This record describes sub bottom profiler data collected on RV Investigator voyage IN2018_V02 , "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania" and "Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site" which departed Hobart on the 03 March 2018 and returned to Hobart briefly on 12 March and finally concluded on the 21 March 2018 in Hobart. Unfortunately a hardware error caused the instrument to be turned off from 5 March 2018. The Kongsberg SBP120 (sub bottom profiler) was used to acquire data containing the specular reflections at different sediment interfaces below the seafloor. The SBP120 provides a 3° by 3° angular resolution. The echosounder's frequency sweep range is from 2.5 to 7 kHz. The SBP120 was logged sporadically for the extent of the voyage. Data are stored in .raw (23 files 2.43 GB) raw and .seg (27 files 2.41 GB) segy formats at CSIRO. The segy format data had a real time processing stream applied, which applies gain, a gain correction, matched filter with replica shaping, an attribute calculation for instantaneous amplitude and time variable gain. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request
