Dear All,
Vera Markgraf, Paul Baker and I are coordinating an AGU special session at
the Fall Meeting in San Francisco, December 6 to 10, 1998, on "Large Lake
Records and New Perspectives for Continental Paleoclimate Archives". The
goal of the session is to share all aspects of recovery and analysis of
sediments from large lakes throughout the world. We expect to have both
ORAL and POSTER presentations on large lakes from North America, Central
and South America (L. Nicaragua, L. Titicaca, Patagonian Lakes), from
Africa (East African lakes, Madagascar) and Asia (L. Baikal, L. Qinghai).
Here is the complete text of the session:
Large lake records and new perspectives for continental paleoclimate archives
One approach to determine the role of potential global climate forcing
factors is to correlate high resolution proxy-archives. Ice cores and
deep-sea records are traditional sources of paleoclimate information with
long temporal and spatial resolution. Continental records from non-polar
regions, however, yield information on environmental responses to climate
changes that are most pertinent to human activities. By developing and
integrating an interhemispheric network of long continental records,
evidence will emerge on the character, rate, and spatial extent of global
climate change and its forcing mechanisms.
Modern limnogeology studies large lake basins in the same fashion as
paleoceanography studies marine basins, applying similar methods and
techniques. Today there is a growing interest within the paleoclimate
community in linking marine and terrestrial records to obtain better
regional and global paleoclimatic reconstructions. Recovery of long
paleoclimate records from large lakes that cover in some cases several
glacial-interglacial cycles, provide ideal archives to accomplish this
link. Furthermore, these lake studies have recently become a major focus
of the International Geosphere-Biosphere Past Global Change Program
(IGBP-PAGES). Papers covering a wide range of aspects such as seismic
surveys of lacustrine basins, neolimnology as well as paleolimnology of the
recovered sediments are welcome from presently ongoing research projects in
large lakes all over the world.
