Stable Isotope Biogeochemistry Laboratory
The Stable Isotope Biogeochemistry Laboratory (SIBL) within Stanford University's Doerr School of Sustainability 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.
About SIBL
The laboratory is housed in the Mitchell Building (room A01 and A06) and the 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 at natural abundance levels in a variety of materials, including in plant and animal tissue, soils, minerals, and waters. Presently, SIBL has four isotope ratio mass spectrometers (IRMS) and three cavity ring-down spectrometers (CRDS). Two IRMS are housed in Mitchell, while two IRMS and three CRDS are located in Green. SIBL is overseen by Co-directors Professor C. Page Chamberlain of the Earth and Planetary Sciences and Professor Robert Dunbar of the Oceans Department. Operation and management of the laboratory is the responsibility of science staff members Dave Mucciarone and Julie Weitzman. For access to the laboratory please contact one of these laboratory managers.
Publication Acknowledgement
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). Specifically, please include the following statement in the acknowledgment section: "The authors acknowledge the use of facilities and technical assistance of the Stanford Stable Isotope Biogeochemistry Laboratory (SIBL) Core Facility (RRID: SCR_023253)".
If any instruments within the lab were purchased using grant funds, an acknowledgment of that grant must also be included. For example, the Thermo Scientific Delta Q Isotope Ratio Mass Spectrometer (IRMS), Picarro G2201-i Isotopic Analyzer, and Aerodyne Research, Inc. TILDAS Dual Laser CH4 Isotope Analyzer were all purchased with funds from Stanford C-ShaRP, so their use must be acknowledged as follows: "The research utilized the [insert name of instrument], which was purchased with funding from Stanford University Community of Shared Advanced Research Platforms (C-ShaRP) (RRID:SCR_022986)".
Further, if SIBL staff provided 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.
