| Results and Impact | The aim of this workshop is to bring together interdisciplinary Antarctic research expertise to discuss the fate of nutrients that have accumulated in Antarctic snow and glacier ice. We also wish to discuss the in-situ and "downstream" processes that govern the export and potential impact of nutrients to ice marginal ecosystems such as the oceans. Emphasis will be given to the relevant processes during the first day of the workshop, leading to a presentation of the key tools for quantifying cryospheric change, biogeochemical fluxes and Antarctic ecosystem response in the second. Thereafter, we will identify crucial research needs and strategies for the next ten years. 09:00-10.00: Registration and coffee 10:00-10:30: About the workshop including the timetable, layout and scope 11.00-13:00: Session 1: Microbiology 11.00-11.30 Marie Sabacka - Microbial processes in glacier snowpacks in maritime Antarctica 11.30-12:00 Iordanis Magiopoulos - Bacterial diversity and detection in Antarctic snow and ice 12.00-12.30 Chris Bellas - Virus induced mortality in cryoconite and it's implications for glacial run off 12.30-13.00 David Pearce - Microbial biogeography and what it means to ecosystem function 13:00-14:00: Lunch 14:00-15:30: Session 2: Fluxes 14.00-14.30 Andrew Hodson - Glacial run-off and marine fertilization 14.30-15.00 Amy Jowett - An optimised temperature parameterisation for use in Greenland ice sheet mass balance modelling: 1870-2013 15.00-15.30 Andrew Sole - Effects of ice sheet runoff on submarine melt rates and circulation in Greenlandic fjords 15:30-16:00: Coffee break 16:00-17:30: Discussion: i) horizon scan (16.00) and ii) tackling the big questions (16.45) 19:00-: Dinner & socializing (Pub on Northumberland Road by the Wok Inn then Las Iguanas) Day 2: Ellison Building A002 / Rutherford Hall 09:00-10:30 Session 3: Tools and technology 09.00-09.30 Andrew Hodson - Towards a regional study - the melting cryosphere 09.30-10.00 Chris Cardwell - NOC - Engineering for Oceanography 10.00-10.30 Pete Convey - Polar Fieldwork Opportunities - working with the British Antarctic Survey 10:30-11:00 Coffee break 11:00-13:00 Session 4: Ecological processes 11.00-11.30 Stuart Dunning - Landslides, hillslope processes and relief evolution 11.30-12.00 Nick Rutter - Modelling temporal and spatial variation of snowpack 12.00-12.30 Benjamin Brock - Direct measurement of surface carbon fluxes using an eddy covariance system: inferences on microbial activity in supraglacial rock debris 12.30-13.00 Justin Perry (Postdoc) - Developing technologies 13:00-14:00: Lunch 14:00 - 15:00: Session 5: 14.00-14.30 Ros De'Ath - The Antarctic ice sheet and fertilization of the Southern Ocean 14.30-15.00 Edward Hanna - Modelling snow melt runoff 15:00-16:00: Discussion groups 16:00-16.30: Synthesis: Research needs and opportunities 16:30-17:00: Closing Remarks |
