Development of 2D models to estimate nearshore bathymetry and sediment transport

Creator:: Splinter, Kristen D.
Abstract:: We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The ﬁrst two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

Determination of food carbon assimilation in copepods

Creator:: O'Connors, Harold Blane Jr
Abstract:: A method for measuring food carbon assimilation in the copepod Calanus finmarchicus was developed, using the diatom Ditylum brightwelli as food. The amount of particulate food carbon ingested was determined as the difference between CHN analyzer analyses for particulate food carbon of pre- and post-grazed food suspensions. The fraction of...

Density currents induced by freezing in a shallow polar ocean : some heuristic models

Creator:: Badan-Dangon, Antoine Renaud Fabrice
Abstract:: An ice cover which progrades over a shallow ocean in the form of an ice front may induce a baroclinic flow in the underlying water, provided that the brine excluded from the freezing surface layer is mixed rapidly through out the underlying water column. A series of models are developed...

Calcium analysis in seawater by an ion sensitive electrode

Creator:: Bradford, Wesley L.
Abstract:: A newly developed calcium sensitive liquid-liquid membrane electrode is used to analyse seawater off the Oregon coast in waters fed by the Columbia River runoff. For the analysis, an application of the method of standard additions is used requiring the assumption that the seawater is of so high a salt...

Field validation of a nearshore circulation model for alongshore-nonuniform flows

Creator:: Wilson, Gregory W.
Abstract:: We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...

Dispersion of the Columbia River plume based on radioactivity measurements

Creator:: Frederick, Lawrence Churchill
Abstract:: An investigation has been made of several physical parameters of the effluent plume of the Columbia River as it enters the Pacific Ocean. Radioactive material in trace amounts enters the Columbia River from the Hanford nuclear reactors at Richland, Washington. One of these nuclides, chromium -51, has been used to...

The activity pattern of Diadora aspera

Creator:: Boese, Bruce Leon
Abstract:: Diadora aspera is an intertidal keyhole limpet found in the mid-tidal zone. Its activity pattern was estimated under laboratory conditions using time-lapse-photography and manometric determinations of oxygen consumption. Statistical and computer analyses of the photographic data suggest the presence of both a 24 hour and a 12-13 hour rhythm in...
