RV Investigator Voyage IN2019_V04 Gravity Data

This record describes gravity data collected on RV Investigator voyage IN2019_V04, 'Hotspot dynamics in the Coral Sea: connections between the Australian plate and deep Earth' which departed Cairns on the 7th August 2019 and returned to Brisbane on the 3rd September 2019.The gravity meter instrument is a MicroG Lacoste Air-Sea II and was run continuously during the voyage in the Coral Sea, within the EEZ of Australia, Papua New Guinea, Solomon Islands and New Caledonia. Data are stored in .ENV and .DAT data files at CSIRO. There are 57 files totalling 463 MB of raw data in this dataset. Wharf ties were undertaken at the start and end of the voyage using a Scintrex Autograv CG-5. Reference station number 2008909952 was used in Cairns (located at Cairns airport) and station number 2016909147 was used in Brisbane (located at Northshore Riverside Park). Wharf tie data can be found in "Cairns_wharf_gravity_tie_in2019_v04.TXT" and "Brisbane_wharf_gravity_tie_post_in2019_v04.TXT", which are stored with the raw data folder.No processing has been conducted on this data.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.本记录描述了‘调查者号’（RV Investigator）科考航次IN2019_V04采集的重力数据，该航次主题为《珊瑚海热点动力学：澳大利亚板块与地球深部的关联》，于2019年8月7日从凯恩斯启航，2019年9月3日返回布里斯班。本次观测采用的重力仪为MicroG Lacoste Air-Sea II型，在航次期间于澳大利亚、巴布亚新几内亚、所罗门群岛及新喀里多尼亚专属经济区内的珊瑚海海域持续开展数据采集。数据以.ENV和.DAT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）。本数据集共包含57个文件，原始数据总容量为463 MB。航次始末均使用Scintrex Autograv CG-5型重力仪开展码头联测：凯恩斯联测采用位于凯恩斯机场的参考站2008909952，布里斯班联测采用位于北岸滨河公园的参考站2016909147。码头联测数据存储于原始数据文件夹中的"Cairns_wharf_gravity_tie_in2019_v04.TXT"与"Brisbane_wharf_gravity_tie_post_in2019_v04.TXT"文件。本数据集未经过任何处理。有关本数据集的更多详细信息可参阅GSM数据采集与处理报告。
