Hurricane Surge Inundation And Critical Resources In Maine, Brian Lynch ('09)
Hurricane Surge Inundation And Critical Resources In Maine, Brian Lynch ('09)
Atlas of Maine
This map shows projected hurricane surge inundation, often referred to as storm surge, for hurricanes ranging in severity from Category 1 to Category 4 as well the locations of critical societal resources such as fire stations, hospitals, emergency management offices, and roads. Storm surge is caused by the force of a hurricane displacing water as it moves into shallower water. According to the National Hurricane Center, storm surge is responsible for 90% of hurricane-related fatalities in the US (http://www.nhc.noaa.gov/pastdeadly.shtml). In addition, the flooding caused by storm surge may hinder evacuation as well as incapacitate or reduce the capabilities of certain …
Atlantic Salmon Habitat And Dams In Maine, Francis Gassert ('11)
Atlantic Salmon Habitat And Dams In Maine, Francis Gassert ('11)
Atlas of Maine
This map details Atlantic Salmon habitat within the state of Maine in conjunction with dams, levees, and other hydrological impoundments. It highlights salmon spawning and rearing areas, and represents dams by their hydraulic height. Most Atlantic Salmon populations are anadromous, living most of their lives at sea and migrating upstream into freshwater to spawn. However, the Atlantic Salmon does not require saltwater to survive, and there are a number of landlocked populations of Atlantic Salmon in Maine due to the building of dams.

Wind Turbine Visibility On The Colby Campus, Emma Balazs ('09), Jenny Helm ('11)
Atlas of Maine
This project was designed to demonstrate the visibility of potential future wind turbines built on the Colby campus. We conducted viewshed analyses in ArcGIS on three different potential turbine sites to determine the visibility of the turbines within a 10km radius. We found that the Runnals hill turbine would be visible to the largest area and the largest number of residents.
Possible Migration Routes Through Maine By Vernal Migrants, Andy Mcevoy ('09), Gordon Padelford ('11)
Possible Migration Routes Through Maine By Vernal Migrants, Andy Mcevoy ('09), Gordon Padelford ('11)
Atlas of Maine
In this study we evaluate the possibility of two routes of migration into the state of Maine. The first possible route would be for migrants to continue along the coast, north of the Maine/New Hampshire border, and later swinging inland across the interior. The second path is for migrants who come up the east coast and straight into Maine, spreading across the state as they move north. In order to evaluate these possible routes we utilize a citizen-science project that measures the spring arrival dates of migrants according to the biophysical regions of Maine (Wilson 2007). Independent t-Tests and maps …

Invasive Aquatic Invasion: The Spread Of Variable Leaf Milfoil In Maine, Brian Lynch ('09), Kaggie Orrick ('10)
Atlas of Maine
Variable leaf milfoil, Myriophyllum heterophyllum, has been present in Maine since 1970. We created an analysis area including seventeen infestation sites and all bodies of water within a forty mile buffer. We also eliminated all water locations with a size less than 7,101 km2, the size of the smallest infestation site, Shagg Pond. Within those specifications we randomly selected seventeen un-infested bodies of water and used them as our uncontaminated sample. We looked for relationships between presence and number of boat launches, and proximity to a populated area. Using the Mann-Whitney test, we compared the sample size of non-infested lakes …
Exploring The Spatial Relationships Between Human-Tiger Conflicts In Peninsular Malaysia And Sumatra, Aurore Anastassiadis ('11), Li Yu Chan ('11)
Exploring The Spatial Relationships Between Human-Tiger Conflicts In Peninsular Malaysia And Sumatra, Aurore Anastassiadis ('11), Li Yu Chan ('11)
Atlas of Maine
Large-carnivores and humans are increasingly in conflict as humans encroach on their natural territory. As a result, many large-carnivore species have become endangered due to habitat destruction, prey reduction and retaliatory killings from conflicts. No global internet database, however, exists to document, monitor and evaluate these conflicts, particularly to take advantage of the growing spatial resources available. Using human-tiger conflicts in Malaysia and Sumatra as a case study, this project explores how such a database could be created. GIS was used to conduct multiple analyses on the data obtained about these conflicts. We conclude that a database would require data …

Light Coverage On Colby College Campus, Meghan Cornwall ('11), Francis Gassert ('11)
Atlas of Maine
Outdoor lighting is an essential component for nighttime safety on college campuses. Outdoor lighting on Colby College campus is not uniform, leaving some areas with minimal light. The purpose of this project is to analytically evaluate if and where major walkways on Colby College have inadequate lighting. While we were unable to define inadequate lighting, we found that most paths on campus do appear to be well lit, while in general open spaces on campus have the lowest light levels.
Wind Power In Maine: Balancing Conservation And Energy Production, Hannah Lafleur ('11), Jordan Schoonover ('10)
Wind Power In Maine: Balancing Conservation And Energy Production, Hannah Lafleur ('11), Jordan Schoonover ('10)
Atlas of Maine
An expedited permitting area has been created to facilitate the development of wind power projects in Maine. The purpose of this project was to investigate the impact of removing areas of conservation interest from the expedited permitting area. We found that the removal of these areas impacts the total wind potential of the state, in an amount proportional to the size of the area removed. The impact on the total wind potential ranged from 0.46-29.0% decrease, depending on the calculation scenario used. These findings may have implications for future policy decisions concerning wind power development.

Impervious Surfaces Of Maine, Courtney Larson ('08)
Impervious Surfaces Of Maine, Courtney Larson ('08)
Atlas of Maine
Impervious surfaces include objects like buildings, roads, parking lots, and other surfaces that water cannot pass through. Pervious surfaces are mainly natural areas, such as forests and wetlands, but can also include human-modified areas such as cropland. The spatial pattern of impervious surfaces is closely tied to that of developed areas and it can therefore be used as a surrogate variable for development.
Fragmentation And Clearing Of Maine Forest Habitats, 2005, Lindsay Dreiss ('09)
Fragmentation And Clearing Of Maine Forest Habitats, 2005, Lindsay Dreiss ('09)
Atlas of Maine
The purpose of this map is to convey the extent of fragmentation in Maine's forests. I chose this particular area to show the immediate effects of logging roads and clearcutting on a local scale. The data were used to focus on current, cleared, and regenerating forest locations as of 2005. A raster layer from the National Atlas database of National Land Cover Data assesses the magnitude of forest fragmentation due to human activities. Roads were also included to emphasize the development of roadways as a cause of fragmentation.

Modeling Potential Tiger Habitat In Hupingshan-Houhe And Mangshan-Nanling National Nature Reserves, China, Charles Carroll ('08), Courtney Larson ('08)
Atlas of Maine
After declining steadily for several decades, the South China tiger (Panthera tigris amoyensis) is now thought to be extinct in the wild. However, there is some hope of reintroduction, with Hupingshan-Houhe and Mangshan-Nanling National Nature Reserves in southern China seeming to hold the most promise. Our study used slope, elevation, vegetation, and landcover variables to construct a rough habitat suitability index for tigers in these two parks. According to our model, there are areas of suitable habitat within both parks. However, there are some important variables that we were unable to include in our model, such as human population density …

A Visibility Analysis Of The Cape Wind Project, Patrick Roche ('09), Caitlin Casey ('09)
Atlas of Maine
Cape Wind has proposed a wind farm of 130 turbines on Horseshoe Shoal in the center of Nantucket Sound. A prominent concern about the project is the impact the visibility of the turbines will have on the region's tourism industry and property values. It is feared that their presence will diminish the value of the pristine coastline that has attracted vacationers to Cape Cod for generations. In this project, we assess the extent to which Cape Cod, Martha's Vineyard, and Nantucket will be visually affected by the wind farm. It was completed using a Viewshed Analysis in the GIS program, …

Demographics Of Natural Disaster Hotspots In Maine, Lindsay Dreiss ('09), Caitlin Dufraine ('09)
Atlas of Maine
Natural disasters can cause extensive damage to communities and infrastructure. The state of Maine is fairly lucky because natural disasters are relatively infrequent. Maine does, however, experience earthquakes, flooding, hurricanes, and landslides. Certain areas of the state are more prone to experience natural disaster than others. Using GIS analysis, we are analyzing natural disaster hotspots in Maine to determine if there is a statistically significant relationship between natural disaster susceptibility and socioeconomic variables including income and population.

The Carbon Emissions Of The Boston Red Sox, Rosalind Becker ('08), Alaina Clark ('08)
Atlas of Maine
The Boston Red Sox emit a great deal of carbon throughout the regular baseball season because of flights to the home fields of their opponents. Knowing that air travel is one of the biggest transportation-based contributors to global climate change, the Boston Red Sox (and all major league teams) should be encouraged to offset their carbon emissions from regular season travel. Using ArcGIS to map the flight paths along great circle routes, the distance of flights to opponents’ cities was calculated to total the number of miles traveled in the 2008 season. The price of offsetting this carbon was estimated …
