[details]		 Dr Shadwick (ACE CRC) The Southern Ocean has a predominant role in the movement of heat and carbon dioxide into the ocean interior moderating Earth’s average surface climate. The IMOS SOTS sub-facility uses a set of two automated moorings to measure these processes under extreme conditions, where they are most intense and have been least studied. The atmosphere-ocean exchanges occur on many timescales, from daily insolation cycles to ocean basin decadal oscillations and thus high frequency observations sustained over many years are required. The current context of anthropogenic forcing of rapid climate change adds urgency to the work. The primary objective is to first deploy a new set of SOTS moorings (SOFS-9 and SAZ-22) and then recover the existing SOTS moorings (SOFS-8 and SAZ-21). Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges: • the SAZ sediment trap mooring collects samples to quantify the transfer of carbon and other nutrients to the ocean interior by sinking particles and investigate their ecological controls. • the Southern Ocean Flux Station (SOFS) mooring measures meteorological and ocean properties important to air-sea exchanges, ocean stratification, waves, currents and biological productivity and ecosystem structure. Water samples are collected for more detailed nutrient and plankton investigations after recovery. Ancillary work will obtain supporting information on atmospheric and oceanographic conditions using CTD casts, underway measurements, Triaxus towed body, Continuous Plankton Recorder and autonomous profiling Biogeochemical-Argo floats, and potentially casts of a bio-optical sensor package.
IN2021_V01

[details]		 Dr Kawaguchi (AAD) The primary objective of this voyage is to ensure the orderly development of the krill fishery in waters off Australia’s Antarctic Territory. This will be achieved by updating the biomass estimate of Antarctic krill, enabling a revision of the catch limit within CCAMLR Division 58.4.2-East in the Indian Ocean (IO) sector of the Southern Ocean. Commercial krill fishing in the IO sector recommenced in 2016/17 after a 25 year hiatus. The current krill catch limit in the region is based on surveys conducted 14 years ago. There has been no regular ecosystem monitoring to assess how the system may have changed since then.
IN2020_V09

[details]		 Dr Shadwick (ACE/CRC)

This is the first research voyage since the MNF research schedule was suspended in March 2020 due to the COVID-19 pandemic. Consequently, this voyage will combine into a single voyage two research projects originally scheduled for separate voyages:

  • Southern Ocean Time Series (SOTS) maintenance (Dr Elizabeth Shadwick, CSIRO): Deploy two new SOTS moorings (SOFS-9 and SAZ-22) and recover two existing ones (SOFS-8 and SAZ-21). These automated deep-water moorings measure the exchanges of heat, water, carbon dioxide and oxygen between the ocean and atmosphere, and the physical and biological processes that control them.
  • Oceanographic mooring recovery (Dr Steve Rintoul, CSIRO): Recover an oceanographic mooring deployed during voyage IN2018_V05 to investigate Antarctic Circumpolar Current. This mooring has collected data to improve understanding of how Southern Ocean currents respond to changes in wind speed.
IN2019_V03

[details]		 Lynnath Beckley (Murdoch University) RV Investigator research voyage in2019_v03, titled “A coupled bio-physical, ecosystem-scale, examination of Australia’s International Indian Ocean Expedition line.” The voyage will take place in the SE Indian Ocean along 110°E between 39°30’S and 11°30’S and, to meet the scientific objectives, a wide range of activities will be conducted. Essentially, on station activities can be classified into CTD deployments with associated water sampling, zooplankton sampling with a range of nets and profiling for optical properties and radiometry (Table 2). Several laboratory and on-deck incubation activities will be conducted and deployment of a Continuous Plankton Recorder, micro-zooplankton profiler, Vertical Microstructure Profiler VMP200, ARGO floats, surface drifters and sonobuoys will also take place. The Triaxus with instrumentation will be towed on the return leg back to Fremantle. CTD sampling and the vertical hauls with an Indian Ocean Standard Net (IOSN) are the priority tasks at all stations. After this, in the day time, the optical properties work will be a priority and, at night, plankton sampling with the various nets is the priority. When we were preparing this voyage plan it became apparent that the in-water optics deployments (PI Antoine; objective 4) would take much longer than originally expected. This would result in a considerable reduction of time available to transit between stations so much so that we would not be able to maintain the two stations per day that were done in the original 1960’s 110°E voyages. We subsequently prepared a revised voyage plan and each of the 20 stations on the 110°E line is now occupied for around 16 hours instead of 4 hours. For this voyage, on each station we now plan to complete a morning deep CTD (water for Thompson, Antoine, Ostrowski and Seymour teams) and vertical zooplankton haul with the Indian Ocean Standard Net. This will be followed by the optics measurements in the early afternoon and, in the evening, an EZ net tow, assorted plankton and neuston tows and a shallow CTD to obtain water for experiments and incubations (Raes and Landry). As there will be some time available in the afternoon after the optics measurements, we plan to conduct additional day-time EZ net and plankton tows, vertical microstructure profiling and other sampling that would benefit from day/night comparisons. The final temporal arrangement of these late afternoon activities will be subject to time availability, sea conditions and might change to maximize efficiency. However, the evening surface neuston tows must start promptly at 18:00. This revised plan has no difference from the original voyage proposal with respect to distance travelled by the ship. If we encounter bad weather along the 110°E line, we could wait until it clears using the two-day contingency period. However, if bad weather occurs at the southern-most stations along the 110°E line, the long-term marine weather forecast would have to be considered, as it may be wiser to proceed northwards and skip a station.

[details]		 Thomas W. Trull (CSIRO O&A) Integrated Monitoring Observing System Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania (Chief Scientist: Professor Tom Trull, ACE-CRC) The Southern Ocean Time Series provides world-leading automated observations from deep-ocean moorings of the exchanges of heat, water, carbon dioxide, and oxygen between the ocean and atmosphere, and the physical and biological processes that control them. These results contribute to forward projections of anthropogenic climate warming, inform the setting of emissions targets, illuminate controls on climate variability, and provide a baseline for impacts on ocean pelagic ecology. Sensor data is returned live to the internet and samples are returned annually for further study in shore laboratories. Surface and subsurface subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series site (Lead Principal Investigator: Prof Philip Boyd, UTAS) The Southern Ocean straddles the waters between Australia and Antarctica and has two distinct regions – the subantarctic and the polar seas. The latter is comprehensively studied by expeditions by Australia’s Antarctic Division, whereas the subantarctic has received much less attention. This voyage aims to determine processes within the subantarctic environment that control productivity, foodwebs and cycles of elements such as carbon. Enhanced understanding will maximise investments, such as in ocean time-series in subpolar waters, and enable better predictions to be made on how marine life and chemistry are controlled by both natural and human-made shifts in climate and ocean conditions.
IN2019_V01

[details]		 Michael Double (AAD) RV Investigator research voyage in2019_v01, titled "The availability of Antarctic krill to large predators and their role in biogeochemical recycling in the Southern Ocean." The voyage is also known as "ENRICH (Euphausiids and Nutrient Recycling in Cetacean Hotspots)". We will operate south of 60°S, northward of the ice edge, and between 140°E and 175°W. The specific study area/s within these boundaries will be determined by the locations of vocalising Antarctic blue whales, krill and sea-ice. The survey design is therefore adaptive in that sites will be chosen in real-time on the voyage according to available information. At the commencement of the voyage we will head straight to the closest group of vocalising Antarctic blue whales (ABWs) within our operational area. Vocalising ABWs are able to be detected through sonobuoys (see below) hundreds of kilometres away. When whales are found we will undertake a series of activities at that site. We will then commence a series of line transects in the same region and remain within the same area for the rest of the voyage. The study is therefore on a mesoscale and we do not aim to cover our entire operational area. The activities required to achieve our voyage objectives are: • Passive Acoustics • Whale observing, video-tracking and biopsy • Active Acoustics • Krill trawls • Unmanned Aerial Systems (UASs) • Biogeochemistry
IN2018_V07

[details]		 Eric Schulz (BOM) RV Investigator research voyage in2018_v07, titled “SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania.” Voyage objectives: 1.

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_V03

[details]		 Bernadette Sloyan Integrated Marine Observing System: monitoring of East Australian Current property transports at 27 degrees South (Chief Scientist: Dr Bernadette Sloyan, CSIRO) The East Australian Current (EAC) is the complex and highly energetic western boundary current of the South Pacific Ocean. The EAC is the dominant mechanism for the redistribution of heat and freshwater between the ocean and atmosphere in the Australian region; it is a vital component of the eastern Australian coastal ecosystem. The monitoring of the EAC is central to our understanding of how climate variability is communicated through the global ocean. This ocean current time-series will provide significant insights into the interactions between the EAC, the Pacific basin and the local shelf ocean circulation.

IN2017_T01

[details]		 Andrew Bowie (UTAS) The application will support research to quantify the importance of iron-rich aerosols from Australia for marine biogeochemistry and ocean ecosystem health. The project will sample and conduct experiments on atmospheric particles containing terrestrial dust and bushfire smoke that are transported from Australia to its surrounding oceans. The application supports the training and research of two postgraduate students from IMAS-UTAS. The outcomes will provide a scientific basis for managing the complex role of iron in sustaining marine ecosystem biodiversity and for informing government policy on ocean fertilisation as a carbon mitigation strategy.
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.

IN2015_V01

[details]		 T. Trull (CSIRO O&A); E. Schulz (BOM) MNF RV Investigator Research Voyage IN2015_v01. IMOS Southern Ocean Time Series(SOTS) Automated Moorings for Climate and Carbon Cycle Studies Southwest Of Tasmania. Scientific objectives: The Southern Ocean has a predominant role in the movement of heat and carbon dioxide into the ocean interior moderating Earth's average surface climate. SOTS uses a set of three automated mooring to measure these processes under extreme conditions, where they are most intense and have been least studied. The atmosphere-ocean exchanges occur on many timescales, from daily insolation cycles to ocean basin decadal oscillations and thus high frequency observations sustained over many years are required. The current context of anthropogenic forcing of rapid climate change adds urgency to the work. Voyage objectives: The primary objective is to deploy a full set of SOTS moorings (SOFS, Pulse, and SAZ) and to obtain ancillary information of the oceanographic conditions at the time of deployment using CTD casts, underway measurements, the Triaxus towed body, and deployment of autonomous profiling Bio-Argo floats. Each of the SOTS moorings delivers to specific aspects of the atmosphere-ocean exchanges, with some redundancy: i) the Southern Ocean Flux Station (SOFS) focuses on air properties, ocean stratification, waves, and currents. ii) the Pulse biogeochemistry mooring focuses on processes important to biological CO2 consumption, including net community production from oxygen measurements and nitrate depletion, biomass concentrations from bio-optics and bio-acoustics, and collection of water samples for nutrient and plankton quantification. iii) the SAZ sediment trap mooring focuses on quantifying the transfer of carbon and other nutrients to the ocean interior by sinking particles, and collecting samples to investigate their ecological controls. Additional water sampling and sensor comparisons against shipboard systems provide quality control and spatial context, which is further augmented by Bio-Argo float and Triaxus towed body deployments, and satellite remote sensing.
