Determining main carbonate mineralogy, and the primary components of the non carbonate fraction, at three depths in core GC11, collected from the Capricorn Channel.

A gravity core (GC11) was collected from a depth of 502 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Analysis of other parameters revealed the Last Glacial Maximum (LGM) sitting at a depth of ~30cm into the core. Three samples were collected for XRD analysis; at the sediment surface (GC11-0) representing interglacial sediment, at 260cm (GC11-260) also representing interglacial sediment, and from 160cm (GC11-160) - representing glacial sediment. XRD analysis shows that the majority of the interglacial sample (GC11-260) carbonate is made up of calcite. The glacial sample (GC11-160) is only 50% CaCO3 with the rest of the sample made up of quartz and clays.

Cross shelf variation in assemblages of Lutjanidae and Lethrinidae in the central Great Barrier Reef

In March 1993, fish traps were deployed on three reefs located across the continental shelf in the central Great Barrier Reef. One reef was nearshore (Pandora Reef), approximately 10 km from the coast; one on the midshelf (Rib Reef), approximately 50 km offshore; and one on the outershelf (Myrmidon), approximately 100 km offshore.Traps were deployed day and night on the protected leeward slopes of the midshelf and outershelf reefs in depths of 15-40 m, and on the leeward slopes of the nearshore reef in depths of 10-15 m (maximum depth of nearshore reefs). Traps were set in a random manner, at a minimum distance of 50 metres apart and ranged up to a few hundred metres apart in order to reduce possible overlap in the capture fields of adjacent traps. A total of 48 trap sets (2 days, 2 nights of sampling with 12 traps) were completed on the outershelf, 24 trap sets (1 day, 1 night of sampling) were completed on the midshelf and 36 trap sets (1 day, 2 nights of sampling) were completed inshore.'Day' set traps were set between 05:30 h and 08:30 h and were hauled from 16:30 h onwards, with sorting and processing usually completed by 18:30 h. Soak times during the day varied from 9 to 11 h. 'Night' set traps were set between 16:30 h and 18:30 h, left overnight and were hauled from 05:30 h onwards, with sorting and processing of trap catches usually completed by 08:30 h. 'Night' soak times varied from 12 to 14 h.The catch of each trap was identified to species, measured to the nearest millimetre, then tagged and released.
 This study was undertaken to examine and quantify the distribution and abundance of species of the Lutjanidae (snappers) and Lethrinidae (emperors), given the extremely variable physical environmental conditions occurring across the continental shelf in the central Great Barrier Reef region.

Redmap (Victoria) - Sightings of Reptilian Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.
Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.
The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.
This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please see Point of Contact.

Analysis of porewater extracted from coral heads from the central Great Barrier Reef

In March 1981, colonies (heads) of the massive coral, Porites lobata, were collected using SCUBA from Davies Reef and Britomart Reef, for analysis of the porewater within the coral skeletons. Coral heads, 15-30cm in diameter, were broken off, brought near the surface and transferred into large polyethylene tubs before being transferred onto a boat. Within 15 minutes to 2 hours of collection, the coral heads were taken out of the tubs and cleaved open. The living tissue and the band of endolithic algae were removed from the upper surface and blocks of about 1 litre in volume were removed from the head. All further handling of the coral blocks and porewater was carried out under nitrogen. Each block was placed inside a centrifuge designed to extract porewater. pH and dissolved oxygen concentration of the porewater were determined immediately after collection. The porewater was then transferred to acid-washed polypropylene bottles and frozen for nutrient analyses (phosphate, nitrate, nitrite, ammonia and silicate).Control blocks were prepared a month in advance by extracting blocks from coral heads, soaking them for a week in concentrated hydrogen peroxide, then immersing the blocks for a week in running seawater. Control water samples for analyses were obtained by soaking the blocks in ambient seawater for 2 hours and extracting the porewater as previously described. Ambient seawater samples were also collected and analysed.
 This study was initiated to determine whether the water in the interior of coral heads differed from the surrounding seawater and to investigate if evidence exists for nutrient regeneration and microbial respiration within the coral skeleton.

Current meter and tide gauge data obtained from an off-shore mooring near Jervis Bay: 05/04/89 - 07/12/89

A current meter mooring was installed in 100m of water, approximately 2km offshore of Point Perpendicular, Jervis Bay. This mooring housed 3 current meters (at 30m, 55m and 90m water depth) and also a tide gauge. Over a period of approx. 8 months the mooring was deployed 3 times in nominally the same location (as illustrated). Deployment 1 - 35.16 S, 150.817 E. 
Deployments 2 &amp; 3 - 35.1267 S, 150.825 E. Datasets presented here correspond to data retrieved from the three current meters over the study period.
The hourly datasets provide data accumulated from all 3 deployments, and provide details of the eastern &amp; northern tidal components, cross &amp; long-shore velocity components, temperature, salinity and sigma-T.
The subsets to these larger datasets present individual data points collected at sample intervals of 10 mins (deployment 1) or 15 mins (deployments 2 &amp; 3) for the upper two meters at 30m and 55m water depth. The current meter at 90m utilised sampling intervals of 10mins (deployments 1 &amp; 2) and 30mins (deployment 3). Compared to the hourly averaged datasets, these allow water movements to be studied over a shorter time scale. The parameters measured include the eastern and northern tidal components, water speed and direction, temperature, salinity and sigma-T.
Approx deployment dates - see individual records for exact date and time of collection: 1) 11/4/89 - 5/6/89... 2) 28/7/89 - 29/8/89... 3) 30/8/89 - 29/11/89
TIDE GAUGE: The tide gauge was secured to the mooring line on the sea-bed at a depth of ~100m for all three deployments  In addition to depth, the tide gauge also housed a temperature sensor.

Theme 2D: Development of new methodologies for measurement of anthropogenic disturbances.

Urban cities generate considerable potential for ecological disturbance leading to environmental degradation (Programme 2: Anthropogenic Disturbances of Coastal Habitats). In particular, there are problems for organisms on hard and soft substrata because of building jetties, seawalls, pilings, etc. Human disturbances include foraging for bait and food and disposal of wastes. The research to understand ecological changes due to these disturbances is time-consuming and long-term, particularly when experimental analyses of processes during disturbances are planned.
Predicting, measuring and interpreting impacts are hamstrung by poor sampling and analysis - often dictated by inadequate statutory requirements for Environmental Impact Statements. One major problem is that natural ecological assemblages of species vary enormously from time to time and place to place. Thus, even when undisturbed by people, ecological patterns are very different from place to place and change rapidly from time to time. 
All assessments of impacts are made difficult by large natural variations in space and time in the number of animals and plants. Against this very complex natural background, it is important to be able to design appropriate sampling and statistical procedures for reliable detection of unnatural change. Particularly important have been analyses of complex impacts through time, the consequences of impacts acting at different and unpredictable spatial scales and the power of sampling programmes, i.e. their likelihood of finding an impact of a particular size. 
The Centre for Research on Ecological Impacts of Coastal Cities (EICC) has generated many scientific papers and theses from research projects on    numerous new and modified sampling designs and analytical procedures to help detect and measure impacts.

Integrated Marine Observing System (IMOS) - Location of assets

IMOS is designed to be a fully-integrated, national system, observing at ocean-basin and regional scales, and covering physical, chemical and biological variables. IMOS observations are carried out by 10 national Facilities, each deploying a particular type of observing platform: Argo Floats, Ships of opportunity, Deep-water moorings, Ocean Gliders, Autonomous underwater vehicles, Coastal moorings, Coastal ocean radars, Animal tracking and monitoring, Wireless sensor networks, and Satellite remote sensing. IMOS Facilities, operated by partner institutions around the country, are funded to deploy equipment and deliver data streams for use by the entire Australian marine and climate science community and its international collaborators.
The IMOS Ocean Portal (http://imos.aodn.org.au) allows marine and climate scientists and other users to discover and explore data streams coming from all of the Facilities – some in near-real time, and all as delayed-mode, quality-controlled data. 
IMOS is supported by the Australian Government and is led by the University of Tasmania on behalf of the Australian marine and climate science community.
This record provides a visualisation of all IMOS assets, from its ten facilities.

Human activity and its effects on marine intertidal plant and animal populations: monitoring and management

This thesis examines the relationships between human use and biological changes in the rocky intertidal zone of the Bunurong Marine Park, Victoria  between January 1990 and June 1991. The key areas of activities were to i) describe the  types and patterns of human activities on the reef,  ii) assess the impact  and recovery of reef biota to these activities with particular focus on Hormosira banksii, the dominant algal community and  iii) determine the natural fluctuations in reef communities to provide a baseline to detect future changes in response to protection.
Surveys of human activities between January 1990 and April 1991 found walking to be the most common activity.  Levels of human use were greatest during school holidays followed by weekends and were lowest during term weekdays.  During school holidays use varied with the time of day and use on term weekend depended on weather.  
The impact of collecting intertidal gastropods and trampling were investigated.  There was no relationship between the observed patterns of human use and variations in the size distributions of collected and non-collected intertidal gastropods.  Experimental trampling showed that the dominant alga on these reefs, Hormosira banksii, was severely affected by trampling.  The cover of Hormosira was reduced by trampling and the decrease in cover depended on the level of trampling.  No significant effects of trampling were detected for any other species.   Trampled beds of Hormosirra banksii took well over a year to recover to the same level as adjacent mats. 
Algal monitoring showed that the cover of Hormosira was stable over time, except for a large decrease due to desiccation in summer.  These findings are discussed in relation to the management of the Bunurong Marine National Park.
