Quantifying Terrestrial Ecosystem Carbon Dynamics With Mechanistically-Based Biogeochemistry Models And In Situ And Remotely Sensed Data, Shaoqing Liu

Open Access Dissertations

Terrestrial ecosystem plays a critical role in the global carbon cycle and climate system. Therefore, it is important to accurately quantify the carbon dynamics of terrestrial ecosystem under future climatic change condition. This dissertation evaluates the regional carbon dynamics by using upscaling approach, mechanistically-based biogeochemistry models and in situ and remotely sensed data.

The upscaling studies based on FLUXNET network has provided us the spatial and temporal pattern of the carbon fluxes but it fails to consider the atmospheric CO2 effect given its important physiological role in carbon assimilation. In the second chapter, we consider the effect of atmospheric CO2 …

Remote Sensing Of Snow Using Bistatic Radar Reflectometry, Abi Komanduru Dec 2016

Remote Sensing Of Snow Using Bistatic Radar Reflectometry, Abi Komanduru

Open Access Theses

Snow and ice processes are a critical part of the Earth’s hydrological and climate cycles. These processes can serve as an important source of fresh water as well as a cause of flooding. Various missions have been proposed by NASA and ESA for the purpose of remote sensing of snow. This research looks at applying bistatic radar reflectometry to the remote sensing of snow water equivalent. The resulting phase offset from changes in optical path length due to reflection through snow are the primary measurements made. The research uses data from a field campaign in Fraser, CO, involving an instrument …


Teaching With Arcgis Pro, Larry Theller Nov 2016

Teaching With Arcgis Pro, Larry Theller

Purdue GIS Day

For Fall semester 2016 the ABE department moved the course ASM 540 Basic GIS from ArcGIS Desktop 10.2 to ArcGIS Pro 1.3. This software from ESRI has a completely new look and feel, (ribbon-based rather than cascading menus) and is a true 64 bit application, capable of multi-threading, and built on Python 3. After ArcGIS Desktop 10.5 is released, desktop ends and the future release will be ArcGIS Pro; so it makes sense to switch sooner rather than later. This talk will discuss some issues and some observations of that process.

Spatial Analysis Of Landfills In Respect To Flood Events And Sea-Level Rise, Benjamin S. Taylor, Songlin Fei Nov 2016

Spatial Analysis Of Landfills In Respect To Flood Events And Sea-Level Rise, Benjamin S. Taylor, Songlin Fei

Purdue GIS Day

Recently in the news, media coverage of flood events has garnered much attention due to tropical storms like Hurricane Matthew and the costly damages that resulted. Under climate change, events like sea-level rise (SLR) and flooding threaten infrastructure, which make it necessary for proper planning before, during, and after installation to mitigate risk. Studies in Austria and the UK have revealed that many landfills are located in flood zones as well as coastal areas effected by coastal erosion. In the U.S. however, there have not been publications on landfill locations related to flood events and SLR. The interest of gaining …

The Impact Of Management On The Movement And Home Range Size Of Indiana's Eastern Hellbender Salamanders, Emily B. Mccallen, Bart T. Kraus, Nick G. Burgmeier, Rod N. Williams

Purdue GIS Day

Eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) are a large, fully aquatic salamander species distributed throughout watersheds in the eastern United States. In Indiana, hellbenders were once found in tributaries of the Ohio River and the Wabash River but are now restricted to a single river in the southern portion of the state. Monitoring within the Blue River over twenty years has revealed a steady decrease in the total abundance of hellbenders and a shift towards older individuals in the age structure of the population. Concerned over the apparent lack of recruitment, the Indiana department of natural resources performed a series of …

Analyzing The Native-Exotic Richness Relationship Using Native Beta Diversity, Gabriela C. Nunez-Mir, Songlin Fei Nov 2016

Analyzing The Native-Exotic Richness Relationship Using Native Beta Diversity, Gabriela C. Nunez-Mir, Songlin Fei

Purdue GIS Day

Invasion paradox, a change of direction in native-exotic richness relationships (NERRs) from negative at small scales to positive at large scales, has been shown to exist in many environments. A major explanation for these patterns is environmental heterogeneity, and to a lesser extent, species pool size. It is likely that a combination of these factors is producing these patterns and determines if and how they appear in certain environments. Beta diversity, which describes the heterogeneity of species composition among assemblages and as the scalar between local richness and regional richness (species pool size), could serve as a proxy for these …

Mapping Religion And Chinese Society, Jonathan E.E. Pettit Nov 2016

Mapping Religion And Chinese Society, Jonathan E.E. Pettit

Purdue GIS Day

Over the past two decades, the Chinese government has enacted a series of regulations that have made the collection of geospatial data illegal, and have tried to use existing technologies (e.g., cell phone towers, online mapping programs) to avert attempts to map sensitive areas in China. This talks examines the recent work of Purdue graduate students at the Center on Religion and Chinese Society, who have developed a web-based GIS program that provides researchers worldwide a way to make and use accurate data on religious and demographic data in China.


Predicting U. S. Presidential Elections: From 1900 Until Today, Richard L. Hogan Nov 2016

Predicting U. S. Presidential Elections: From 1900 Until Today, Richard L. Hogan

Purdue GIS Day

This presentation is scheduled for the weekend before the presidential election of 2016. By then, we might all need a break from pollsters and predictions, although we still might be looking for some assurance that this will not be the end of Western Civilization as we knew it. Toward that end, a little historical perspective on presidential elections since 1900, complete with cool maps, of course, indicating partisanship by state, will illustrate several important hypotheses that the data suggest we might incorporate in our efforts to predict the future by explaining the past. Neither candidate has approved this message.

Passive Visual Analytics Of Social Media Data For Detection Of Unusual Events, Kush Rustagi, Junghoon Chae Aug 2016

Passive Visual Analytics Of Social Media Data For Detection Of Unusual Events, Kush Rustagi, Junghoon Chae

The Summer Undergraduate Research Fellowship (SURF) Symposium

Now that social media sites have gained substantial traction, huge amounts of un-analyzed valuable data are being generated. Posts containing images and text have spatiotemporal data attached as well, having immense value for increasing situational awareness of local events, providing insights for investigations and understanding the extent of incidents, their severity, and consequences, as well as their time-evolving nature. However, the large volume of unstructured social media data hinders exploration and examination. To analyze such social media data, the S.M.A.R.T system provides the analyst with an interactive visual spatiotemporal analysis and spatial decision support environment that assists in evacuation planning …


Geopolitical Implications Of The Sino-Japanese East China Sea Dispute For The U.S., Bert Chapman Jun 2016

Geopolitical Implications Of The Sino-Japanese East China Sea Dispute For The U.S., Bert Chapman

Libraries Faculty and Staff Scholarship and Research

Much analysis on Asian strategic challenges facing the U.S. has justifiably emphasized the South China Sea (SCS). This has also been reflected in 2016 presidential campaign debate on the SCS as an emerging area of U.S. foreign and national security policy concern. The East China Sea (ECS) is at least as important for the strategic interests of the U.S. and its allies given the tension between China and Japan over the Senkaku/Diaoyu islands, potential energy resources in this body of water, increasing defense spending by adjacent geographic powers, the area’s importance as a maritime international trade route, and the possibility …

A History Of African And South American Basins, Rebecca A. Bobick Apr 2016

A History Of African And South American Basins, Rebecca A. Bobick

Open Access Theses

As hydrocarbon development in Africa and South America continues to expand, understanding the geologic evolution as well as the geologic symmetry of each of the continent's coastal basins grows increasingly important. Unfortunately, there's currently no comprehensive database that contains the stratigraphic record, depositional environments, and tectonic evolution available for either Africa or South America. Therefore, the goal of my research is to create an extensive datapack and guide booklet for Africa's major sedimentary basins, complete the South America datapack that's currently being constructed, and correlate the western African conjugate basins to the eastern South American conjugate basins. To accomplish this, …
