Introduction

AIMS operates the Queensland and Northern Australia Moorings sub-facility of the IMOS Australian National Mooring Network. The array is located in the northern tropics along the Great Barrier Reef for Q-IMOS in the east and in the north western parts of Australia for the WAIMOS nodes. The mooring arrays provide near real time and delayed mode observations from oceanographic moorings comprising physical (temperature, salinity, sea level and currents) and water quality measurements (turbidity, fluorescence, dissolved oxygen).

This deployment web page is provided to assist users to discover what, when and where instruments have been deployed. Locations, mooring diagrams, instrument setups and filenames are provided. Over time we will make summary plots and photos of sensors post deployment available. The data itself is to be accessed through the AODN data portal via www.imos.org.au. Links to the data are also available in these pages for each instrument.

The Queensland node of Australia's Integrated Marine Observing System - Q-IMOS - was established in 2007 along the GBR and extends an earlier long term observing programme. The Q-IMOS GBR array is located along the outer Great Barrier Reef in order to monitor the Western Boundary currents of the Coral Sea comprising the poleward East Australian Current and the equatorward Gulf of Papua Current. Four mooring pairs consist of a continental slope mooring in 70 to 300m of water and its partner on the outer continental shelf within the reef matrix in depths of 30 to 70m. The array is designed to detect any changes in circulation, temperature response, mixed layer depth and ocean-shelf exchanges.

North west WAIMOS observations commenced in June 2010 with the roll out of 4 moorings from Joseph Bonaparte Gulf to the Timor Slope. These continental shelf moorings complement a deep water array monitoring the Indonesian Throughflow in the Timor Trough and Ombai Strait and are operated by CSIRO. In early 2012 two more arrays were added off the Kimberley and Pilbara continental shelf regions. The arrays aim to monitor boundary currents such as the Holloway and Leeuwin Currents. Cross-shelf exchanges are also observed in these high energy macro-tidal and internal wave dominated shelves.

Three of the 9 National Reference Stations are also operated by AIMS at Ningaloo (withdrawn August 2014) and 2 near real-time moorings near Darwin and the Yongala Wreck in the lagoon of the GBR.

The Beagle Gulf mooring extends seaward oceanographic observations from Darwin Harbour and complements the National Reference Station located at Channel Marker Buoy#5. The mooring was upgraded to near real time in September 2014. Channel marker number 5 was removed in February 2015, resulting in the mooring being moved to Channel marker 1. The marine observing systems deliver the information needed to support the development and operational management of ports and harbours. Most ports and harbours are multi-use regions supporting industry and recreational activities, and observing systems play an important role in both port operations, and in generating understanding of processes that impact the sustainable use and development of these areas (e.g. sediment transport, water quality). Water current profiles and wave measurements will directly assist shipping operations and feed into a model that seeks to evaluate impacts on the health of the harbour.

IMOS is an Australian Government initiative established under the National Collaborative Research Infrastructure Strategy and the Super Science Initiative and supported by Queensland and Western Australian State Governments.

The following moorings have been withdrawn, pending further funding:
