Current Research and Recent Student Thesis Projects
Svalbard, Norwegian high arctic
Since 2003, I’ve participated in the Svalbard REU: Holocene and modern climate change in the Norwegian High Arctic sponsored by the U.S. National Science Foundation Office of Polar Programs. Each year, my colleagues Al Werner (Mt. Holyoke College) and Steve Roof (Hampshire College) and I recruit 6 motivated and talented undergraduate students for the 5 week summer research program which focuses on monitoring modern glacial, fluvial and lacustrine processes and investigation of detailed lacustrine paleoclimate records. The glaciated high arctic study site in west Spitsbergen is located at 78o at the northern end of the North Atlantic current, a sensitive area for detecting and monitoring changes in the cryosphere, the frozen part of the planet. The Linnedalen study site is well equipped with instrumentation from the top of the glacier to the bottom of the lake and includes weather stations, glacier stake network, time lapse cameras and arrays of instrumentation in the lake, all designed to detect timing and nature and changes in seasonal cryospheric processes.
Shetland Islands, U.K.
My research in the Shetland Islands is part of an interdisciplinary geo-archaeology project that is investigating the occupation and abandonment of a 17th century farmstead. The site was likely abandoned in the late 17th Century, overtaken by thick windblown coastal sand deposits during one of the most stormy decades of the Little Ice Age. My students and I are working on reconstructing a continuous paleoclimate/paleoenvironmental record from lake (loch) sediment records recovered by coring lochs in the vicinity of the Broo township. My students and I are conducting detailed studies of the physical, biological and geochemical contents of the sediment cores to determine the nature and timing of climatically and environmentally significant events in the last millennium.
Bates is located just south of “the lakes region” in south central Maine. We have undertaken projects with students in courses and thesis research on many lakes ranging from coastal “isolation basin” lakes that were formerly depressed below sea level to density stratified lakes that contain laminated sediments that archive high resolution sediment records. Two current projects underway are on Basin Pond in Fayette and Round Pond, Chain of Ponds Township.
These ponds are unique–preserving detailed paleoenvironmental records with annual resolution in finely layered deposits, similar to tree rings.
Maine coastal monitoring
Geology faculty and students have long utilized the Bates Morse Mountain Conservation area
for geological research on the undeveloped barrier beach system. In 2009 we began a more intensive monitoring program on beaches in the Phippsburg area, in partnership with the Small Point community and Popham Beach State Park. The focus of the beach research is to monitor and evaluate the response of the sandy beach systems to changes brought about by storms, seasonal wave climate and rising sea level. Beach profiles and dune fronts are monitored using high resolution GPS, total station and traditional auto-level surveys in addition to time lapse photography from cameras installed at two of the beaches.
We have developed a Coastal Environmental Archive in collaboration with the community at Small Point. This archive will continue as an ongoing project designed to document change in the Maine coastline. Highlights of the archive include a collection of relevant undergraduate senior theses, satellite and air photographs, and a collection of historical photographs donated by the Small Point residents.
