Studies of Environmental and Geologic Systems on Long Island
Prof. Hanson is a member of the Long Island Groundwater Research Institute and is pursuing studies with members of the institute on soil geochemistry, plant geochemistry and groundwater geochemistry. He is also involved in studies of the geology of Long Island. The following are MS and Ph.D. thesis research on Long Island. He was selected as Man of the Year in Science in December 2005 by The Village Times Herald, The Port Times Record, and The Times of Middle Country
- Geng Xin did a Strontium Isotope Study of the Peconic River Watershed, Long Island, New York for his MS thesis
- Sonya Boguslavsky determined the cation exchange capacity organic distribution coefficients and mineralogic composition of sediments in the unsaturated zone of Long Island for her MS thesis
- Patti Bleifuss undertook a study of the sources of nitrate in the Northport area of Long Island for her MS thesis
- Stacy Ann Lawrence used dendrochronology and the geochemistry of tree rings on Long Island to evaluate the effect of acid rain on Long Island's soils and trees for her MS thesis
- Jian Zhong used Ar-Ar ages of single grains of muscovite and biotite to determine the provenance of loess on Long Island for her MS thesis
- Vesna Kundic studied the age and provenance of loess on Long Island for her MS thesis
- Jennie Munster
used geochemistry to evaluate the source of nitrate in groundwater
in Suffolk County, New York for her MS thesis
She has also evaluated the sources of perchlorate in groundwater in Suffolk County for her Ph.D. dissertation - Linda Liu has modeled Mg, Ca, K, and Na during interaction of a sewage plume with Long Island sediments for her MS thesis
- Xuan (Sunny) Xu studied the Chemical signature of a sewage plume from a cesspool, Long Island, New York for her MS thesis
- Soma Das (Sen) studied the Origin and evolution of Dry Valleys south of Ronkonkoma Moraine for her MS thesis
- Lisha Zhou is evaluating the use of NEXRAD radar data for determining the annual precipitation patterns on Long Island for her MS thesis
- Caitlin Young is evaluating the extent of denitrification in Suffolk County Groundwater for her MS thesis
Long Island Geologists
Prof. Hanson is the coordinator for the Long Island Geologists meetings. These include the Conference on the Geology of Long Island and Metropolitan New York usually on the third Saturday in April, and usually field trips during the summer and fall.
Earth Science Research ProjectProf. Hanson is promoting research at the secondary school level through the Earth Science Research Project. The major goal of this project is to enhance the research experience in secondary level Earth Science courses. GEO 589 Research for Earth Science Teachers is offered by Prof. Hanson during the Summer Sessions. This course is intended to provide Earth Science teachers or students in the MAT in Earth Sciences program an opportunity to obtain research experience.
