Surveys on Macquarie Island for the Australian Antarctic Division, September to November 1997

Natasha Adams, surveyor, carried out surveys on Macquarie Island for the Australian Antarctic Division between September and November 1997.\r\n\r\nA number of science programs required survey assistance on Macquarie Island. \r\n\r\nFour major tasks were to be performed during the period of 13 September to 24 November 1997. These, in order of priority were\r\n\r\n1 ASAC Project 2277: Track monitoring and assessment - location of tracks and monitoring of vegetation type and degradation in conjunction with Judith Urquhart\r\n\r\n2 ASAC Project 1015: Location of botanical transects on four mountains for Craig Tweedie\r\n\r\n3 Location of points of interest for Clive Crossley\r\n\r\n4 Second order levelling between the Garden Cove Tide Gauges and the AFN site AUS211 \r\n\r\nThree other tasks were also undertaken in spare time whilst on the island\r\n\r\n1 Location of Geological sites for Garry Davidson\r\n\r\n2 Location of Royal Penguin Rookery boundaries at Sandy Bay and Bauer Bay for Mark Hindell\r\n\r\n3 Location and heights of the named mountain tops on the island for AUSLIG \r\n\r\n \r\n\r\nInformation about the survey and data are provided in two reports:\r\n\r\nN. Adams, 'Survey Report for Macquarie Island, September to November 1997' and M. King, R. Coleman and P. Standen, 'GPS data processing, Macquarie Island, September to November 1997'.\r\n\r\nAvailable for download from the URLs below are:\r\n\r\n(i) The differentially corrected point data from the walking track survey, as a spreadsheet.\r\n\r\nAttributes include surface, disturbance indicators, drainage and gradient.\r\n\r\n(ii) Vegetation along the walking tracks (points) extracted from the differentially corrected point data, as a shapefile. \r\n\r\n(ii) Walking tracks (lines) generated from the differentially corrected point data, as a shapefile. \r\n\r\n(iii) Natasha's survey report as a pdf.\r\n\r\nThe walking tracks are displayed in a pair of A3 1:50000 maps produced by the Australian Antarctic Data Centre. \r\n\r\nA map list in the URLs below allows access to the Map Catalogue entries for these maps from which the maps can be viewed or downloaded as pdfs.

测量师娜塔莎·亚当斯（Natasha Adams）于1997年9月至11月期间，为澳大利亚南极局（Australian Antarctic Division）开展了麦夸里岛（Macquarie Island）勘测工作。

多项科学项目在麦夸里岛开展时均需勘测协助。

1997年9月13日至11月24日期间，需完成四项核心任务，按优先级排序如下：

1. ASAC项目2277：步道监测与评估——与朱迪思·厄克特（Judith Urquhart）协作，确定步道位置并监测植被类型与退化情况。
2. ASAC项目1015：为克雷格·特威迪（Craig Tweedie）确定四座山体上的植物样带位置。
3. 为克莱夫·克罗斯利（Clive Crossley）确定感兴趣点位的位置。
4. 在花园湾验潮站（Garden Cove Tide Gauges）与AFN站点AUS211之间开展二等水准测量。

驻岛期间还利用空余时间完成了三项额外任务：

1. 为加里·戴维森（Garry Davidson）确定地质点位位置。
2. 为马克·欣德尔（Mark Hindell）确定桑迪湾（Sandy Bay）与鲍尔湾（Bauer Bay）的皇家企鹅繁殖地边界。
3. 为澳大利亚大地测量局（AUSLIG）确定岛上已命名山顶的位置与海拔高度。

本次勘测相关信息与数据收录于两份报告中：

N.亚当斯所著《1997年9月至11月麦夸里岛勘测报告》，以及M.金、R.科尔曼与P.斯坦登所著《1997年9月至11月麦夸里岛GPS数据处理报告》。
