Jody Webster (U. Sydney) | Project HALO will conduct detailed survey operations at three sites with Halimeda bioherms on the northern GBR shelf and the directly adjacent, deeper offshore areas. The shelf work aims to conduct dense grids of geophysical lines at the three bioherm sites, representing the variety of morphological sub-types, and spread between the Ribbon Reefs and Tijou Reef study areas. We plan to spend ~6 days at each shelf grid site, roughly divided into 1-2 days each for geophysical mapping, sea floor imaging, sea water and seabed sampling. The transits between the shelf sites, are also important to investigate additional Halimeda bioherm areas, paleo-channels, inter-reef passages and the connections to the upper-slope and canyons wherever possible. The deep offshore work will be conducted towards the end of the voyage at three possible slope/basin sites offshore Princes Charlotte Bay and the Ribbon Reefs in transit to Cairns via Grafton Passage. |
