RV Investigator Voyage IN2016_V06 SBP120 Sub-bottom Profiler Data

This record describes sub bottom profiler data collected on RV Investigator voyage IN2016_V06, 'Sustained monitoring of the EAC: mass, heat and freshwater transports' which departed Brisbane on the 29th October 2016 and returned to Brisbane on the 13th November 2016.

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 sporadically for the extent of the voyage.

Data are stored in *.raw 17 files 1.2 GB raw and *.seg 17 files 1.2 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.

本数据集记录了“调查者”号科考船（RV Investigator）IN2016_V06航次采集的海底剖面仪（sub bottom profiler）数据，该航次主题为"东澳大利亚洋流持续监测：质量、热量与淡水输运"，于2016年10月29日从布里斯班起航，同年11月13日返回布里斯班。

本航次采用Kongsberg SBP120型海底剖面仪采集数据，该设备可获取海底下方不同沉积物界面的镜面反射信号，其角分辨率为3°×3°。

该回声测深仪的扫频范围为2.5~7 kHz。本航次全程间歇性记录了SBP120的采集数据。

相关数据以两种格式存储于澳大利亚联邦科学与工业研究组织（CSIRO）：包含17个*.raw格式原始文件（总容量1.2 GB）与17个*.seg格式SEG-Y（SEG-Y）文件（总容量1.2 GB）。

SEG-Y格式数据已应用实时处理流程，该流程包含增益调整、增益校正、带副本整形的匹配滤波，以及瞬时振幅属性计算与时变增益处理。
