IN2015_V01 Southern Ocean IMOS Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2015_V01 titled "IMOS Southern Ocean time series automated moorings for climate and carbon cycle studies southwest of Tasmania". The voyage took place between March 21 and March 30, 2015, departing from Hobart (TAS) and arriving in Hobart (TAS) The primary objective was to deploy 3 moorings and retrieve 1, as well as other sampling. Multibeam data was required to assist in verifying deployment sites. Bathymetry data from this site, had previously been collected on Southern Surveyor using the EM300. The EM122 provided much improved data coverage of the area, and extra mapping was undertaken at night where possible. As mooring work was undertaken during the day most multibeam data acquisition was monitored. This dataset is published with the permission of CSIRO. Not to be used for navigational purposes. The dataset contains bathymetry grids of 10m to 210m resolution of the Southern Ocean, produced from the processed EM122 and EM710 bathymetry data.
