RV Investigator Voyage IN2015_V03 EM122 Multibeam Echosounder Data

This record describes multibeam echosounder data collected on RV Investigator voyage IN2015_V03, which departed Brisbane on the 3rd June 2015 and arrived Sydney on 18th June 2015. The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information in the Tasman Sea. Ping rate varied according to depth. Data are stored in *.all raw format at CSIRO Oceans and Atmosphere. There are 368 files totalling 18.2 GB of raw data in this dataset. 31 sound velocity profiles were applied to this data during data acquisition. Tide corrections were not applied to the processed data.Processed data are available in XYZ and GSF format. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products available on request.

本记录所描述的多波束测深声呐数据采集自“探索者号”科考船（RV Investigator）航次IN2015_V03，该航次于2015年6月3日从布里斯班起航，于2015年6月18日抵达悉尼。本航次采用康斯伯格EM122（Kongsberg EM122）多波束测深声呐，在塔斯曼海采集海底水深地形与后向散射强度数据。声呐脉冲发射速率随探测水深动态调整。原始数据以*.all格式存储于澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）海洋与大气研究部门。本数据集共包含368个原始数据文件，总容量达18.2 GB。数据采集阶段共应用了31条声速剖面进行校正。经处理后的数据集未施加潮汐校正。处理后的数据可提供为XYZ及GSF两种格式。有关本数据集的更多补充信息可查阅《GSM数据采集与处理报告》。额外数据产品可按需申请获取。
