Pleistocene, Research, Interpretation, and Synoptic Mapping Project

Project Description
The U.S. Geological Survey's PRISM (Pliocene Research
Investigations Synoptic Mapping) Project is conducting
multi-disciplinary research o paleoclimatic conditions during
the middle Pliocene, the last period sustained warmth in Earth
history. Mapped paleoclimatic data from th period will be used
to validate numerical-model simulations of past climates, and
will thus aid in the improvement of these models' abili to
predict climates substantially different from that of today.
Additionally, these data may provide insights into the nature of
regional climatic patterns in a warmer-than-modern global
climate and help determine the nature, amplitude, and timing of
paleoclimatic variations within this warm period.
