RV Investigator Voyage IN2020_V08 EK80 Echosounder

This record describes scientific split-beam echosounder data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2020_V08, titled "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters." The voyage took place between December 5, 2020 and January 16, 2021 departing from Hobart (TAS) and arriving in Hobart (TAS).The Simrad EK80 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 1500 m, at the three study locations and transit to and from Hobart . All frequencies were logged continuously for the extent of the voyage. Logging of "complex samples" occurred daily for one hour.Data are stored in *.raw (6273 files 625 GB) and *.idx (6273 files 63.0 MB) formats at CSIRO.No processing has been conducted on this data.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
