Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...
Velocity measurements from 17 deployments of moored acoustic Doppler current
profilers obtained during four summer upwelling seasons are used to describe the crossshelf
divergence of Ekman transport in the inner shelf off Oregon. For each deployment
the measured surface and bottom cross-shelf transports were compared with estimates
of the theoretical...
Realistic hindcast of the Columbia River estuarine-plume-shelf circulation in summer
2004 using the Regional Ocean Modeling System nested within the Navy Coastal Ocean
Model (NCOM) is quantitatively evaluated with an extensive set of observations. The
model has about equal skill at tidal and subtidal properties. Tidal circulation and water
properties...
The northern California Current System is impacted by two primary freshwater
sources: the Strait of Juan de Fuca and the Columbia River. The Columbia is frequently
bidirectional in summer, with branches both north and south of the river mouth
simultaneously. We describe the interaction of these two warm Columbia plumes...
Numerical simulations of the Hudson River estuary using a terrain-following, three-dimensional
model (Regional Ocean Modeling System (ROMS)) are compared with an
extensive set of time series and spatially resolved measurements over a 43 day period with
large variations in tidal forcing and river discharge. The model is particularly effective at...
