Description
Summary:Bathymetry based on data recorded during RV HEINCKE HE449 between 01.08.2015 and 22.08.2015 in the Norwegian Sea. The aim of the cruise was to explore gas emissions using the echosounders of the ship along the slope of the Barents Sea up to Svalbard to find more evidence for dynamic changes of gas hydrates and emissions of free gas. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry post-processing and its products. Description of processed data sources: During the RV HEINCKE cruise HE449 the Kongsberg EM710 shallow multibeam echosounder with a nominal sounding frequency of 70-100 kHz was utilized. 256 beams (and up to 800 soundings with equidistant and dual swath mode) are formed for each ping with a 1°(Tx)/2°(Rx) footprint while the seafloor is detected using amplitude and phase information for each beam sounding. For further information consult: http://epic.awi.de/26726/1/Kon2007b.pdf. During the surveys the EM710 system crashed two times but the resulting gaps ...
