RV Investigator Voyage IN2023_V01 Gravity Data

This record describes gravity data collected on RV Investigator voyage IN2023_V01, titled "Antarctic Bottom Water Production in the past: Records from marine sediments, Cape Darnley, East Antarctica". The voyage took place between 25th January, 2023 and 2nd March, 2023 departing from Henderson's (WA) and arriving in Hobart (TAS).The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 74 files totalling 582 MB of raw data in this dataset. Wharf ties were undertaken at Henderson_AMC Wharf and Hobart Wharf using a Scintrex Autograv CG-5. Wharf tie data can be found in gravity_data folder\Hobart_wharf_tie_2023_03_02.txt & Henderson_AMC_wharf_tie_2023_01_24.txt, which is stored with the raw data.No processing has been conducted on this data.Additional information regarding this dataset is contained in the GSM data acquisition and processing report.

本记录记述了搭载“调查号”（RV Investigator）执行航次IN2023_V01期间采集的重力数据，相关研究主题为《古代南极底层水生成：东南极洲达恩利角海洋沉积物记录》。本次航次于2023年1月25日至2023年3月2日期间执行，从西澳大利亚州亨德森港出发，最终抵达塔斯马尼亚州霍巴特港。本次作业采用的重力仪为MicroG Lacoste Air-Sea II型。数据以.ENV与.DAT格式文件存储于澳大利亚联邦科学与工业研究组织（CSIRO）。本数据集共计包含74个原始数据文件，总容量达582 MB。本次航次使用思凯创（Scintrex）Autograv CG-5型重力仪，在亨德森AMC码头与霍巴特码头开展了码头联测工作。码头联测数据存储于原始数据附带的gravity_data文件夹内，对应文件为Hobart_wharf_tie_2023_03_02.txt与Henderson_AMC_wharf_tie_2023_01_24.txt。本数据集未进行任何数据处理操作。本数据集的补充信息详见《GSM数据采集与处理报告》。
