The Stable Isotope Biogeochemistry Laboratory (SIBL) is a Shared Analytical Resource in the Doerr School of Sustainability at Stanford University. SIBL provides analytical facilities and technical expertise for the measurement of stable isotope ratios (including C, N, O, and H) at natural abundance levels in a variety of materials, including from marine/aquatic and terrestrial environments. Presently, SIBL has six isotope ratio mass spectrometers (IRMS) and three cavity ring-down spectrometers (CRDS). Four IRMS are housed in Mitchell Earth Sciences (Rooms A01 & A08), while two IRMS and three CRDS are located in Green Earth Sciences (Rooms 332 & 334). SIBL is overseen by co-directors Professor C. Page Chamberlain of the Earth and Planetary Sciences and Professors Karen Casciotti and Robert Dunbar of the Oceans Department. Operation and management of the laboratory is the responsibility of science staff members Jen Karolewski, Dave Mucciarone, and Julie Weitzman.
For scheduling and access to the laboratory and its instruments please contact one of these laboratory managers as follows:
Jen Karolewski: For research related to samples N and O in nitrous oxide, nitrate, and nitrite
Dave Mucciarone: For research related to samples from marine/aquatic environments for isotopes, concentrations, total alkalinity, and/or total dissolved inorganic carbon
Julie Weitzman: For research related to samples from terrestrial environments

In accordance with Dean's office policy: If work done with SIBL produces data used in a publication, you must acknowledge the lab in the publication as: Stanford Stable Isotope Biogeochemistry Laboratory Core Facility (RRID:SCR_023253). Further, if SIBL staff provide significant experimental design, data interpretation, or other intellectual contribution (as evaluated by the PI), then it is expected that these individuals will be coauthors on the publication.
