Report on Wireless Sensor Network
Wireless Sensor Networks located on the Great Barrier Reef (GBR) collect real-time data at spatial and temporal scales required to understand complex marine processes, particularly those involving the interface between pelagic and benthic environments. Data from the local network is aggregated and streamed in real-time. This includes traditional oceanographic variables such as temperature and salinity but also video, imagery and above water parameters such as meteorological observations.
Wireless Sensor Networks were initially deployed at seven sites along the Great Barrier Reef, from Heron Island in the south to Lizard Island in the north. In 2014 there was a consolidation of sites, currently there are five sites in operation across the Great Barrier Reef. The IMOS work has been extended via other projects with an additional three sites being established in the Torres Straits; while these sites are not IMOS funded the data goes into the IMOS Oceans Portal.
All of the deployments were completed by 2010 although a number of Tropical Cyclones (Hamish, 2009, Yasi 2011, Ita 2014 and Nathan 2015) caused damage to some sites and while the damage has been repaired there are some data gaps as a result. The upside is that the sites have recorded detailed observations from each of the cyclones giving new insights to the impacts of these systems.
Four of the sites have been installed as part of the Tropical Marine Network of Island Research Stations with specialised access to data and the network available from these stations. These include the Heron Island Research Station (HIRS) on Heron Island operated by the University of Queensland, the One Tree Island Research Station (OTIRS) operated by Sydney University, the Orpheus Island Research Station (OIRS) operated by James Cook University and the Lizard Island Research Station (LIRS) operated by the Australian Museum. At each of the Stations a dedicated touch screen data display has been installed to facilitate local access to the real time data, the full set of data can be found on the Australian Ocean Data Network (AODN) Portal.
