Raw bathymetry data collected from a hull-mounted Kongsberg EM2040 multibeam echosounder during RV Skagerak SK2514 cruise, 2025

GB/NERC/BAS/PDC/02225

Abstract:
Presented here is the raw multibeam bathymetry data acquired from 2025-08-16 to 2025-08-18 as part of RV Skagerak SK2514 research cruise also referred to as KANG-GLAC #2. Bathymetry data were collected using a Kongsberg EM2040 multibeam echo-sounder installed on RV Skagerak. Data are provided in raw Kongsberg format (.all). Data are unprocessed and therefore may contain incorrect depth measurements without further processing.

KANG-GLAC is a NERC funded project to investigate how the accelerating decay of the Greenland Ice Sheet will progress with climate change, and to better understand the knock-on effects this will have on ocean circulation and marine productivity. This work was funded by Natural Environment Research Council (NERC) grant NE/V006509/1.

Additional Information

Reference:
Quality:	Presented here is the raw data. The data have not been corrected for vertical datum and no tide model was applied. No quality check has been performed. Data are not to be used for navigation.
Lineage/Methodology:	R/V Skagerak is equipped with a Kongsberg EM 2040 multibeam echosounder (MBES). This system is a high-resolution, dual RX (receiver), single swath, 200 kHz system, designed for detailed seafloor mapping up to ~500 m depth. The EM 2040 multibeam echosounder collects data including depth measurements, backscatter intensity, and water column information, providing a comprehensive picture of the seafloor. The data acquisition software used to collect information from the multibeam sonar is SIS (Seafloor Information System) version 4.3.2.
