The voyage took place between March 15, 2022 and April 19, 2022 (AEST), departing from Hobart and returning to Hobart.The main area of survey was the Kermadec arc off of northern New Zealand.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. General settings used were Linear Chirp Up, Matched Filter, 10 ms pulse length, 250 ms window size. Sub bottom profilers in general do not perform well with hard rocky substrates and/or steep and irregular terrain. The working area was subject to these limitations which made SBP data acquisition challenging and affected the resultant data.

Instantaneous amplitude and time variable gain were not applied on acquisition.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.

Full description

This record describes sub bottom profiler data collected on RV Investigator voyage IN2022_V02, titled "Sedimentation at its extreme: how powerful are submarine caldera-forming eruptions (Kermadec arc)?" The voyage took place between March 15, 2022 and April 19, 2022 (AEST), departing from Hobart and returning to Hobart.The main area of survey was the Kermadec arc off of northern New Zealand.

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. General settings used were Linear Chirp Up, Matched Filter, 10 ms pulse length, 250 ms window size. Sub bottom profilers in general do not perform well with hard rocky substrates and/or steep and irregular terrain. The working area was subject to these limitations which made SBP data acquisition challenging and affected the resultant data. The SBP performed well over areas with flat seafloor.

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 (744 files 12.5 GB) raw and *.seg (738 files 12.4 GB) segy formats at CSIRO.

The segy format data had a real time processing stream applied, which applies gain, a gain correction and matched filter with replica shaping. Instantaneous amplitude and time variable gain were not applied on acquisition.

Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products, including processed *.segy files with instantaneous amplitude applied, may be available on request.
