Applications of Deep Learning, Machine Learning, and Remote Sensing to Improving Air Quality and Solar Energy Production
(2021)Exposure to higher PM2.5 can lead to increased risks of mortality; however, the spatial concentrations of PM2.5 are not well characterized, even in megacities, due to the sparseness of regulatory air quality monitoring (AQM) ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Ecohydrology, 2015-10-01)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Cloud-Based Remote Sensing for Conservation
(2023-04)This project aims to develop web-based landcover classification tools for Virunga National Park in Democratic Republic of the Congo, leveraging the rich information provided by Sentinel-2 multi-spectral imagery. The tool ... -
Data Driven Style Transfer for Remote Sensing Applications
(2022)Recent recognition models for remote sensing data (e.g., infrared cameras) are based upon machine learning models such as deep neural networks (DNNs) and typically require large quantities of labeled training data. However, ... -
Drone Use in Forestry 2021
(2021-12-08)In the last 20 years, advancements in technology, such as remote sensing, have facilitated improvements in forest management. The utilization of one remote sensing tool, in particular, an unmanned aerial vehicle (drone), ... -
Efficacy of Monitoring Management Activities in Longleaf Pine in North Carolina Using Remote Sensing
(2019-12-10)Using remote sensing as a tool to monitor forest management intervention may reduce the time and funds needed to actively visit landscapes. However, previous research typically studied the effects of large-scale disturbances, ... -
Evolution of Coastal Landforms: Investigating Sediment Dynamics, Hydrodynamics, and Vegetation Dynamics
(2018)Coastal ecosystems provide a wide range of services including protecting the mainland from the destructive effects of storms, nutrient cycling, water filtration, nurseries for fish and crustaceans, and carbon sequestration. ... -
Hunting for Hidden Wetlands: An Exploratory Geospatial Analysis to Identify Depressional Wetlands in the Sandhills Game Lands in North Carolina
(2023-04-27)In the Sandhills Game Lands of North Carolina, non-floodplain depressional wetlands are vital habitat for amphibian populations in conservation need. As such, it is imperative these landscape features be identified to ensure ... -
Improving population estimates of difficult-to-observe species: A dung decay model for forest elephants with remotely sensed imagery
(Animal Conservation, 2021-01-01)Accurate and ecologically relevant wildlife population estimates are critical for species management. One of the most common survey methods for forest mammals – line transects for animal sign with distance sampling – has ... -
Investigating the Eco-Hydrological Impact of Tropical Cyclones in the Southeastern United States
(2013)Tropical Cyclones (TCs) intensity and frequency are expected to be impacted by climate change. Despite their destructive potential, these phenomena, which can produce heavy precipitation, are also an important source of ... -
Land Use Land Cover in the Western Ghats, India: Effects of Human Modification and Use on Protected Areas
(2013-04-26)In India’s Western Ghats mountain range, a UNESCO World Heritage Site and Conservation International biodiversity hotspot, human-caused habitat loss threatens many native species. A number of protected areas have been created ... -
Land Use Land Cover in the Western Ghats, India: Effects of Human Modification and Use on Protected Areas
(2013-04-26)In India’s Western Ghats mountain range, a UNESCO World Heritage Site and Conservation International biodiversity hotspot, human-caused habitat loss threatens many native species. A number of protected areas have been created ... -
Mapping the Impact of Aerosol-Cloud Interactions on Cloud Formation and Warm-season Rainfall in Mountainous Regions Using Observations and Models
(2017)Light rainfall (< 3 mm/hr) amounts to 30–70% of the annual water budget in the Southern Appalachian Mountains (SAM), a mid-latitude mid-mountain system in the SE CONUS. Topographic complexity favors the diurnal development ... -
Monitoring and Forecasting Forest Drought Stress to a Changing Climate
(2017)Globally, trees are increasingly dying from extreme droughts and heatwaves, a trend that is expected to increase with climate change. Loss of trees has significant ecological, biophysical, and biogeochemical consequences. ... -
Quantifying and Elucidating the Physical Basis of Uncertainty in GPM-DPR Precipitation in Mountain Regions Using Multi-Frequency Observations and Models
(2019)Quantitative precipitation estimation (QPE) in mountainous regions remains a challenging task owing to its high spatial and temporal variability. Satellite-based radar observations at high resolution have the best potential ... -
Remote Sensing of Fire, Flooding, and White Sand Ecosystems in the Amazon
(2009)Human and natural disturbance affect the Amazon basin at several spatial and temporal scales. In this thesis, I used satellite-detected hot pixels to examine patterns of human-caused disturbance and protected areas in the ... -
Seasons in the Stream: River Ecosystem Phenology in a Changing Climate
(2023)Patterns of primary productivity are primarily dictated by seasonal factors like light availability and temperature. In small rivers, primary productivity often peaks opposite that of terrestrial ecosystems, where overhanging ... -
Shorebird response to spatiotemporal variability in non-tidal wetlands in the Sacramento Valley
(2018)Over 50% of Western Hemisphere shorebird species are in decline due to ongoing habitat loss and degradation. Many shorebird species require flooded habitat to rest and feed during migratory movements spanning thousands of ... -
