Description:

The Reston Chlorofluorocarbon Laboratory of the US Geological Survey provides "provides analytical services for CFCs, sulfur hexafluoride, dissolved gases including nitrogen, argon, methane, carbon dioxide, oxygen, and helium, and administers the USGS contract for tritium/helium-3 dating." Scientists can learn about the USGS's research activities related to these services in Chesapeake Bay, Mirror Lake, Shenandoah National Park, and many other locations around the United States. Students and educators can find tips for sampling CFCs, SF6, dissolved gas, and tritium / Helium-3. The website, which is viewed best using Microsoft Internet Explorer, also offers a model for calculating and presenting environmental tracer data.
