Full description

This record describes Simrad SH90 high definition omnidirectional fishery sonar, 114 kHz data collected on RV Investigator voyage IN2019_V01, titled "The availability of Antarctic krill to large predators and their role in biogeochemical recycling in the Southern Ocean" which departed Hobart on the 19th January, 2019 and returned to Hobart on the 5th of March, 2019.

The Simrad SH90 provides detailed information about school density, speed, depth, heading and size, with an operational frequency of 114 kHz. The SH90 was logged sporadically to guide krill fishing, and settings were updated/changed constantly with respect to angles and frequencies in real time to point to the krill schools while trawling.

Data are stored in Simrad *.raw format at CSIRO. There are 12,861 files totalling 378 GB of raw data in this dataset.

The data is available "as is" without any Quality Control measures, post processing or standardized settings.

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