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.
