Brief description The Australian National Mooring Network Facility is a series of national reference stations and regional moorings designed to monitor particular oceanographic phenomena in Australian coastal ocean waters.
There are seven sub-facilities in the ANMN: four regional sub-facilities, a series of National Reference Stations (NRS), Acoustic Observatories and an Acidification Moorings sub-facility.
The ANMN sub-facilities are:
a) Queensland and Northern Australia
b) New South Wales
c) Southern Australia
d) Western Australia
e) Acoustic Observatories
f) National Reference Stations (Coordination and Analysis)
g) Acidification Moorings
The National Reference Stations were first established in the 1940’s and are the backbone component of the observing system. Extended by IMOS from three to nine sites around the entire Australian continent, the stations report integrated biological, chemical and physical oceanography time series observations, upon which more intensive local and regional scale studies can be referenced against. The regional moorings monitor the interaction between boundary currents and shelf water masses and their consequent impact upon ocean productivity (e.g. Perth Canyon Upwelling; Kangaroo Island Upwelling) and ecosystem distribution and resilience (e.g. Coral Sea interaction with the Great Barrier Reef ). Operation of the network is distributed between several operators and coordinated nationally.
Passive acoustic listening station arrays are located at three sites. These stations provide baseline data on ambient oceanic noise, detection of fish and mammal vocalizations and detection of underwater events. The Acidification Moorings are co-located at three of the National Reference Stations, and provide key observations to help us understand and address the problem of increasing ocean acidification.
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.
