Aquifers as archives of paleoclimate

Authors


Abstract

The isotopic and elemental compositions of groundwater are influenced by climatic conditions at the time of recharge and are therefore indicators of climate change. The potential of aquifers as archives of paleoclimate was discussed at a 3-day conference held at Lamont-Doherty Geological Observatory, Palisades, N.Y., from May 18 to 20. About forty scientists from nine countries attended the meeting, which was sponsored by the Northeast Regional Center of the National Institute for Global Environmental Change (NIGEC) and the National Science Foundation. Fifteen invited papers were presented, which formed the background of extensive discussions on applying isotopic methods to deriving information on climate change during the last 30,000 years from the groundwater archive.
