Oregon Coastal Observing System

Since 1997, a growing system of sustained coastal measurements,
together with a high-resolution, data-assimilating coastal modeling
program, have been used off Oregon to study the response of the
coastal ocean to forcing at a range of space and time scales. The
measurements include a large array of HF radars, which permit
time-series mapping of the surface circulation over most of the
Oregon coast; both long-term and short-term moored components,
which provide time-series sampling through the water column; and
repeat hydrographic, ADCP and surface drifter sampling, including
the Newport Hydrographic Line (which has been sampled since the
1960s). At interannual frequencies, these measurements show changes
in the alongshore circulation over the continental slope accompanying
ENSO. At seasonal and storm frequencies, the strength and persistence
of spatial patterns in wind-driven currents and the importance
of bathymetry in steering the circulation are seen. Discovery of
episodic phenomena, such as the recent finding of a hypoxic pool
and associated die-off of fish and crabs on the continental shelf
off Heceta Head, are made possible by repeated sampling.
