Abstract | The expedition MSM61 operated off West Africa at the Cape Verde Ocean Observatory (CVOO) time series station as well as at the Senghor Seamount, northeast of Cape Verde islands. Scientific objectives were the investigation temporal variability and long-term changes of physical and biogeochemical parameters off West Africa by contributing and extending the CVOO time series data set. But also determining the variability of diversity and abundance of predators and prey (micronekton and zooplankton) and their linkage to biogeochemical and hydrographic/currents variability at the seamount crest and flanks. Though multibeam data has been recorded, it was not a major focus of MSM58 and the responsible party has not provided further information. |
