Two archaeological excavations for the University of Southern Maine collected sediment columns from select units for geological and chemical analysis. The Spiller Farms site is a Native American site located in Wells, Maine marking a transition period between the Pleistocene and Holocene epochs, 12,000 BP. The Malaga Island site was a historic mixed-race community at the north end of Casco Bay where sediment columns were obtained in near-shore and subtidal zones. The samples obtained from Malaga Island have been radiocarbon dated to 3800 +/- 30 BP at 23 meters below the low-tide line. X-ray fluorescence (XRF) analysis is being conducted …

The goal of this research was to evaluate the extent of land use change occurring in the Sebago lake watershed of southern Maine. The primary data set used was Landsat 7 Near Infrared satellite imagery of the region which was analyzed with ESRI’s ArcGIS soQware. Data was clipped to the Portland Water District’s sub watershed shape file and analyzed with the soQware’s image analysis ‘difference’ tool which calculates the differences in pixel values between to raster datasets. The 2013 Landsat reclassifica-on was compared to 1987, 1995 and 2009 reclassifica-ons. NOAA’s Habitat Priority Planner plugin tool was also u-lized in order …
