Abstract: High-alpine glaciers and polar ice sheets are invaluable archives of past environmental conditions and climate. Since direct measurements of the atmospheric composition are basically not available before the 1970s, these natural archives are unique to put recent observations into a longer-term context and assess the anthropogenic impact in relation to natural changes in atmospheric constituents. This presentation will give an overview of how ice cores are collected and analysed. Examples of air pollution records and the challenges to extract them will be discussed.
What is the Joint Oslo Seminar (JOS):
- Atmospheric and climate sciences have a stronghold in Oslo among the four institutions University of Oslo, the Meteorological Institute, CICERO and NILU.
- This joint seminar invites renowned international experts to contribute to an informal series of lectures, meant to create interaction with the Oslo atmospheric and climate science community on recent highlights and analysis in the field.
- Normally seminars will be held on Thursdays (12:15 pm -1pm).
