Reconnaissance Glacio-Chemical Studies In The Indian Himalayas, Paul Andrew Mayewski, William Berry Lyons, Nasseruddin Ahmad Jun 1981

Reconnaissance Glacio-Chemical Studies In The Indian Himalayas, Paul Andrew Mayewski, William Berry Lyons, Nasseruddin Ahmad

Earth Science Faculty Scholarship

Analysis of reactive silicate, ammonium, phosphate, iron and sodium from cores taken from three glaciers in the Kashmir portion of the Himalayas are reported as the first in a series of glacio-chemical studies designed to produce proxy paleoclimatic data for this region. This study stresses the elevation dependency of such studies and for the chemical species analyzed which are most reliable for the purpose of the study.

Acidity Of Recent Himalayan Snow, William Berry Lyons, Paul Andrew Mayewski, Nasseruddin Ahmad Jun 1981

Acidity Of Recent Himalayan Snow, William Berry Lyons, Paul Andrew Mayewski, Nasseruddin Ahmad

Earth Science Faculty Scholarship

Surface snows collected at various elevations in the Indian Himalayas were analyzed in the field for pH as part of a broader study of the chemistry. The pH values are lower than the predicted ≅5.6 for unpolluted precipitation. Analysis of NO3 + NO2, Cl, SO4 and NH4 indicate that these low pH values are not completely due to the presence of strong mineral acids. The strong correlation of pH with elevation (i.e. temperature) suggests that the low pH values are due to the snow being supersaturated with CO2.

Tidal Flexure Of Jakobshavns Glacier, West Greenland, Craig S. Lingle, Terence J. Hughes, Ronald C. Kollmeyer Jan 1981

Tidal Flexure Of Jakobshavns Glacier, West Greenland, Craig S. Lingle, Terence J. Hughes, Ronald C. Kollmeyer

Earth Science Faculty Scholarship

Jakobshavns Glacier, a floating outlet glacier on the West Greenland coast, was surveyed during July 1976. The vertical displacements of targets along two profiles perpendicular to the fjord wall bounding the north margin of the glacier were analyzed to determine the effect of flexure caused by tidal oscillations within the fjord. An analysis based on the assumption that vertical displacements of the glacier reflected pure elastic bending yielded the conclusion that the effective thickness of the ice (i.e., the thickness which remained unaffected by surface and basal cracking and which behaved as a continuum) was ∼160 m 2.6 km upglacier …

An Active Rock Glacier, Wavbal Pass, Jammu And Kashmir Himalaya, India, Paul Andrew Mayewski, P. Andrew Jeschke, N. Ahmad Jan 1981

An Active Rock Glacier, Wavbal Pass, Jammu And Kashmir Himalaya, India, Paul Andrew Mayewski, P. Andrew Jeschke, N. Ahmad

Earth Science Faculty Scholarship

A currently active rock glacier with a snout elevation of 4,055 m was observed in the Jammu and Kashmir Himalaya. Its formation is ascribed to stagnation of the terminal area of a true glacier.

Ice Mass Fluctuations In Victoria Land, Antarctica, Paul Andrew Mayewski, Jon M. Hassinger Jan 1981

Ice Mass Fluctuations In Victoria Land, Antarctica, Paul Andrew Mayewski, Jon M. Hassinger

Earth Science Faculty Scholarship

[From the introduction] During the 1980-81 field season we conducted a two-part program: the first part was spent on the Rennick Glacier in northern Victoria Land, and the second in the ice-free valleys of southern Victoria Land. The primary objective of the program was to help elucidate the glacial and climatic history of Transantarctic Mountains ice masses by interpreting the records available from the spectrum true glaciers to rock glaciers.

Dickey-Lincoln School Lakes Project Economic Analysis Study, New England Division, United States Army Engineer Division, Acres American Incorporated Jan 1981

Dickey-Lincoln School Lakes Project Economic Analysis Study, New England Division, United States Army Engineer Division, Acres American Incorporated

Dickey-Lincoln School Lakes Project

The purpose of this study was to perform an economic assessment of the Dickey-Lincoln School Lakes Project. This was accomplished by simulating the New England electrical supply system with and without the project and making a comparison of the resultant production costs.

Dickey-Lincoln School Lakes Project Environmental Impact Statement: Appendix F: Terrestrial Ecosystem Analysis (Supplement 2), University Of Maine At Orono, Maine, Cooperative Wildlife Research Unit, United States Army Engineer Division, New England Division

Dickey-Lincoln School Lakes Project

The overall study area encompassed the St. John River and its major tributaries; including the Little and Big Black Rivers (and their tributaries); and all lands extending 3.2 km (2 mi) beyond the maximum elevation of thv predicted impoundment of the Dickey Dam (1,560 km ). Research was concentra-ted in a portion of this area roughly bounded on the north by Chimenticook Stream, on the east by the St. John River, on the west by the United States-Canadian border, and on the south by a line drawn east-west through Seven Islands (Figure 1.0-1). Intensive marten studies were restricted to townships …

Dickey-Lincoln School Lakes Project At Dickey, Maine : Final Environmental Statement, Volume 1-4, U. S. Army Engineer Division, New England

Dickey-Lincoln School Lakes Project

The proposed Dickey-Lincoln School Lakes Project in northern Maine is a multipurpose installation on the St.John River. The combination hydroelectric power and flood control project is located in Aroostook County, Maine, near the Canadian border. The two proposed earth fill dams located at Dickey are 10,200 feet in length with a maximum height of 335 feet. They would impound 7.7 million acre feet of water at a maximum pool elevation 910 feet mean sea level. A second earth filled dam located 11 miles downstream at Lincoln School would serve as a regulatory dam. It would be 2100 feet in lenqth, …
