Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

Creator:

Adams, Katherine A.

Abstract:

Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...

Inner-shelf circulation off the central Oregon Coast

Creator:

Kirincich, Anthony R.

Abstract:

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...

The effect of river discharge and wind forcing on the Oregon coastal ocean during fall and winter

Creator:

Mazzini, Piero Luigi Fernandes

Abstract:

Freshwater provided from river discharge influences the dynamics and circulation of most continental shelves around the world. It has profound effects on the transport and fate of materials and substances originated from rivers and estuaries, as well as on the ocean biogeochemistry and marine ecosystems. The effect of buoyancy forcing...
