| contents | Raw water column data were collected aboard RV ALKOR during cruise AL575 using a 50kHz Elac Seabeam 3050 (SB3050 MKII) multibeam echosounder by ELAC Nautic. This system had been installed originally on the former RV POSEIDON and was transferred to RV ALKOR just before this cruise. During AL575 it was mainly used it to acquire water column data for online gas seep detection. Water column and side scan data are stored in .wci & .raw format; bathymetry and backscatter data are stored as .xse. .xse data can either be read directly in MBSystem, Hypack or Qimera post-processing software or they can be converted to .hsx (Caris readable). The expedition took place during 2022-06-28 – 2022-07-13 from Kiel to Kiel (Germany) in the North Sea. The major aim of AL575 - GEOSTOR leak are to investigate and contribute to the assessment of the mechanisms and potential risks of CO2 leakage along boreholes drilled through the sedimentary overburden above subseafloor storage formations in the North Sea. Data were recorded in the EEZs of UK and Germany. Sound velocity profiles (SVP) were applied on the data for calibration. Please see the cruise report for details. The data are unprocessed and can therefore contain incorrect measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data acquisition and provision was done by GEOMAR and they are published according to the FAIR principles. |
