Mechanical And Chemical Weathering Of Periglacial And Non-Periglacial Forms On The Eastern Fosheim Peninsula, Ellesmere Island (Northwest Territories), Cameron Lawrence Chadwick Jan 1996

Mechanical And Chemical Weathering Of Periglacial And Non-Periglacial Forms On The Eastern Fosheim Peninsula, Ellesmere Island (Northwest Territories), Cameron Lawrence Chadwick

Theses and Dissertations (Comprehensive)

The purpose of this study is to examine the differences in the mechanical and chemical weathering of different periglacial and non-periglacial forms on the eastern Fosheim Peninsula. Forms studied include: solifluction lobes, non-sorted stripes, polygons, mudboils, wetted sloped, dry ridge and wet meadow. Most sites including the periglacial forms of solifluction lobes, non-sorted stripes, and polygons show signs of chemical and mechanical weathering. The weathering found at all sites was minute but may be significant given the slow rates of weathering in this environment. The individual environmental variables of moisture and temperature levels do not appear to have a direct …


Constraints On Present-Day Basin And Range Deformation From Space Geodesy, Jeffrey Lee, Timothy H. Dixon, Stefano Robaudo, Marith C. Reheis Aug 1995

Constraints On Present-Day Basin And Range Deformation From Space Geodesy, Jeffrey Lee, Timothy H. Dixon, Stefano Robaudo, Marith C. Reheis

All Faculty Scholarship for the College of the Sciences

We use new space geodetic data from very long baseline interferometry and satellite laser ranging combined with other geodetic and geologic data to study contemporary deformation in the Basin and Range province of the western United States. Northwest motion of the central Sierra Nevada block relative to stable North America, a measure of integrated Basin and Range deformation, is 12.1±1.2 mm/yr oriented N38°W±5° (one standard error), in agreement with previous geological estimates within uncertainties. This velocity reflects both east-west extension concentrated in the eastern Basin and Range and north-northwest directed right lateral shear concentrated in the western Basin and Range. …

Evaluation Of Lake Fertilization As A Tool To Assist In The Recovery Of The Snake River Sockeye Salmon (Oncorhynchus Nerka), Howard P. Gross May 1995

Evaluation Of Lake Fertilization As A Tool To Assist In The Recovery Of The Snake River Sockeye Salmon (Oncorhynchus Nerka), Howard P. Gross

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I analyzed lake fertilization (with nitrogen and phosphorus) as a tool to assist in the recovery of the Snake River sockeye salmon (Oncorhynchus nerka) in the oligotrophic Sawtooth Valley Lakes in southcentral Idaho. These analyses involved monitoring, manipulating, and modelling several aspects of the lakes' primary producer, nutrient, and light parameters.

In Pettit Lake, I evaluated the effects of metalimnetic and epilimnetic fertilization in 330-m3 mesocosms. The metalimnetic treatment was equal to or more effective than the epilimnetic treatment in increasing chlorophyll a, phytoplankton biovolume, and primary productivity, yet caused smaller changes in periphyton growth and …


Geology Of The Ogallala/High Plains Regional Aquifer System In Nebraska: Field Trip No. 6, Robert F. Diffendal Jr. Apr 1995

Geology Of The Ogallala/High Plains Regional Aquifer System In Nebraska: Field Trip No. 6, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

This guide is mostly figures with a reference section containing some of the pertinent literature on the Cenozoic geology we will see over the next four days. We will make all 17 stops if the weather is reasonably good and the roads are passable. On the first day, April 29, we will try to get to stops 1–5, the more distal parts of the Ogallala and younger deposits in Nebraska. On April 30, we will try to visit stops 6–9. Stops 10–15, in areas closer to the sediment sources of the Ogallala and some of the younger units, will be …


Book Review: Quaternary Geology And Geomorphology Of South America By C. Clapperton, William J. Wayne Mar 1995

Book Review: Quaternary Geology And Geomorphology Of South America By C. Clapperton, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Dr. Clapperton is to be commended for having taken on the monumental task of a review of the present state of knowledge of the Quaternary of the entire continent of South America. Quaternary Geology and Geomorphology of South America is a massive, interestingly written, but expensive volume that covers exactly what its title suggests. In spite of the paucity of information on many aspects of the Quaternary geology of this continent, which extends from north of the equator nearly to the Antarctic, the author has succeeded in reviewing and synthesizing most of the material that does exist. To do so …
