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 ...
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 ...
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 ...
Seasonal winds cause tides and upwelling that influence nutrients and the biogeochemistry of Coos Bay estuary. One third of macrophyte production in the estuary is attributed to upwelling. [22] In the summer, wind primarily comes from the North along the Oregon coast, bringing up nutrient-rich deep water and boosting primary production. [23]
Alaska: Akutaq. A specialty of Native Alaskans, akutaq is sometimes called Alaskan ice cream. It's a dessert made with fresh local berries, sweetener, and animal fat, and sometimes dried fish or meat.
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 ...
Oregon has the fifth highest personal income tax in the nation. According to the U.S. Census Bureau, Oregon ranked 41st out of the 50 states in taxes per capita in 2005 with an average amount paid of 1,791.45. [62] A few local governments levy sales taxes on services: the city of Ashland, for example, collects a 5% sales tax on prepared food. [63]
