Data

Your access to IMOS Queensland and Northern Australian Mooring data discovery and exploration is through the  Australian Ocean Data Network (AODN) Portal.

An array of nine moorings along the Great Barrier Reef is designed to monitor the flow of oceanic water along and into the reef matrix. Most of these moorings are delayed mode and data is recovered when the moorings are serviced every six months. However, the Yongala National Reference Station (NRS) and Palm Passage mooring operate in near real time and data is displayed and accessed via the World Wide Web. This infrastructure in the central GBR has application to a wide variety of users. The coastal Yongala NRS and off-shore Palm Passage moorings are located close to shipping lanes and could be used to better assess environmental conditions to support operational management of shipping in this region of GBR World Heritage Area. The advent of near real time observations and higher resolution 3-D operational models of the ocean environment, such as eReefs, are providing the opportunity to access timely information to better inform decision making by managers, use by industry and the general public. eReefs is a collaborative project contributing to the protection and preservation of the Great Barrier Reef utilising measured data and model output from the catchments, estuaries and oceans to better understand the health of the Great Barrier Reef, and it’s response to emerging threats and events (Steinberg et al., 2013).

With the establishment of the Darwin NRS information for the harbour on currents, tides, waves, wind and some water quality variables (Chl-a and turbidity) are now available in near real time. The real-time mooring observations are enabling a better understanding of factors affecting Darwin harbor such as tides, currents, wave height and movement of sediment, with sensors on the reference station providing data on over 30 parameters every 30 minutes which are of great benefit to the operations of the port of Darwin. The station measures tidal currents, waves, chlorophyll-a, turbidity, wind vectors, temperature and rainfall and the system is telemetered with the data available in near real time. It is currently being used to provide boundary conditions for a numerical model of the harbour as well as provide data to mariners for ship handling. The addition of a second mooring in the Beagle Gulf will expand our understanding of the factors influencing coastal systems and serve as an early warning system. It will provide alerts of approaching weather and allow forecasting of waves and current at key sites along the shipping channel. Accurate, real-time data about harbour and ocean conditions allows models to predict the weather in shipping channels. A real-time stream of weather data from the Darwin NRS can be accessed in various formats that include mobile devices.
