This paper documents various unresolved issues in using surface temperature trends as a metric for assessing global and regional climate change. A series of examples ranging from errors caused by temperature measurements at a monitoring station to the undocumented biases in the regionally and globally averaged time series are provided. The issues are poorly understood or documented and relate to micrometeorological impacts due to warm bias in nighttime minimum temperatures, poor siting of the instrumentation, effect of winds as well as surface atmospheric water vapor content on temperature trends, the quantification of uncertainties in the homogenization of surface temperature data, …

Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Electronic Theses and Dissertations
Motivated by interest and concern over the changing coastline in Maine, this study uses the concept of sense of place to develop an understanding of how a range of users share the resource, and to explore how place meanings are associated with their social experiences and perceptions. The site for this study was the Stonington region archipelago, an area that has not yet experienced the same amount of development as seen on the southern Maine coast, yet one that has witnessed a boom in recreational use and an influx of people from other areas. Using a mixed methodology, two groups …

The Distribution And Reproductive Success Of The Western Snowy Plover Along The Oregon Coast - 2007, David J. Lauten, Kathleen J. Castelein, Raya Pruner, Marvin Friel, Eleanor P. Gaines
Institute for Natural Resources Publications
From 3 April – 21 September 2007, we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius alexandrinus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, and New River. Our objectives for the Oregon coastal population in 2007 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue selected use of mini-exclosures (MEs) to protect nests from predators …

Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. A common living shoreline design in Chesapeake Bay includes a low offshore rock sill to absorb wave energy with an emergent wetland landward of the sill to enhance erosion control, provide critical habitat, and improve water quality condition. This study is part of a larger, ongoing project to (1) evaluate erosion control effectiveness and the sustainability of offshore sill and fringing marsh design and structure, (2) evaluate ecological services (e.g., habitat value, water …

If Larvae Were Smart: A Simple Model For Optimal Settlement Behavior Of Competent Larvae, Robert J. Toonen, Andrew J. Tyre
If Larvae Were Smart: A Simple Model For Optimal Settlement Behavior Of Competent Larvae, Robert J. Toonen, Andrew J. Tyre
School of Natural Resources: Faculty Publications
Much research has been done on larval settlement cues. Rather than having simple fixed responses to constant environmental stimuli, it seems likely that settlement decisions made by individual larvae should vary depending on the individual and the conditions under which it encounters that cue. Here, we present a simple stochastic dynamic programming model that explores the conditions under which larvae may maximize their lifetime fitness by accepting lower quality habitat rather than continuing to search for superior habitat. Our model predicts that there is a relatively narrow range of parameter values over which larval selectivity among habitat types changes dramatically …

Reclamation: Managing Water In The West, A.V. Watkins Dam Safety Of Dams Modification Draft Environmental Assessment Pro-Ea-07-002, W. Russ Findlay, U.S. Department Of The Interior Bureau Of Reclamation
All U.S. Government Documents (Utah Regional Depository)
This document is an environmental assessment (EA) of the proposal to modify A.V. Watkins Dam under the Safety of Dams (SOD) Act of 1978 (Public Law 95-578, as amended). The proposed SOD modifications would correct safety deficiencies of the dam without affecting the purpose or benefits of the dam. Specifically, the embankment and foundation of the dam need to be repaired. The repairs are needed to restore the reservoir to full function and to incorporate state-of-the-art defensive measures of controlling seepage within the foundation and embankment. On November 13, 2006, emergency remedial actions were taken at A.V. Watkins Dam when …
Tourism In Lugu Hu: Helpful Or Harmful? Examining The Impact Of Tourism On Lugu Lake’S People And Environment, Joana Chan
Independent Study Project (ISP) Collection
Is tourism a boon or burden to the land and the people that it impacts? This question has plagued academics for ages. On the one hand, tourism brings not only definite economic growth for the local people, but also motivation for preservation of the local landscape. On the other hand, the arrival of tourists also ironically brings definite cultural and environmental transformations to the very people and land that visitors travel so far to see and experience.
My research examines the complexities of tourism and its impact on the environment and people of Lugu Lake, Yunnan. By surveying social and …

The Price Of Gold: The Environmental Impacts Of Toxic Chemicals In Gold Mining, Adam Goetz
The Price Of Gold: The Environmental Impacts Of Toxic Chemicals In Gold Mining, Adam Goetz
Independent Study Project (ISP) Collection
The role of mercury and cyanide in gold mining has become a hot topic in Mongolia in the past few years. In the past few months, the government has launched a crackdown on the illegal use of these chemicals in response to the contamination of Khongor soum’s drinking water which resulted from an illegal mining operation. However, there are many more sites throughout the country that are in need of cleaning as a result of the illegal use of these chemicals by small companies as well as individual miners.
This paper examines the role of a variety of different views …

Why Logging? A Value Assessment Of Forestry Uses In The Huon Forest District, Ryan Bailey
Why Logging? A Value Assessment Of Forestry Uses In The Huon Forest District, Ryan Bailey
Independent Study Project (ISP) Collection
The Huon Forest District comprises 762,800 hectares of forests in southwest Tasmania, with 128,900 hectares of that total designated as state forest managed by Forestry Tasmania. These forests are used primarily for wood production, although tourism, carbon storage, leatherwood honey and the specialty timbers industry are competing for access to these forests. This study examines the socio-economic values of these uses and determines whether the Huon Forest District is being utilized efficiently.
To accomplish this, an extensive literature review of past research was conducted. This information supplemented 7 semi-structured interviews that were conducted with experts from the forestry industry, tourism …

Reports
Harvests of American eel along the U.S. Atlantic Coast have declined in recent years, and similar patterns have been noted in the Canadian Maritime Provinces as well as in Europe with its congener, A. anguilla (Ciccotti et al., 4 1995). Fishery independent indices of abundance have also shown a decline in American eel populations in recent years (Richkus and Whalen, 1999; Geer, 2003; Montane and Fabrizio, 2006). Possible explanations for this decline include Gulf Stream shifts, pollution, overfishing, parasites, and barriers to fish passage (Castonguay et al., 1994; Haro et al., 2000). In addition, local factors such as unfavorable wind-driven …
