Temporally Consistent Urban-Rural Delineations For Global Urban Heat Island Monitoring, Tc Chakraborty
Temporally Consistent Urban-Rural Delineations For Global Urban Heat Island Monitoring, Tc Chakraborty
Yale Day of Data
Urbanization leads to local-scale modification of climate, particularly the urban heat island (UHI) effect - the high temperature in cities compared to their surroundings. The UHI effect is generally quantified by measuring the temperature differential between the city and its surrounding rural reference. Choices of both the city and the rural reference are prone to assumptions, which may affect, among other things, temporal variability in UHI intensity. To reduce these uncertainties, I create a global dataset of urban-rural delineations that can be used to better constrain the temporal trends in UHI intensity throughout the globe using the European Space Agency's …
Quantifying Ocean Acidification In The Geologic Record Using The B/Ca Ratio Of Planktic Foraminifera Shells, Laura Haynes
Quantifying Ocean Acidification In The Geologic Record Using The B/Ca Ratio Of Planktic Foraminifera Shells, Laura Haynes
Sustainability Seminar Series
56 million years ago, the Earth underwent a rapid climate change event called the “Paleocene Eocene Thermal Maximum” (PETM). Sedimentary records show that a massive amount of carbon was released into the atmosphere, causing ocean acidification, warming, and a widespread extinction of deep-sea organisms. Reconstructing the source and amount of carbon released during the PETM has been a major focus for paleoclimatologists as we seek to understand how the Earth system will respond to modern carbon emissions and warming. To help quantify ocean acidification at the PETM, we are using the boron content (the B/Ca ratio) of the shells of …
Studying The Glacial Melt Of Mount Baker Using Remote Sensing (1999 - 2019), Cole Fletcher
Studying The Glacial Melt Of Mount Baker Using Remote Sensing (1999 - 2019), Cole Fletcher
Scholars Week
With rising temperatures glaciers around the globe are beginning to melt. Melting of large glaciers should be concerning as they can raise the present sea-level which could potentially put near sea-level urban areas underwater. We must observe the rate at which glaciers are retreating. Mountain glaciers are a good resource to observe as they do give a clear visual of how fast glaciers are retreating. This project hopes to give a good visual representation and quantitative measurement of how much glacial melt is occurring at Mt Baker in Washington, United States, in the last 20 years. This project will use …

Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, Dylan Darter
Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, Dylan Darter
Kansas State University Undergraduate Research Conference
In our lab, I am using an X-ray fluorescence (XRF) to measure the concentrations of metals in sediments from subalpine lakes. Our goal is to measure the biogeochemical consequences of wildfires over the last 2000 years. This study looks at the elemental composition of different lake cores, and vegetation samples from areas of the “Big Burn” fire of 1910. This fire burned across several states in the Rocky Mountain region. With our XRF data we are able to see how the fire impacted the soils and how long after the fire proper soil composition can occur. This study can be …
Delineation Of Ohio River Flood Zones In Ballard County Using Remote Sensing, Nathan Rister
Delineation Of Ohio River Flood Zones In Ballard County Using Remote Sensing, Nathan Rister
Scholars Week
The purpose of this study was to use remote sensing to map flood zones in Ballard County as it correlates to the Ohio River flood gauges. This will help Wildlife managers to know which areas are most likely to be flooded by simply looking at river gauges and prevent them to having to check which areas are flooded in person. By using this technique wildlife managers will be able to save time and resources as well as better manage wildlife areas along the Ohio River.
Living In The World Of Manmade Chemicals: Lessons Learned From The Migrations And Collapses Of Civilizations, Satish Myneni
Living In The World Of Manmade Chemicals: Lessons Learned From The Migrations And Collapses Of Civilizations, Satish Myneni
Sustainability Seminar Series
Many of the world’s natural surface and groundwater resources are getting contaminated with an increasing number of manmade chemicals, which include farm and household insecticides, industrial pollutants, and pharmaceuticals. As the sizes of potable water bodies are decreasing steeply, it is warranted that we find economic ways to preserve, and purify the available water resources. In this presentation, a discussion on two of the naturally occurring and most widespread contaminants in the world and their human exposure, how one of these contaminants contributed possibly to a collapse of a thriving ancient civilization and the lessons one can learn from these, …

The Boring Millions? Vegetation, Atmospheric Co2 , And Climate Revolutions Of The Late Miocene, Pratigya Polissar
The Boring Millions? Vegetation, Atmospheric Co2 , And Climate Revolutions Of The Late Miocene, Pratigya Polissar
Sustainability Seminar Series
During the late Miocene (11-5 Ma), global ice volume and deep ocean temperatures appear to be relatively unchanging. These “boring millions” suggest stasis of the climate system with the expectation of only moderate global changes in climate, CO2 and vegetation. However, during this time tropical ecosystems underwent profound changes and surface ocean temperatures declined dramatically. When did these changes occur, what drove them, and what role if any did atmospheric carbon dioxide levels play? I will address these questions through new observations of the onset, pace and geographic extent of vegetation transformations and hydrologic changes reconstructed from molecular biomarkers. I …
