RV Investigator Voyage IN2018_V05 Gravity Data

This record describes gravity data collected on 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 gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 64 files totalling 514 MB of raw data in this dataset. Wharf ties were not undertaken. Gravity data was acquired for the full duration of the voyage from Hobart to Hobart.No processing has been conducted on this data.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
