Scientists to Probe Earth's Deep-Time Climate at Upcoming "GeoSystems" Workshop
August 18, 2004
Arlington, Va.— "GeoSystems: Probing Earth's Deep-Time Climate and Linked Systems" focuses on "deep-time" millions of years ago to better understand the complexities of Earth's atmosphere, water, ecosystems, and geology, using climate as the focus.
National Science Foundation (NSF) and university scientists will participate in a workshop highlighting recent "deep-time" discoveries. Their presentations will address the status, role and future of deep-time climate and linked studies, and the lessons we can learn from shining a light into Earth's deep-time dark ages.
Aspects of our modern climate are now returning to a state last known eons ago. Understanding the ranges, rates, and processes responsible for climate extremes in those ancient times is critical for developing knowledge of our planet's climate system, and for predictions of future climate scenarios.
Recent research on deep-time is changing previous conceptions by reconstructing parameters such as atmospheric composition, sea-surface temperature, rates and modes of ocean circulation, ocean state (oxygen levels, nutrient status, biological productivity), winds, seasonality, and temperatures from records dating from tens, hundreds, and thousands of millions of years in the past. These records, scientists say, are teaching us how Earth's past climate interacted with its ecosystems, geology and water in ways previously unimagined.

The National Science Foundation (NSF) is an independent federal agency that
supports fundamental research and education across all fields of science and
engineering, with an annual budget of $6.06 billion. NSF funds reach all 50
states through grants to over 1,900 universities and institutions. Each year,
NSF receives about 45,000 competitive requests for funding, and makes over
11,500 new funding awards. NSF also awards over $400 million in
professional and service contracts yearly.
