Examples include upwellings around the Galapagos Islands and the Seychelles Islands, which have major pelagic fisheries. [4] Upwelling could occur anywhere as long as there is an adequate shear in the horizontal wind field. For example when a tropical cyclone transits an area, usually when moving at speeds of less than 5 mph (8 km/h). The ...
Rather, the primary source of nitrate into the estuary is from ocean exchange caused by wind-driven seasonal upwelling off the Oregon and Washington coasts. [8] This influx of nitrate, generally the primary limiting nutrient to biological communities in the estuary, is an important driver of primary productivity in estuarine plumes of river ...
The task of defining and mapping these ecoregions was carried out by the Oregon Ecoregion Project, a collaborative effort involving the EPA, the United States Geological Survey (USGS), the United States Forest Service (USFS), and other state and federal agencies. The new classification system they developed may differ from previous frameworks ...
The upwelling front is accompanied by a geostrophic upwelling jet. During the summer upwelling season, the southward flowing jet off of central Oregon lies mid-shelf at approximately the 100-m isobath. [14] Its near-surface speed averages 0.35 m/s, with individual events exceeding 0.80 m/s. [15] This is faster than the surrounding water ...
