RV Investigator Voyage IN2015_E05 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2015_E05, which departed Hobart 2015-05-01 and returned on 2015-05-05.

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 (31 files 3.17 GB) raw and *.seg (31 files 3.16 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IN2015_E05采集的海底剖面仪（sub bottom profiler）数据，该航次于2015年5月1日从霍巴特启航，2015年5月5日返航。

本次数据采集使用康斯伯格（Kongsberg）SBP120型海底剖面仪，可获取海底下方不同沉积界面的镜面反射信号。该SBP120的角分辨率为3°×3°。

该回声测深仪（echosounder）的扫频范围为2.5~7 kHz。本次航次全程连续记录了SBP120的采集数据。

数据以*.raw格式（共31个文件，总大小3.17 GB）与*.seg（即SEG-Y格式）（共31个文件，总大小3.16 GB）存储于CSIRO。

SEG-Y格式数据经过实时处理流处理，该处理流包含增益调整、增益校正、带复制品整形的匹配滤波（matched filter）、瞬时振幅属性计算与时变增益处理。
