| Title: | Multibeam bathymetry mapping of the Great Barrier Reef and Coral Sea |
| Id: | 2520 |
| Investigator(s): | Robin Beaman
James Cook University - School of Earth and Environmental Sciences [details] |
| Description: | The scientific and voyage objectives of Project 3DGBR are: 1.To acquire high-resolution multibeam bathymetry, backscatter and water column data along the voyage track for the duration of the voyage. The new bathymetry data will be used to improve the accuracy of the 100 m-resolution DEM for the Great Barrier Reef and Coral Sea, called the ‘gbr100’ grid: http://www.deepreef.org/bathymetry/65-3dgbr-bathy.html 2.On an opportunity basis and subject to workload, acquire sub-bottom profile data using the SBP120 profiler during the voyage. The sub-bottom profiler data will be used in conjunction with the multibeam data for ongoing marine geoscience projects in the Great Barrier Reef and Coral Sea.

| IN2022_T01 [details] |
MNF | The primary objective of voyage IN2022_T01 is movement of RV Investigator from Cairns to Darwin in preparation for IN2022_V08. Underway training, repairs, maintenance and science operations will occur whilst en route without impacting the voyage departure and arrival times. Piggyback Projects: Project 3D-GBR & underway scientific mapping. Sea Surface Temperature Radiometer Comparisons/Calibrations. 1x ARGO BioGeoChemical (BGC) float deployment. |

Professor Zoran Ristovski (QUT) | RV Investigator research voyage in2016_v05, titled "The Great Barrier Reef as a significant source of climatically relevant aerosol particles." Voyage objectives The main objective of the voyage is to acquire observations that will address four key science questions about the role of atmospheric composition in the GBR region: 1. Do marine aerosols along the north Queensland coast have a significant signature that is coral derived? 2. How does this aerosol change its physicochemical properties, especially its capacity to act as CCN, as winds carry it from the reefs to the north Queensland rainforests? 3. What is the significance of this ecosystem as a source of aerosol particles and will potential degradation of the reef cause significant variations in particle number being generated over the reef. 4. Should changes in this aerosol, associated with reef degradation, be taken into account when modelling the radiative climate and rainfall? * Two stations on the western side of the GBR. These stations will enable us to sample the air masses that have traversed over the reefs and have been enriched by the emissions from the reefs. * One station on the eastern side of the GBR. As the predominant wind direction during the trade wind season is south easterlies this station will enable us to characterise the remote pacific air masses coming towards the GBR. * Optics station in deep water (>200m) east of Heron Island to characterise the sea surface spectral reflectance and in water optical properties including the spectral absorption of optically active constituents in the water. Supplementary Project: Biogeochemical and optical properties of the Coral Sea and Queensland Shelf Objectives 1. To collect high resolution biogeochemical observations for validation of the 4km and 1km near real time eReefs models (https://research.csiro.au/ereefs/) 2. To get modellers in the field to better understand methods and issues associated with modern methods of data collection 3. To collect in situ optical data for the NASA CORAL project which is operating a very high resolution airborne hyperspectral sensor along selected transects in the GBR.
