Abstract:
Raw water column data were collected aboard RV MARIA S. Merian during cruise MSN141/2 using a Kongsberg EM 124 multibeam echosounder. The expedition took place during 2025-12-09 – 2025-12-22 from Rio de Janeiro (Brazil) to Las Palmas (Spain) in the Atlantic. The main goal of MSM141/2 is to collect reference data for satellite remote sensing of atmospheric properties. The focus is on the properties of clouds, aerosols, and trace gases near tropical convection. From a biological perspective, water samples will be taken from various depths along the transect, their DNA extracted, and the horizontal and vertical distribution of single-cell organisms will be investigated using group-specific primers. Furthermore, Sargassum will be examined for macroinvertebrates and the gut contents. Data were recorded solely in international waters. 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. Data acquisition was done by the University of Cologne, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles.
