W. M. Keck Carbon Cycle Accelerator Mass Spectrometer (KCCAMS) Facility

UC Irvine’s KCCAMS radiocarbon (14C) measurement facility is dedicated to supporting carbon cycle research. It combines the KCCAMS sample preparation laboratory that accepts samples from domestic and international researchers and three research laboratories that process samples for terrestrial/atmospheric, marine, and paleoclimate research.

Research Groups
Southon Group

John Southon

Radiocarbon (14C) measurements to support C cycle research.

Druffel Group
Faculty
Ellen Druffel

Investigate why the 14C age of marine dissolved organic carbon (DOC) is thousands of years old, despite evidence that most of it is produced in the surface ocean during photosynthesis

Czimczik Group
Faculty
Claudia Czimczik

Combines field observation with geochemical analyses to understand how climate and anthropogenic activities impact carbon cycling and storage in (Arctic) land ecosystems, air pollution, and the global carbon cycle.

Randerson Group
Faculty
Jim Randerson

Global change in terrestrial ecosystems

Terrestrial Paleoclimate and Geochemistry Group
Faculty
Kathleen Johnson

Reconstruct past climate (paleoclimate) over the past several glacial-interglacial cycles at seasonal to millennial resolution and to compare these records with other paleoclimate data and model output

Trumbore Group
Faculty
Sue Trombore

Application of radiocarbon to study the dynamics of carbon cycling in plants and soils
