Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM123 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 2023-11-23 - 2023-12-27 from Halifax (Canada) to St. John's (Canada) in the Labrador Sea. Data were recorded in the EEZs of Brasil and Cape Verde and outside. The aim of MSM123 is to understand and quantify bubble-mediated gas exchange mechanisms in the Labrador Sea (BELS). 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.

These data should not be used for navigational purposes.
