Survey report 1998/99 summer season Voyage 4 Australian Antarctic Division Authors - R.Lemon / AUSLIG

Taken from sections of the report:IntroductionThis report details the survey work carried out on Voyage 4 during November and December 1998 by LANDINFO on behalf of the Australian Antarctic Division's MAGIP Field Program. The principle aim of this work was to acquire aerial photography of penguin rookeries near Australia's three Antarctic Stations and to carry out survey work associated with the Antarctic Tide Gauge Network. A number of other tasks were also carried out. This report details each task carried out and the results achieved. The following people carried out the survey work:Richard Lemon LANDINFO Pty LtdRoger Handsworth Antarctic Division Instrument EngineerThis report covers the fieldwork associated with the MAGIP Field Program. Some non survey aspects of the tide gauge work will be the subject of a separate report to be submitted by Roger Handsworth.Time FrameThe survey party departed Hobart at 5:15pm on Thursday 29th October 1998 aboard the Aurora Australis on Voyage 4 of the 1998-99 summer season. The survey party arrived at Casey Station via helicopter from the Aurora Australis just before 12pm (UTC+8) on Saturday 7th November. After spending a period of about 25 hours at Casey the survey team returned to the Aurora Australis at about 1pm on Sunday 8th November 1998. The Aurora Australis arrived off Davis Station on the morning of Wednesday 18th November 1998. The survey party had access to the station from about 2.30pm (UTC+7) the same day. The survey team had four full days in which to carry out its tasks at Davis. The Aurora Australis left Davis on the morning of Sunday 22nd November on route to Sansom Island. The survey party returned to the Aurora Australis by helicopter at about 7:30pm on Sunday 22nd November. The survey party was flown to Sansom Island at about 9:30am on Monday 23rd November and returned to the Aurora Australis at about 3:30pm the same day. Due to problems with Aurora Australis' propeller pitch control, the survey party was flown to Mawson Station by long range helicopter on Wednesday 2nd December and arrived at about 8:30am (UTC+6). The survey team had eight full days at Mawson station before departing for the Ship on Thursday 10th December at about 11am.The Aurora Australis returned to Fremantle at about 11am Western Standard Time (UTC+8) on Monday 28th December 1998.Project OutlineThe Antarctic Division's Brief, which outlines the details of the program, is included in Appendix A. The program of work was divided into four specific sites, Casey, Davis, Mawson and Sansom Island. The work at each of the Antarctic stations was divided into two main areas of interest. These being the aerial photography of the penguin rookeries using the Linhof camera and survey work associated with the tide gauges and tide gauge bench marks. The work at Sansom Island involved the coordination of photo control points.A list of the individual tasks and a summary of the achievements can be found at Appendix B.

本报告内容节选说明：引言
本报告详述了LANDINFO于1998年11月至12月期间，代表澳大利亚南极署（Australian Antarctic Division）的MAGIP野外项目（MAGIP Field Program）所开展的1998年第4航次勘测工作。本次工作的核心目标为：拍摄澳大利亚三座南极科考站附近的企鹅繁殖地航空影像，并完成与南极潮位站网相关的勘测任务，同时还开展了多项其他辅助工作。本报告将逐一详述本次执行的各项任务及取得的最终成果。参与本次勘测工作的人员如下：
理查德·莱蒙（Richard Lemon） LANDINFO私人有限公司
罗杰·汉兹沃思（Roger Handsworth） 澳大利亚南极署仪器工程师

本报告仅涵盖与MAGIP野外项目相关的野外作业内容，部分潮位勘测工作中非勘测类的技术细节，将由罗杰·汉兹沃思另行提交专项报告。

时间安排
勘测团队于1998年10月29日（周四）下午5时15分搭乘南极光号科考船（Aurora Australis）从霍巴特港出发，开启1998-1999夏季航次的第4航次。11月7日（周六）接近正午12时（东八区），勘测团队乘直升机从“南极光号”抵达凯西站。在凯西站停留约25小时后，勘测团队于1998年11月8日（周日）下午1时左右返回“南极光号”。
“南极光号”于1998年11月18日（周三）上午抵达戴维斯站附近海域，勘测团队于当日下午约2时30分（东七区）获得登站许可。勘测团队在戴维斯站拥有共计4个完整工作日开展既定作业。“南极光号”于11月22日（周日）上午驶离戴维斯站，前往桑瑟姆岛。勘测团队于当日下午约7时30分乘直升机返回“南极光号”。
11月23日（周一）上午约9时30分，勘测团队被空运至桑瑟姆岛，并于当日下午约3时30分返回“南极光号”。由于“南极光号”的螺旋桨变距控制系统出现故障，勘测团队于12月2日（周三）通过远程直升机被空运至莫森站，并于当日上午约8时30分（东六区）抵达。勘测团队在莫森站拥有共计8个完整工作日开展作业，随后于12月10日（周四）上午11时左右登船返程。
“南极光号”于1998年12月28日（周一）西澳大利亚标准时间（西八区）上午11时左右返回弗里曼特尔港。

项目概况
澳大利亚南极署的项目任务书（含本项目全部细节）已收录于附录A。本次工作划分为四个具体作业区域：凯西站、戴维斯站、莫森站及桑瑟姆岛。各南极科考站的作业分为两大核心方向：一是使用林哈夫相机（Linhof camera）拍摄企鹅繁殖地航空影像，二是开展与潮位仪及潮位基准点相关的勘测工作。桑瑟姆岛的作业内容为协调摄影控制点的布设与核验工作。
各项具体任务清单及成果汇总详见附录B。
