Brief description

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2015_E04 titled "Trial voyage – trace metals and micronutrients". The voyage took place between April 24 to April 27, 2015, departing from Hobart (TAS) and arriving in Hobart (TAS).

The purpose of the voyage was to test trace metal equipment (CTD and McLane pumps) and the trace metal clean underway seawater supply. Aerosol sampling was also undertaken to acquire trace metal atmospheric measurements.

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 South-Eastern Tasmania, produced from the processed EM122 and EM710 bathymetry data.

Lineage

Data processing for the EM122 and EM710 data was performed using CARIS 8.1.8. Data from both systems were imported into a single CARIS project using different vessel files, Investigator_EM122 and Investigator_EM710. A zero tide file was applied to the data before merging. The data was investigated for outliers.

The data was gridded at multiple resolutions in python Caris batch script using a Depth filter Vs Resolution guideline derived from AusSeabed Multibeam guidelines v2 and further inspected for outliers. Final raster products are available in L3 folder of this collection. Final processed data were also exported per line as GSF and ASCII format and available in the L2 folder of this collection.
