This record describes sub bottom profiler data collected on RV Investigator voyage IN2018_T02, 'Harmful Algal Blooms and their long term sediment record in East Coast Tasmanian waters' which departed Brisbane on the 14th May 2018 and returned to Hobart on the 21st May 2018. The overall objective of this transit voyage was aimed at addressing the following research topics:1. Harmful Algal Blooms and their long term sediment record in East Coast Tasmanian waters; 2. Spatial and temporal variability in the distribution and abundance of seabirds and 3. Remote-ROAM: mobile modelling sea trials. 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 continuously for the extent of the voyage. Data are stored in .raw (46 files 9.82 GB) raw and .seg (44 files 9.73 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
