It has been ca. 10 years since the last specific meeting for the “varve community” was held at the Lammi Biological station in Finland. Since that, there has been a great amount of new publications on varved sediments, some of them describing methodological developments and others forming a basis of interpretation of climate and environmental change of post-glacial times. In many studies, the varve chronology of lacustrine and marine sediments form a solid basis of dating, not to mention the environmental and climate signal that is stored in varves and laminae they contain.
Now it is time to take a step forward and gather the varve community together once again to summarize what has been accomplished during the last 10 years and to exchange new ideas and promote their use in global climate reconstructions. The Varves Working Group (VWG) has formed under the frame of the PAGES CCT1 “Chronology” to address a number of topics with workshops and products and is also co-sponsored by INQUA as Project Number 1102.
The VWG topics include:
- Methodological developments
- Marine versus lacustrine varves
- Varve chronologies, including quantification of age uncertainties.
- Calibration of the climatic and environmental signal.
- Database management
- Data processing
- Learning from other annually resolved archives
