The development and application of benthic classifications for coral reef ecosystems below 30 m depth using multibeam bathymetry : Tutuila, American Samoa

Creator:: Lundblad, Emily Ruth
Abstract:: Coral reef ecosystems are the most diverse on earth, and their subsistence is being threatened by natural and adverse anthropogenic patterns and processes. In an effort to understand and protect these marine environments, several programs have outlined strategies and initiatives. For example, the United States Coral Reef Task Force’s Mapping...

Integration of submersible transect data andhigh-resolution sonar imagery for a habitat-based groundfish assessment of Heceta Bank, Oregon

Creator:: Nasby, Nicole M.
Abstract:: Dramatic declines in several groundfish populations have occurred along the U.S. West Coast during the last decade (PFMC 1999, Sampson 1997, Ralston 1998, Bloeser 1999). One problem exacerbating these declines is insufficient stock assessments, especially for species of west coast rockfish (Family Scorpaenidae, Genus Sebastes) which comprise the core of...

Assessment of the potential for conflict between existing ocean space use and renewable energy development off the coast of Oregon

Creator:: Sullivan, Colleen M.
Abstract:: Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...

GIS modeling of potential marine protected areas in the Northwest Atlantic via biological and socioeconomic parameters

Creator:: Keith, Charles M.
Abstract:: Overfishing of our national marine resources has degraded some of the most productive fishing regions in the Northwest Atlantic Ocean, most notably the Gulf of Maine and Georges Bank. These regions may have shifted from productive trophic regimes to a less than optimal state therefore reducing fishers’ catches and associated...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

Derivation of near-shore bathymetry from multispectral satellite imagery used in a coastal terrain model for the topographic analysis of human influence on coral reefs

Creator:: Hogrefe, Kyle Richard
Abstract:: The analysis of material and energy exchange between the marine and terrestrial components of island ecosystems enables research into the impact of human population and land use on the health of coral reef habitat. Satellite and acoustic remote sensing technologies enable the collection of data to produce high resolution bathymetry...

Spatial Variability Mapping of pH in Oregon Organic Farms using Geographic Information Systems (GIS) Geospatial Interpolation Models

Creator:: Stewart, Julie A.
Abstract:: This internship project (Dr. Dawn Wright—Department of Geoscience) was a synthesis of several aspects of the research process. The documentation of methods consisted of: primary data collection of soil samples, geographical coordinates, georeferencing, basemap creation, laboratory machine operation, laboratory methods, laboratory quality control planning, statistical analysis, and geo-statistical analysis using...

Biogeography of nonindigenous species: from description to prediction

Creator:: Reusser, Deborah A.
Abstract:: Nonindigenous species are a major threat to the ecological integrity and biodiversity of marine and estuarine ecosystems. To become a successful invader, species must pass through four phases: (1) survive transport, (2) survive release, (3) establish a population, and (4) expand their range. To better understand these processes, an integrated...

The Potential of Dynamic Segmentation for Aquatic Ecosystem Management : Pacific Lamprey Decline in the Native Lands of the Confederated Tribes of Siletz Indians (Oregon, USA)

Creator:: Palacios, Kelly C.
Abstract:: The Lamprey Eel Decline project conducted by the Confederated Tribes of Siletz Indians (CTSI) combined traditional ecological knowledge, scientific research and geographic information science. CTSI wanted to learn why the Pacific lamprey (Lampetra tridentata), a culturally and ecologically important species, was declining in the streams within their native land area....

Spatial interpolation in other dimensions

Creator:: Martin, Peter
Abstract:: The purpose of this work is to broaden the theoretical foundations of interpolation of spatial data, by showing how ideas and methods from information theory and signal processing are applicable to the the work of geographers. Attention is drawn to the distinction between what we study and how we represent...
