Population dynamics of the intertidal limpet, Siphonaria diemenensis at Griffith Point, Victoria.

A combination of surveys and experiments were used to determine the size distribution, recruitment, mortality and growth rates of Siphonaria diemenensis in 2 zones on the rocky shore at Griffith Point, San Remo, Victoria. One zone was in the high intertidal (Zone 2) and one was in the low intertidal area on the shore. There were 3 sites in Zone 1 and 2 sites in Zone 2 (see parent record for more details). 
A size frequency distribution was constructed for each site from surveys that recorded the size of all individuals every 2 months from October 1979 to December 1981. In addition to the sites in Zone 1 there were 12 permanent quadrats (50 x 50cm) which were surveyed in the same manner from December 1980 to December 1981. The sizes of recruits were similar in both Zones but the sizes of adults were significantly greater in Zone 2. In both years, the maximum density of recruits in Zone 1 was greater than in Zone 2. The mortality rate of adult limpets in Zone 2 was lower compared to limpets in Zone 1.
The growth rates (mm per month) of marked individuals were calculated for 3 time intervals; January-March, March-May and May-late July (Zone 2) and Mary-early August (Zone 1) in 1981. Limpets in Zone 2 grew faster (average 0.63 mm per month) than the limpets in Zone 1 (average 0.11mm per month). 
In addition, an experiment was conducted in Zone 1 from May to July in 1981 to determine the effects of adult density and macroalgal cover on limpet recruitment. It was found that there was no effect of adult density but a significant interactive effect of algal cover and sampling date on the number of limpet recruits.

Background quality of the coastal marine waters off the west Kimberley coast.

A pilot survey of the quality of the coastal waters of the west Kimberley was undertaken in September and November 2008. Water quality samples were collected for ultra-trace metal analysis and for the determination of total suspended sediment concentrations. The objective of the survey was to estimate natural background concentrations of dissolved As, Al, Ag, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn and to gain some understanding of the range of typical suspended concentrations in the region.

Water quality measurements from the river plumes in the central Great Barrier Reef,  associated with Cyclone Sadie (1994)

On the 4th February, 1994, water samples were collected from 10 stations along an offshore transect between the Brook Islands and the Mulgrave River. Cyclone Sadie caused a large rain depression over most of the north Queensland catchment area and sampling took place two days after the main flood peak had occurred. Samples were collected hourly, while the research vessel was steaming. Surface samples were collected at six stations, using a bucket. At a further four stations, samples were collected at four depths using a series of three Niskin bottles spaced over a depth profile for subsurface samples and a bucket to collect the surface samples. In situ temperatures were recorded using digital reversing thermometers attached to the Niskin bottles.Samples were analysed for chlorophyll, suspended solids, dissolved inorganic and organic nutrients and salinity.Water transparency was measured using a secchi disk and the presence of Trichodesmium spp. noted visually. Additional data collected at each station were cloud cover, wind speed, wind direction, tide and acoustic depth.
 This research was undertaken to examine changes in water quality in a flood plume resulting from increased river runoff into the Great Barrier Reef lagoon.

IMOS - Ocean Radar - Direction finding ocean radar system (Seasonde)

Coastal ocean surface radar is a land-based technique which uses scattering from the rough sea surface to obtain echoes which are Doppler shifted by the dynamics of the sea.  It has been shown (Crombie, 1955) that the scatter is predominantly a Bragg interaction between the radio wave and the sea surface gravity wave that is propagating in the same direction and with half the wavelength of the radio wave.  This Bragg interaction gives two strong first-order lines in the echo spectrum; one from the resonant gravity wave moving radially away from the station, and one from the resonant gravity wave moving towards the station.
Direction-finding systems determine the azimuthal direction of a source point by comparing amplitude and phase signals on crossed loop receive antennas. The direction finding calculation is done on Doppler shift spectra for a specified range which includes return echoes from all azimuths.  This means that the spectra are spread and second-order echoes from one direction are swamped by the first-order echoes from other directions.  Consequently, parameter extraction using second-order echoes is not possible on a routine basis.  Directional wave spectra at the location of each radar station are produced by analysing the full azimuthal spread of first-order echo amplitudes, and wind directions are derived across the grid points by taking the ratio of the positive and negative Bragg echoes.
SeaSonde HF ocean radar stations are used on the Turquoise Coast (Seabird and Cervantes), Western Australia, and on the Bonney Coast (Nora Creina and Blackfellows Cave), South Australia.

Future Reef MAP - March 2013 (Northbound)

Data were collected as part of the FutureReef MAP project, a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef. The Future Reef MAP project is funded by Rio Tinto Alcan and administered by the Great Barrier Reef Foundation, with an equal co-investment by CSIRO. The project is the first large-scale CO2 observing system established on the Great Barrier Reef using the Rio Tinto ship, RTM Wakmatha. The research is targeted at providing information on the CO2 uptake and the controls on ocean acidification change in the region. It is providing foundation data needed to assess the vulnerability of the GBR reefs to ocean acidification. This dataset contains quality controlled underway measurements of the fugacity of CO2, atmospheric pressure, and sea surface temperature and salinity. The data management and distribution of these data were supported by the CSIRO Carbon Collaboration Cluster and the Australian Coastal Ecosystem Facility.

Coral recruitment surveys, Ningaloo Reef, Western Australia (WAMSI Node 3 Project 3.1.2)

The abundance of newly settled corals following the 2009 and 2010 annual coral spawning peaks was measured in the northern half of Ningaloo Reef at eleven locations between Coral Bay, Tantabiddi and Bundegi. An annual influx of coral recruits were detected at all locations, using terracotta tiles deployed by divers on the reef using permanent tile mounting fixtures, then subsequently retrieved and counted under a dissecting microscope.
 This study has measured annual coral recruitment rates at Ningaloo Reef using deployed tiles, but has also had a particular focus on evaluating some alternative methods for coral juvenile census. Deploying, recovering and assessing tiles is labor intensive, requires use of SCUBA and a specialist using a microscope in the laboratory for census of the tiles. A key aim of this project has been to understand the tradeoffs associated with simplified and more cost-effective approaches. The objective was to assess methods that could still yield robust research data, yet utilize non-specialist regional DEC staff for routine field surveys, maximizing the effectiveness of Perth-based specialist research staff for more complex analytical tasks.

IMOS - Animal Tracking Facility

The IMOS Animal Tracking Facility (formerly known as the Australian Animal Tracking And Monitoring System (AATAMS)) represents the higher biological monitoring of the marine environment for the IMOS program. Currently the facility uses acoustic technology, CTD satellite trackers and bio loggers to monitor coastal and oceanic movements of marine animals from the Australian mainland to the sub-Antarctic islands and as far south as the Antarctic continent. 
Acoustic monitoring is a powerful tool for observing tagged marine animals with networks or cross shelf arrays (curtains) of receivers, allowing animals to be monitored over scales of hundreds of metres to thousands of kilometres. An array or network consists of a series of acoustic receivers that are strategically deployed on the sea floor for 1 to 10 years (depending on receiver type and battery life) with the ability to download data from the receivers as often as required. NCRIS and partner investments will target areas identified by regional nodes. 
VR2's deployed in conjunction with other moorings will provide information on long range movement of a variety of species including endangered and protected species (i.e. White Sharks and Grey Nurse Sharks), and valuable commercial species (i.e. Tuna)
Curtains are mobile and can be deployed in different configurations for specific IMOS projects. The continued coordination of acoustic tag codes between researchers means that acoustic array around Australia will provide the combined infrastructure to monitor movement of highly migratory marine species between all jurisdictions.
CTD satellite trackers and bio loggers currently deployed on a large range of animals are collecting a wide range of data. This includes behavioural and physical data such as the depth, temperature, salinity and movement effort of individual marine animals. 
The Animal Tracking Facility is set up to collect data over a long period of time. This sustained approach will enable researchers to assess the effects of climate change, ocean acidification and other physical changes that affect animals within the marine environment.

Determining the ecological health of estuaries in North-Western Tasmania: Black River

This study considered a range of water-column and sediment (benthos) based variables commonly used to monitor estuaries,utilising estuaries on the North-West Coast of Tasmania (Duck, Montagu, Detention, and Black River). These included: salinity, dissolved oxygen, turbidity, nutrient and chlorophyll a levels for the water-column; and sediment redox, organic carbon content, chlorophyll a and macroinvertebrate community structure amongst the benthos. In addition to comparing reference with impacted estuaries, comparisons were also made across seasons, commensurate with seasonal changes in freshwater river input, and between regions within estuaries (upper and lower reaches) - previously identified in Hirst et al. (2005). This design enabled us to examine whether the detection of impacts (i.e. differences between reference and impacted systems) was contingent on the time and location of sampling or independent of these factors. The data represented by this record was collected in the Black River.

Summary of conventions, legislation affecting marine resource allocation, use, conservation and environmental protection on the North West Shelf

The Western Australian Department of Environmental Protection (WADEP) is conducting a $2.7M North West Shelf Marine Environmental Management Study (NWSMEMS) (the Study) over four years. The Study, which began in January 1998, is developing and consolidating the technical information base, scientific understanding and predictive capability required to underpin environmental decision making in both the public and private sectors. It is drawing on the support and involvement of the scientific, industry, community and State and Commonwealth government agencies through representations on a Steering Committee and Technical Group, the provision of data, direct contributions of research and consultations on a range of environmental issues. The ultimate outcome of the Study is to recommend options for a coordinated management framework under existing legislation and policies to ensure an integrated approach to sustainable development on the North West Shelf. This report compiles and summarises existing International Conventions and Treaties, Commonwealth and State legislation, policies, strategies and other instruments relevant to marine resource allocation, use, conservation and environmental protection on the North West Shelf. It identifies the agencies in which legislation is vested and the crossjurisdictional arrangements that are in place between Commonwealth and State agencies in implementing the legislation. The report will be used in at least two ways:  to ensure that there is a complete and accurate understanding of the existing legislative and management framework so that technical outputs of the Study provide the strategic and tactical information required to support the objectives of the existing management framework; and  to provide the basis for evaluating the effectiveness of the existing management framework and developing options to address any identified deficiencies.
