REM Etive Voyage RE2017_C01 Operation and Sampling Detail Logs and Locations

This record describes the operations undertaken and geological sample data collected on the Fugro vessel REM Etive Charter Voyage RE2017_C01, titled "Great Australian Bight (GAB) Deep Water Geological and Benthic Ecology Program." This charter voyage took place from Hobart to Adelaide between the 13th of March and the 6th of April, 2017.

The voyage, undertaken over 25 days, was a great success with 33 researchers from several research organisations and the vessel crew undertaking 40 operations over 5 target areas in water depths ranging from 1000 m to 3000 m. The voyage deployed a diverse range of instrumentation fully utilising the REM Etive capabilities which included two work class Remotely Operated Vehicles (ROV) and a Sea Floor Drill. This also involved the deployment of these equipment types significantly deeper than previous deployments either in Australia or worldwide. The data and samples collected significantly augment the sparse data and sample collections within the deep water GAB to date.

Over 54 pieces of rock were individually collected by the ROVs, plus 162.98m of core drilled. This record contains data recorded during the survey including the activity log, observation log, operation log, a log of general photographs taken, descriptions of geology collected, biology catch locations, details of samples taken for analysis and the daily "Trip" details which defined the daily reporting periods.

The Seafloor Drill 80mm diameter X 1m long Core sections were split and sampled for geochemical analysis. Remainders of the cores have been archived. Sampled half of the core at room temperature at the Perth Core Library, 37 Harris Street, Carlisle, WA 6101 phone [phone].

本记录详述了Fugro旗下科考船REM Etive在航次RE2017_C01期间开展的作业及采集的地质样本数据，该航次项目名称为"大澳大利亚湾（Great Australian Bight，简称GAB）深水地质与底栖生态计划"。本次包租航次于2017年3月13日至4月6日期间，从霍巴特航行至阿德莱德。

本次航次历时25天并取得圆满成功：来自多家科研机构的33名研究人员与科考船船员，在5个目标作业区域完成了40次作业，作业水深介于1000米至3000米之间。本次航次部署了多样化的科考设备，充分发挥了REM Etive的作业能力，其中包括2台作业级遥控无人潜水器（Remotely Operated Vehicle，ROV）与1台海底钻机（Sea Floor Drill）。此次设备部署的作业深度显著超越了澳大利亚乃至全球此前的同类作业纪录。本次采集的数据与样本，极大充实了迄今为止大澳大利亚湾深水区域稀缺的地质与生态数据及样本储备。

遥控无人潜水器共单独采集了54块岩石样本，同时完成了162.98米的岩心钻探。本记录包含本次科考期间记录的各类数据，具体包括作业日志、观测日志、操作日志、常规摄影日志、采集地质情况描述、生物捕获点位信息、待分析样本的详细信息，以及界定每日报告周期的每日"航次片段"详情。

本次使用的海底钻机所采集的岩心直径为80毫米、单段长度1米，经切割分半后，其中一半被送至位于西澳大利亚州卡莱尔市哈里斯街37号的珀斯岩心库（邮政编码6101，联系电话：[phone]），于室温环境下开展地球化学分析采样，剩余岩心样品已完成归档留存。
