Contribution of cold seep barite to the barium geochemical budget of a marginal basin

Creator:: McQuay, Erica L.
Abstract:: Large barite (BaSO4) structures mark cold seeps in the southern San Clemente Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes measured in surrounding California Borderland basins. Analyses of sediment trap material, water column samples, sediments and pore water indicate that expected bariumbearing mineral...

Permanent Moorages and Temporary Tie-Up Facilities in the Portland/Vancouver Metropolitan Area: Meeting the Needs of the Larger Recreational Boat

Creator:: McManus, John F.
Abstract:: This study is composed of two parts. Section I deals with developed moorages and marinas--where they are; what services are offered in each, and how well the existing supply of permanent moorages serves the boating public. Section II examines the need for temporary 'harbors of refuge' in the area, what...

Mapping, geochemical sampling and submersible observations of recent activity on the San Clemente fault zone : 27 March to 4 April 2000

Creator:: McManus, James, Goldfinger, Chris, and Torres, Marta E.
Abstract:: The investigation described in this project will test the hypothesis that fluxes of carbon, barium, manganese, iron and uranium associated with fluid seepage at the San Clemente fracture zone significantly affect the geochemical budgets for these elements, and ultimately result in anomalously high benthic fluxes throughout the San Clemente basin.

Geochemical cycling in a Pacific Northwest estuary (Tillamook Bay, Oregon, USA)

Creator:: Colbert, Debbie L.
Abstract:: This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...

Geochemical observations on Hydrate Ridge, Cascadia Margin : July 1999

Creator:: Torres, Marta E., Bohrmann, Gerhard, Brown, Kevin, deAngelis, Marie, Hammond, Douglas, Klinkhammer, Gary, McManus, James, Suess, Erwin, and Trehu, Anne
Abstract:: Geophysical and biogeochemical processes associated with fluid venting from active and passive continental margins will receive significant scientific and economic attention into the next century and are of major societal relevance. An important unknown among these interrelated processes is the role played by methane gas hydrates, at and below the...

Geochemical observations on Hydrate Ridge, Cascadia Margin during R/V BROWN-ROPOS cruise : August 1998

Creator:: Torres, Marta E., Brown, Kevin, Collier, Robert W., deAngelis, Marie, Hammond, Douglas, McManus, James, Rehder, Gregor, and Trehu, Anne
Abstract:: A massive release of methane on the Cascadia Hydrate Ridge was documented during a ROPOS program in August 1998, consistent with previously reported observations in 1996. An extensive survey of the seafloor revealed that the seeps lie within a narrow band trending 109 degrees. This feature parallels larger mounds imaged...

Great white mystery : learning from aquarium exhibits

Creator:: Wharton, James M.
Abstract:: In the summer of 2001 the Oregon Coast Aquarium opened a new exhibit on sharks entitled, "Great White Mystery: What Happened to Surfer Bob?" For the purposes of this study, a survey was designed to determine whether visitors to the new exhibit learned factual information or left with changed attitudes...

Oregon's Columbia River ports (excluding Portland) : a survey of operations, facilities, finances, and plans

Creator:: Oyala, James W. and Oregon State University. Marine Advisory Program
Abstract:: Oregon's Columbia River ports are as diversified as the lands on which they are located. From Astoria to Umatilla, the common factor that links the ports is the Columbia River, which borders all of the ports discussed in this publication.

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...
