| Title: | Dinoflagellates & broader planktonic assemblage observation |

| Investigator(s): | Matt Gordon
Defence Science and Technology Organisation [details] |
| Description: | Dinoflagellates are a ubiquitous and ecologically important component of marine phytoplankton communities, with particularly notable species including those associated with harmful algal blooms (HABs) and those that bioluminesce. High-throughput sequencing offers a novel approach compared to traditional microscopy for determining species assemblages and distributions of dinoflagellates, which are poorly known especially in Australian waters. The major aims for data collection activities during this voyage are: |

| IN2022_V07 [details] |
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. |
| IN2021_T01 [details] |
V. Puigcorbe (Edith Cowan University) | RV Investigator transit voyage between Brisbane and Darwin: in2021_T01, with the following supplementary and piggyback projects: The primary objective of voyage IN2021_T01 is movement of RV Investigator from Brisbane to Darwin in preparation for IN2021_V04. Up to 72 hours of the transit voyage have been allocated to conduct scientific operations which will consist of a minimum of 12hrs devoted to the Supplementary Project: Microplastics in the food chain: impact on the microbial and planktonic organisms. The remaining time can be available for multiple Piggyback Projects. Some opportunistic mapping has been prepared should we be ahead of schedule. |
