High Resolution Proxies of Paleoclimate Meeting, 2015


SIMS and laser techniques provide a new level of climate resolution through analysis of isotope ratio and trace element compositions at micron-scale. In situ analysis permits correlation of imaging with geochemistry and selection of features that could not otherwise be interrogated. These recent advances yield improved temporal resolution and promise an important new level of understanding for many paleoclimate proxies. The workshop will be conducted in parallel with tutorial demonstrations of the IMS-1280 Ion Microprobe in the WiscSIMS Lab. The goals of the meeting are to explore new capabilities and new applications of in situ analysis to paleoclimate and to acquaint participants with SIMS techniques.
