Structure-forming benthic invertebrates : habitat distributions on the continental margin of Oregon and Washington

Creator:: Strom, Natalie A.
Abstract:: Structure-forming invertebrates belong to a polyphyletic group of primarily sessile and sedentary megafauna that can significantly enhance the complexity of physical habitats. A number of these organisms, including cold-water corals and sponges, are known to be slow growing and vulnerable to physical disturbance. In addition, as filter feeders, these invertebrates...

Movement and abundance of lingcod (Ophiodon elongatus) in Yaquina Bay Estuary, Oregon: evidence for essential habitat designation

Creator:: Schwager, Tad W.
Abstract:: Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...

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...

Identifying habitat factors for canary rockfish (Sebastes pinniger) off Washington and Oregon using environmental data and trawl logbooks

Creator:: Vestfals, Cathleen D.
Abstract:: If fisheries managers are to effectively manage commercially exploited fish populations, a basic understanding of the factors that influence fish distribution and abundance is required. In 2005, efforts to identify Essential Fish Habitat (EFH) for the 82 groundfish species managed by the Pacific Fishery Management Council along the West Coast...

Video on the rocks : use of a video lander platform as a survey tool for a high-relief nearshore temperate rocky reef

Creator:: Easton, Ryan Reid
Abstract:: The nearshore waters off the Oregon coast (< 73 meters) are a region of high productivity and economic value, with a variety of habitats that include rock outcrops. Temperate reef habitats are important to many commercially important fishes inhabiting the Pacific coast, including canary rockfish (Sebastes pinniger) and yelloweye rockfish...

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...

A Bayesian approach to habitat suitability prediction

Creator:: Lockett, Daniel Edwin, IV
Abstract:: For the west coast of North America, from northern California to southern Washington, a habitat suitability prediction framework was developed to support wave energy device siting. Concern that wave energy devices may impact the seafloor and benthos has renewed research interest in the distribution of marine benthic invertebrates and factors...

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...

Evaluating Coastal Protection Services Associated with Restoration Management of an Endangered Shorebird in Oregon, U.S.A.

Creator:: Carroll, Lindsay J.
Abstract:: Coastal sand dunes and beaches offer a variety of ecosystem services such as coastal protection, sand stabilization, species conservation, and recreation. However, the management and balance of ecosystem services offered by dunes and beaches is challenging when ecosystem services interact across the landscape. Management focusing only on one ecosystem service...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...
