The Central Appalachians Stable Isotope Facility (CASIF) is located at the University of Maryland Center for Environmental Science's (UMCES) Appalachian Laboratory in Frostburg, Maryland. The laboratory performs state-of-the-art stable isotope measurements on a variety of sample matrices.
CASIF was established in early 2010 with funds from the National Science Foundation (NSF) and UMCES. Faculty who contributed to the NSF proposal come from four institutions in the central Appalachian Mountains: the University of Maryland Center for Environmental Science Appalachian Laboratory (AL), West Virginia University (WVU), Frostburg State University (FSU), and the Canaan Valley Institute (CVI). Besides these institutions, CASIF has analyzed samples for a variety of clients at institutions including Kansas State University, North Carolina State University, University of Delaware, University of Florida, University of Maryland College Park, University of Minnesota, University of Porto (Portugal), and Virginia Military Institute.
