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. The lab also pursues in-house research on applications of 14C dating to climate change studies, calibration of the 14C timescale, and the use of 14C as a geochemical and geophysical tracer in the Earth system.

Collaboration
NSRL maintains an active collaboration with the NOAA’s Boulder-based Global Monitoring Division (GMD) aimed at development and use of ultra-precise 14C measurement in CO2 as a quantitative tracer for recently-added, fossil fuel derived CO2 in the atmosphere.
