Brief description
The NRS Darwin mooring (IMOS platform code: NRSDAR), is one of 9 IMOS - ANMN National Reference Station (NRS) designed to monitor oceanographic phenomena in Australian coastal ocean waters. The NRSDAR buoy is deployed at Latitude: -12.3382, Longitude: 130.6952.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.
Lineage
Maintenance and Update Frequency: continualAt the Darwin national reference station, a mooring has been deployed with sensors for conductivity, temperature, depth, dissolved oxygen, photosynthetically active radiation (PAR), fluorescence and measurement of turbidity at two depths - near surface and near sea bed. At the seafloor, an Acoustic Doppler Current Profiler (ADCP) has been deployed. Reference stations telemeter a reduced data set via Iridium satellite or nextG for real time monitoring.
Physical sampling is undertaken at each of the reference stations on a monthly or quarterly basis. The physical samples are 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.
Scope Level Description: IMOS Sub-Facility platform level record
Current Magnitude data for Darwin were displayed during 2016-07-27 22:19:00+00 2022-05-11 23:39:00+00 with the units k/h and converted to m/s in 2023 to display consistently on the visualisation charts.
