> John Andrews, Geoff Seltzer and I are convening a theme session for
> the upcoming GSA annual meeting in Denver (Nov. 7-10, 2004). The
> theme session (T96) is entitled Records of Late Quaternary Climatic
> Change from the Americas: Interhemispheric Synchroneity or Not?
> We seek papers (in oral and poster format) that review high-resolution
> physical, chemical, and biological archives of climate change during
> the past ~30,000 years from the Americas, and also including Antartica
> and Greenland. Our focus is mainly on terrestrial evidence, but we
> also welcome near-shore marine records that directly record
> terrestrial events.
> Rationale for the session.
> Understanding the interregional and interhemispheric timing and
> magnitude of late Quaternary climatic change is critical for
> identification of the underlying driving mechanism(s) of global
> climatic variability. Several recent publications have highlighted
> disagreements in the scientific community over interregional leads and
> lags in the climatic system. In some regions of the globe,
> deciphering the relative roles of temperature and moisture balance are
> still problematic, and differences in the magnitude of climatic change
> as recorded in terrestrial and marine proxies have been difficult to
> resolve. In general, geochemical archives (e.g., stable isotopes)
> have provided the most quantitative records of past climatic
> conditions, but physical and biological records provide important
> constraints in climatic reconstructions and timing.
> For this GSA theme session, we would like to assemble a
> transect of paleoclimatic archives (in oral and poster format) that
> extend from Antarctica through the Americas and into Greenland. This
> would provide a broad perspective based on the most current data sets
> from these regions. We anticipate that this session will provide
> insight into interregional and interhemispheric climatic change, and
> will help to identify regions and/or methodologies that warrant
> special attention for future work. This theme session is likely to
> engender lively discussion, and we anticipate that it will attract
> both a large audience and, through our list of national and
> international invitees, the attendance of some scientists who do not
> normally attend GSA meetings.
> Please forward this message on to any/all interested colleagues
> and students. We hope to see you in Denver!
