ASPECT  

Definition

  • ASPeCt is a programme of multi-disciplinary Antarctic sea ice zone research within the SCAR Global Change Programme. ASPeCt will specifically address key identified deficiencies in our understanding and data from the sea ice zone. The programme is designed to complement and to contribute to the other international programmes in this region and will build on existing and proposed research programmes, and the shipping activities of National Antarctic operators, and will also include a component of data-rescue of valuable historical sea ice zone information. The overall aim of ASPeCt is to understand and model the role of Antarctic sea ice in the coupled atmosphere-ice-ocean system. This requires an understanding of key processes, and the determination of physical, chemical, and biological properties of the sea ice zone. These are addressed by objectives which are: I. To establish the distribution of the basic physical properties of sea ice that are important to air-sea interaction and to biological processes within the Antarctic sea-ice zone (ice and snow cover thickness distributions; structural, chemical and thermal properties of the snow and ice; upper ocean hydrography; floe size and lead distribution). These data are required to derive forcing and validation fields for climate models and to determine factors controlling the biology and ecology of the sea ice-associated biota. II. To understand the key sea-ice zone processes necessary for improved parameterization of these processes in coupled models.
