The Toll Of Toxics: Investigating Environmental Contaminants, Donald Sparling, Barnett A. Rattner, John S. Barclay

United States Geological Survey: Staff Publications

Two recent events [the Deepwater Horizon oil spill and the Asarco settlement] bring to the fore the work of wildlife toxicologists. Focusing on amphibians, reptiles, birds, and mammals, wildlife toxicology is a component of ecotoxicology--the study of toxic effects caused by natural or synthetic pollutants on living organisms and other constituents of ecosystems (Truhaut 1977). Now a distinct discipline within the wildlife profession-practiced by members of The Wildlife Society's own Wildlife Toxicology Working Group, among others-wildlife toxicology has become increasingly important as human populations and industry have spread, causing contaminants to multiply.

Emerging Environmental Contaminants (EECs) include an array of …

Deep-Pelagic (0-3000 M) Fish Assemblage Structure Over The Mid-Atlantic Ridge Relative To The North Atlantic Subpolar Front, April B. Cook, Tracey Sutton, John K. Galbraith, M. Vecchione

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Only a tiny fraction of the world's largest volume of living space, the ocean's mid-water region, has ever been sampled. It is one of the least understood areas on earth, so as part of the International Census of Marine Life field project, MAR-ECO, a discrete-depth trawling survey was conducted in 2009 aboard the NOAA ship Henry Bigelow to examine pelagic assemblage structure and distribution over the Charlie-Gibbs Fracture Zone (CGFZ) of the northern Mid-Atlantic Ridge. The survey consisted of 11 stations divided into two transects, one northwest and one southeast of the CGFZ, which roughly coincides with the Subpolar Front. …

A Planetary-Scale Land-Sea Breeze Circulation In East Asia And The Western North Pacific, W. R. Huang, J. C-L Chan, Shih-Yu (Simon) Wang

Plants, Soils, and Climate Faculty Publications

The diurnal wind variation over the East Asian continent is commonly considered to be a combination of a land-sea breeze near the coast and a mountain–valley breeze along the slopes of the Tibetan Plateau. The local land–sea breeze along the coastline typically spansHowever, a detailed examination of the global reanalysis data suggests that this local land–sea breeze circulation apparently couples with the global-scale diurnal atmospheric pressure tide to produce a planetary-scale land–sea breeze with a spatial scale of ∼1000 km over the western North Pacific. Computations of the momentum budget and equivalent potential temperatures indicate that the atmospheric diurnal tidal …

Geodatabase Development To Support Hyperspectral Imagery Exploitation, Robert A. Fusina, John C. Fry, C Reid Nichols, Charles M. Bachmann, Rong-Rong Li, Jon Sellars, Christopher Parrish, Marcos J. Montes, Carl Gross, Stephen A. White, Krista Lee, Christopher A. Jones

Center for Coastal and Ocean Mapping

Geodatabase development for coastal studies conducted by the Naval Research Laboratory (NRL) is essential to support the exploitation of hyperspectral imagery (HSI). NRL has found that the remote sensing and mapping science community benefits from coastal classifications that group coastal types based on similar features. Selected features in project geodatabases relate to significant biological and physical forces that shape the coast. The project geodatabases help researchers understand factors that are necessary for imagery post processing, especially those features having a high degree of temporal and spatial variability. NRL project geodatabases include a hierarchy of environmental factors that extend from shallow …

Biological And Physical Analysis Of Currents And Water Masses Off The Coast Of Southeast Florida, Stephanie Healey

HCNSO Student Theses and Dissertations

Biological and physical sampling of a 10km long, east-west transect was performed during 2007, off the coast of southeast Florida. Temperature and salinity measurements were recorded using a conductivity-temperature-depth (CTD) sensor, and current direction and magnitude measurements were recorded using an acoustic Doppler current profiler (ADCP). Zooplankton samples were collected, during the daytime, using a Tucker multiple net mid-water trawl, with 760μm mesh, at intended depths of ~25m and ~200m, at three stations along the transect. Laboratory analysis indicated that several currents and water masses influenced the density distribution of calanoid copepods and chaetognaths. During April and September 2007, a …

Is New Hampshire's Climate Warming?, Lawrence C. Hamilton, Barry D. Keim, Cameron P. Wake

Carsey Publications

This Carsey brief looks at temperature anomalies across New Hampshire and shows that not only is the state warmer than it has been in the past, but it is also warming faster than much of the planet. Sociologist Lawrence Hamilton, research associate professor Cameron Wake, and former NH state climatologist Barry Keim analyzed over 100 years of temperatures across the state to produce this data for the Carsey Institute in August 2010.

Assessing The Short-Term Forecast Capability Of Nonstandardized Surface Observations Using The National Digital Forecast Database (Ndfd), Joby Hilliker, G Akasapu, G S. Young

Earth & Space Sciences Faculty Publications

The number of surface observations from nonstandardized networks across the United States has appreciably increased the last several years. Automated Weather Services, Inc. (AWS), maintains one example of this type of network offering nonstandardized observations for similar to 8000 sites. The present study assesses the utility of such a network to improve short-term (i.e., lead times < 12 h) National Digital Forecast Database (NDFD) forecasts for three parameters most relevant to the energy industry-temperature, dewpoint, and wind speed. A 1-yr sample of 13 AWS sites is chosen to evaluate the magnitude of forecast improvement (skill) and influence of physical location (siting) on such improvements. Hourly predictions are generated using generalized additive modeling (GAM)-a nonlinear statistical equation incorporating a predetermined set of the most significant AWS and NDFD predictors. Two references are used for comparison: (i) persistence climatology (PC) forecasts and (ii) NDFD forecasts calibrated to the AWS sites (CNDFD). The skill, measured via the percent improvement (reduction) in the mean absolute error (MAE), of forecasts generated by the study's technique (CNDFD+) is comparable (< 5%) to PC for lead times of 1-3 h for dewpoint and wind speed. Skill relative to PC slowly increases with lead time, with temperature exhibiting the greatest relative-to-PC skill (similar to 30% at 12 h). When compared to baseline CNDFD forecasts, the MAE of the generated CNDFD+ forecasts is reduced 65% for temperature and dewpoint at the 1-h lead time. An exponential drop in improvement occurs for longer lead times. Wind speed improvements are notably less, with little skill (< 5%) demonstrated for forecasts beyond 4 h. Overall, CNDFD+ forecasts have the greatest accuracy relative to CNDFD and PC for the middle (3-7 h) lead times tested in the study. Variations in CNDFD+ skill exist with respect to AWS location. Tested stations located in complex terrain generally exhibit greater skill relative to CNDFD than the 13-station average for temperature (and, to a lesser degree, dewpoint). Relative to PC, however, the same subset of stations exhibits skill below the 13-station average. No conclusive relationship can be made between CNDFD+ skill and the sample stations located near water.

Non-­Native Invasive Aquatic Plant And Mussel Survey Of Six Umpqua National Forest Area Lakes, Mark Sytsma, Rich Miller, Rupa Shrestha

Center for Lakes and Reservoirs Publications and Presentations

Six lakes and ponds located within or near the Umpqua National Forest were surveyed for non-­native aquatic plants and mussels during August, 2009. A diverse assemblage of native plants was identified along with one possible non-­native aquatic plant hybrid in Herberts Pond. The possible hybrid between the non-­native species Myriophyllum spicatum and the native species M. sibiricum requires genetic analysis for identification. Water chemistry is suitable for the establishment of invasive mussels in Buckeye Lake; however, no zebra or quagga mussel veligers were detected in any of the lakes.

Oxygen Isotopes As A Tracer Of Dom Processes In River-Estuary Systems, Joy Ashley Matthews

OES Theses and Dissertations

In the biogeochemical study of dissolved organic matter (DOM) in natural waters, stable isotopes are used to provide insight into both the sources of DOM and the processes affecting its alteration. Through the research presented here, oxygen isotopes are incorporated into the study of DOM through the adaptation of a pyrolysis elemental analysis isotope ratio mass spectrometer method, and sample preparation using two-stage ultrafiltration.

The application of oxygen isotopes to the study of DOM is demonstrated in two studies. First, natural abundance of δ¹⁸O in DOM is explored in the Delaware estuary. Using a two end-member mixing model, …

A Differential Absorption Model For Remote Sensing Of Atmospheric Pressure, Shivam J. Shah

Electrical & Computer Engineering Theses & Dissertations

The goal of the project is to develop and test a "model based" radar processing strategy that is compatible with the concept of a "cognitive radar". The basic approach will be to develop a cognitive radar algorithm (genetic algorithm) based on the capabilities of an existing commercially available Software Radio. While the focus of this effort is the development of a candidate approach for genetic algorithm, the longer term goal would be to implement the approach using this software radio technology to provide a low cost radar processor. The proposed technology would use differential absorption radar working at the 50-56 …
