Summary
This award supports the purchase of a new thermal ionization mass spectrometer (TIMS) that will advance science through high-precision measurements of chemical signatures of rocks, minerals, and sediments. These measurements will enable the documentation of changes in the oceans, atmosphere, and continents over millions of years. The studies will investigate ocean anoxic events, hydrothermal fluid evolution, continental weathering, and the environmental effects of volcanism. Documenting past environmental changes will help us to understand and refine models of future conditions. The instrument
