Recent datasets

This dataset contains estimates of diffuse attenuation coefficient (Kd) of downwelling irradiance at different wavelengths (412, 443, 469, 488, 531, 547, 555, 645, 667 and 678 nm) in the Great Barrier Reef Marine Park and Coral Sea for each day from July 2002 through to December 2019. Data are provided on a nominal 1km grid for each wavelength.

This dataset documents the spatial and temporal variability of resuspension events and sediment dynamics at seven Great Barrier Reef Lagoon inshore locations using continuous logger data (10 min sampling intervals) over 3 ½ years and analysed the quantity of sediment collected in newly designed sediment traps. The dataset highlights the influence of river discharge events on sediment dynamics across these locations.

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.

Data is from a series of instruments, including temperature loggers, weather stations and turbidity / salinity loggers deployed at four sites in the Torres Strait (Thursday Island – logger + weather station), Masig Island (logger + weather station), Bramble Cay (Maizab Kaur – logger + weather station) and the northern Warrior Reefs (turbidity and salinity) as part of a larger project to investigate the impact of Fly River discharge waters on the Torres Strait.

The gbr100 dataset is a high-resolution bathymetry and Digital Elevation Model (DEM) covering the Great Barrier Reef, Coral Sea and neighbouring Queensland coastline. This DEM has a grid pixel size of 0.001-arc degrees (~100m) with a horizontal datum of WGS84 and a vertical datum of Mean Sea Level (MSL).

This dataset was developed as part of the 3DGBR project.

The second stream within the NESP 5.5 project was conducted using eye-tracking technology to examine possible differences between three participant groups in evaluating the aesthetic beauty of GBR underwater sceneries. This research continue the efforts initiated in the previous NESP 3.2.3 project to explore the power of eye-tracking as an objective measure of human aesthetic assessment of GBR underwater sceneries.

Organizing focus groups was used as an effective qualitative research method to examine collective opinions of participants on a specific topic. Within NESP 5.5 project, focus groups consist of an exploratory study to explore the psychological antecedents of human aesthetic assessment of underwater sceneries at the GBR among three groups of different cultural backgrounds: Chinese, non-indigenous Australians and First People Australians. Focus group folder contains one dataset report, and three folders (Australian, Chinese, First People) with seven images.

Methods:

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 contains maps of alluvial and hillslope gullies across four large blocks of lidar covering portions of the Burdekin, Fitzroy, and Normanby Catchments. The gully polygons were generated using methods developed in the NESP 5.10 project for the extraction of gullies from lidar. Lidar is detailed topographic data collected from aircraft using an airborne laser scanning system.
