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.

Sensor network infrastructure was installed at Davies Reef in the central Great Barrier Reef off Townsville, Australia. The infrastructure consists of a base station mounted on the existing reef communications tower and a number of buoys which carry the actual sensors. The initial design is to monitor the flow of water through the lagoon, the connectivity between the lagoon and the open ocean and the presence of an upwelling signal as oceanic water crosses the open shelf in the Townsville region. This site is linked to ones on the edge of the shelf (Myrmidon Reef) and sites closer in such as Rib Reef and Orpheus Island. The deployment in December 2009 consisted of the base station using the Telstra nextG service and five buoys or sensor floats. The sensor floats carry a mixture of sensors but typically a surface MEA Thermistor and a bottom mounted SeaBird SBE39 (temp + pressure), for some floats the SBE39 is replaced by a SBE37 to give salinity (as conductivity), temperature and presure. On the tower is a vaisala WXT520 weather station. The project looks to deploy sensor networks at seven sites along the Great Barrier Reef to measure a range of physical parameters at a range of scales. The project will install communications, data and platform infrastructure that will support future sensor work looking at biological and chemical parameters.

A round 1.4m yellow buoy has been deployed in the Heron Island lagoon as part of the sensor network infrastructure at Heron Island in the southern Great Barrier Reef off Gladstone, Australia. The buoy is configured as a sensor-float with a Campbell Scientific logger, a spread-spectrum radio for communicating with the on-reef wireless network, a GPS and initially a surface mounted (30cm under the water surface) thermistor.The float is moored in the lagoon of Heron Island in around 3m of water and will be used to monitor the flow of water through the lagoon. It will be fitted with surface salinity and bottom depth and temperature in late 2008. The unit will be serviced every six months and will be used in the future for attaching new sets of sensors. The buoy is re-locatable and the GPS data should be used to find the current location. The buoy is one of five re-locatable platforms in the lagoon at Heron Island onto which sensor will be located. The buoys initially have a Campbell Scientific loggers powered off two 5W solar panels, a Garmin GPS unit and one thermistor located at the base of the buoy around 30cm below the water line. The buoys use a Campbell Scientific spread-spectrum radio to talk back to the base station located on Heron Island.

A series of 6m steel poles have been installed in the lagoon of Heron Island as part of the sensor network deployment at Heron Island. The poles serve two purposes; their primary purpose is to form the backbone of a wireless network that covers the entire lagoon system and secondly they themselves support a range of sensors mounted onto the pole or leading away from the pole. One pole (RP5) also supports a Vaisala WXT520 weather station.This record is for Sensor Relay Pole 8. The pole is solar powered and routes data from the Sensor Floats and other Sensor Relay Poles back to the Base Station located on Heron Island. The system uses the Campbell Scientific CR1000 loggers and RF411 Spread-Spectrum radios to process and route the data. The poles also can support a range of sensors.The unit will be serviced every six months and will be used in the future for attaching new sets of sensors. The pole works primarily as a network repeater, it collects data from other poles and the Sensor Floats and routes it back to the Base Station either directly or via another pole. The poles are spaced approximately every two kilometers with the exception of those closest to the island, the base station on the island is on a 19 m tower and so a greater range was found for the first set of poles.Each pole therefore provides a wireless data network in a two kilometer radius, the combination of the poles provides coverage for the entire lagoon. The height of the base station gives around a five kilometre range around the island itself.The poles are 6 m in height constructed from galvanized steel with a solar powered instrument top consisting of a battery unit powered from the solar panels, Campbell CR1000 logger and Campbell RF411 radio. The logger can support a range of interfaces and is suitable for connection to a range of instruments.

The base station for the sensor network is located on water tank tower at the Orpheus Island Research Station run by the University of Sydney. The base station collects data from the outlying sensor stations (RP1-RP3) within the lagoon of One Tree Island as well as having a LiCor 192 PAR sensor.The base station consists of a Campbell Scientific CR1000 logger that talks back to the mainland via a 5m mast located on the top of the tower and a Cybertec nextG modem, and to the rest of the equipment in the lagoon via a 900 MHz spread-spectrum Campbell RF411 radio.The station is powered off the research station power supply but has its own solar panel and battery supply in case of power outages. The base station collects and syncronises data with the three monitoring stations (RP1 to RP3) within the lagoon of One Tree Reef and sends the data back to the mainland via a Telstra nextG connection. The station also has a light (PAR) sensor and potentially can have other sensors connected.

A Vaisala WXT520 integrated weather station has been installed on RP2, a 6m steel pole which has been installed within the lagoon of Lizard Island on the northern Great Barrier Reef. The sensor-relay pole provides a platform for the installation of sensors to measure and monitor water conditions within the lagoon of Lizard Island. The pole has real time communications using 900MHz spread spectrum radio back to a base station on Lizard Island.The weather station provides measurement of air temperature (Deg. C.), humidity as relative percent, barometric pressure (milliBars or hPa), rainfall amount, intensity and duration, hail amount, intensity and duration (not common on coral reefs!) and wind speed and direction. The wind speed and direction and processed into scalar and vector (directional) based readings and presented as 10 and 30 minute averages to give mean values and maximum values. From these you can get the average wind conditions at either 10 minute or 30 minute periods as well as the gust or maximum wind conditions.The weather station is connected via an SDI-12 interface to a Campbell Scientific CR1000 logger which uses a RF411 radio to transmit the data, every 10 minutes, to the base station on Lizard Island and then a Telstra nextG link is used to send the data back to AIMS.Identical weather stations are also on Heron Island (southern GBR), One Tree Island (near by) and Orpheus Island (central GBR). A light sensor is also located on the Island itself to give measures of PAR. The weather station is to provide on-reef weather conditions to allow the interaction with the atmosphere and the water to be understood. It is NOT set up as a meteorological grade station (for example it is too low to the water) but rather to give an indication of the atmospheric conditions at the surface of the water actually on the reef. If you need meteorological grade observations then use the data available for near by locations from www.bom.gov.au Power SupplyBattery Backed (1 x 33Ahr AGM with Solar Regulator), 4 x 5W Solar Panel Supply.Logger Settings - Pakbus Address - 150Logger Setup as router (isRouter = True)SDC7 comms board rate set at 34KSDC7 neighbours range: 1 - 180SDC7 Beacon: 3600Over-Reef RF Network - RF411 attached to the CSIO port of the loggerRadio Settings - Active Interface - Datalogger CSDCSDC Address 7Protocol: Pakbus awareRadio Net Address - 0Hop Sequence - 0Power mode - Retry level - Low

Five sites within Cleveland Bay were instrumented with Wetlabs NTU (turbidity), LiCor PAR (light as PAR) and Diver CTD instruments with monthly data download and collection of water samples for TSS analysis. Instruments were deployed in September 2014 and removed in August 2017 under a contract with the Port of Townsville Limited (PoTL).The work was to understand background and dredging turbidity within the bay. Sites were located in the eastern part of the Bay (JCU Seagrass Watch site 'Meadow-19' = Site CB), at Florence (Site FB), Geoffrey (Site GB) and Picnic Bays (Site PB) around magnetic Island and at Virago Shoals (Site VS) off Pallarenda.Data from the Cleveland Bay AIMS weather station were also provided along with MMP data for Picnic Bay. To monitor background levels of turbidity (as NTU and underwater light) in the Bay and to provide information on potential impacts of maintenance dredging on turbidity levels at sensitive receptor sites (Coral Reefs - Florence, Geoffrey and Picnic Bays, Seagrass - Virago Shoals and Meadow-19). Data was collected from September 2014 through to August 2017,
