Abstract:
Hydroacoustic evidence of submarine gas emissions was repeatedly acquired on a seepage area offshore Prins Karl Forland, Svalbard. The data set was collected with EK60 scientific echosounders during 11 surveys conducted between 2008 and 2014 on board the RV Helmer Hanssen and the RRS James Clark Ross. This information contains large amount of acoustic flares, which are the hydroacoustic expression in echograms of underwater bubble release. The acquisition and compilation of this information is a result of the international cooperation between several institutions, i.e. GEOMAR Helmholtz Centre for Ocean Research (Germany), the University of Southampton (United Kingdom), the National Oceanography Centre (NOC, United Kingdom), Centre for Arctic Gas Hydrate (CAGE, Norway) and the Renard Centre of Marine Geology (RCMG, Belgium). The data allowed the first spatiotemporal variability analysis of submarine bubble seepage offshore Prins Karl Forland and the first quantitative comparison over several years using hydroacoustic information.
