A two-layer model with an idealized continental shelf and slope bottom topography is utilized to study some properties of the response of stratified coastal regions to meteorological forcing with variations in the alongshore direction. The model is such that the coastline is straight, there are no alongshore variations in the...
The effects of alongshore variations in bottom topography and coastline on the wind-stress-forced barotropic motion over a continental shelf and slope are studied. Perturbation methods are used to obtain solutions for forced and free continental shelf waves on an idealized continental shelf and slope with small-amplitude alongshore variations in topography....
Ana1ysis of January to March samples of gaper clam larvae from Yaquina Bay, Oregon have established four hypotheses for further testing: 1) gaper clams have an approximately lunar cycle of spawning intensity with maximum production of larvae at the periods of greatest tidal amplitude, 2) the time required for development...
