Benthic flux of oxygen and nutrients across Oregon/California shelf sediments
A free vehicle benthic chamber has been used to define benthic nutrient fluxes on the Southern Oregon and Northern California shelf (90–200 m). We measured fluxes on two occasions, in the spring and fall of 2007, to assess variability in fluxes and bioirrigation rates. Chambers were also employed to assess the impact of changing oxygen content on benthic fluxes. Oxygen uptake rates are similar ...
متن کاملSediment Movement on the Continental Shelf near Washington and Oregon.
The nuclides zinc-65 and cobalt-60 associated with river-borne particulate matter are incorporated in sediment on the Continental Shelf near the Colum- ia River. Changes in the relative concentrations of zinc-65 and cobalt-60 and in the ratio of the activity of zinc-65 and cobalt-60 suggest that radioactive sediment moves northward 12 to 30 kilometers per year along the shelf and 2.5 to 10 kilo...
متن کاملWave-Driven Inner-Shelf Motions on the Oregon Coast*
Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using observations from the central Oregon coast to identify the wave-driven return flow present and quantify the potential bias of wind-driven across-shelf exchange by unresolved wave-dr...
متن کاملA dye tracer reveals cross-shelf dispersion and interleaving on the Oregon shelf
[1] A fluorescent dye tracer was injected into the pycnocline on the Oregon shelf at a depth of 9–10 m. It spread rapidly cross-shelf as two distinct layers, one above the other in the water column, split by interleaving dye-free water. The vertical scale of these layers, and associated density steps, was 1–2 m, and the horizontal extent of interleaving exceeded 1.6 km after an inertial period....
