Laboratory investigation of dune erosion using stereo video

Creator:: Palmsten, Margaret L. and Holman, Robert A.
Abstract:: Simple parameterizations of dune erosion are necessary for forecasting erosion potential prior to an oncoming storm. Dune erosion may be parameterized in terms of the elevation of the total water level (composed of surge, tide, and wave runup) above the dune base and period of exposure of the dune to...

Improving Acoustic Doppler Current Profiler Accuracy with Wide-Area Differential GPS and Adaptive Smoothing of Ship Velocity

Creator:: Pierce, Stephen D., Barth, John A., and Smith, Robert L.
Abstract:: Accurate ship velocity is important for determining absolute currents from acoustic Doppler current profiler (ADCP) measurements. In this paper, the authors describe the application of two methods to improve the quality of ship velocity estimates. The first uses wide-area differential global positioning system (WADGPS) navigation to improve ship positioning. During...

Dislocation modeling of blind thrusts in the eastern Los Angeles basin, California

Creator:: Myers, Daniel J., Nabelek, John L., and Yeats, Robert S.
Abstract:: The East and West Coyote Hills in the eastern Los Angeles Basin are the surface expression of uplift accompanying blind reverse faulting. Folded Quaternary strata indicate that the hills are growing and that the faults underlying them are active. Detailed subsurface mapping in the East Coyote Oil Field shows that...

Unbalanced particle flux budgets in Crater Lake, Oregon: Implications for edge effects and sediment focusing in lakes

Creator:: Dymond, Jack, Collier, Robert W., McManus, James, and Larson, Gary L.
Abstract:: Flux estimates show that upward mixing of the deep-water nitrate pool accounts for more than 85% of the total new nitrogen input to the euphotic zone of Crater Lake. Because measured primary productivity (360 mg C m-2 d-1) is 10–30 times higher than a level supported solely by the input...

Geochronology of age-progressive volcanism of the Oregon High Lava Plains : implications for the plume interpretation of Yellowstone

Creator:: Jordan, Brennan T., Grunder, Anita L., Duncan, Robert A., and Deino, Alan L.
Abstract:: The High Lava Plains province (HLP) is a late Cenozoic bimodal volcanic field at the northern margin of the Basin and Range province in southeastern Oregon that hosts a westward younging trend of silicic volcanism that crudely mirrors northeastward migration of silicic volcanism along the Yellowstone–Snake River Plain (YSRP) trend....

Spatial and temporal distribution of dissolved oxygen in Crater Lake, Oregon

Creator:: McManus, James, Collier, Robert W., Dymond, Jack, Wheat, C. Geoffrey, and Larson, Gary L.
Abstract:: Small temporal and spatial variations in the distribution of dissolved oxygen in Crater Lake, Oregon, are used to estimate the mean age of the lake’s deep water, the flux of labile organic carbon to the deep lake, and the influence of hydrothermal activity on the concentration of dissolved oxygen within...

Two coastal upwelling domains in the northern California Current system

Creator:: Huyer, Adriana, 1945-, Fleischbein, Jane, Keister, Julie Eileen, Kosro, P. Michael, 1951-, Perlin, Natalie, Smith, Robert L. (Robert Lloyd), 1935-, and Wheeler, Patricia A.
Abstract:: A pair of hydrographic sections, one north and one south of Cape Blanco at 42.9N, was sampled in five summers (1998–2000 and 2002–2003). The NH line at 44.6N lies about 130 km south of the Columbia River, and spans a relatively wide shelf off Newport, Oregon. The CR line at...

The M₂ Internal Tide off Oregon: Inferences from Data Assimilation

Creator:: Kurapov, Alexander L., Egbert, Gary D., Allen, J. S., Miller, Robert N., Erofeeva, Svetlana Y., and Kosro, P. M.
Abstract:: A linearized baroclinic, spectral-in-time tidal inverse model has been developed for assimilation of surface currents from coast-based high-frequency (HF) radars. Representer functions obtained as a part of the generalized inverse solution show that for superinertial flows information from the surface velocity measurements propagates to depth along wave characteristics, allowing internal...

Hyperspectral Imager for the Coastal Ocean: instrument description and first images

Creator:: Lucke, Robert L., Corson, Michael, McGlothlin, Norman R., Butcher, Steve D., Wood, Daniel L., Korwan, Daniel R., Li, Rong R., Snyder, William A., Davis, Curt O., and Chen, Davidson T.
Abstract:: The Hyperspectral Imager for the Coastal Ocean (HICO) is the first spaceborne hyperspectral sensor designed specifically for the coastal ocean and estuarial, riverine, or other shallow-water areas. The HICO generates hyperspectral images, primarily over the 400–900 nm spectral range, with a ground sample distance of ≈90 m (at nadir) and a high...

A comprehensive approach for habitat restoration in the Columbia Basin

Creator:: Rieman, Bruce E., Smith, Courtland L., Naiman, Robert J., Ruggerone, Gregory T., Wood, Christ C., Huntly, Nancy, Merril, Erik N., Alldredge, J. Richard, Bisson, Peter A., Congleton, James, Fausch, Kurt D., Levings, Colin, Pearcy, William, Scarnecchia, Dennis, and Smouse, Peter
Abstract:: The Columbia Basin once supported a diversity of native fishes and large runs of anadromous salmonids that sustained substantial fisheries and cultural values. Extensive land conversion, watershed disruptions, and subsequent fishery declines have led to one of the most ambitious restoration programs in the world. Progress has been made, but...
