RV Investigator Voyage IN2014_E04 EM710 Multibeam Echosounder Data

This record describes multibeam echosounder data collected on RV Investigator voyage IN2014_E04 which departed Hobart on the 26 Nov 2014 and returned to Hobart on the 28 Nov 2014. The Kongsberg EM710 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information East of Hobart. Ping rate varied according to depth. Data are stored in *.all raw format at CSIRO Oceans and Atmosphere. There are 50 files totalling 4.89 GB of raw data in this dataset. 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.

本记录所载为“调查者号”（RV Investigator）科考船IN2014_E04航次采集的多波束测深仪（multibeam echosounder）数据，该航次于2014年11月26日从霍巴特起航，同年11月28日返回霍巴特。本次数据采集采用康斯伯格（Kongsberg）EM710型多波束测深仪，获取霍巴特以东海域的海底地形与海底反向散射强度数据。脉冲发射频率（Ping rate）随水深变化调整。原始数据以.all原始格式存储于澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气分部。本数据集共包含50个原始数据文件，总数据量达4.89 GB。数据采集过程中已针对该数据集应用声速剖面校正，但处理后的数据未进行潮汐校正。处理后的数据提供XYZ与GSF格式版本。本数据集的补充说明详见GSM数据采集与处理报告。额外数据产品可按需申请获取。
