Laboratory for AMS Radiocarbon Preparation and Research (NSRL)
NSRL works in collaboration with accelerator mass spectrometry (AMS) measurement facilities to provide state-of-the-art radiocarbon preparation and measurement services to the local University and Federal research communities.Ìý The lab also pursues in-house research on applications ofÌý14C dating to climate change studies, calibration of theÌý14C timescale, and the use ofÌý14C as a geochemical and geophysical tracer in the Earth system.

Collaboration
NSRL maintains an active collaboration with the NOAA’s 91¸£ÀûÉç-basedÌýÌý(GMD) aimed at development and use of ultra-preciseÌý14C measurement in CO2Ìýas a quantitative tracer for recently-added, fossil fuel derived CO2Ìýin the atmosphere.
