Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM107 using a Kongsberg EM 712 multibeam echosounder. The expedition took place during 18.05.2022 and 03.06.2022 from Bremerhaven (Germany) - Tromsø (Norway) in the Northern Atlantic Ocean. Data were recorded outside EEZs. 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. The main aim of MSM107 was to study organic matter formation, transport and transformation on and off the western Irish shelf. The research is part of a larger research project to quantify the contribution from shelf production to deep ocean carbon storage. Acquisition and provision of the data are part of the DAM Underway Project
