The oceanic phenomenon of upwelling along the Oregon coast is
examined. Upwelling in both the open ocean and coastal regions is
discussed. An idealized model is used, envisaging the ocean off
Oregon to consist of homogeneous surface and deep layers separated
by a pycnocline. The equations of motion are solved to yield the vertical
velocity at the base of the surface layer. A comparison is made
between the model and results inferred from hydrographic data.
In the open ocean region qualitative agreement is observed between
the wind stress curl and the depth of the surface layer. Geostrophic
meridional transports relative to the 1000 decibar surface
were computed and found to be of the order of the uncertainty. In the
coastal upwelling region surface layer zonal transports were computed
from the meridional component of the mean wind stress and
compared with values inferred from oceanographic data. Coastal upwelling
along the Oregon coast is clearly associated with the northerly
(longshore) component of the wind stress. / Graduation date: 1964
