“…Even in dense reef areas of the GBR (i.e., areas with a large ratio of reef area to the area between the reefs), such as the Swains reefs, an inflow from the adjacent Coral Sea can be traced. In this paper we have only presented two examples of extensive intrusion in the GBR but such intrusions had already been reported in the literature [Burrage et al, 1996;Brinkman et al, 2002]. More work is needed using satellite imagery to analyze the frequency of these intrusions, however the data presented here support the proposition that, on occasions, very large water exchange events occur.…”

“…North of the Queensland Plateau, a deep basin extends with depths varying between 3000 to 5000 m, which contrasts with shallow areas of the Queensland Plateau with depths shallower than 500 m and with the GBR shelf. The GBR, in particular, extends for more than 2000 km, from Papua New Guinea to Fraser Island in southern Queensland, and comprises over 2500 reefs and islands [Webb, 2000;Brinkman et al, 2002;Luick et al, 2007;Qiu et al, 2009].…”

“…The black box represents the limit of our domain of study, the western Coral Sea. enters the Coral Sea (Figure 2), it encounters an arc of islands (Fiji, Vanuatu and New Caledonia) that greatly impedes the broad westward flow, resulting in five strong and narrow jets [Webb, 2000;Brinkman et al, 2002;Luick et al, 2007;Qiu et al, 2009]. Of these jets, two enter the Coral Sea, between the Solomon Islands and New Caledonia, the north Vanuatu jet (NVJ) and the north Caledonia jet (NCJ) [Sokolov and Rintoul, 2000;Kessler and Gourdeau, 2007;Gourdeau et al, 2008] before reaching the Australian shelf where they contribute to the formation of the northward flowing North Queensland Current (NQC) and the southward flowing East Australian Current (EAC).…”

[1] Surface velocity observations from satellite tracked drifters made between 1987 and 2008 were used to resolve the surface circulation of the western Coral Sea, west of 158°E, and the Great Barrier Reef (GBR). The mean surface current map depicts well the major circulation patterns of the region, such as the position of the north Vanuatu and north Caledonia jets (NVJ and NCJ) and the western boundary currents. The North Queensland Current (NQC) and the East Australian Current (EAC) are well defined, flowing at speeds greater than 50 cm s −1 to the north, south of 15°S and 19°S, respectively. The NQC/EAC is mainly formed by the NVJ/NCJ flows, respectively. The presence of the Queensland Plateau greatly affects the westward flow, causing a zone of weak and highly variable currents that extends from 15°S to 18°S between the Queensland Plateau and the GBR shelf. Of the 235 drifters that crossed the western Coral Sea, 75 entered the GBR. Analysis of the drifter trajectories inside the GBR reveals the presence of a northwestward circulation at speeds of 22 cm s −1 north of 18°S and 0.5 cm s −1 south of 18°S. Drifter travel times used to evaluate the water residence times within the GBR indicate residence times of a few weeks for most of the lagoon.

“…1); 1 was the prevalent flow direction and 0 was an unlikely flow direction. This visualisation was created with data from modelled and monitored flood plume studies in the GBR (King et al 2001;Devlin and Brodie 2005); the north-western movement caused by the Coriolis effect (Rohde et al 2006); prevailing south-easterly winds in the summer months (Devlin et al 2001); the northward-flowing Hiri current (Brinkman et al 2002) and the southward-flowing East Australian Current (Brinkman et al 2002).…”

Abstract. Rivers flowing into the Great Barrier Reef carry contaminants such as suspended sediments, dissolved inorganic nitrogen, total phosphorus and pesticides. To measure the extent and direction of the contaminants after they enter the Great Barrier Reef lagoon, a model was created using river volume, flooding variability, contaminant load, distance and direction as inputs. A GIS was used to calculate and visualise the exposure of the contaminants to the reefs for the current day, as well as modelling scenarios for pre-European arrival loads, and land management using realistic targets set by a regional Natural Resource Management board for water quality improvement planning purposes. The results show that a reduction in the dissolved inorganic nitrogen load exiting the Tully and Murray Rivers reduces the exposure of reefs close to the basin, but that reefs further east of the basin are significantly influenced by other rivers, highlighting that management for water quality improvement in neighbouring basins is also required.

“…As a result of strong southeast trades during most of the year, the GBR shelf is likely to be well mixed (Church & Craig, 1998). The South Equatorial Current also plays crucial role and different amplitude in water transport which defined by reef density (Brinkman et al, 2001). Those conditions, create high variety of trophic status and productivity which reflected by zooplankton communities (McKinnon et al, 2005).…”

Spatial and temporal variations in the fish and decapod communities were investigated at three stations in Cleveland Bay along with other zooplankton and phytoplankton communities. The linkage between biological assemblages and physical properties of the ocean was explained to develop better understanding of population dynamic of planktonic communities. Biological and physical properties data were gathered in 3 stations by 6 different trips. The results show that there is a significant association between daytime and tidal period to the abundance of planktonic communities (P < 0.05). Spatial distribution of fish and decapod communities are likely explained by "predator pit" and "match/mismatch" concepts to increase the survival probability along with physical properties of the ocean.
