The NRS Kangaroo Island Mooring (IMOS platform code: NRSKAI) is one of a series of National Reference Stations designed to monitor particular oceanographic phenomena in Australian coastal ocean waters. The mooring is located at Latitude:-35.83. Longitude:136.447.
Sensor data are collected at the mooring using an NXIC Conductivity Temperature Pressure (CTD) by Falmouth Scientific, a Workhorse Acoustic Doppler Current Profiler (ADCP) by Teledyne RDI and a Water Quality Monitor (WQM) by WETLabs. Parameters measured include temperature, pressure, salinity, chlorophyll concentration and turbidity.
Sensor data are available in quality controlled NetCDF format from the IMOS OPeNDAP server.
Biogeochemical data are also available.
Maintenance and Update Frequency: continual
Statement: NATIONAL REFERENCE STATIONS
The IMOS national reference stations will extend the number of long term time series observations in Australian coastal waters in terms of variables recorded both in their temporal distribution and geographical extent. It will also provide for biological, physical and chemical sampling and for 'ground truth' of remotely sensed observations. Currently there are only 3 long term reference stations and these would be extended to 9 distributed around the continent.
At each coastal reference station a mooring will be deployed with sensors for conductivity, temperature, depth, fluorescence, dissolved oxygen, photo-synthetically available radiation (PAR), fluorescence and measurement of turbidity at three depths - the surface, seabed and an intermediate depth. At the seafloor Acoustic Doppler Current Profilers (ADCP) will be deployed. All reference stations will telemeter a reduced data set via Iridium satellite for real time monitoring.
Physical sampling will be undertaken at each of the reference stations on a monthly basis. The physical samples will be analysed for nutrients, plankton species, both visibly and genetically, and pCO2. Biological sampling will greatly improve Australia's capability to meet its obligations for ecosystem based management and allow many researchers the opportunity to investigate possible long term changes in ecology that are likely to be linked to climate variability and wide scale validation of remotely sensed (satellite) observations of plant biomass.
Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent.
