Survey report from Macquarie Island 2024/2025

Summary of surveying work conducted on RSV Nuyina resupply Voyage 4 11 May – 7 June 2025. Surveys conducted:•    Completed GNSS survey control audit of the station including garden bay benchmarks•    GNSS survey of existing infrastructure building footprints and floor levels•    GNSS survey of infrastructure changes since 2024 survey – bunkhouse, temporary accommodation pods, combined instrument hut, existing fuel farm, gravel stockpile and stake out proposed new bulk fuel•    Levelling of tide gauges to permanent survey benchmarks in Garden Bay•    Terrestrial laser scanning of station buildings for mapping inside and out including incinerator, mess, science, biology and boat house •    Drone mounted LIDAR surveys of isthmus in three missions south, central and north for decision making for the new station for MISP•    Drone mounted LIDAR survey to collect data for land slip monitoring for Parks and MISP.•    Drone mounted LIDAR to map suitable drop zones for the delivery of cargo by plane•    Drone mounted LIDAR to map coastal erosion and future station site survey.•    Baseline line scans, installation and configuration of a landslip monitoring scanner for remote monitoring of North Head landslip areas.Concurrent to this scope of survey works, the Defence Science and Technology Group (DSTG) conducted operations with their medium lift Calisto 50 drone carrying a Riegl bathymetric lidar sensor to collect terrestrial and shallow water bathymetric data. This was also under the 5202 Mapping project.

2025年5月11日至6月7日RSV努伊纳号（RSV Nuyina）第四次补给航次勘测工作汇总。本次开展的勘测工作如下：
• 完成站区（含花园湾基准点）的全球导航卫星系统（Global Navigation Satellite System, GNSS）测量控制网审核工作
• 对现有基础设施建筑占地与地坪标高开展GNSS测量
• 针对2024年勘测以来的基础设施变更开展GNSS测量，涉及宿舍小屋、临时住宿舱、综合仪器棚、现有燃油库区、砂石料堆，并对拟建大型燃油库区进行放样测量
• 将验潮仪水准联测至花园湾的永久测量基准点
• 对站区建筑开展地面激光扫描，用于内外测绘，涵盖焚烧炉房、食堂、科研楼、生物实验室与船库
• 搭载激光雷达（Light Detection and Ranging, LIDAR）的无人机分南、中、北三个航次对地峡开展勘测，为MISP的新站建设提供决策支撑
• 搭载LIDAR的无人机开展勘测，为公园管理部门与MISP的滑坡监测采集数据
• 搭载LIDAR的无人机开展勘测，绘制飞机货运适宜空投区域地图
• 搭载LIDAR的无人机开展勘测，绘制海岸侵蚀区域图并开展新站址勘测
• 开展基线扫描，安装并配置滑坡监测扫描仪，用于北角滑坡区域的远程监测

同期，国防科学技术集团（Defence Science and Technology Group, DSTG）使用搭载Riegl水深激光雷达传感器的中型Calisto 50无人机开展作业，采集陆地与浅海水深数据，该作业同样隶属于5202测绘项目。
