    IN2018_T02

    [details]    		 Gustaaf Hallegraeff (UTAS/IMAS) Harmful Algal Blooms And Their Long-Term Sediment Record In East Coast Tasmanian Waters (Chief Scientist: Gustaaf Hallegraeff, IMAS/UTAS) Unprecedented toxic dinoflagellate blooms occurred off east coast Tasmania in 2012 and 2015/2016. These events led to a global shellfish product recall (AUD23M loss), lengthy (4 months) closures of mussel, oyster, scallop, and rock lobster fisheries, and 4 human hospitalisations (Paralytic Shellfish Poisoning). While the causative Alexandrium dinoflagellate had been previously detected, genetic evidence suggests that blooms represent a cryptic genotype newly stimulated by climate-driven increased water column stratification. We seek to characterize blooms from with the long time (1000+ yr) ancient DNA sediment record using novel genetic methods.
    IN2018_T01

    [details]    		 Zanna Chase (UTAS) RV Investigator research voyage in2018_t01, titled “Physical, chemical and biogeochemical gradients in the East Australian Current" (Chief Scientist: Dr Zanna Chase, UTAS). This voyage will train Masters students from the University of Tasmania in oceanographic methods. Students will map changes in temperature, salinity and nutrients along 2,500 km of the eastern Australian coast. Biological sampling will document the changes in ocean plankton from the subantarctic waters near Tasmania to the tropics. By observing the change in current biological communities along a south-to-north temperature gradient, students will gain an appreciation of changes that may occur over time due to climate change. Students will gain valuable training in oceanographic field techniques, data analysis and communication.

    IN2016_T02

    [details]    		 A. Bowie (ACE CRC UTAS) Voyage objectives The main objective of this transit voyage is to move the vessel from Hobart to Sydney prior to IN2016_V04. The objectives listed below are complementary with the transit. 1. Natural iron fertilisation of the oceans around Australia: linking terrestrial dust and bushfires to marine biogeochemistry Oceans play a vital role in Earth's climate through the control of atmospheric CO2. An important component of this system is the iron cycle, in which iron-rich aerosols are transported from land via atmosphere to ocean. Iron is a key micronutrient for marine phytoplankton, the scarcity of which controls essential biogeochemical processes. This project will facilitate an integrated ship-based atmospheric observational program for trace elements in oceans around Australia. During the voyages, we will sample and conduct experiments on atmospheric particles containing terrestrial dust, bushfire smoke and anthropogenic emissions that are transported from Australia to its surrounding oceans. This will provide the critical information on atmospheric iron supply for ocean fertility and health, providing the science for predicting a key factor in the future impact of the oceans on climate. The project supports the training and research of two postgraduate PhD students from IMAS-UTAS. 2. We will also opportunistically collect event-based clean rainwater samples using either a polyethylene funnel and collection bottle (when conditions allow) or a Dual Chimney Precipitation Sampler (N-Con Systems model 00-127; currently on order), to quantify the trace metal deposition in the 'bulk' and 'precipitate-only' fractions. Ideally samples would be collected on upper and forward decks, either above the bridge or at the bow when heading into the wind.
    IN2016_T01

    [details]    		 Simon Williams RV Investigator research voyage in2016_t01. Titled "Continuity of Australian terranes into Zealandia: towards a geological map of the east Gondwana margin." This is an extract from the Voyage Objectives in the Voyage Plan. We plan 4-6 dredges on the Fairway Ridge and Sandy Island area. The specific locations of potential dredge sites are shown on the voyage plan image and are tied to a confidential seismic reflection profile and/or swath bathymetry data. As we have access to high-resolution swath data from the area from the Geological Survey of New Caledonia, there is no necessity to plan a detailed swath survey for each dredge site. Swath bathymetry and ocean-bottom profiles (continuous collection) We will continuously collect bathymetric data and the North Loyalty Basin will be crossed during the transit voyage, thus requiring no additional time to collect this important swath profile. Gravity (continuous collection) We will continuously collect gravity data. There is no deviation necessary to obtain gravity measurements over the northwestern part of the Fairway Ridge as we will be crossing this area as part of the dredging component of the survey. CTD, hydrocast and bio-optical cast We will take two daily CTD profiles and hydrocast water samples to 500m to characterise the water at time of deployment for pigment, nutrient, dissolved oxygen, dissolved inorganic carbon and total alkalinity concentrations (up to 25 stations over the whole voyage). For this we will require the 36-bottle CTD rosette. Additional sensors to be included on the CTD frame include chlorophyll and CDOM fluorometers, absorption and backscattering meter, beam transmissometer, dissolved oxygen, deep SUNA and SeaFET pH. A Satlantic radiometer will be deployed separately at each station to a depth of 200m. We will be able to provide sensors that are not available through the MNF equipment pool (i.e. Satlantic SeaFET pH, Satlantic radiometer, Wetlabs acs and bb9, Hobilabs Hydroscat-6). Water samples will be filtered or chemically fixed on board according to standard operating procedures. We anticipate each deployment station taking 1.5 hours, with deployments taking place at the same time each morning and afternoon (nominally 0930 and 1400 hours), when not conflicting with dredge operations. Robotic Profiling Floats and bio-optics CSIRO will provide floats equipped with CTD and bio-optical sensors to measure a range of parameters: T, S, dissolved oxygen, chl and CDOM fluorescence, backscattering (4 wavelengths), beam attenuation, upwelling radiance and downwelling irradiance (4 wavelengths). Floats will be deployed at stations within Australian waters along the ship's route of transit (estimate 155E and 160E). Deployment of the floats can be undertaken from the A-frame off the rear deck or by two people using a rope and manhandling the float over the stern. Once deployed, the floats will descend to depth and start their pre-programmed cycle of profiling and data collection, with data transmitted via Iridium satellites. During each deployment we will also take a CTD profile and water samples to 1000m to characterise the water at time of deployment for pigment, nutrient, dissolved oxygen, dissolved inorganic carbon and total alkalinity concentrations. Additional sensors to be included on the CTD include chlorophyll and CDOM fluorometers, backscattering meter and/or beam transmissometer, dissolved oxygen, deep SUNA and possibly SeaFET pH. We will seek to provide sensors that are not available through the MNF equipment pool (e.g. pH). Water samples will be filtered or chemically fixed on board according to standard operating procedures. We anticipate each deployment station taking 2-4 hours. Additional CTD and bio-optical casts will be taken twice per day (morning and afternoon, nominally 9.30am and 2pm) for bio-optical and biogeochemical sampling around the time of satellite overpasses. Full details available in the Voyage Plan.
