Eelgrass Distribution In The Great Bay Estuary For 2009 : Final Report, Frederick T. Short

PREP Reports & Publications

Eelgrass in the Great Bay Estuary in 2009 was once again present only in Great Bay itself and in Portsmouth Harbor. For the second year in a row, there was no eelgrass in Little Bay or in the Piscataqua River. In 2009, there was a continued loss of eelgrass biomass in Great Bay; there has been a 66.4% loss of biomass in Great Bay since 1996 and distribution is 30% less than in 1996. Although eelgrass distribution in Great Bay itself increased between 2008 and 2009, primarily due to continued expansion from natural seeding of bare areas, the Bay’s eelgrass …

Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

Knowing Your Community: Fostering Biodiversity Awareness In Our Students’ Daily Existence, Tony Cummings Bs, Academic Director

Fostering Multicultural Competence and Global Justice: an SIT Symposium

There are strong arguments suggesting that developing students’ sensitivity to local biodiversity and conservation issues is as important as emphasizing an understanding of global conservation issues happening in faraway lands (Ehrenfeld, 2009). Many students arrive at a Study Abroad destination, with a good understanding of theory, but with little field experience at home. Environmental educators in Study Abroad are able to use the novelty and grandeur of our exotic destinations to systematically teach students the patterns and processes of ecological and human communities at our sites, while inspiring a sense of place in our students. By immersing students in the …

Algal Biomass Accrual In Relation To Nutrient Availability Along A Longitudinal Gradient In The Upper Green River, Kentucky, Mary Douglas Penick

Masters Theses & Specialist Projects

Nutrient limitation in aquatic ecosystems results from a deficiency in nitrogen or phosphorus levels relative to cellular growth needs. Nutrient limitation of freshwater systems is a function of biotic and abiotic factors. Biotic factors include vascular and nonvascular plant community composition. Abiotic factors include underlying bedrock and land-use activities (e.g. agriculture, septic systems). Nutrient availability directly affects growth, productivity, and community structure of primary producers. The purpose of this study was two-fold: (1) to assess the relationship between ambient algal biomass. and in-stream nutrient levels along the longitudinal course of a river through a transition from weak to well-developed underlying …

Survey Of Resource Managers Completed On Monitoring And Management Actions For Rare Plants In Arizona And Nevada, Scott R. Abella

Public Policy and Leadership Faculty Research

In a collaborative project with Northern Arizona University and more than 35 resource managers in Arizona and Nevada, we completed a survey of monitoring and management activities that are ongoing in these states for conserving populations of rare plants. We sent questionnaires consisting of 16 questions to as many resource managers as possible in these states and had follow-up conversations with several managers willing to share their perspective on ongoing conservation actions. The findings may be interesting for managers to see what issues and management strategies other managers in the same or different regions are grappling with. Results will be …

River Sediment Sampling Methods: Causeway Building And Removal, Dillon Dittmer

Department of Environmental Studies: Undergraduate Student Theses

Abstract The Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (USFWS) suspect that causeways have a negative impact on river ecology both when installed and when removed. The Nebraska Department of Roads routinely uses causeways as a tool in the construction and repair of bridges. Although research has not been conducted on the impact of causeway building and removal data has been collected about the impact of dams, causeways, etc. on estuaries. This data is considered subjective and authors often cite sampling methods as a source of error. Currently there are no widely used handheld sampling methods that …

The Influence Of Vegetation And Landscape Position On Soil Temperature Change In A Sagebrush-Steppe Eastern Sierra Environment: Implications On Soil Taxonomy, Nathan Michael Lurie

Earth and Soil Sciences

Soil temperature is a parameter that has been studied for a considerable time and from many different perspectives. However, relatively few studies have been conducted for taxonomic purposes and fewer still have focused on how changes in soil temperature related to global climate change may affect soil taxonomy. Soil temperature regimes are used to subdivide soils with similar properties that exist in dissimilar climate zones requiring different management practices depending on intended use. Seven sites with variable surficial features were used for this study within a cohesive sagebrush-steppe Eastern Sierra glacial moraine landform. Soil temperature was measured once a month …

Stable Isotopic And Geochemical Variability Within Shallow Groundwater Beneath A Hardwood Hammock And Surface Water In An Adjoining Slough (Everglades National Park, Fl), Lee J. Florea, Dorien K. Mcgee, Jonathan G. Wynn

Earth, Environmental, and Atmospheric Sciences Faculty Publications

Data from a ten-month monitoring study during 2007 in south Florida provide insight into the variation of δ18O, δD, and δ13C of DOC in surface water and shallow groundwater of the Everglades ecosystem. Bi-monthly samples were taken from surface water and time-averaged precipitation at Taylor Slough, and shallow groundwater from a well and a small cave within Palma Vista Hammock, an exposure of the Upper Pleistocene Miami Limestone.

δ18O and δD values in shallow groundwater from the well and cave remain near the mean of -2.4 ‰ and -12 ‰, respectively (VSMOW scale). 18O and D are enriched in surface …

Measurement And Interpolation Of Sea Surface Temperature And Salinity In The Tropical Pacific: A 9,000 Nautical Mile Research Odyssey, Amber Brooks

Earth and Soil Sciences

The purpose of this project was to compare spline and inverse distance weighting interpolation tools on data collected in the tropical Pacific Ocean by ship and data from a global network of CTD floats, known as Argo floats (fig.1), to provide evidence that technological advancement and integration is aiding our understanding of the ocean-atmosphere system of planet Earth. Thirty-one sea surface temperature and salinity samples were manually taken across a 9,000 nautical mile trek of the Pacific Ocean for the months of April, May and June 2008. Argo ASCII globally gridded monthly averaged sea surface temperature and salinity data, from …

Remediation Of Soil Hydrophobicity On A Coastal Usga Sand-Based Golf Green, Troy David Thompson

Master's Theses

Managing soil hydrophobicity caused by localized dry spots (LDS) on sand based golf greens has become one of the greatest challenges for golf course superintendents and managers, especially as water restrictions intensify. The purpose of this study was to evaluate the effectiveness of thirteen soil surfactants in eliminating LDS and in maximizing root zone soil moisture on a sand based USGA golf green located on the California Central Coast. Potential water repellency of air dried cores (measured utilizing the water droplet penetration time (WDPT) method), phytotoxicity, and climate were analyzed during two experimental trials. Phytotoxicity data was collected for Trial …
