Symposium international sur les glaces, la mer et les changements environnementaux!

The International Glaciological Society tiendra un symposium international en Australie à Hobart du 10 au 14 mars 2014 sur les glaces, la mer et les changements environnementaux.

IGS2014_SeaIce2_logo_0.25

Several topics will be part of the Symposium calendar: 

1) Pole to pole: Large-scale change and variability in sea ice and climate, including: regional to hemispheric response, teleconnections, attribution of change (including large-scale atmospheric and oceanic circulation changes and feedback mechanisms), and possible extreme events. 

  • 2) Seymour Laxon & Katharine Giles celebration session: Advances in sea-ice analysis using remotely-sensed data, including: hemispheric & global assessment, sea-ice thickness and volume, algorithm development & validation, accuracy of retrieved parameters, multi-sensor synergies, new technologies. 

 

  • 3) Advances in instrumentation and observation methods, including: non-destructive observations, autonomous observatories (including underwater & aerial platforms), new analytical methods.

 

 

  • 4) The challenge of melding sea-ice modelling with observations, including: sea-ice and coupled model validation, advances in numerical parameterisations, current gaps, translating observations into models, IPCC-AR5 ensemble synthesis.

 

 

  • 5) A new regime for sea-ice growth and decay?, including: New observations of sea-ice growth & decay processes and of the characteristics of the sea-ice matrix, including the contribution of snow to sea-ice formation & decay (e.g., snow–ice & melt-pond formation), micro-physical properties.

 

 

  • 6) Snow on sea ice, including: snow thickness, density, characteristics and processes, gas exchange, surface radiation budget, and remote sensing considerations.

 

 

  • 7) Interactions between sea-ice drift & deformation and sea-ice morphology, including: ice kinematics, dynamics & mechanics, linkage to floe-size distribution and ice concentration, and dynamical effects on the sea-ice matrix.

 

 

  • 8) Ocean-ice-atmosphere interactions, including: boundary-layer processes, waves, tides, drag coefficients, synoptic scale forcing.

 

 

  • 9) The marginal ice zone, including: processes at the outer ice-ocean boundary, numerical and experimental advances in wave-ice interaction, wave attenuation, and floe-size modification.

 

 

  • 10) Sea ice interaction with ice sheets, ice shelves and icebergs, including: fast ice, polynyas, basal melt and refreeze, water-mass modification, freshwater balance, oceanic heat content, and possible linkage to ice-shelf stability.

 

 

  • 11) The role of sea ice in ecosystems dynamics, including: sea-ice biota, primary productivity, microorganisms, microbial food webs, trophic levels.

 

 

  • 12) Sea-ice biogeochemical properties and processes in a world of change, including: gas fluxes, nutrients, trace elements, carbon & oxygen cycling, brine composition and nutrients.

 

13) Palaeo and pre-satellite sea ice distribution, including: historical records and observations, reconstructions from ice core records and deep-sea sediments… Further info >>
