Evaluating Spatial Variability Of Precipitation In Kentucky With Exploratory Data Analysis, Daniel Taylor

Masters Theses & Specialist Projects

Spatial variability of precipitation is examined over the state of Kentucky and surrounding areas. The study focuses on the analysis of monthly precipitation totals from the period of 1961-2000. The purpose of the study is to develop a set of indices to represent the spatial variability of the study area for a given month. Various exploratory data analysis methods such as variography, kriging, and cluster analysis were used. The study attempts to quantify the second order (local) effects of the spatial variation of precipitation as a means to provide insight into the prediction of precipitation randomness. This task can be …

An Interactive Learning Environment For A Dynamic Educational Digital Library, Ee Peng Lim, Dion Hoe-Lian Goh, Yin-Leng Theng, Eng-Kai Suen

Research Collection School Of Computing and Information Systems

GeogDL is a digital library of geography examination resources designed to assist students in preparing for a national geography examination in Singapore. We describe an interactive learning environment built into GeogDL that consists of four major components. The practice and review module allows students to attempt individual examination questions, the mock exam provides a simulation of the actual geography examination, the trends analysis tool provides an overview of the types of questions asked in previous examinations, while the contributions module allows students and teachers to create and share knowledge within the digital library.

A Spatial Analysis Of The Impact Of Development On Wetland Habitat In Mount Pleasant, South Carolina, Jenna Medlin

Masters Theses & Specialist Projects

In response to growing concerns over wetland habitat loss and the associated impact on water resources, federal and state legislation has been enacted to protect vulnerable wetland habitats from the impacts of humans. In order to examine the efficacy of current coastal resource policy and its implementation, a study was conducted in Mount Pleasant, South Carolina, a coastal city of the Atlantic, focusing on the quantification of wetland habitat change over time within a specific area of interest. The study incorporated an assessment of the effects of escalating population pressures and subsequent urban development on local wetland habitats due to …

A Volumetric Assessment Of Ancient Maya Architecture: A Gis Approach To Settlement Patterns, Kathryn Sorensen, Jeffrey Glover, Scott L. Fedick

Geosciences Faculty Publications

This paper will discuss the general applications of GIS technology to our research in the Yalahau Region of northern Quintana Roo, Mexico. In particular we will address the use of a volumetric analysis as a means of developing an architectural comparative framework at both the intrasite and regional scales. The comparative framework is a powerful tool that allows us to investigate and visualize the distribution of social power both within the site of T'isil and across the region. The direct relationship between social power and architectural volume is predicated on the assumption that actors who utilized the largest dwellings were …

Hydrochemical Variations During Flood Pulses In The South-West China Peak Cluster Karst: Impacts Of Caco3–H2o–Co2 Interactions, Chris Groves, Zaihua Liu, Daoxian Yuan, Joe Meiman, Guanghui Jiang, Shiyi He, Qiang Li

Earth, Environmental, and Atmospheric Sciences Faculty Publications

High-resolution measurements of rainfall, water level, pH, conductivity, temperature and carbonate chemistry parameters of groundwater at two adjacent locations within the peak cluster karst of the Guilin Karst Experimental Site in Guangxi Province, China, were made with different types of multiparameter sonde. The data were stored using data loggers recording with 2 min or 15 min resolution. Waters from a large, perennial spring represent the exit for the aquifer's conduit flow, and a nearby well measures water in the conduit-adjacent, fractured media. During flood pulses, the pH of the conduit flow water rises as the conductivity falls. In contrast, and …

Satellite Evidence Of Hurricane-Induced Phytoplankton Blooms In An Oceanic Desert, S. M. Babin, J. A. Carton, T. D. Dickey, J. D. Wiggert

CCPO Publications

The physical effects of hurricanes include deepening of the mixed layer and decreasing of the sea surface temperature in response to entrainment, curl-induced upwelling, and increased upper ocean cooling. However, the biological effects of hurricanes remain relatively unexplored. In this paper, we examine the passages of 13 hurricanes through the Sargasso Sea region of the North Atlantic during the years 1998 through 2001. Remotely sensed ocean color shows increased concentrations of surface chlorophyll within the cool wakes of the hurricanes, apparently in response to the injection of nutrients and/or biogenic pigments into the oligotrophic surface waters. This increase in post-storm …

An Unusual Lava Cave From Ol Doinyo Lengai, Tanzania, Donald A. Mcfarlane, Joyce Lundberg, Frederick Belton

WM Keck Science Faculty Papers

A new type of lava cave is described from the summit crater of Ol Doinyo Lengai, a unique active carbonatite volcano in Tanzania. This and other similar caves on Ol Doinyo Lengai are formed by thermal erosion and aqueous dissolution of otherwise solid spatter cones. Meteoritic water and endogenous condensates act to form speleothems of complex mineralogy up to 3 m in length. We propose the new classification of “polygenetic spatter cone cave”.
