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...

Tidal-band and high-frequency internal variability on the central Oregon inner shelf

Creator:

Suanda, Sutara H.

Abstract:

Analogous to ocean surface waves, waves in the ocean interior also experience steepening, breaking, and dissipation as they approach the coastline. Much less is known about this internal beach. In this work, extensive moored Acoustic Doppler Current Profiler and temperature/salinity data together with optical remote sensing are combined to describe...
