Abstract:
Multibeam bathymetry raw data using the ship's own Kongsberg EM 710 multibeam echosounder was not continuously recorded during RV Heincke cruise He525. Data were recorded on 3 days between 2019-03-05 and 2019-03-07 in the German North Sea and data acquisition was continuously monitored during the survey. The survey was targeted to cover occurences of boulders in the North of Helgoland.
Before data acquisition, sound velocity measurements using a sound velocity profil (SVP) probe were applied on the data for data calibration and are part of this dataset publication (He525_SVP_20190305.txt). Data are unprocessed and therefore may contain incorrect depth measurements without further processing. Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2017).
