This record describes SVP data collected on RV Investigator voyage IN2023_V02, titled "Gigantic submarine landslide offshore western Tasmania: risk mitigation for shelf derived tsunami in Australia", which departed Hobart on March 24 and returned to Hobart on April 30, 2023. A total of 17 SVP casts were conducted over the duration of this voyage using a combination of the Valeport MIDAS SVX2 sound velocity profiler (13 casts) and rapidCast SVP (4 casts). The Valeport MIDAS SVX2 was attached to the CTD frame and deployed with the CTD casts, therefore SVP & CTD share common deployment cast numbers. In addition to the SVP cast data, 164 SV profiles were derived from SST (sea surface temperature) data with climatology. Data are stored in ASCII format files at CSIRO. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
