Quaternary studies focus on the processes that presently shape the natural environment and have operated over approximately the past two and a half million years (Quaternary period). A knowledge of Quaternary events facilitates an understanding of earth history in relation to the modern environment and has predictive value with regard to present-day and future environmental changes.
Quaternary research is typically interdisciplinary, and thus commonly involves related interests of two or more academic units. The Quaternary Research Center was established in 1967 to foster such interdisciplinary studies on a cooperative basis.
The center has the following goals:
Students associated with the center obtain their degrees through cooperating departments. Students interested in graduate work at the center should apply to the department of their choice but plan to do their research in a Quaternary-related subject.
QRC Resource Center
A specialized collection includes books, monographs, theses, journals, and maps; and a large, diverse reprint collection. Searches for library material can be conducted via the QRC web page.
Cosmogenic Nuclide Laboratory
Analyzes rare radionuclides produced by cosmic ray bombardment of the Earth's surface. These nuclides are useful for surface exposure dating and the study of geomorphic rates and processes. Current projects include work on Quaternary glaciations of Antarctica, Europe, and North America; dating of landslides and volcanic eruptions; and studies of erosion in both tectonically active and ancient, stable landscapes. The laboratory has sample preparation facilities and clean labs for extraction of Al-26, Be-10, and Cl-36. For additional information, visit the laboratory's website.
Analyzes of natural waters, soil, and sediment. Instrumentation includes ICP-OES, ICP-MS, laser diffraction particle size analyzer, and total organic/inorganic carbon analyzer for water samples. The library also conducts C-13 CP-MAS-NMR for natural organic and pulsed field gradient PFG-NMR for diffusion studies of water in porous media. Primary research foci are weathering, elemental cycling, and studies of permafrost soils. Current projects include investigation of biocomplexity of carbon cycling in Arctic soils in Greenland and physicochemical soil processes in Antarctica and Alaska.
Research focuses on diverse processes at the interface between glaciology and geomorphology fundamental to understanding landscapes and soils in alpine and polar regions. The laboratory does experimental research on periglacial processes with special attention to complex phenomena associated with freezing soils and rocks. The laboratory also serves as a base of support for extensive field work involving electronic instrumentation to monitor surface processes in the Arctic, Antarctica, the Himalayas, southeast Tibet, and other regions across the globe.
Stable Isotope Laboratory
The main center for stable isotope studies for the QRC. Current emphasis is development of high-resolution climate records covering the last ten millennia, from ice cores in the Canadian Arctic, Greenland, and Antarctica. Facilities include off-line and online preparation systems for D/H and 18)/16O on water 13C12C on carbonates and organic materials, and 15N/14N on nitrate and organics. Additional information is available on the laboratory's website.
