... The content of the river discharge has changed through time with large increases in the loads of sediments, nutrients, and pesticides associated with the expansion of agricultural development of the GBR catchment [10][11][12]. Persistent, above average river flows over a seven year period have been associated with a number of changes in the GBR communities, such as reduction in seagrass cover [13], impacts on coral cover, increase in coral disease [14], and high mortality rates of dugongs and turtles [15][16][17]. Management agencies in Australia are responding to these issues with the Australian and Queensland (State) Governments committing to the Reef Water Quality Protection Plan [10], a bilateral policy (initiated in 2003), that aims to ensure that 'by 2020 the quality of water entering the GBR from broadscale land use has no detrimental impact on the health and resilience of the GBR'. The plan identifies a range of strategies and actions to achieve this goal including prioritisation of investment, adoption of improved land management practices, and evaluation of performance [18]. ...

A strong driver of water quality change in the Great Barrier Reef (GBR) is the pulsed or intermittent nature of terrestrial inputs into the GBR lagoon, including delivery of increased loads of sediments, nutrients, and toxicants via flood river plumes (hereafter river plumes) during the wet season. Cumulative pressures from extreme weather with a high frequency of large scale flooding in recent years has been linked to the large scale reported decline in the health of inshore seagrass systems and coral reefs in the central areas of the GBR, with concerns for the recovery potential of these impacted ecosystems. Management authorities currently rely on remotely-sensed (RS) and in situ data for water quality monitoring to guide their assessment of water quality conditions in the GBR. The use of remotely-sensed satellite products provides a quantitative and accessible tool for scientists and managers. These products, coupled with in situ data, and more recently modelled data, are valuable for quantifying the influence of river plumes on seagrass and coral reef habitat in the GBR. This article reviews recent remote sensing techniques developed to monitor river plumes and water quality in the GBR. We also discuss emerging research that integrates hydrodynamic models with remote sensing and in situ OPEN ACCESS Remote Sens. 2015, 7 12910 data, enabling us to explore impacts of different catchment management strategies on GBR water quality.

A risk assessment method was developed and applied to the Great Barrier Reef (GBR) to provide robust and scientifically defensible information for policy makers and catchment managers on the key land-based pollutants of greatest risk to the health of the two main GBR ecosystems (coral reefs and seagrass beds). This information was used to inform management prioritisation for Reef Rescue 2 and Reef Plan 3. The risk assessment method needed to take account of the fact that catchment-associated risk will vary with distance from the river mouth, with coastal habitats nearest to river mouths most impacted by poor marine water quality. The main water quality pollutants of concern for the GBR are enhanced levels of suspended sediments, excess nutrients and pesticides added to the GBR lagoon from the adjacent catchments. Until recently, there has been insufficient knowledge about the relative exposure to and effects of these pollutants to guide effective prioritisation of the management of their sources.

The Reef Rescue Marine Monitoring Program (MMP) undertaken in the Great Barrier Reef lagoon assesses the long-term effectiveness of the Australian and Queensland Government’s Reef Water Quality Protection Plan and the Australian Government Reef Rescue initiative. The MMP was established in 2005 to help assess the long-term status and health of Reef ecosystems and is a critical component in the assessment of regional water quality as land management practices are improved across Reef catchments. The program forms an integral part of the Reef Plan Paddock to Reef Integrated Monitoring, Modelling and Reporting Program supported through Reef Plan and Reef Rescue initiatives. This report details the sampling that has taken place under the Reef Rescue Marine Monitoring Program: Terrestrial discharge into the Great Barrier Reef (project 3.7.2b) for the 2011/12 sampling year.

The prevalence and severity of marine diseases have increased over the last 20 years, significantly impacting a variety of foundation and keystone species. One explanation is that changes in the environment caused by human activities have impaired host resistance and/or have increased pathogen virulence. Here, we report evidence from field experiments that nutrient enrichment can significantly increase the severity of two important Caribbean coral epizootics: aspergillosis of the common gorgonian sea fan Gorgonia ventalina and yellow band disease of the reef-building corals Montastraea annularis and M. franksii. Experimentally increasing nutrient concentrations by 2–5· nearly doubled host tissue loss caused by yellow band disease. In a separate experiment, nutrient enrichment significantly increased two measures of sea fan aspergillosis severity. Our results may help explain the conspicuous patchiness of coral disease severity, besides suggesting that minimizing nutrient pollution could be an important management tool for controlling coral epizootics.

Within the last decade infestations of the crown-of-thorns starfish (Acanthaster planci) have been reported from the Great Barrier Reef, Guam and other Mariana Islands, Caroline Islands, Marshall Islands, Palau Islands, New Hebrides, Solomon Islands, Fiji Islands, Western Samoa, Cook Islands, Tahiti in the Society Islands, Molokai in the Hawaiian Islands, Philippine Islands, Taiwan, and Ceylon. The starfish have also been noted as common in Viet Nam, Tanzania, Tonga Islands, Gilbert Islands, Nauru, Papua, New Caledonia, Ko Khao (off Thailand), Wake, the Tuamotu Archipelago, and near Port Sudan, Red Sea. Within these areas the distribution of the starfish is spotty. Nearly all of the infestations are near centers of human population. Some authors believe these infestations are merely normal fluctuations of abundance that have gone unnoticed in the past. The magnitude of some of the starfish plagues, however, seems too great for this explanation. The crown-of-thorns has killed up to 90 percent or more of corals on some reefs that represent more than 1000 years of continuous development. Also the areas of infestation are too numerous, too widespread, and have occurred over too short a span of time to believe that each is the result of an independent natural cycle. It is postulated that chemical pollution, most likely in the form of chlorinated hydrocarbon pesticides such as DDT, is responsible for the increased populations of A. planci. The pollutant's effect probably takes place in the pelagic community. A higher level of the pollutant may be expected in the predaceous zooplankton that feed on the larval starfish than in the larvae themselves. A level of pesticide must exist which reduces the population of one or more predators relative to the number of starfish larvae. The localization of the infestations of A. planci is probably the result of the chance combination of many factors such as a successful spawning of the starfish, the correct temperature for development, and the transport of the larvae in a current system (a gyre is needed to maintain the population at the island or reef of origin) to a suitable inshore environment for settlement. The excessive populations of sea urchins (Strongylocentrotus) in the coastal waters of southern California may also be a comparable effect of chemical pollution.
