Examining Arctic Melt Pond Dynamics Via High Resolution Satellite Imagery, Austin Abbott, Victoria Hill Apr 2021

Examining Arctic Melt Pond Dynamics Via High Resolution Satellite Imagery, Austin Abbott, Victoria Hill

College of Sciences Posters

The Arctic Ocean is a rapidly changing environment, and a key observational system for monitoring climate change. The Arctic is going under a rapid transition from thicker, multi-year ice, to thinner first-year ice, that may have many potential consequences. As first year Arctic sea ice begins to retreat in the spring and early summer, melting snow and ice form ponds on the surface- “melt ponds”. These melt ponds increase light transmission to the water column, resulting in warming and increased primary production under the ice. Recent advances in high resolution satellite imagery now allow us to monitor the development and ...

Using standard ambulance response times from each hospital throughout the area, our objective is to determine what proportion of Tri-County seniors aged 65 and over, including those who are in nursing homes, are living independently, and cannot afford health care, were within an adequate travel time to the hospital ...


Quantifying The Simultaneous Effect Of Socio-Economic Predictors And Build Environment On Spatial Crime Trends, Alfieri Daniel Ek Dec 2020

Quantifying The Simultaneous Effect Of Socio-Economic Predictors And Build Environment On Spatial Crime Trends, Alfieri Daniel Ek

Theses and Dissertations

Proper allocation of law enforcement agencies falls under the umbrella of risk terrainmodeling (Caplan et al., 2011, 2015; Drawve, 2016) that primarily focuses on crime prediction and prevention by spatially aggregating response and predictor variables of interest. Although mental health incidents demand resource allocation from law enforcement agencies and the city, relatively less emphasis has been placed on building spatial models for mental health incidents events. Analyzing spatial mental health events in Little Rock, AR over 2015 to 2018, we found evidence of spatial heterogeneity via Moran’s I statistic. A spatial modeling framework is then built using generalized linear ...

Examination Of Institutional Investment In The United States Of America From 1999 To 2018, Martin R. Lefebvre Nov 2020

Examination Of Institutional Investment In The United States Of America From 1999 To 2018, Martin R. Lefebvre

Electronic Thesis and Dissertation Repository

This thesis examines the evolution of spatial preference of institutional investors located in the United States of America for the time period of 1999 to 2018 using a mix of exploratory data analysis techniques and more sophisticated space-time and machine learning techniques such as ESRI Space-Time cube and Latent Dirichlet Allocation topic modeling. This thesis concludes that despite having the appearance of a footloose industry due to almost negligible fixed costs, institutional investors are attracted to highly dynamic urban centres and on the 20 year time horizon, appear surprisingly sticky in their location preference. This is consistent with the belief ...

The Use Of Green Pond Conglomerate As Building Stone In Morris County, New Jersey, Gregory A. Pope Oct 2020

The Use Of Green Pond Conglomerate As Building Stone In Morris County, New Jersey, Gregory A. Pope

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Green Pond Conglomerate (GPC) is a maroon colored quartzite with white quartz pebbles, a classic “puddingstone”. GPC derives from a NW-SW-trending sliver of Paleozoic sediments, the “Green Pond Outlier”, surrounded by older metamorphic and igneous rocks of Morris and Passaic Counties. Buildings, retaining walls, field fences, and monuments incorporate the durable and attractive stone, in a distinct geographic area of Morris County. Several instances of structures completely constructed or faced with GPC occur in and around Morristown, limited to affluent houses and one prominent church. In these cases, GPC stones were dressed and faced, a labor-intensive effort. Elsewhere in the ...

Forest Landscape Structure Influences The Cyclic‐Eruptive Spatial Dynamics Of Forest Tent Caterpillar Outbreaks, Louis‐Etienne Robert, Brian R. Sturtevant, Daniel Kneeshaw, Patrick M. A. James, Marie‐Josée Fortin, Peter T. Wolter, Philip A. Townsend, Barry J. Cooke

Natural Resource Ecology and Management Publications

A fundamental question in forest insect ecology is the role of forest landscape structure, particularly the amount and spatial configuration of host tree species, in shaping the dynamics of recurring forest insect outbreaks. For forest tent caterpillar (FTC), independent studies do not converge on a singular conclusion, although all indicate that forest structure influences outbreak dynamics. These studies also vary in how they treat climate as a covariate. We evaluated the relative importance of host forest landscape composition and configuration, as well as climate, for their influence on FTC outbreak cycling in the twentieth century. We predicted that FTC outbreaks ...

Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith Jul 2020

Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith

Theses and Dissertations

Soil microorganisms help maintain nutrient cycling, control carbon sequestration, impact plant productivity, and influence several soil chemical and physical properties; yet, the processes that control the microbial composition of soil and how environmental changes may affect the composition and activity of these organisms at different scales remains a difficult and intriguing puzzle for soil scientists, ecologists, and modelers. Wetlands are endangered and important ecosystems that provide several services, which are directly linked to soil function. However, few wetland assessments consider the soil environment and microbial ecology. Linking soil microbial community composition and distribution patterns to soil physio-chemical properties would provide ...

Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou May 2020

Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou

International Journal of Geospatial and Environmental Research

This paper presents an exploratory spatial data analysis (ESDA) of road traffic crashes at different severity levels in West Virginia (WV). Although ESDA can support transportation safety decision-making by helping planners understand and summarize crash data, it is underutilized in practice. This paper describes the application of five representative easy-to-use method to identify crash patterns and high crash-risk counties in WV. Analysis of crash data from 2010 to 2015 indicated that traffic crashes in WV were not spatially correlated. However, crash severities were found to be positively correlated.
