Abstract:
Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM116 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 2023-04-03 – 2023-05-07 from Montevideo (Uruguay) to Recife (Brazil) in the Southern and Central Atlantic Ocean. Data were recorded outside EEZs. MSM116 focused on to obtain sequences of very well-preserved deposits of calcareous microfossils from relatively shallow water depths (in reach of the MeBo200 coring device) and paleo-water depths (thus with potentially good preservation), and therefore allow the study of surface and bottom water temperatures, ẟ18O-seawater, and related paleoceanographic parameters to establish climatic boundary conditions during
past "warmer worlds". Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Acquisition and provision of the data are part of the DAM Underway Project and are according to the FAIR principles.
