Baltimore Harbor And Channels Aquatic Benthos Investigations : Final Technical Report, Robert J. Diaz, Linda C. Schaffner, Robert J. Byrne, Robert A. Gammisch

Reports

This report describes work performed by the Virginia Institute of Marine Science, School of Marine Science of the College of William and Mary, Gloucester Point, VA, to document the existing preoperational conditions at four locations in the Chesapeake Bay selected as possible dredged material disposal areas for the deepening of the Baltimore Channel. The work was sponsored by the Baltimore District Corps of Engineers.

The objectives of this work were at each of the four potential disposal sites:

1 -document the surface (0-15 em) sediment conditions spatially and temporally

2 - document macrobenthic communities spatially and temporally.

3 - empty …


Physical Properties Of Tar Sand Tailings That Influence Their Ability To Sustain Plant Growth, Timothy Cole Jul 1985

Physical Properties Of Tar Sand Tailings That Influence Their Ability To Sustain Plant Growth, Timothy Cole

Masters Theses & Specialist Projects

The mining of bituminous sandstone rock for the purpose of extracting bitumen has created a need for reclamation. One such mine is located in northern Logan County. Their mining operation involves removing large sections of sandstone, which is impregnated with bitumen, and crushing it to sand-sized material. The sand-sized material is then mixed with organic solvents which extract the bitumen. Once separated, the bitumen is stored for future refinement and the spent sand is stockpiled for later disposal.

The spent sands or waste material are referred to as tar sand tailings. These tailings have particular properties which make reclamation efforts …


Communication Networks And The Adoption Of Three Farn Practices, P. W. Fry, F. K. Goss May 1985

Communication Networks And The Adoption Of Three Farn Practices, P. W. Fry, F. K. Goss

All other publications

The report commences with a discussion of the diffusion and adoption model, and illustrates some of the research observations and practical outcomes that have emerged in recent years, An overview of social network research is presented as a means of understanding communication exchanges and providing data relevant to the diffusion debate. The communication and adoption studies are then reported in three separate sections in the order they were conducted. (A map of the location of the survey areas is shown in Figure I ) . The objectives, survey method, results and a summary are presented for each study.

Classification, Paleoecology, And Biostratigraphy Of Crinoids From The Stull Shale (Late Pennsylvanian) Of Nebraska, Kansas, And Iowa, Roger K. Pabian, Harrell L. Strimple Mar 1985

Classification, Paleoecology, And Biostratigraphy Of Crinoids From The Stull Shale (Late Pennsylvanian) Of Nebraska, Kansas, And Iowa, Roger K. Pabian, Harrell L. Strimple

Bulletin of the University of Nebraska State Museum

Thirteen species of crinoids representing the families Diphuicrinidae, catacrinidae, Pirasocrinidae, Erisocrinidae, Cromyocrinidae, Cymbiocrinidae, Scytalocrinidae, and Ampelocrinidae have been collected from the Stull Shale Member of the Kanwaka Formation in the Shawnee Group of the Virgil Series (Upper Pennsylvanian) from near Weeping Water and Plattsmouth, Nebraska, and near Pacific Junction, Iowa. Exposures of the Stull Shale near Melvern, Kansas, have yielded 14 species of crinoids representing the families Diphuicrinidae, Catacrinidae, Pirasocrinidae, Lophocrinidae Allagecrinidae, Cymbiocrinidae, Erisocrinidae, Apographiocrinidae, and Stellarocrinidae. All but two of the species present in the Stull Shale have been previously reported from other stratigraphic horizons, including the Vinland Shale …

The Quaternary Bone Caves And Associated Sites At Wallingford, Jamaica, Donald A. Mcfarlane, R. E. Gledhill

WM Keck Science Faculty Papers

A group of caves associated with the sink of the One Eye River in St. Elizabeth Parish, Jamaica, have been the subject of numerous important palaeontological investigations beginning 1919. Unfortunately, considerable confusion has arisen in the literature through inadequate documentation of different sites. The caves of the immediate area are described and located, and their palaeontological significance is summarised in the light of recent taxonomic review and relevant geochronological evidence.
