E. Isla Climate Change in Antarctica: a Pelagic-benthic coupling approach to the extremes of the Weddell Sea (CLIMANT) Part of IPY-ICED Funded?
C. Garcia Southern Ocean Studies for Understanding Global Climate Issues (SOS-CLIMATE) Part of IPY-ICED Funded?
J-L.Tison A year-round study of biogeochemistry of Antarctic Sea Ice and the Climate System (BASICS) This research project aims to assess to which extent ice-covered polar oceans contribute to processes regulating the Earth’s climate. The main goal of the project is to study, understand and quantify the physical and biogeochemical processes associated with the sea ice biota that govern the emissions of marine gases of climatic significance.

S. Ackley Sea Ice Mass Balance in the Antarctic (SIMBA) SIMBA will involve deploying ice drifters and mass balance buoys that will continue to operate for 1-2 years after deployment and also an array of under ice ARGO floats plus making insitu and satellite measurements of sea ice, ocean atmosphere and biology. Start Sept.-Oct 2007
K. Heywood, S. Thorpe ADELIE (Antarctic Drifter Experiment: Links to Isobaths and Ecosystems) ADELIE is the Antarctic Drifter Experiment: Links to Isobaths and Ecosystems. The purpose of the project is to map, for the first time, the near surface currents around the Antarctic Peninsula and to determine the role of these currents in the retention and/or dispersal of krill Cruise taking place Feb 2007 Contact K. Heywood
H. Ducklow (general) and K. Baker (data) The Palmer Long-Term Ecological Research (LTER) study Investigations at LTER Palmer site include: 1)physical forcing (solar radiation, atmospheric, oceanic and sea ice) with emphasis on ecological consequences of annual and inter-annual variation; 2) Life-history parameters of secondary producers (krill) and apex predators (penguins); 3) Biological process with emphasis on community structure and carbon fluxes (microbial, phytoplankton); 4)Physical/chemical/biological modeling that links ecosystem processes to environmental variables. Ongoing See Data Page at LTER

Polarstern cruise ANT 23/6: 15 June to 21 August 2006, Polarstern cruise ANT 24/2: December 2007 to January 2008 Data will be stored at Pangea data centre, AWI
G. Mitchell "Blue Water Zone" study Natural iron fertilization study Cruise in Feb 2004 and a further cruise will take place in August 2006
V. Rupolo, G. Budillon, D. Iudicone CANOPO CANOPO will attempt to address the issue of quantifying the CO2 air-sea fluxes in the western part South Atlantic. Surface physical and biogeochemical parameters such as CO2 partial pressure and simultaneous temperature vertical profiles in a transect intersecting the main temperature fronts will be monitored. OGSMs will also be used. First cruise Jan 2005, next cruise austral summer 2007
W. Smith IVARS (Interannual Variations in the Ross Sea)

Investigation into interannual differences in biological processes using historical data, shipboard measurements (inc. Nitrates, phosphates and silica) and 2 moorings.

J. Watkins, E. Murphy CEMI (Circumpolar Ecosystem, Modelling and Integration) Project A large-scale DISCOVERY 2010 (CEMI, FLEXICON & FOODWEBS projects) cruise (austral summer 2007/08) to the region east of South Georgia will provide important large scale information on the fate and population dynamics of Scotia Sea zooplankton. Key studies on this cruise will include large-scale analyses of ocean circulation and krill transport and will utilise ARGO floats capable of mimicking krill vertical migration which will provide essential validation of the Lagrangian particle tracking. As part of an international collaborative research effort we will also collect samples for genetic population structure analysis of krill. Funded
