This dataset shows larval connectivities between reefs that exceeded, and did not exceed, thermal thresholds for damage during the 2016/2017 Great Barrier Reef bleaching events. The loss of reproductive adult colonies during bleaching events has the implication that coral cover recovery will require the supply of coral larvae from external sources (other reefs).

This dataset contains RTK GPS Data collected between April, 2017 and March, 2018 for 5 paired Control/Treatment gully sites being monitored as part of NESP Project 2.1.4 (Demonstration and evaluation of gully remediation on downstream water quality and agricultural production in GBR rangelands). The key question being asked is “is there measurable improvement in the erosion and water quality leaving remediated gully sites compared to sites left untreated?” The monitoring approach uses a modified BACI (Before after control impact) design.

Conservation and repair of the coastal wetland ecosystems’ in the Great Barrier Reef catchments have come into focus following media converging on the point that the reef health and land use in catchments has been compromised. While on-ground wetland repair investment activities are underway, data to demonstrate water quality and biodiversity return for the investment is not available.

Monitoring of these sites is continuing as part of NESP TWQ Project 5.9.

This dataset contains Vegetation and Biomass monitoring data collected for the NESP Project 2.1.4 (Demonstration and evaluation of gully remediation on downstream water quality and agricultural production in GBR rangelands). The aim of the vegetation monitoring in relation to this project is to track change in biomass and species composition over time on hillslope areas above gully erosion within control and treatment sites (treatments vary), linking to changes in downstream water quality.

This dataset contains Riegl terrestrial laser scanner scans and their derived 5 cm gridded digital elevation models (DEMs) collected for up to 4 years between 2016 and 2019 for 4 paired Control/Treatment gully sites being monitored as part of NESP Project 2.1.4. Data collection also contains the DEMs of difference used to estimate changes in gully volume. The data in presented in this metadata are part of a larger collection and are intended to be viewed in the context of the project.

This dataset contains preliminary estimates of discharge and loads (Total suspended sediment and total nitrogen) based on monitoring data collected for the NESP Project 2.1.4 Demonstration and evaluation of gully remediation on downstream water quality and agricultural production in GBR rangelands. The data in presented in this metadata are part of a larger collection and are intended to be viewed in the context of the project.

Five paired Control/Treatment gully sites on commercial grazing properties in the Upper Burdekin and Bowen catchments are being monitored as part of NESP Project 2.1.4 (Demonstration and evaluation of gully remediation on downstream water quality and agricultural production in GBR rangelands) (Bartley et al., 2018). The key question being asked is: "Is there measurable improvement in the erosion and water quality leaving remediated gully sites compared to sites left untreated?" The monitoring approach uses a modified BACI (Before after control impact) design.

This dataset consists of a review of case studies and descriptions of coral restoration methods from four sources: 1) the primary literature (i.e. published peer-reviewed scientific literature), 2) grey literature (e.g. scientific reports and technical summaries from experts in the field), 3) online descriptions (e.g. blogs and online videos describing projects), and 4) an online survey targeting restoration practitioners (doi:10.5061/dryad.p6r3816). Included are only those case studies which actively conducted coral restoration (i.e.

Despite the seemingly abundant opportunities, Indigenous Traditional Owners of the Great Barrier Reef appear to show little interest in participating in the lucrative coral reef tourism industry. This project seeks to understand why this is so, canvass TO attitudes to the industry, map out the opportunities for their participation in both mainstream and Indigenous-initiated ventures, and provide an assessment of current obstacles and what can be done to mitigate them.

This research was conducted to understand the relationship between water quality and ecological attributes on coral reef communities, through field surveys on naturally turbid inshore coral reefs that vary in exposure to water bourne sediment, nutrient and chlorophyll concentrations. Reefs in two regions were surveyed for biodiversity of algae, hard corals, octocorals and fish. Region PC: Princess Charlotte Bay (in the Claremont Isles, north of PC Bay) and and Region WT: Wet Tropics (between Tully and Port Douglas).

This dataset contains the results of the water quality monitoring program conducted across the Russell-Mulgrave catchment (south of Cairns) for "Project 25". Project 25 spanned two (2) NESP TWQ projects: 2.1.7 (2016 - 2018) and 4.8 (2019 - 2020), with the dataset for Project 4.8 also containing the data for Project 2.1.7. Data is the result of discrete ‘grab’ samples analysed at TropWATER JCU laboratory for nutrients and sediments.

This dataset contains benthic photosynthetically active radiation (PAR; bPAR) at the Q-IMOS Myrmidon, Palm Passage and Heron Island South mooring stations from May 2016 through to November 2017. This dataset was collected to provide in situ reference data for calibration/validation of a remote sensing ocean color model to estimate bPAR (benthic photosynthetically active radiation) as part of NESP Tropical Water Quality Hub project 2.3.1.

This dataset shows the results of mapping the connectivity of key values (natural heritage, indigenous heritage, social and historic and economic) of the Great Barrier Reef with its neighbouring regions (Torres Strait, Coral Sea and Great Sandy Strait). The purpose of this mapping process was to identify values that need joint management across multiple regions. It contains a spreadsheet containing the connection information obtained from expert elicitation, all maps derived from this information and all GIS files needed to recreate these maps.

This dataset consists of three data files (spreadsheets) from a two month aquarium experiment manipulating pCO2 and light, and measuring the physiological response (photosynthesis, growth, protein and pigment content) of the adult and juvenile stages of two species of tropical corals (Acropora tenuis and A. hyacinthus). Methods: We conducted a two-month, 24-tank experiment at AIMS’s SeaSim facility, in which recently settled juvenile- and adult-colonies of the corals Acropora tenuis and A.

This dataset summarises the results of a survey to determine the concentration of trace metals from mine-derived pollution in marine waters and sediments across the Torres Strait during October 2016. Sampling was performed by a CSIRO team between 3 and 16 October 2016 on board the MV Eclipse. Surface water samples were collected from 21 sites using strict sampling protocols that are designed to minimise contamination (USEPA, 1996; Angel et al., 2010b).

This dataset summarises the results of a survey of water quality and suspended solid metal data for ten (10) sites around Saibai and Boigu Islands in the Torres Strait during November 2018. This is the second survey for this project, where the first survey identified the area around Saibai as having elevated metal concentrations compared to other areas of the Torres Strait. This survey was conducted to investigate this finding. Water samples were collected from five sites around Saibai Island and five sites around Boigu Island.

The dataset consists of four data files from a 20-day experiment to investigate different photophysiological responses of two species of coral (Acropora millepora and Pachyseris speciosa) to constant and variable daily light integrals. Methods: Eight partial colonies each of Pachyseris speciosa (from 5 – 8 m depth) and Acropora millepora (from 3 – 5 m depth) were collected from Davies Reef, central Great Barrier Reef, Australia (-18.823390, 147.6518563) in July 2016, and taken to the National Sea Simulator at the Australian Institute of Marine Science (AIMS), Townsville.

The dataset consists of tables of means, with statistical differences indicated where they are significant, for measured crop performance, fertilizer N recovery and use efficiency at 6 field sites from Mackay to Freshwater. Runoff losses of N are also shown from sites at Freshwater and Silkwood. **This dataset is currently under embargo until December 2021.
