b'Spatial Distribution of Wetlands from 1995 to 2014Amelia Cornwell, Department of Physics, Astronomy, Geosciences, and Engineering Studies Faculty Sponsor: Dr. Can Denizman, Department of Physics, Astronomy, Geosciences, and Engineering StudiesThe purpose of this study is to assess the changes in the spatial distribution of wetlands in the Suwannee River Water Management District between 1995 and 2014. Using land use layers in a GIS platform, temporal changes in wetland coverages were analyzed, and land use classes that replaced lost wetlands were determined. In addition to the wetland loss, the data were also used to calculate new wetland area. This project presents GIS as an efficient tool in analyzing temporal changes of spatial data. Landforms and Geomorphology for Chasma Boreale of Mars Northern Polar CapRichard W.A. Rickman II, Department of Physics, Astronomy, Geosciences and Engineering Studies Faculty Sponsor: Dr. Martha Leake, Department of Physics, Astronomy, Geosciences and Engineering StudiesOnce a valley and now a canyon, Chasma Boreale of the north polar cap of Mars reveals several land forms including scarps, impact craters, and barchan and linear dune fields populated with conical mounds in adjoining terrains Hyperborea Lingua, Hyperboreae Undae, and Rupes Tenuis. Seasonal climate change and aeolian processes (particularly katabatic winds) formed most of these land forms. Coriolis forces generated many spiraling chasms running parallel along the cap. Significantly, Chasma Boreale is the largest chasm at two kilometers deep, 570 kilometers long, and 120 kilometers wide. I dissected this outlier with imagery from the Viking, HiRISE, and Phoenix missions, which presented the best resolution to uncover distinctions for its amplified formation compared to other chasms. Geologic maps and Geographic Information Systems can highlight locating relevant land forms and geomorphology surrounding Chasma Boreale.60'
