Executive Summary

In 2005, the Heartland Inventory & Monitoring Network initiated breeding bird surveys on Herbert Hoover National Historic Site, Iowa, to address two objectives: (1) to monitor changes in bird community composition and abundance, and (2) to improve our understanding of relationships between breeding birds and habitat, and the effects of management actions on those relationships. This report evaluates trends in the park’s breeding bird populations in the context of trends observed within the North American Bird Conservation Initiative’s (NABCI) Eastern Tallgrass Prairie Bird Conservation Region , the region in which the park is located. By doing so, we …

The Long-Run Effects Of Tropical Cyclones On Infant Mortality, Isabel Miranda

Master's Theses

In the United States alone, each tropical cyclone causes an average of $14.6 billion worth of damages. In addition to the destruction of physical infrastructure, natural disasters also negatively impact human capital formation. These losses are often more difficult to observe, and therefore, are over looked when quantifying the true costs of natural disasters. One particular effect is an increase in infant mortality rates, an important indicator of a country’s general socioeconomic level. This paper utilizes a model created by Anttila-Hughes and Hsiang, that takes advantage of annual variation in tropical cyclones using annual spatial average maximum wind speeds and …

Determining The Effect Of Mission Design And Point Cloud Filtering On The Quality And Accuracy Of Sfm Photogrammetric Products Derived From Suas Imagery, Daniel Shay Hostens

MSU Graduate Theses

This research investigates the influence that various flight plan and mission design strategies for collecting small unmanned aerial system (sUAS) imagery have on the accuracy of the resulting three-dimensional models to find an optimal method to achieve a result. This research also explores the effect that using gradual selection to reduce the sparse point cloud has on product accuracy and processing details. Imagery was collected in the spring of 2018 during leaf-off conditions at six field sites along the North Fork of the White River. The aerial imagery was collected using a DJI Phantom Pro 4 sUAS. Four different image …

United States National Park Service: Publications

Rock ptarmigan (Lagopus muta) and willow ptarmigan (L. lagopus) are Arctic birds with a circumpolar distribution but there is limited knowledge about their status and trends across their circumpolar distribution. Here, we compiled information from 90 ptarmigan study sites from 7 Arctic countries, where almost half of the sites are still monitored. Rock ptarmigan showed an overall negative trend on Iceland and Greenland, while Svalbard and Newfoundland had positive trends, and no significant trends in Alaska. For willow ptarmigan, there was a negative trend in mid-Sweden and eastern Russia, while northern Fennoscandia, North America and Newfoundland had no significant trends. …

Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller

Geography ETDs

Terrain is often displayed on maps either as background or foreground. Although terrain representations are ubiquitous, there is not a thorough understanding of map-readers’ cognition of geographic surfaces from various terrain representations. The research described in this thesis empirically assessed map users’ abilities at estimating straight-line distance using maps with two different types of terrain representations and at three different scales. The objective of this research was to assess how accurately map users estimate distance on the ground taking into account variations in elevation. Participant data in the form of demographics and distance estimates were statistically analyzed to determine if …

Homelessness In Portland, Oregon: An Analysis Of Homeless Campsite Spatial Patterns And Spatial Relationships, Krystle N. Harrell

Geography Masters Research Papers

Homelessness is a complex American social issue. Understanding the homeless population, including how many people experience homelessness, how they entered the experience, their demographics, how they survive, and where they survive, aids policymakers, planners, and advocates in developing the appropriate approaches and solutions to end and prevent homelessness. Analysis of homeless spatial patterns and distributions across different locales provides a more in-depth understandings of this population and how best to support them, from the local to national level. Using geographic information systems (GIS) and statistical methods, this study examines the spatial patterns of homeless campsites and their relationship with urban …

Analysis And Conservation Of Native Forests At Kessler Mountain Fayetteville, Arkansas, Alan James Edmondson

Graduate Theses and Dissertations

Kessler Mountain in Fayetteville Arkansas has long been recognized for its beauty and natural resources. Parts of Kessler Mountain have been homesteaded and developed in the past, but most of the mountain has remained relatively undisturbed. The planned development of over 4,000 housing units to cover Kessler Mountain stimulated controversy and consideration of other management alternatives. A twist of fate involving an economic recession, a dedicated group of outdoor recreation enthusiasts, and environmental conservationists led to the permanent protection of 384 acres in the Kessler Mountain Regional Park. To help evaluate the natural resources at Kessler Mountain, forest composition, structure, …

Detecting Coastal Marsh Change From Aerial Imagery Using Spectral And Textural Methods: Pascagoula River Estuary, Mississippi, 1955-2014, Margaret Claire Bell Waldron

Master's Theses

As sea level rise accelerates, coastal marsh ecosystems are increasingly vulnerable. Vertical accretion rates must exceed or keep pace with rates of sea level rise to prevent transition to open water or inland migration of marsh vegetation. While some marsh systems along the northern Gulf of Mexico coast have remained stable, others, e.g., the marshes of the Louisiana Gulf Coast, have experienced high rates of conversion to open water. This study examined the historical extent of intertidal marsh at the mouth of the Pascagoula River in Jackson County, Mississippi to determine whether marsh extent changed during the period 1955-2014 and …

The Image From The Road: Towards Mapping The Phenomenological, Rachel Anna Smith Loerts

Graduate Theses and Dissertations

An area of focus, used in early and contemporary forms of cognitive geography research, is the ‘cognitive map’, a concept that suggests “that people hold a map-like database in their minds to which they can add and use to tackle geographical tasks”. Kevin Lynch, an urban planner in the 1960s, was an early adopter of the cognitive map approach to reveal spatial cognition, what or how people see their environment, specifically cognition of the urban environment. Lynch’s research aimed to develop empirical methods, to identify how people make spatial relationships. Contemporary tools like machine learning are now considered relevant for …

Spreadsheets-In-Space: A Quantitative Exploration Of Movement, Currency Creation, And Conflict Within Eve Online, Christopher Alan Pryor

Graduate Theses and Dissertations

EVE Online is a massively-multiplayer online game with complex interactions between players and their unique, virtual environment. These relationships are the ongoing results of a conflict-driven economy, but they vary both in duration and by location.

This study attempts to quantify the direct effects of movement and indirect effects of conflict upon economic activity in the form of currency creation and delineate how successfully these relationships can be quantified by narrower time-spans and areas. Results of the mediation models used in this exploration indicate the changing relationship between movement (Ship Jumps), conflict (Ship Kills), and currency creation (Faction Kills) is …

Geography and the Environment Capstone Projects

The University of Richmond has announced their partnership with sPower’s Spotsylvania Solar Energy Center that is to be developed in the next two years to contribute to their 2050 carbon neutrality goals. The university is supposed to have 20 MWs of the 500 MW solar development, which should produce enough energy to account for 100% of the electricity usage on campus. This will make the University of Richmond the first institution of higher education in the southeast to match 100% of its electricity needs with solar energy and will decrease the university’s greenhouse gas emissions by 60% (University of Richmond …

Shrinkage Of Tropical Glaciers In Peru, Ashley Mccracken

Student Symposium

Over the past few decades, global atmospheric temperatures have increased at an alarming rate, which has a significant impact on glaciated regions of the world. Tropical glaciers represent 1/6th of all the glaciers in the world and provide key water sources for many millions of inhabitants, including the Andes region of South America. Increasing temperatures and humidity due to anthropogenic climate change means there will be more rain and less snow, causing glaciers in the tropics to shrink – without the key inter-seasonal snow accumulation, many are expected to disappear within the next 60 years. Advances in satellite imagery allow …

La Gota Que Colma La Caguama: Cummulative Tensions Transformed Into The Defense Of Water, Anthony J. Meluso

Geography ETDs

Making water management decisions is often where dreams and visions about potential futures are constructed and contested (Swengedouw 2015). However, in a globalized world, it is not well understood how people can challenge dominant paradigms to shape desirable futures when they are also complicit in, and dependent on existing structures (Arts & Buizer 2009; Emery, Perks, & Bracken 2013: Kleinschmit, Böcher, & Giessen 2009). This project examines a brewery conflict in the Mexicali Valley that provides an example of how protesters were able to challenge dominant assumptions about water management in a complex, globalized environment. I draw on Laclau’s (2005) …

Vietnam's Natural Hazards - 1999 Flood, Vu H. Vo

Kansas State University Undergraduate Research Conference

Vietnam is one of the countries most affected by natural hazards such as flood. For instance, during the 1990s to the early 2000s, the country experienced numerous floods, particularly in its central and southern regions. Located in Southeast Asia, bordered by China in the north, Laos and Cambodia in the west, and the South China Sea in the east, the country has 2,860 small and large rivers with a total flow of about 867 billion cubic meters per year. The central region of Vietnam is narrow, mountainous, and close to the coastline. Many rivers pass through the region, which had …

United States National Park Service: Publications

Executive Summary

The Northern Great Plains Inventory and Monitoring Network includes thirteen park units located in five northern Great Plains states across six ecoregions. Two park units, Jewel Cave National Monument (JECA) and Wind Cave National Park (WICA), protect significant cave resources. These two caves are among the longest caves in the world and have an assortment of underground water resources ranging from drip sites to cave lakes. Subsurface water quantity and quality in the caves is a concern due to groundwater depletion and groundwater contamination from pesticides (aboveground applications), hydrocarbons (vehicle use and related activities), and wastewater effluent (sewage …

An Evaluation Of Sentinel-1 And Sentinel-2 For Land Cover Classification, Aaron Meneghini

International Development, Community and Environment (IDCE)

This study evaluates Sentinel-1 and Sentinel-2 remotely sensed images for tropical land cover classification. The dual polarized Sentinel-1 VV and VH backscatter images and four 10-meter multispectral bands of Sentinel-2 were used to create six land cover classification images across two study areas along the border of the Bolivian Pando Department and the Brazilian state of Acre. Results indicate that Sentinel-2 multispectral bands possess a higher overall performance in delineating land cover types than the Sentinel-1 backscatter bands. Sentinel-1 backscatter bands delineated land cover types based on their surficial properties but did not facilitate the separation of similarly textured classes. …

Analysis Of 2017 Multi-Agency Field Campaign Data For Wintertime Surface Pollution In The Cache Valley Of Utah, Gerardo Diaz Jr.

Masters Theses & Specialist Projects

Atmospheric motions resulting from rising airborne parcels help to scatter emissions, including PM, away from their sources, decreasing local pollution levels. However this pattern shifts during the wintertime, as cold air damming and inversion layers create stable conditions that limit the vertical transport of air masses. Both point and area sources of emissions currently dot the western United States and are responsible for the production of the vast majority of agricultural pollution in the region. At the same time, population-growth has resulted in an ever-increasing amount of urbansource emissions. The entrapment of PM, which are produced when a wide array …

Climatology, Variability, And Return Periods Of Tropical Cyclone Strikes In The Northeastern And Central Pacific Basins, Nicholas S. Grondin

LSU Master's Theses

Tropical cyclones (TCs) are among the most destructive meteorological phenomena and impact the lives of people who reside along the coast. The American Pacific Coastline borders the second most active TC development region in the world, the northeastern Pacific (NE Pac) basin. This region, along with the Central Pacific (C Pac)-bordering Hawaii is home to a growing population and cities engaged in a variety of economic activities, most prominently agriculture, fishing, and tourism. This study analyzes fifty-two (1966-2017) years of NE Pac and C Pac TCs through applying track data from the National Hurricane Center’s HURDAT2 and a TC size …

Vulnerability Of Industrial Facilities In The Lower Mississippi River Industrial Corridor To Relative Sea Level Rise And Tropical Cyclone Storm Surge, Joseph Blake Harris

LSU Doctoral Dissertations

Relative sea level rise (RSLR) and tropical cyclone-induced storm surge are major threats to the Lower Mississippi River Industrial Corridor (LMRIC) which has approximately 120 industrial complexes located within the corridor. Spatial interpolation methods were applied to the 2004 National Oceanic and Atmospheric published Technical Report #50 subsidence dataset and cross-validation techniques were used to determine the accuracy of each method. Digital elevation models (DEMs) were created for the years 2025, 2050, and 2075, based on these predictive surface of subsidence rates. Future DEMs were utilized to model RSLR and determine the extent of storm surge on the LMRIC by …
