A creative demonstration of the Ideal Gas Law for Summer Science Camp
students
The Reston Stable Isotope Laboratory conducts research on the use of
isotope ratio measurements in studies of water resources and environmental
quality. One objective of the RSIL project is to develop new techniques
for isotopic analysis of oxygen-bearing, sulfur-bearing, carbon-bearing,
hydrogen-bearing, and nitrogen-bearing materials. New analytical techniques
expand the range of tools available for studying the movement of those
elements in hydrologic and biogeochemical systems. Another objective
of the project is to test new applications of isotope measurements in
specific field settings. Field studies of isotope behavior have contributed
to understanding water-supply sustainability, ground-water/surface-water
interactions, paleoclimate history, biologic cycling of nutrients, ground-water
contamination, and natural remediation. This project also contributes
to the improvement of measurement science and the development of isotope
databases, as well as providing isotope analyses on a routine basis
to a large user community within the USGS and elsewhere.
