), and iron (Fe), and their relationship to benthic oxygen respiration rates. The dataset further contributes to understanding how seafloor topography and eddy-driven processes influence carbon turnover and biogeochemical functioning in deep-sea ecosystems.
