Andrea Lini, Associate Professor (Stable isotopes, Limnology and Climate Change): The UVM Mudslingers wrapped up the trophic history of Lake Champlain project. Some of our results appeared in the Journal of Great Lakes Research this past spring (The eutrophication of Lake Champlain's northeastern arm: Insights from paleolimnological analyses). Journal of Great Lakes Research 38 (2012) 35–48. Another manuscript discussing study sites from the Main and South Lake sections was submitted the end of last year.

This Mudslinger is teaching two sections of UVM Geology 001 Summer courses.

I briefly mentioned bear and wolves in the last newsletter… Well, the hair samples, along with samples from a variety of other critters (including house cat and fisher) have arrived to the lab. Although this project has nothing to do with Geology, it is an exciting one, and after the first series of tests I can report that fisher do not appear to be eating as many cats as commonly believed. Good news, I guess!

Char Mehrtens, Professor (Stratigraphy, Sedimentation, Carbonate Petrology):

I look forward displaying the permanent installation of Vermont Bedrock Map in the Perkins Geology Museum, and I plan for another summer of camping and kayaking when not writing or researching.

Keith1x1Keith Klepeis, Professor (Structural Geology and Tectonics) Keith and his students are working up the results of a recent month long geological expedition to Fiordland in the southwest New Zealand that took place in January (2013). Fiordland is a remote, mountainous rain forest (up to 13 meters of rain annually!) that exposes fragments of Earth's crust that have been exhumed from unusually deep levels (60 km depth). They are using these exposures to determine how large mountain ranges collapse and are destroyed by tectonic processes.

Keith also supervised five undergraduate theses on different elements of Vermont's geological evolution. Several of these students have been accepted to national graduate programs, including Stanford (Abi Ruksznis) and Idaho State (Doug MacLeod).

Webb1x1Laura Webb, Assistant Professor (Igneous petrology and Geochronology) Laura Webb and Patrick Dyess (Geology MS) are investigating trace element signatures of quartz in Vermont rocks as a record of temperatures and pressures attending rock deformation during ancient collisions. Laura and Dan Jones (laboratory research technician) will be commissioning the new noble gas mass spectrometer laboratory over the coming months, and Laura will be co-convening a session on "Innovations in Geochronology: Present "Developments and a Vision for 2020" at the Goldschmidt Conference this summer in Florence, Italy.

Paul_colorPaul Bierman, Professor (Geomorphology, Geohydrology, Isotope Geology Applied to Landscape Change):Paul's had a busy spring teaching 200 students in Earth Hazards, presenting Greenland research at the European Geoscience meeting in Vienna, and working with numerous graduate students, including visitors from Brazil and UConn in the cosmogenic laboratory. In addition. he's been editing final proofs for his new textbook, due out this summer, published by Freeman, and supported by a grant from NSF, Key Concepts in Geomorphology. Below are some websites related to my activities and recent publications.

Steve_colorStephen Wright, Senior Lecturer (Glacial geology, Geomorphology, Environmental Geology):
I've been on sabbatical this last year and have been engaged in a number of projects. Last summer I finished mapping the Pico Peak Quadrangle in the early part of the summer and led another group of UVM students out to Colorado during the first 3 weeks of August. Following that I had a nice long field season in the central and southern Green Mountains mapping glacial striations over a wide area. I spent the winter months working with those data and made two presentations at the Northeast Geological Society of America meeting in Bretton Woods New Hampshire. Most recently I've just returned from a month in northern England. I spent a little more than a week in the Lake District with my wife and then spent another 2 weeks walking from the west coast of England to the east coast along the Coast to Coast path. Lots of cold, windy, rainy weather, but I had good days too and was able to experience many different landscapes along this cross-section of northern England. I'm looking forward to another summer field season in Vermont and will be back in school this coming fall.

Andrew Schroth, Research Assistant Professor (Low Temperature Geochemistry, Limnology and Oceanography) I have continued my research on the biogeochemistry of glacial river, aerosol and coastal systems in Alaska, as well as new work studying nutrient biogeochemistry in the Lake Champlain basin. We have continued to collect water and sediment samples from Lake Champlain throughout the winter, and just last week successfully redeployed our biogeochemical research station in Missisquoi Bay for the 2013 field season. I am looking forward to advising my first MS student through the department's graduate program, Braden Rosenberg(Middlebury 10'), who will conduct thesis work studying micronutrient geochemistry in watersheds of Vermont and Alaska.
