RV Investigator Voyage IN2024_T02 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2024_T02, Brisbane to Singapore Transit which departed Brisbane on the 8th July 2024 and returned to Singapore on the 23rd July 2024.

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 (982 files 23.8 GB) raw and *.seg (970 files 23.5 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.

本记录描述了探索者号（RV Investigator）科考船航次IN2024_T02期间采集的浅地层剖面仪（sub bottom profiler）数据，该航次为布里斯班至新加坡过境航次，于2024年7月8日从布里斯班启航，2024年7月23日返回新加坡。
本航次使用康士伯（Kongsberg）SBP120浅地层剖面仪采集数据，该设备可获取海底下方不同沉积界面的镜面反射信号。SBP120的角分辨率为3°×3°。
该SBP120的回声测深模块扫频范围为2.5至7 kHz。SBP120在整个航次期间均持续记录数据。
相关数据存储于澳大利亚联邦科学与工业研究组织（CSIRO），包含两种格式：*.raw原始格式（共982个文件，总容量23.8 GB）与*.seg（SEG-Y）格式（共970个文件，总容量23.5 GB）。
SEG-Y格式数据搭载了实时处理流程，该流程包含增益应用、增益校正、带副本整形的匹配滤波、瞬时振幅属性计算以及时变增益处理。
