Public health hazards as a constraint on oyster production in the contiguous United States

Creator:: Rugger, Cynthia S.
Abstract:: Oyster production in the United States has declined from a leading nineteenth century fishery to a minor, failing industry. Oystermen must now depend on a diminished resource in an environment of competing and conflicting coastal uses. One of the most important influences on the industry's welfare is the sanitation of...

An analysis of the distribution of precipitation and runoff from the historical record for the continental United States

Creator:: Dolph, Jayne Ellen
Abstract:: Characterizing the distribution of precipitation at regional scales is a requirement for the development of regional scale, spatially distributed hydrologic water balance models. This study performs a preliminary assessment of the utility and limitations of historical hydro-meteorological data for providing spatially distributed precipitation estimates over large areas. The historical data...

The influence of aging dams and geography on the distribution of dam removals in the United States

Creator:: Ashley, Sara
Abstract:: Over 470 dams have been removed in the United States, and a significant increase in dam removals has occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals; as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...

Spatial patterns of anomalous runoff to precipitation ratios for watersheds within the contiguous United States arranged by level one ecoregions

Creator:: Pittman, Jason W.
Abstract:: Mean annual runoff to precipitation (R/P) ratios were generated for 966 watersheds within the contiguous United States. The watersheds were plotted using Arc View GIS and used as part of an overlay analysis with Level 1 U.S. ecoregions. The ratios were statistically evaluated to determine anomalous R/P conditions within the...

A point-data analysis of the Southern Oscillation Index (SOI) and its relationship to seasonal precipitation in the northwest United States

Creator:: Worley, Timothy J.
Abstract:: El Niflo and La Nifia are oceanographic and atmospheric phenomena that have been catalogued for well over a centuly. In El Nifio years, Peru's otherwise thy west coast is subjected to torrential rainfall. Higher ocean temperatures off the coast are deemed the culprit. Attempts to quantify this began in the...

Developing "humane" interfaces to data clearinghouses for improving the delivery of spatial information to marine resource managers

Creator:: Walsh, Kuuipo
Abstract:: Web geographic information systems (GISs) and the Internet are now providing the connectivity necessary to support large-scale data access by a wide variety of users, including not just scientific researchers, but also policy-makers and marine resource managers. However, connectivity alone cannot ensure that those who need natural resource information will...

User fees: issues and policy on Washington state public lands

Creator:: Caudill, David S.
Abstract:: Outdoor recreational activities on public lands have increased dramatically in the past few decades. Americans are logging millions of recreational visitor days (RVD's) participating in activities such as hiking, biking, wildlife viewing, photography and many others. This increased participation though is having detrimental effects on these lands and the agencies...

Change detection of land cover in a meadow landscape : the“Ranches” meadow, Silver Falls State Park, Oregon

Creator:: Anderson, Carl G.
Abstract:: From a landscape ecology perspective, meadows are often seen as landscapes in transition. Succession and change in meadows may be investigated by considering the physical and anthropogenic factors that influence the landscape through time. What is often unknown is how changes occur and how physical and anthropogenic factors contribute to...

Shake, rattle, and roll : awaking the visiting public's curiosity of geology via interpretation at Redwood National State Parks

Creator:: Natoli, Jennifer A.
Abstract:: By researching aspects of the geology of Redwood National and State Parks (RNSP) and serving for two summers as a seasonal interpretive ranger, I have developed a training manual designed for fellow rangers. The descriptive nature of the manual, combined with its vivid illustrations, is designed to enable rangers of...

Meteorological conditions associated with rain-related periglacial debris flows on Mount Hood, Oregon and Mount Rainier, Washington

Creator:: Parker, Lauren E.
Abstract:: In November of 2006 an intense rainstorm of tropical origin, known colloquially as the "Pineapple Express," inundated the Pacific Northwest region of the United States, initiating numerous periglacial debris flows on several of the stratovolcanoes in the Cascade Range of Oregon and Washington. These debris flows rapidly aggrade channels, deposit...
