Sediment Movement on the Continental Shelf near Washington and Oregon.

چکیده
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 kilometers per year westward away from the coast.

Distribution of DDT and other persistent organic contaminants in Canyons and on the continental shelf off the central California coast.
Sediment samples were collected to delineate the distribution of contaminants along the central California coast. Sampling included a variety of Canyons and shelf/slope areas to evaluate contaminant transport patterns and potential delivery to Canyons and the continental slope to a depth of 1200 m. Sediments were collected and analyzed for organic contaminants using standard techniques of the N...
متن کاملSediment distribution and sedimentary processes across the Antarctic Wilkes Land margin during the Quaternary
The study of existing cores collected across the Wilkes Land margin provides us with a better understanding of the sediment distribution and processes across this margin during the Holocene, and during Pleistocene glacial and interglacial cycles. Holocene depositional rates are high in deep (>1000m) inner-shelf basins where diatomaceous ooze is deposited at estimated minimum sedimentation rates...
متن کاملReconnaissance Survey of the Irish Continental Shelf/Shelf Edge Atlantic Irish Regional Survey (AIRS) 1996 A GLORIA Survey of the Irish Continental Margin
The Atlantic Irish Regional Survey (AIRS96) sidescan sonar survey was carried out in August 1996. Covering an area of 200,000 km 2 it represented the largest reconnaissance seabed survey of the Irish Continental Shelf region. It covered both margins, together with much of the basin floor, of the Irish sector of the Rockall Trough and extended into the northern part of the Porcupine Seabight. Th...
متن کاملThe continental shelf benthic iron flux and its isotope composition
Benthic iron fluxes from sites along the Oregon–California continental shelf determined using in situ benthic chambers, range from less than 10 lmol m 2 d 1 to values in excess of 300 lmol m 2 d . These fluxes are generally greater than previously published iron fluxes for continental shelves contiguous with the open ocean (as opposed to marginal seas, bays, or estuaries) with the highest fluxe...
متن کاملElevated Fe(II) and dissolved Fe in hypoxic shelf waters off Oregon and Washington: an enhanced source of iron to coastal upwelling regimes.
There has been a growing interest in the cause and impact of hypoxic regions known as "dead zones" that have increasingly appeared along the west coast of the United States and have caused widespread destruction to the crab and fishing industry in this upwelling region. Here, we present results that demonstrate that the hypoxic conditions in the water column over the continental shelf result in...
