SS2012_T07    - is a Marine National Facility voyage

Period: 2012-10-15 08:30 to 2012-10-23 23:00 UTC

Duration: 8.60 days

From: Darwin To: Cairns

Region: North Eastern Australian Coast, Gulf of Carpentaria and Great Barrier Reef.

Ship: Southern Surveyor [details]

Description: MNF Southern Surveyor research voyage SS2012_t07. 1) Epibenthic communities of northern Australia (Belinda Alvarez de Glasby(MAGNT)). 2) An examination of the microbial oceanography of north-eastern Australia (Martina Doblin (UTS). Scientific Objectives (1) 1. To use a remotely operated underwater video camera (ROV) to explore two areas along the transit voyage track of RV Southern Surveyor from Darwin to Cairns for discovery of habitat-forming and bioactive epibenthic fauna. 2. To collect epibenthic fauna using a sled thereby ground-truthing the video data. 3. To sort, photograph, document and prepare taxonomic vouchers of the samples captured with the benthic sled. 4. To deposit taxonomic vouchers of all samples at MAGNT for curation, registration and distribution to the appropriate taxonomic experts for taxonomic identification. 5. To prepare and freeze suitable samples for screening of bioactive compounds and accession them at the AIMS Bioresources library for future export to the US National Cancer Institute (NCI) laboratories or for research on marine natural products. 6. To correlate biodiversity measure obtained from the survey with available physical datasets from GA (e.g. geomorphology, sediment grain-size). Scientific Objectives (2) The major biotic players in controlling the function of the global ocean are microorganisms. To fully understand the basic biological and chemical dynamics of ocean ecosystems, the identity and role of the microbial assemblages inhabiting seawater must be accurately defined. The proposed research will provide an important new platform for understanding the ecology and biogeochemistry of this region. The specific objectives of the proposed research are to: 1. Provide a first characterisation of the taxonomy, diversity and biogeography of prokaryotic and eukaryotic microorganisms inhabiting Australia's NE ocean waters; 2. Assess the physiological and biogeochemical potential of the microbial communities inhabiting this region; 3. Characterise the light climate to define optical niches for growth of marine primary producers and undertake manipulative experiments to examine optical regulation of carbon fixation; 4. Characterise the eco-physiology and fine-scale community structure of abundant microbial primary producers, including Prochlorococcus, Synechococcus and photosynthetic pico-eukaryotes; 5. Establish and test new microbial oceanography experimentation protocols, while also providing valuable training to students and early career researchers in oceanographic research practices.
