Though the majority of the Antarctic continent is covered by ice, portions of Antarctica, mainly in the McMurdo Dry Valleys and the Transantarctic Mountains (TAM), are currently ice-free. The soils which have developed on these surfaces have been re-worked by the advance and ret…

This project examines the role of plant diversity in the resilience and vulnerability of socioecological systems using an archaeological case study of the ancient Maya of the Mopan River valley, Belize. Archaeologists have documented major sociopolitical transformations in this …
Tunnels are classified as complex engineering structures, which requires careful analysis and design procedures. Any instability of tunnels will be highly detrimental to their performance thereby posing a threat to public safety, consequently cause life-threatening and infrastru…
Central Florida’s Ocala National Forest is the largest remnant of the unique-to-the-region Sand Pine Scrub ecosystem. This ecosystem exhibits a surprising wealth of biodiversity despite what may be characterized as barren, difficult, dry, pyrogenic conditions. Significant prehis…
This study was made of classifying the soils and determining the heavy metal pollution of the soils and water resources in the Bursa province. Twelve profiles of five different soil type were examined and classified according to the systems of Fitzpatrick (1988), FAO/UNESCO (197…
Many chemical and physical factors govern the mobility of metal contaminants in soils and clay systems; some of these chemical factors include mineralogical composition, cation exchange capacity, organic matter content, pH and the ionic strength of soil water. This makes underst…
Investigation has been made into the properties of Red Soilsin West Java, Indonesia, selected from two different parent materials.Profiles P. Tb and P. Rb are derived from dacitic tuff and P. Js frompumice volcanic ash, both of which are acid in character. ProfilesL. Km, L. Dr a…
During modern times of unprecedented climate change, historical and geological records of past climate allow us to understand and project ancient patterns in the carbon and water cycle. Plants and soils are excellent records for climate because of the direct interaction between …
This thesis presents results of centrifuge model tests and three-dimensional large deformation finite element (LDFE) analysis on axial pipe-soil sliding behaviour of partially embedded subsea pipelines. 3D re-meshing and interpolation technique with small strain (RITSS) approach…
In recent years, scientists have become increasingly concerned about microplastic pollution. Efforts to raise awareness about microplastic pollution were initiated by marine and aquatic scientists who saw increasing amounts of plastic polluting surface water. However, recently s…
An automated method for the simultaneous measurement of water content, soil water pressure, and soil bulk electrical conductivity in soil columns was developed based on time domain reflectometry (TDR), three wire probes and pressure transducers. Soil electrical conductivity was …
The use of biosolids as a soil fertilizer has been shown to be an agronomically beneficial practice. Biosolids supply nutrients and organic matter to semi-arid soils. However, biosolids contain heavy metals. Long-term use may result in the accumulation of heavy metals in soils. …
Experiments have been conducted on measuring the combined effects of (1) time after sludge application, (2) temperature of equilibration, and (3) soil properties (principally pH and texture) on P availability and chemical fractions. Plant-available P (measured by iron-oxide stri…
Hydrophobic regions in sandy soils have been reported for citrus groves, rangelands, and golf course putting greens. Previous studies have implicated either lipids or organic acids as the causal agent for soil hydrophobicity. The present study was conducted to provide a more com…
