Abstract:
Raw multibeam bathymetry data were collected aboard RV SONNE during cruise SO295 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 2022-10-31 - 2022-12-23 from Port Hueneme to Port Hueneme (USA ) in the central Pacific Ocean. SO295 builds on the results of the European collaborative JPI Oceans project "MiningImpact2" that assesses environmental impacts of polymetallic nodule mining. Data were recorded outside EEZs. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Acquisition and provision of the data are part of the DAM Underway Project and published according to the FAIR principles.
