Evolution Of Sprague Neck Bar, Machias Bay, Maine, Rebecca A. Nestor Dec 2001

Evolution Of Sprague Neck Bar, Machias Bay, Maine, Rebecca A. Nestor

Electronic Theses and Dissertations

Sprague Neck Bar is a recurved barrier spit located in Machias Bay, Maine. Principle geomorphic features associated with Sprague Neck Bar include bedrock, coastal bluffs, till in grounding line (the Pond Ridge Moraine) and washboard moraines, mudflats, sand and gravel beaches, and a salt marsh. Sprague Neck Bar is attached to the western end of the Pond Ridge Moraine (Sprague Neck) and extends northward toward the head of Machias Bay for 845 meters before the system recurves to the southeast for 232 meters. The recurve system forms a broad tidal flat with evidence for northward and eastward migration of the …

Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson Oct 2001

Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson

Conservation and Survey Division

A data base collected over the last 100 years, containing both surface and subsurface information, has allowed us to begin to understand the physical framework of Nebraska. We have learned that even in the stable Midcontinent region of North America, there has been an active geologic history. This framework has been deciphered by our programs of surface geologic mapping and by the study of rock samples from both water wells and those deeper test wells for oil and gas. Determining the major structural features across the state (figure 1) has allowed us to better understand both the occurrences of its …

An Environmental Geochemical Study Of Connecticut Marsh Sediments, Nicole A. Heller, Michael A. Kruge, Johan C. Varekamp, Tabitha Zierzow Mar 2001

An Environmental Geochemical Study Of Connecticut Marsh Sediments, Nicole A. Heller, Michael A. Kruge, Johan C. Varekamp, Tabitha Zierzow

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Core material from Spartina-dominated Housatonic and Connecticut River estuarine sites (ranging from low to high marsh) were investigated in order to test the hypothesis that organic and inorganic pollutants preferentially accumulate in the low marsh environment. Radiometric data indicate that the low marsh setting experienced sedimentation rates an order of magnitude greater than that of the mid to high marsh. The low marsh sediments from the Housatonic tend to have significantly higher concentrations of trace metals (e.g., Cu and Zn, likely contributed by brass mills formerly active upstream). Petrographic examination of the samples under reflected white and blue light …

Spatial Distribution Of Phosphorus In Fluvial Sediments From The James River Basin, Sw Missouri, Briain Fredrick Jan 2001

Spatial Distribution Of Phosphorus In Fluvial Sediments From The James River Basin, Sw Missouri, Briain Fredrick

MSU Graduate Theses

Degraded ·water quality in the James River Arm of Table Rock Lake, southwest Missouri has raised concerns about sources and transport of nutrients, especially phosphorus, in the James River Basin. Sections of the James River Basin have been identified as having excessive nutrient problems on the Missouri Department of Natural Resources 303d list and ranked fifth in the state for water quality improvements. Understanding the sources and transport patterns of phosphorus in the James River is necessary to evaluate contamination problems and the effectiveness of management efforts to reduce phosphorus inputs to the lake. This study uses bed sediments to …

Spatial Assessment Of Nonpoint Phosphorus Sources Using Streambed Sediment Monitoring In The Kings River Basin, Nw Arkansas, Jason W. White Jan 2001

Spatial Assessment Of Nonpoint Phosphorus Sources Using Streambed Sediment Monitoring In The Kings River Basin, Nw Arkansas, Jason W. White

MSU Graduate Theses

This study of the Kings River Basin provides a watershed-scale assessment of streambed sediment-Phosphorus (P) and its sources on the landscape. The Kings River drains into Table Rock Lake where surface algal blooms have concerned water scientists and disrupted summer tourism. There are questions about how sediment loads, widespread poultry and cattle operations, and sewage treatment plants are affecting water quality. Previous water quality studies across the U.S. have generally evaluated watercolurnn P. In contrast, few studies have used streambed sediment monitoring to detect P levels at a watershed-scale, and none have been attempted in the Kings River Basin. Sediment …

Spatial Patterns And Floodplain Contributions Of Mining-Related Contaminants In Chat Creek Watershed, Southwest Missouri, Jimmy Trimble Jan 2001

Spatial Patterns And Floodplain Contributions Of Mining-Related Contaminants In Chat Creek Watershed, Southwest Missouri, Jimmy Trimble

MSU Graduate Theses

Past mining activities have left a legacy of water quality problems in the Tri-State Mining District. Contemporary environmental risks stem from the release of lead and zinc from mine tailings previously dispersed far downstream in alluvial deposits as well as abandoned tailings piles. This study examines mining-related heavy metal contamination in the Chat Creek Watershed. Chat Creek drains the area near Aurora, Missouri on the eastern edge of the Tri-State District where mining occurred from 1886 to about 1930. This study identifies the spatial distribution of metal contamination in fluvial sediments and quantifies the role of bank erosion as a …
