Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2022_V02, titled "Sedimentation at its extreme: how powerful are submarine caldera-forming eruptions (Kermadec arc)?" The voyage took place between March 15, 2022 and April 19, 2022 (AEST), departing from Hobart and returning to Hobart. The main area of survey was the Kermadec arc off of northern New Zealand.

The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter between Hobart and New Zealand and the survey areas within the Kermadec Arc region.

The EM122 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz.

Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 755 *.all files totaling 49.9 GB of raw bathymetry/backscatter data and 754 *.wcd files totaling 65.6GB of watercolumn data 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 was computed using the EGM2008 model and applied to the processed data. Processed data had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff format.

Additional information regarding this dataset, including information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
