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...
Three-dimensional ecosystem response to wind forcing on the continental shelf off Oregon is studied using a five-component nitrogen-based ecosystem model coupled to a high-resolution circulation model. We investigate, in particular, the influence of timedependent winds and alongshore variations in shelf topography for summer 2001 during the time period of the...
The behavior of three ecosystem models is analyzed for upwelling off the Oregon coast as a function of the number of model components. The first ecosystem model includes dissolved inorganic nitrogen-phytoplankton-zooplankton (NPZ), the second (NPZD) adds detritus, and the third (NNPZD) splits the nutrients into nitrate and ammonium. The models...
We conduct modeling studies of the coastal circulation off northern California in the vicinity of the Eel River (40.6 degreesN, the site of the 1995-2000 Strata Formation on Margins (STRATAFORM) marine geology observational program) using a series of nested hydrostatic primitive equation models to aid in the understanding of the...
The finite amplitude nonlinear behavior of the coastal transition zone (CTZ) jet, assumed to be governed by quasi-geostrophic dynamics, is studied utilizing numerical experiments in an idealized geometry. Finite difference solutions to initial value problems are obtained for a stratified, six-layer fluid in a periodic, flat bottom, f plane channel....
We study the statistical properties of the coastal wind field along the west coast of North America for
two summers. 1981 and 1982 Coastal Ocean Dynamics Experiments 1 and 2, respectively), and the
Intervening winter using measured winds and geostrophic winds calculated from Fleet Numerical Oceanography
Center atmospheric pressure analyses....
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...
We simulated the erosion and accretion of a natural beach using a wave-resolving
eddy-diffusive model of water and suspended sediment motion in the bottom boundary
layer. Nonlinear advection was included in this one-dimensional (vertical profile) model
by assuming that waves propagated almost without change of form. Flows were forced by...
The sensitivity of model-produced time-dependent wind-driven circulation on the
continental shelf to the turbulent closure scheme employed is studied with a twodimensional
approximation (variations across-shelf and in depth) using the Princeton
Ocean Model. The level 2.5 Mellor-Yamada closure (MY), k-ε closure, and K-Profile
Parameterization schemes are used to evaluate the...
A two-part modeling study of the wind-forced flow on the continental shelf off
northern California in the region (37°–40°N) of the Coastal Ocean Dynamics Experiment
(CODE) is pursued. This paper involves a process-oriented study with idealized wind
stress forcing. Gan and Allen [2002] involves forcing with observed winds and heat...
