The importance of leads, sea ice motion, and frazil ice on the wintertime ocean
Boundary layer was examined by using a large-eddy simulation turbulence model coupled to a
thermodynamic slab ice model. Coupling was achieved through exchange coefficients that
accounted for the differing diffusion rates of heat and salinity. Frazil...
As part of a study of the large-scale response of coastal sea level to atmospheric forcing along the west coast of North America during June–September 1973, Halliwell and Allen calculate space- and time-lagged cross-correlation coefficients Rτζ between adjusted sea level ζ at fixed alongshore locations ζ(y0) and the alongshore component...
Empirical orthogonal function (EOF) analysis in the frequency domain is extended to complex time series. EOFs are calculated from the eigenvectors of the band-averaged rotary cross-spectral matrix. This gives EOF amplitude and phase for negative and positive frequencies, corresponding to clockwise and anticlockwise rotation for the hodograph model. Rotary EOF...
The generation of an alongshore mean flow by the nonlinear interaction of forced barotropic shelf waves over a continental margin is studied using a wind-forced, ƒ-plane model with bottom friction in an attempt to develop a model for poleward eastern boundary undercurrents. It is assumed that the Rossby number is...
The response of alongshore currents V over the continental shelf and of coastal sea level ζ along the
Pacific coast of North America to atmospheric forcing on large alongshore scales (100-2000 km) during
May-July 1981 (Coastal Ocean Dynamics Experiment (CODE) 1) and May-July 1982 (CODE 2) has
been studied using...
A large-scale west coast shelf experiment called SuperCODE
was conducted off Oregon and California between February 1981
and April 1984. Current and temperature measurements were made
from subsurface arrays off Coos Bay (43°N), Crescent City
(42°N), Eureka (41°N), Half Moon Bay (37.5°N) and Purisima
Point (34.70), between February 1981 and...
This thesis reports on the growth and characterization of p-type
pseudomorphic A1GaAs /InGaAs /GaAs modulation doped field effect transistor
(MODFET) structures. A series of different p-type MODFET structures were grown
with a systematic variation of the indium mole fraction and quantum well width of
the InGaAs channel region. Extensive characterization...
