Donna Surge's Laboraotry houses a CM-2 Microsampler equipped with epi-fluorescence. Donna's research interests bridge the fields of paleoclimatology, paleoecology, archaeology, and low-temperature geochemistry. Recent efforts are focused on climatic and ecological archives contained in accretionary, hard-part remains of coastal marine shellfish and finfish from Holocene archaeological deposits and Neogene fossil deposits.
Jeff Dorale's Laboratory has a CM-2 equipped with epi-fluorescence, and a whole stalagmite option. Research activities involve examination of ancient climate change using stable isotope ratios and U-series dating of stalagmites.
Lowell Stott's stable isotope laboratory houses a CM-2 microsampler equipped with a whole stalagmite option. Research activities involve examination of ancient climate using stable isotope ratios and U-series dating of stalagmites.
Amy Frappier's laboratory houses a CM-2 microsampler equipped with epi-fluorescence, and a whole stalagmite option. Amy's reserach examines climate change records in tropical stalagmites. Her research activity is developing new tools for reconstructing past environmental hazards such as hurricane activity (paleotempestology) and explosive tropical volcanism (tephrochronology). Another area of exploration involves tracing the links between climate, tropical forest carbon cycling, and the sedimentary record in cave systems. Speleothem-based research is currently focused in the tropical regions of Central America and the Caribbean.

Jeff Seminoff's Laboratory houses a CM-2 with epi-fluorescence and a modified stalagmite option for use with marine mammal teeth and bones. Jeff’s current research uses innovative approaches such as stable isotope analyses, biotelemetry, and aerial surveys to elucidate the life history of sea turtles throughout the Eastern Pacific. His research has been highlighted in numerous magazines and news outlets, as well as on the Discovery Channel, Animal Planet, PBS, and National Geographic Explorer.
Pedro Marenco's Laboratory houses a CM-2 with a whole stalagmite option. Pedro's research involves the use of sedimentary and geochemical approaches to solve paleobiological problems. His research examines the sulfur and oxygen isotope ratios of materials from the Late Paleozoic icehouse to greenhouse climate transition. By using stable isotopes of sulfur preserved in brachiopods and oxygen isotopes preserved in conodonts, he hopes to better understand sulfur cycle dynamics during this important period of Earth history. Marenco continues to study seawater stable isotope geochemistry during the Permo-Triassic mass extinction and its subsequent biotic recovery by examining carbonate associated sulfate (CAS) across a Permo-Triassic boundary section in Turkey.
