Towed Video surveys down to a depth of ~50 m was completed successfully at the following shoals (Baracuda East, Goeree Shoal, Vulcan Shoal). Sampling involved habitat classification conducted in real-time during the surveys, and taking photographic still image at 5s intervals for subsequent analysis as the cameras were towed across the shoals at a speed of 1-2 knots. This project is a co-investment between PTTEPAA and AIMS, in order to build scientific knowledge on a number of shoal features in the area near Montara and was undertaken between 19/9/2016 - 24/9/2016.

Towed Video surveys down to a depth of ~50 m was completed successfully all at the following 9 banks and shoals (Baracuda East and West Shoals, Sheldon Shoal, Wave Governor Bank, Heywood Shoal, Echuca Shoal, Goeree Shoal, Eugene McDermott Shoal, Vulcan Shoal). Sampling involved habitat classification conducted in real-time during the surveys, and taking photographic still image at 10 s intervals for subsequent analysis as the cameras were towed across the shoals at a speed of 1-2 knots.

A total of 365 towed video transects were completed in the 2006/2007 surveys. The sampling has identified a vast array of habitats and will be used for broad scale mapping of benthic communities in the marine park, however further transect tows will be conducted in 2008 in areas of special interest, where sampling is considered limited and where ground-truthing is required. Towed video sampling effort was concentrated around Mandu, Osprey, Yardie, Winderabandi and Point Cloates in 2006.

Stereo Baited Remote Underwater Video Stations (BRUVS) were successfully deployed and retrieved at each of the 3 shoals (Baracuda East , Goeree Shoal, Vulcan Shoal). Deployments were restricted to 250 m. In general 24 stereo BRUVS were deployed at each shoal. This project is a co-investment between PTTEPAA and AIMS, in order to build scientific knowledge on a number of shoal features in the area near Montara and was undertaken between 19/9/16 - 24/9/16.

This metadata record describes salinity and temperature time-series data collected through in situ monitoring by the Great Barrier Reef Marine Monitoring Program for Inshore Water Quality (MMP WQ). A full description of the MMP WQ and its associated datasets can be found in the parent metadata record linked above. Continuous in situ salinity and temperature were measured using Sea-Bird Electronics SBE 37-SM conductivity and temperature sensors. The MMP WQ currently has instruments deployed at 9 sites summarised by Natural Resource Management (NRM) region below.

Stereo Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved across two shoals of regional interest, Evans and Tassie Shoals, two of the closest shoals to the Barossa field. The allocation of deployment positions across each shoal was conducted using a regular/random design within the bounds of the 60 m depth contour whilst maintaining a minimum distance of 250 m between each stereo-BRUVS unit. Once the positions were derived, the sequence of deployments, in sets of eight replicate units, was determined by proximity and prevailing sea conditions on the day.

Towed video surveys were carried out across five principle locations of regional interest, including Evans, Tassie and Blackwood Shoals, the closest shoals to the Barossa field, as well as two mid-shelf seabed locations adjacent to Goodrich Bank and Cape Helvetius. In total, 113 towed video transects and 2246 downward facing digital still images were collected at depths of between 11 and 100 metres.

Stereo Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved across targeted shallow seabed environments within and adjacent to the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea. The survey concentrated on shelf habitats (< 200m) of the Oceanic Shoals CMR and included potential biodiversity hotspots such as pinnacles, banks and shoals.

Towed video surveys were carried out in targeted shallow seabed environments within the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea. The survey concentrated on shelf habitats (< 200m) of the western part of the Oceanic Shoals CMR and included potential biodiversity hotspots such as pinnacles, banks and shoals. In total, 52 towed video transects were collected at depths of between 31 and 129 metres.

Stereo-Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved in targeted shallow seabed environments within the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea. The survey concentrated on shelf habitats (< 200m) of the western part of the Oceanic Shoals CMR and included potential biodiversity hotspots such as pinnacles, banks and shoals. In total, 56 stereo-BRUVS were deployed between 31 and 77 metres for one hour according to a regular random sampling design, with minimum spacing of 400 m to ensure independence among samples.

This dataset contains hillshading derived from the Digitial Elevation Model (DEM) dataset: Australian bathymetry and topography grid, June 2009 version 4 by Geoscience Australia. This dataset also contains the original DEM converted to a GeoTiff. The hillshading was produced using the gdaldem tool. The rest of this documentation is based on the metadata of the Australian bathymetry and topography grid itself. This grid is available from GA at http://dx.doi.org/10.4225/25...9B6581B9A .

State and Federal agencies are funding many GBR wetland system repair projects (Mungalla wetlands $1.2M; Reef Trust/Greening Australia $4M; Restoring Burdekin Coastal Ecosystems $837K; Roundhill Creek wetland/FHA $65K, Babinda Swamp Constructed Wetland ~$1.97M). The problem is no scientific data evaluates their success; this project partners with NRMs to fill this R&D gap. Using advanced scientific hydrological and ecological techniques we will generate data to evaluate repair efforts, providing surety to government funding agencies.

Report cards are used at various levels to summarise and communicate complex information on GBR health. The effectiveness of Reef Plan is communicated through the annual Reef Report card. In the Reef Report Card, marine water quality is reported using a metric, developed in 2009, based on satellite remote sensing of near surface concentrations of chlorophyll and total suspended solids. This provides a wide spatial and temporal coverage of marine water quality.

This project will derive ecologically relevant targets (ERTs) for water quality and sediment loads by: 1) defining seagrass desired state targets; 2) calculating water quality guidelines (light); and 3) calculating ERTs for terrestrially sourced sediment loads. Historical and new data collections will be used to derive ERTs via statistical models and eReefs (RECOM), and the seagrass sub-model in eReefs will be used to test ERTs.

This project addresses the urgent need to understand and monitor the aesthetic value of the Great Barrier Reef. Focusing on the fast-changing underwater systems of the Reef, this research will use advanced technology (including eye tracking and heart rate measurement) to elicit what environmental and experiential attributes contribute to aesthetic value. A Big Data platform using artificial intelligence will be created to assess large volumes of visitor supplied imagery and to map aesthetic value across space and time.

Point of contact

This project extends project 2.1.3 which contains an analysis of communications to land holders for the Reef Trust Tender – Burdekin and The Reef Programme concerning readability, message framing, message tone and visual imagery, factors that significantly impact on message acceptance, engagement and adoption of recommended behaviours. The analysis identified that: 1. Material is written in too complex language; 2. Message tone may be a barrier; and 3. Visual imagery may have unintended effects.
