Multibeam bathymetry processed data (Reson SeaBat 7160 entire dataset) of RV TARAJOQ during cruise TRJQ_2022-05, TRJQ_2023-05, 202310_MB_TRJQ & TRJQ_2024-05, West Greenland shelf

High-resolution multibeam data were collected with RV Tarajoq (2022-2024) from the West Greenland shelf (Disko region to Melville Bay) as part of the seafloor mapping strategy at the Greenland Climate Research Centre. The goal of the strategy is to map and illustrate geomorphic features on the seafloor, including geohazards and ice-sculpted forms. Data were acquired with hull-mounted Teledyne system SeaBat 7160 operated at frequency 44 kHz. Positioning and movements of the vessel were obtained from the Applanix POS MV Ocean Master receiving data from an Inertial Motion Unit and two Trimble GNSS antennas. The accuracy of the observations is generally within 0.5 to 2 m horizontally and up to 0.03 degrees roll, pitch, and heading of the vessel. The bathymetry data were acquired with Qinsy software, SVP-corrected, and cleaned using Qimera software, and further gridded at 10 x 10 m resolution. Tide correction was not applied.
