Hi, I'm Dave Gosselin, a professor of Earth science in the School of Natural Resources. I am also the sirector of UNL's environmental studies program, which currently serves more than 100 undergraduate students. Over the past 15 years, developing educational programs in the area of Earth systems science has become my passion. My work in Earth systems science education started by providing professional development opportunities for K-12 educators as the director of the Nebraska Earth Systems Education Network (NESEN). The NESEN theme is to create a community among Earth science educators and scientists. For more information on NESEN, please see our homepage at https://nesen.unl.edu. My work with K-12 educators has involved traditional classroom teaching, summer workshops, and most recently the delivery of online, distance-delivered courses, as part of the Laboratory Earth professional development series. In 1999, I received the Catalyst Award from the Nebraska Association of Teachers of Science, a group that works closely with NESEN.
The common theme among my research activities throughout my career has been geochemistry, water-rock interaction and fluid migration. Most recently, my work has emphasized understanding the occurrence of arsenic and uranium in public water supplies and trying to develop a more economic approach to dealing with this water quality issue. I have also worked to understand the relationship between groundwater and surface water. In this context, I have been involved in physical hydrogeologic investigations, groundwater-lake modeling, and the use of remote sensing to study variability in lake behavior over large geographic areas.
Since getting my Ph.D., my research has evolved from working in high-temperature environments to low-temperature surface and groundwater systems. My low temperature work has involved the application of major ions, rare earth elements, radiogenic isotopes, natural uranium, thorium radionuclides, and the stable isotopes of oxygen and hydrogen, to assess the history of groundwater movement through geologic materials.
My doctoral research emphasized the Archean rocks in the Black Hills of South Dakota, and focused more specifically on elemental behavior and fluid migration at mid-crustal levels. My interest in remote sensing evolved out of my work on planetary materials, and colleagues using remotely sensed planetary data sets.
