A comparison of seafloor sonar classification methods through the use of error matrices and 3 dimensional GIS visualization : a multibeam sonar investigation of Nehalem Bank, Oregon

Creator:: Lanier, Andrew S.
Abstract:: Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Kongsberg Simrad EM-300 operating at 30 kHz. The data set collected includes both topographic...

Benefits of Geographic Information Systems for State and Regional Ocean Management

Creator:: Sowers, Derek C.
Abstract:: The current and potential benefits of using geographic information systems (GIS) to support state-level and regional-scale ocean management in the United States are evaluated. Specifically, the role of GIS in facilitating improved integration of management strategies for a variety of resource use issues across multiple management jurisdictions is examined, along...

A satellite-derived climatology of global ocean winds

Creator:: Risien, Craig Miller
Abstract:: A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...

Mapping surficial geologic habitats of the Oregon continental margin using integrated interpretive GIS techniques

Creator:: Romsos, Christopher G.
Abstract:: We map the regional physiography and surficial lithology (Surficial Geologic Habitat or SGH) over the continental margin of Oregon. This thesis develops, describes, and implements an iterative interpretive method to map seafloor habitat types from disparate geological and geophysical datasets including: bathymetric images, sidescan sonar images, seismic reflection profiles, sediment...

Using remote sensing, in situ observations, and geographic information systems to map benthic habitats at Heceta Bank, Oregon

Creator:: Whitmire, Curt E.
Abstract:: Dramatic declines in many species of demersal fishes off the West Coast have resulted in the designation of nine commercially important species as being overfished. While the causes of those declines are not clearly understood, the fact remains that a paucity of life history and abundance data exists for many...

Where's the ground surface? Elevation bias in LIDAR-derived digital elevation models due to dense vegetation in Oregon tidal marshes

Creator:: Ewald, Michael J.
Abstract:: Light Detection and Ranging (LIDAR) is a powerful resource for coastal and wetland managers and its use is increasing. Vegetation density and other land cover characteristics influence the accuracy of LIDAR-derived ground surface digital elevation models; however, the degree to which wetland land cover biases LIDAR estimates of the ground...

A geographic information system and remote sensing to support community-based coastal hazards planning in the Netarts Littoral Cell, Oregon

Creator:: Revell, David
Abstract:: The 14-km long Netarts Littoral Cell, located on the northern Oregon coast, experienced episodic erosion as a result of the severe 1997-98 El Nino and 1998-99 La Nina. The erosion events led to the development of a unique partnership bridging scientists, stakeholders, and various planning agencies. To address these erosion...

Habitat mapping and identifying suitable habitat of Redfish Rocks Pilot Marine Reserve, Port Orford, Oregon

Creator:: Amolo, Rizaller C.
Abstract:: Establishment of marine protected areas (MPAs) has been documented to effectively manage marine resource's diversity and enhance fisheries productivity. However, there must be a critical consideration of how these sites are selected and the actual description of the site itself. Its effectiveness is greatly dependent on understanding these habitats and...

Development of benthic habitat maps and GIS (Geographic Information System) modelling to support coastal zone management in Phu Quoc, Vietnam

Creator:: Nguyen, Vinh X.
Abstract:: Situated off the west coast of Vietnam in the Gulf of Thailand, Phu Quoc archipelago and its waters are well-known for their rich natural resources, especially the bounty of fishery resources. Under increasing pressure from the growing population, fishing, and tourism development, there is a strong need to formulate an...

Tillamook Bay national estuary project watershed information system

Creator:: Busse, Katherine M.
Abstract:: This report is organized into four chapters that provide background on watershed topics, GIS applications, and methodology related to development of the TBNEP Watershed Information System. The need for this product is established in Chapter two. First, the role of ecosystem management and the Tillamook Bay watershed is presented before...
