Radiative Forcing Over The Conterminous United States Due To Contemporary Land Cover Use Change And Sensitivity To Snow And Interannual Albedo Variability, Christoper A. Barnes, David P. Roy

GSCE Faculty Publications

Satellite‐derived land cover land use (LCLU), snow and albedo data, and incoming surface solar radiation reanalysis data were used to study the impact of LCLU change from 1973 to 2000 on surface albedo and radiative forcing for 58 ecoregions covering 69% of the conterminous United States. A net positive surface radiative forcing (i.e., warming) of 0.029 Wm−2 due to LCLU albedo change from 1973 to 2000 was estimated. The forcings for individual ecoregions were similar in magnitude to current global forcing estimates, with the most negative forcing (as low as −0.367 Wm−2) due to the transition to forest and the …

The River Discontinuum: Applying Beaver Modifications To Baseline Conditions For Restoration Of Forested Headwaters, Denise Burchsted, Melinda Daniels, Robert Thorson, Jason Vokoun

Center for Integrative Geosciences

Billions of dollars are being spent in the United States to restore rivers to a desired, yet often unknown, reference condition. In lieu of a known reference, practitioners typically assume the paradigm of a connected watercourse. Geological and ecological processes, however, create patchy and discontinuous fluvial systems. One of these processes, dam building by North American beavers (Castor canadensis), generated discontinuities throughout precolonial river systems of northern North America. Under modern conditions, beaver dams create dynamic sequences of ponds and wet meadows among free-flowing segments. One beaver impoundment alone can exceed 1000 meters along the river, flood the valley laterally, …

Using Gis To Determine Wind Harvesting Potential To Help Offset Boulder County's Yearly Energy Usage To Become A More Sustainable County, Pete Coventry

Geography and the Environment: Graduate Student Capstones

This project focuses on Boulder County, Colorado as a case study to demonstrate how a Geographic Information System (GIS) can identify potential wind harvesting areas. A step by step demonstration will illustrate the steps needed to determine such harvesting areas and their wind potential. Once potential wind harvesting areas have been identified, concluding analysis will determine the amount of energy generated in efforts to offset current energy use. Harvesting wind has dated back to the 7^th century and is looked at as a mature technology (Edwards 2003). Over the past few decades, public attitudes towards wind harvesting is becoming …

Fire Effects On Wildlife In Tallgrass Prairie, Maria Gaetani, Kayla Cook, Sherry Leis

United States National Park Service: Publications

Abstract

In the tallgrass prairie region of North America, grasslands are often burned on a rotational schedule to prevent the encroachment of woody species and maintain the vigor of plant communities. Although prescribed fire practitioners often consider the effects of fire on plant communities, the effects of fire on wildlife are also important. Practitioners as well as park visitors inquire about the effects of fire on birds, deer, and other animals of interest. Many wildlife species focus on vegetation structure in choosing suitable habitats, and fire can temporarily alter that structure. Wildlife species have varying habitat needs, and therefore, a …

Analysis Of Streamflow In The St. Croix River: A Hydrologic Model, Stephanie A. Kleinschmidt

Geography Honors Projects

This project assesses how streamflow is affected by anthropogenic changes to the environment, looking specifically at the St. Croix River Basin. In 2004 the United States Geologic Survey (USGS) published a report on streamflow in the St. Croix River at two gaging stations: Danbury and St. Croix Falls. The streamflow at the upstream station near Danbury, Wisconsin remained stable over time, while an increase was observed at the station in St. Croix Falls, Wisconsin further downstream. In order to evaluate this disparity, this project utilizes a GIS hydrologic model to analyze the factors expected to be influencing the flow rate. …

Revised Relative Abundance Estimates And Temporal Activity Of Bats At Three Great Lakes National Parks Based On Acoustic Data, Bruce W. Miller

United States National Park Service: Publications

Abstract

In this study, Miller re-analyzed acoustic bat data collected from June-August 2003 that was part of a baseline inventory of bat species in three national parks in the Lake Superior region. While the original study presented base-line data on the presence/absence of bat species in these parks, this reanalysis provides estimates of relative abundance and temporal activity of the identified species. Using a suite of recently developed acoustic analysis tools, Miller created species specific filters. This allowed parsing of calls from non-fragmented sequences and differentiate between two species, Myotis septentrionalis and Myotis lucifugus, that were combined into a …

Emergent Geographies In Green Energy, Sean Tierney

Electronic Theses and Dissertations

A consensus on climate change is spurring an energy transition, but the geography of this transition is uneven and this paper evaluates the energy landscape globally, in the United States and in Colorado. Developed countries have taken the lead in installations and of next generation energy technology ownership. Green electricity has still not achieved parity with fossil fuels, which puts their adoption in the hands of policy makers who are trying to spur innovation with minimal financial disruption. Yet the future of green electricity is in question due to weak and fragmented policy regimes, but also because of inadequate R&D …

Niobrara National Scenic River Condition Assessment, Sunil Narumalani, Gary D. Willson, Christine K. Lockert, Paul B. T. Merani

United States National Park Service: Publications

Executive Summary

Niobrara National Scenic River spans a 122-km (76-mile) long reach of the Niobrara River in rural, north-central Nebraska. The scenic river encompasses 9,338 ha (23,074 acres) of land and water, all of which is in private ownership, except for about 320 ha (790 acres). Because the scenic river does not own land, it achieves management goals by coordinating and collaborating with federal, state, and local jurisdictions and private landowners.

The central Niobrara River Valley is often referred to as a “biological crossroads” with plant and animal species representative of northern boreal forest, eastern deciduous forest, rocky mountain coniferous …

Identifying Potential Carbon Flux Responses To Shifting Hydroecological And Climactic Regimes In The Peace-Athabasca Delta, Caleb W. Light

Theses and Dissertations (Comprehensive)

The CO2 flux response of organic carbon stored in lake sediments and littoral peat contained in sensitive, northern wetlands may contribute to accelerating atmospheric CO2 concentrations. Temperature and moisture conditions are important variables that affect the rate and quantity of CO2 released to the atmosphere from organic matter stored in lake sediments and peat. Antecedent hydroecological conditions also influence the direction and magnitude of CO2 fluxes to the atmosphere in a changing environment. To better understand and characterize the role of antecedent conditions on CO2 fluxes, this study combines paleolimnological reconstructions with laboratory incubations of littoral peat and lake sediment …

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham

Masters Theses & Specialist Projects

Agriculture contamination is very common in karst systems due to the vulnerability of these aquifers. Animal waste is often spread across crop land to enrich the soil with nitrates and phosphates. Herbicides and pesticides are also applied to the crops. The transport of these pollutants through the soil and epikarst is a difficult process to monitor due to the complex, heterogeneous behavior of the groundwater as it makes its way down to the aquifer below.

An experimental site at Crumps Cave lended a unique opportunity to monitor the vadose zone at a waterfall in the cave below. A previous dye …

Flame, Furnace, Fuel: Creating Kansas City In The Nineteenth Century, Twyla Dell

Antioch University Dissertations & Theses

Though this work is a fuel and energy history of Kansas City from 1820 to 1920, it also provides a tool to describe and analyze fuel and energy transitions. The four parts follow the rise and fall of wood, coal and oil as their use grows to a peak and, in the case of wood, declines. The founding and growth of Kansas City as an “instant city” that grew from zero population to over three hundred twenty thousand in a hundred years embodies the increased use of fuels and energy in an urban setting and serves as a case study. …

Water Quality Impacts From Agricultural Land-Use In The Karst Groundwater Basin Of Qingmuguan, Chongqing, China, Ted W. Baker

Masters Theses & Specialist Projects

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into fluvial systems travelling through the subsurface in karst areas are often very similar to the concentrations arriving at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be …

Session 7 - A Comparative Geographic Analysis Of The Impact Of Scale On Hazards And Vulnerability In Industrialized Continental Lands And Small Pacific Islands, William J. Smith Jr.

International Symposium on Technology and Society

Geography, specifically scale, has significant impacts in terms of hazards and vulnerability. Small islands, such as those found in the Pacific, experience the impacts of their relatively unique geography and scale in terms of hazards and vulnerability in at least five ways: 1) Perception and communication; 2) Impact and escape from impact; 3) Technology; 4) Recovery; and 5) Socio-environmental justice. Comparative analysis in these five areas between the Pacific’s small islands and industrialized continental regions illuminates differences regarding the way hazards and vulnerability should be conceptualized in the under-treated small islands of the world. Lessons from this analysis will aid …
