RV Investigator Voyage IN2022_V08 Gravity Data

This record describes gravity data collected on RV Investigator voyage IN2022_V08, titled "Biodiversity Assessment of Australia’s Indian Ocean Territories", which departed Darwin on September 30 and returned to Fremantle on November 3, 2022. This was a continuation of voyage IN2021_v04.The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 36 files totalling 576 MB of raw data in this dataset. A wharf tie was undertaken at the end of the voyage at Henderson Wharf (in Fremantle) upon vessel arrival using a Scintrex Autograv CG-5. No wharf could be undertaken in Darwin due to personnel restrictions. Note: Due to a Time Server issue on the Gravity PC, data from Julian days 273-297 (i.e. 30th September to 24th October 2022) had to be time corrected, and those files can be found in the "time_corrected" folder which is stored with the raw data. Wharf tie data can be found in "Henderson_wharf_tie_2022_11_03.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.

本记录描述了“调查号”研究船（RV Investigator）IN2022_V08航次采集的重力数据，该航次主题为“澳大利亚印度洋领地生物多样性评估”，于2022年9月30日从达尔文港启航，同年11月3日返回弗里曼特尔港。本航次为IN2021_v04航次的延续。本次使用的重力仪为MicroG Lacoste Air-Sea II型。数据以.ENV和.DAT格式文件存储于澳大利亚联邦科学与工业研究组织（CSIRO）。本数据集共包含36个原始数据文件，总容量达576 MB。航次结束后，船舶抵达弗里曼特尔亨德森码头时，使用Scintrex Autograv CG-5型仪器完成了码头联测。因人员限制，达尔文港未开展码头联测工作。备注：由于重力仪配套计算机的时间服务器故障，儒略日273至297（对应2022年9月30日至10月24日）的原始数据需进行时间校正，校正后的数据文件存储于原始数据配套的"time_corrected"文件夹内。码头联测数据存储于原始数据配套的"Henderson_wharf_tie_2022_11_03.TXT"文件中。本数据集未进行任何数据处理操作。有关本数据集的补充信息详见GSM数据采集与处理报告。
