Surveys of green (no-take) zoned sites and blue (open to fishing) sites in adjacent areas of the northern Great Barrier Reef Marine Park were carried out to determine any effects which might be attributable to a change in zoning plan in 2004. Assessment of the fish communities was enumerated using baited underwater video sets (BRUVS) and towed video. \n \n'Cardwell shoals' comprised Brook Shoal (MNP-18-1077) as the site in the green zone; and Eva Rock and Forty Foot Rock as sites in in the "blue" zone in July, September and December 2006, November 2007 and May 2010.

A baseline survey of 5 green zoned sites on Magnetic Shoals together with 4 adjacent blue zoned areas of the marine park. Surveys were carried out in July, September, October and November 2006 to assess any seasonal effects on the fish and benthic communities in addition to potential zoning effects. The Shoals are characterised by a mosaic of rich epibenthic filter feeding communities typically surrounded by low relief algae and seagrasses. These communities appear to be founded on loose sediments comprised of sand, rubble and foraminifera.

Surveys were undertaken in January/February 2009 (summer) at the Capricorn-Bunker, Pompey and Swains Groups on deepwater reef bases (shoals) in the Great Barrier Reef. In each survey, reefs were paired with one zoned 'green' (closed to fishing) and the other 'blue' (open to all fishing) - 16 pairs of reefs. The demersal habitats and vertebrate communities were sampled using non-extractive baited remote underwater video stations (BRUVS), which revealed a diverse (c360 species) fauna of fish, sharks, rays and sea snakes.

During the central and eastern Torres Strait survey in November 2006, tissue samples of 10 individuals of the sponge Coscinoderma matthewsi were collected from 5 island groups: Ugar (Stephen Island) and Erub (Darnley Island) in eastern Torres Strait; and the Masig group (Kodall Island and Keats Island), Poruma (Coconut Island) and Warraber (Sue Island) in central Torres Strait. These island groups are on average, 66 km apart. All sponge samples were placed in separate cryo-tubes and preserved in liquid nitrogen until they could be stored at -80°C.

Size frequency surveys of the sponges Coscinoderma matthewsi, Hyrtios erecta and Ianthella basta (yellow color morph) were conducted at Masig Island, central Torres Strait, in March 2007. At each of eight sites, separated by at least 200 m, three randomly positioned 30 x 1 m transects were surveyed, with each transect separated by at least 20 m. All transects were located on sloping reef at between 10 and 12 m depth.The greatest dimension of each sponge was measured for Coscinoderma matthewsi and Ianthella basta, and used as an approximation of overall sponge size.

Surveys were undertaken in February/March 2007 (Autumn), August/September 2007 (Spring) and October 2009 (Spring) on two pairs of discrete deepwater shoals in the mid-shelf section of the southern Great Barrier Reef. The objective was to find pairs of shoals that were matched in terms of depth, habitat, areal extent, cross shelf position and latitude. Within each pair, one shoal was to be from a 'green zone' (closed to all fishing) and the other from a 'blue zone' (open to fishing), based on the rezoning of the Great Barrier Reef Marine Park, carried out in 2004.

This project conducted a biodiversity assessment of coral communities on Torres Strait reefs to establish a baseline of coral condition and start a longer-term monitoring program of selected coral reefs in the region. The monitoring looked for changes in the condition of coral reefs and documented factors that might contribute to changes including COTS, disease, bleaching, temperature anomalies etc. As part of this project, an early warning system was established for coral bleaching.

The coral, Acropora millepora and the crustose coralline algae, Neogoniolithon fosliei were exposed to 3 photosystem II (PSII) herbicides (diuron, hexazinone and atrazine). Corals were collected at depths between 1 and 3m from Double Cone Island and Hayman Island in the Whitsunday group. The crustose coralline algae was collected from Davies Reef at depths between 5 and 7m.

Using a quantitative genetics approach, the proportion of the variance in thermal tolerance traits that has a genetic basis (i.e. heritability) was estimated as a proxy for their adaptive potential in the widespread Indo-Pacific reef-building coral Acropora millepora. Two physiologically different populations that associate respectively with one thermotolerant (Symbiodinium clade D) and one less tolerant symbiont type (Symbiodinium C2) were chosen.

As part of MTSRF Task 2.5i.2, a range of indices were investigated to quantify upwelling on the central Great Barrier Reef (GBR), Australia. These indices are necessary for exploring environmental and biological relationships in areas where upwelling may be sporadic and less intense, especially along western boundary currents such as the East Australian Current.

Next generation DNA sequencing was used to scan a large proportion of the transcribed coding DNA in Acropora millepora for polymorphisms. Transcribed coding DNA (messenger RNA - mRNA) was extracted from 8 colonies sampled at three thermally distinct habitats along the GBR (Wilke Island Reef in Princess Charlotte Bay, Nelly Bay at Magnetic Island, and Miall Island in the Keppel Islands). The mRNA extractions from each population were pooled and translated back to the complementary DNA (cDNA), which was sequenced using 454 pyrosequencing by the Australian Genome Research Facility.

A three-dimensional whole-of-GBR baroclinic hydrodynamic model was applied at a spatial resolution of between 1 and 4 km. The model simulations are compiled to examine the intensity, duration and frequency of different lower salinity events. Return periods are then calculated from the annual frequency of such events. \n \nThe model includes the factors affecting currents, mixing, temperature and salinity within the GBR lagoon and exchanges with the adjacent Coral Sea: river discharge, time-series wind, tidal.
