RV Investigator Voyage IN2019_E01 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2019_E01, 'Post-Dry Dock Calibration Trials' which departed Singapore on the 19th July 2019 and returned to Cairns on the 2nd August 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/sporadically] for the extent of the voyage.
787 files 15.8 GB) raw and *.seg (763 files 15.6GB) 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'干坞后校准试验'航次（RV Investigator调查船IN2019_E01航次）采集的浅地层剖面仪（sub bottom profiler）数据。该航次于2019年7月19日从新加坡出发，2019年8月2日返回凯恩斯。

本次航次使用Kongsberg SBP120浅地层剖面仪采集数据，该数据包含海底以下不同沉积物界面的镜面反射信息。SBP120的角分辨率为3°×3°。

该回声测深仪（echosounder）的扫频范围为2.5至7 kHz。在整个航次期间，SBP120以[持续/间歇性]方式记录数据。

CSIRO存储有787个原始文件（15.8 GB）和*.seg格式文件（763个，15.6 GB），均采用SEGY格式。

SEGY格式的数据经过实时处理流处理，包括增益、增益校正、带复制整形的匹配滤波、瞬时振幅属性计算及时变增益等步骤。
