RV Investigator Voyage IN2021_E02 Gravity Data

This record describes gravity data collected on RV Investigator voyage IN2021_E02, to calibrate and commission new, upgraded and existing critical equipment (with sea trials and personnel training) onboard RV Investigator for upcoming voyages in the 2021 schedule and beyond. The primary objectives for this voyage were testing the Deep Corer winch stream and respool, Trawling winch calibration, CTD winch 1 & 2 calibrations, HOTS commissioning and Heave Compensation testing, and Deep Towed Camera trial and calibration. The voyage took place between November 20 and November 28, 2021, departing from Hobart (TAS) and returning to Hobart.

The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 20 files totalling 161 MB of raw data in this dataset. Wharf tie[s] were not undertaken.

No processing has been conducted on this data. There was an issue with the gravity meter part way through voyage and some 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IN2021_E02采集的重力数据，用于校准、调试该船搭载的新增、升级及现有关键设备（含海试与人员培训），以保障2021年既定航次及后续任务的顺利开展。本次航次的核心目标包括：深孔取样绞车缆绳与复绕测试、拖网绞车校准、CTD绞车1号与2号校准、HOTS系统调试与升沉补偿测试，以及深拖相机的试航与校准。本航次于2021年11月20日至11月28日开展，从塔斯马尼亚州霍巴特港启航并返回霍巴特港。

本次使用的重力仪为MicroG Lacoste Air-Sea II型。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（CSIRO）。本数据集共包含20个原始数据文件，总容量为161 MB，未开展码头联测作业。

本数据集尚未进行任何数据处理。航次进行过程中，重力仪曾出现故障，部分数据[原文未完整表述]。
