This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2018_V05, 'How does a standing meander southeast of Tasmania brake the Antarctic Circumpolar Current?' which departed Hobart on the 16th October 2018 and returned to Hobart on the 16th November 2018. The objectives of the voyage included: (1) Deployment of a fleet of EM-APEX profiling floats, (2) Deployment of a tall mooring at the crest of a meander in the Polar Front of the Antarctic Circumpolar Current, (3) Full-depth hydrographic survey of the physics and biogeochemistry of the targeted ACC meander, conducting transects across the front and (4) Triaxus transects across and along the front. The Simrad EK60 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 1500 m, from Hobart to Hobart. All frequencies were logged continuously (with the exception of occasional cessations required for acoustically quiet periods) for the extent of the voyage. The frequencies were set to passive during sensitive VMP deployment periods of the voyage in the ACC, when acoustic silent periods were requested by the science party. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 1221 files totalling 105 GB of raw data in this dataset. No processing has been conducted on this data. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
