| Summary: | Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. Processed data are SV corrected (xbt or sea surface temperature), tide not corrected and edited using CARIS version 8.1 Credit CSIRO O&A - Geophysical Survey and Mapping (GSM) group This record describes multibeam echosounder data collected on RV Investigator voyage IN2015_E01, which departed Hobart on the 29 Jan 2015 and returned to Hobart on the 19 Feb 2015, after successfully testing equipment at 65° south. The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information in from Hobart to Antarctic waters. Ping rate varied according to depth. Data are stored in *.all raw format at CSIRO Oceans and Atmosphere. There are 389 files totalling 11.4 GB of raw data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Tide corrections were not applied to the processed data.
