Descent into "Deep-Time": NSF Workshop Highlights Earth's Ancient Paleoclimate
Rock record preserves results of large-scale changes in Earth's
environment
Earth's "deep-time" rock record preserves the results of multiple
large-scale changes in the planet's environment, according to
geologists. Although studies of recent climate can be conducted
with a resolution lacking in deep-time observations, they fail to
capture the breadth of climate-system behavior, say these
geologists. Deep-time paleoclimatology encompasses the study of
Earth's history at resolutions ranging from the million-year to
millennial. Deep-time studies showcase environmental
disturbances unknown in recent periods, and feedbacks that occur
on longer time scales and in response to different perturbations
of the Earth system than those observable from recent time.
Researchers have made great strides in their ability to
reconstruct the climate of Earth's deep-time past, and resolution
and dating techniques have improved considerably, according to
earth scientists.
Significant advances in analytical techniques applicable to deep-
time climate studies now enable researchers to achieve
unprecedented resolution. Scientists working in this field will
take part in a workshop, funded by NSF, to discuss the science of
deep-time paleoclimatology and try to define the fundamental
climate system problems that can be uniquely studied and
understood in deep-time.

NSF is an independent federal agency that supports fundamental research and education across all fields of science and engineering, with an annual budget of nearly $5 billion. NSF funds reach all 50 states through grants to nearly 2,000 universities and institutions. Each year, NSF receives about 30,000 competitive requests for funding, and makes about 10,000 new funding awards. NSF also awards over $200 million in professional and service contracts yearly.
