Hobart provides a natural deep water harbour adjacent to the main city centre
Tasmania as an Antarctic Gateway $24M investment over 3 years to further built Hobart s profile as an Antarctic Gateway (Federal Government) Build research capacity across institutions Provide additional logistics capability Australian Gov t has a 20- year strategy discussion document for our Antarctic program - recently released Investment in Sea Ice Services (2 people) Longer-term aspiration to develop sea ice forecasting capability (24 72 hours + seasonal) Keen to work with other nations and leverage experience of Arctic operators!
Australian Activities in Antarctica - a Typical Year At least one visit to each station Over 10,000 tonnes of cargo delivered Over 500 passenger return trips by ship or air Over 50,000 occupied bed nights Over 6 million litres of fuel used for station electrical plants, shipping, aviation, vehicles, etc. Scientific research at sea, on stations and in the deep field
Shipping and Aviation in 2013/14

Bureau of Meteorology Australia s Bureau of Meteorology has primary responsibility for providing weather forecasts in support of operational, research and SAR activities in Antarctica and the Southern Ocean.

Current ACCESS models
ACCESS P the initial version Polar atmospheric forecast model developed within the Bureau of Meteorology. Replacement of PolarLAPS Nested within ACCESS-G APS1 and run in near-real-time at 00Z and 12Z out for 72 hours. ~27km greater Antarctic region Australian version of the UK Met office UM.
ACCESS P the new version proposed) ACCESS P: 11km atmosphere only (initially) regional model 700x700 grid points, 72 levels Nested within ACCESS G (24km) Covers the greater Antarctic region including sea ice extent Will eventually couple an ocean/sea ice to the atmosphere model Used for: Intercontinental aviation (Hobart to bases) Shipping
Antarctic Gateway: Sea Ice Information Service Growing demand for sea ice information to aid navigation Australian research vessel Aurora Australis and other vessels operating in the Antarctic sea ice zone Research institutions in Hobart have been working to provide relevant information Aspire to further develop the Sea Ice View Tool and transition to more robust operational service, including sea ice forecasting Currently Sea Ice View Tool: Near-Real-Time delivery to any computer on ship or... Rapid delivery of current data / information (individual products - in general not synthesis) Two data types: images = regular grid (raster) in geographic projection points = points, lines, polygons (vector) e.g. Ice edge, ship track Various satellite sensor types and characteristics (data delivered as images ): Visible MODIS (ATSR, MERIS, VIIRS, AVHRR,... Plus Landsat, etc) Infra-red MODIS as single or multi-channel (ATSR, VIIRS, AVHRR) Active Microwave = imaging radar, scatterometer (Passive Microwave as brightness temperature) Products and delivery tailored to ship s communications and user requirements. Future involvement in Antarctic sea ice charting needs a discussion and resources.

Conclusions Growing demand for sea ice products to be delivered to vessels to aid navigation Preference to deliver images and tools for interpretation, rather than ice charts per se Investment by Australian Government to provide initial service (3 years) Looking for opportunities to leverage investment and build capacity and capability with partners Longer-term aspiration to develop sea ice forecasting capability (24 72 hours + seasonal) Keen to work with other nations and leverage experience of Arctic operators!
