Full description

This record describes sub bottom profiler data collected on RV Investigator voyage IN2019_V06, titled 'Tropical observations of atmospheric convection, biogenic emissions, ocean mixing, and processes generating intra-seasonal SST variability' which departed Darwin on the 19th of October 2019 and returned to Darwin on the 17th of December 2019 ,consisting of two legs.

Leg 1 - Darwin, 20:00, 19 October 2019 to Darwin, 19:00, 10 November 2019

Leg 2 - Darwin, 20:00, 11 November 2019 to Darwin, 08:00, 17 December 2019

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 across the voyage transits between research stations and then turned off once stationary.

Data are stored in *.raw and *.segy formats at CSIRO.

Leg 1 contains 787 files totalling 13.4 GB of raw data, and *.segy (780 files 13.9 GB) formats at CSIRO

Leg 2 contains 894 files totalling 9.7 GB of raw data, and *.segy (886 files 9.6 GB) 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
