Three HWS Students Present at National Conference

The Geological Society of America's annual meeting included presentations of research on Seneca Lake, the Finger Lakes Institute and Odell's Pond

(Dec. 7, 2004) GENEVA, N.Y.–Three students from Hobart and William Smith Colleges made presentations at the annual meeting for the Geological Society of America in Denver last month. The three are all geoscience majors working with HWS Associate Professor of Geoscience John Halfman.

Senior John W. Riina, from Ridgewood, N.J., gave a presentation titled “A Hydrogeochemical Study of a Water Retention Basin, Odell's Pond.” Riina initiated a baseline hydrogeochemical survey of Odell's Pond, a manmade basin on the HWS campus, routinely taking samples from the pond. He analyzed the samples for dissolved nutrients, conductivity, major ions, alkalinity, total suspended solids, pH and dissolved oxygen. Riina compared the summer and winter data to determine the effect of winter road salt and snow melt.

Junior Clare Morgan, from Delmar, N.Y., presented on “Preliminary Hydrogeochemical Budgets for Seneca Lake, N.Y.” She obtained weekly samples of Seneca Lake in non-winter months to construct a preliminary hydrogeochemical budget for calcium, magnesium, chloride, sodium and sulfate concentrations.

Senior Douglas Wood, from Burdett, N.Y., presented on “A Practical, Trailerable Limnological Research Vessel for the Finger Lakes Institute.” The Finger Lakes Institute at HWS, dedicated to environmental research and education about the Finger Lakes, converted a stock pontoon boat into a capable research platform that can be towed overland and launched from a typical boat ramp. The vessel, JB Snow, is a complement to the Colleges' 65-foot research vessel The William Scandling. The JB Snow has the ability to collect limnological data, detailed bathymetric data, sediment samples and deploy and/or tow geophysical and other remote sensing equipment.

Halfman, who is the director of environmental studies, came to the Colleges in 1994. He holds a B.S. from Miami, an M.S. from Minnesota, and a Ph.D. from Duke University.

The Hobart and William Smith science departments and environmental studies program encourages students to involve themselves in research projects with paper presentations beyond the HWS campus.
