Melville Bay Nhulunbuy Export Wharf Tide Guage

To assist with navigation planning, a tide gauge was re-established using the existing enclosure and well casing on the Export Wharf in Gove Harbour, at the site of the previous tide gauge discontinued by the NT Government in 2007. The tide gauge consists of a float activated absolute shaft encoder linked to a digital data logger and a nextG modem. The tide gauge logs water level (above lowest astronomical tide) at 10 minute intervals and transmits in near real-time to AIMS where it is stored, backed up and made available for display and download.

为辅助导航规划工作，科研人员于戈夫港（Gove Harbour）出口码头的原潮位计（tide gauge）旧址处，依托现存围护结构与井套管复建了一座潮位计；该旧址为2007年被北领地政府（NT Government）停用的原有潮位计布设点位。该潮位计由浮子驱动式绝对轴编码器（float activated absolute shaft encoder）、数字数据记录仪（digital data logger）与nextG调制解调器连接组成，以10分钟为间隔记录相对于最低天文潮面的水位高度，并近乎实时地将数据传输至澳大利亚海洋科学研究所（Australian Institute of Marine Science，AIMS），数据将在该机构完成存储、备份，并开放展示与下载权限。
