PLIOCENE PALEOPRODUCTIVITY AND ICE DYNAMICS IN THE WEDDELL SEA: ODP SITES 693-695

What:  The overarching goal of this study is to improve our understanding of ice dynamics, glacial history and paleoproductivity of the Pliocene Weddell Sea using sediment cores from ODP Sites 693 and 695. Who: Suzanne O’Connell, 4 Students When: early/mid- June to early/mid-July Where: Students will spend the first week to ten days at the […]

TRACE METAL SUBSTITUTION IN AND RELEASE FROM SECONDARY IRON (OXY)HYDROXIDES

What: This project is motivated by the objective to better predict the bioaccessibility of trace metals in the environment. Students will collect samples of iron (oxyhydr)oxide precipitates and water from an abandoned mine site, synthesize pure and trace metal substituted Fe (oxyhydr)oxides, and conduct simple leach experiments with synthesized minerals. Students will also use thermodynamic […]

THE NEWBERRY CRATER LAKES, OREGON

What: The two Newberry Crater lakes are located at ~ 2 km elevation inside the Newberry Volcanic Monument area, which is located behind the Cascadian arc in the OR high desert, ~30 km south of Bend, OR. The lake waters are carbonate-rich, with neutral to slightly alkaline pH. Both lakes have subaqueous inputs of volcanic […]

HOLOCENE ENVIRONMENTAL CHANGE AND HUMAN IMPACTS IN SOUTHERN NEW ENGLAND

What: The 2015 southern New England Keck project will investigate Holocene and Anthropocene sediments and landforms to understand the regional history of floods, climate change and human impact.  We will focus on targeted long-timescale (Holocene) sediment archives within major watersheds in the region (Housatonic, Connecticut, Thames) as well as detailed studies in small basins where […]

CONSTRAINING PROCESSES IN NATURAL & EXPERIMENTAL BASALTIC LAVA FLOWS

Participants will investigate the behavior and morphology of basaltic lava flows from two very different but related perspectives: field observations of basaltic lava flows in Iceland and large-scale lava flow experiments conducted at Syracuse University. Experiments will be designed to constrain the factors that control various features found in the natural lavas. What: The project […]

ALBIAN TO CENOMANIAN (CRETACEOUS) SEDIMENTOLOGY, STRATIGRAPHY, AND PALEOECOLOGY OF AN ARCTIC FORELAND BASIN, NORTH SLOPE, ALASKA

What: Arctic Alaska experienced great tectonic and climatic change during the mid to Late Cretaceous.  We will document the sedimentary, pedogenic, and biologic responses to these changes by measuring stratigraphic sections of thick marine, deltaic, and alluvial sediment of the Nanushuk Formation exposed in synclines found in the northern foothills of the Brooks Range.  Analysis […]

EXHUMATION AND TECTONIC SIGNIFICANCE OF THE WOOD HILLS-EAST HUMBOLT RANGE METAMORPHIC CORE COMPLEX, NEVADA

What: This project will document the kinematics and thermal evolution of middle and lower crustal rocks exposed during exhumation of the Ruby Mountains-East Humboldt Range metamorphic core complex (RM-EHR) in northeastern Nevada. Although the RM-EHR is widely recognized as a classic metamorphic core complex, debates persist about the timing and kinematics of crustal extension. Students […]
