Full description
This record describes gravity 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 gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. The gravity meter was running for the duration of the voyage except for the period between 26-03-2022 05:00 and 29-03-2022 11:05 UTC when no data was acquired from any ship system as mandated and for a period of bad weather from 2022-04-12 18:01:50 until 2022-04-14 00:32:46 UTC. There are 70 files totaling 540 MB of raw data in this dataset. Wharf ties were undertaken prior to (13 March 2022) and after the voyage (19 April 2022) at the Hobart wharf using a Scintrex Autograv CG-5. Wharf tie data can be found in Hobart wharf_tie_2022_03_13.txt and Hobart wharf_tie_2022_04_19.txt, which is stored with the raw data. An Excel spreadsheet detailing the wharf tie metadata and associated waterline measurements is also stored with the raw data.
Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
