The purpose of this voyage was to undertake post port-period equipment calibrations and commissioning, sea trials and personnel training. The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter in Storm Bay and offshore to the southeast of Tasman Peninsula. A patch test calibration was performed to determine the angular offsets of the system. The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 40 to 100 kHz and during this voyage was acquired with a frequency range setting of 70 to 100 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 78 files totalling 14.3 GB of raw bathymetry (.all) data and 76 files totalling 95.6 GB of raw watercolum (.wcd) in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. GPS tide corrections were applied to the processed data using the EGM2008 model (EGM_2008_1Min_Aust_WGS84.csar). Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry in geotiff format.
