RV Investigator Voyage IN2017_V04 ME70 Multibeam Fisheries Echosounder Data

This record describes ME 70 scientific multibeam fisheries echosounder data collected on RV Investigator voyage IN2017_V04, 'The whole enchilada: from production to predation in Tasman Sea ecosystems' which departed Brisbane on the 31-Aug-2017 and returned to Sydney on the 18 September 2017.

The Simrad ME70 scientific multibeam echosounder acquired acoustic backscatter data through the water column. The echosounder's frequency range is from 70 kHz to 120 kHz. The ME70 logged sporadically for most of the voyage, but logged continuously near Montague Island.

Data are stored in Simrad *.all raw format at CSIRO. There are 173 files totalling 15 GB of raw data in this dataset.

No processing has been conducted on this data.

Additional information regarding this dataset, including the settings used, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.

本记录记述了“探索者”号科考船（RV Investigator）航次IN2017_V04期间采集的Simrad ME70型科学多波束渔业回声测深仪数据，该航次主题为“‘The whole enchilada’: 塔斯曼海生态系统从生产到捕食的全过程”，于2017年8月31日从布里斯班启航，2017年9月18日返回悉尼。

Simrad ME70型科学多波束回声测深仪通过水体采集了声学背散射数据。该测深仪的工作频率范围为70 kHz至120 kHz。本次航次的大部分时段，该测深仪均为间断式记录，但在蒙塔古岛附近采用连续记录模式。

本数据集的数据以Simrad *.all原始格式存储于澳大利亚联邦科学与工业研究组织（CSIRO），共包含173个文件，总原始数据量达15 GB。

本数据集未经过任何处理。

有关本数据集的更多信息（包括所用采集配置参数），均收录于GSM数据采集与处理报告中。额外的数据产品可应申请提供。
