This record describes the End of Voyage (EOV) archive from the Marine National Facility (MNF) RV Investigator research voyage in2017_v01, titled "Interactions of the Totten Glacier with the Southern Ocean through multiple glacial cycles." The voyage took place from Hobart (TAS) to Hobart between January 14 and March 5, 2017. NOTE: the raw USBL data files lag 3 minutes behind the ship’s time due to an error with the NTP client. This only applies to the raw files directly logged by the USBL in the /usbl folder; and does not affect the TECHSAS recorded data, which is synchronized to the ship’s clock.
