The Stable Isotope Biogeochemistry Laboratory (SIBL) at Stanford University's School of Earth Sciences provides analytical facilities and technical expertise to members of the Stanford community who need to determine stable isotope ratios of a variety of organic and inorganic materials from both terrestrial and marine environments.

The laboratory is housed in Mitchell Building (room A01 and A08) and Green Earth Sciences Building (rooms 332 and 334) located in the Science quadrangle at Stanford University. The facility has the ability to measure C, N, O (including 17O), and H in plant and animal tissue, soils, minerals, and waters. Moreover, by the use of infrared lasers and micro-drill techniques we will have the capability of high-spatial resolution isotopic measurements. Presently SIBL has seven mass spectrometers, five in Mitchell and two in Green. SIBL is overseen by Co-directors Professor C. Page Chamberlain of the Department of Geological Sciences and Professors Robert Dunbar and Karen Casciotti of the Department of Earth System Science. Operation and management of the laboratory is the responsibility of science staff members Dave Mucciarone and Peter Blisniuk and is supported by Anabelle Baya. For access to the laboratory please contact one of these laboratory managers.
