Ice Core Records of Environmental Change

Session ID#: 158571

Session Description:
Ice cores record environmental variability over seasonal to orbital timescales, often at a resolution unmatched by other archives. This session seeks to integrate ice-core records from around the world with data from other paleoclimate archives and/or simulations from climate models to gain insight into past and future environmental change.

We invite contributions on subjects including new ice core projects, results from ongoing or past ice core campaigns, paleoenvironmental reconstructions, new analytical techniques, advances in proxy development and interpretation, integration of ice core records with data from other natural archives or climate model simulations, or glaciological studies that contribute to interpretation of ice core records.

Co-Organized:
  • PP - Paleoceanography and Paleoclimatology
Index Terms:

0365 Troposphere: composition and chemistry [ATMOSPHERIC COMPOSITION AND STRUCTURE]
0724 Ice cores [CRYOSPHERE]
