Western boundary currents are very strong. 1996 - 2023 National Geographic Society. Between 0 and 600m (01,969ft), many species of zooplankton occupy this space within the OMZ. Together, La Nia and El Nio are the "cold" (La Nia) and "warm" (El Nio) phases of the El Nino-Southern Oscillation (ENSO). North-central Peru's fishery is primarily composed of one stock of anchoveta. Even these complex models, however, cannot predict the exact intensity or duration of an El Nio, nor can they predict how areas will be affected. In the Indian Ocean, the westward-flowing South Equatorial Current is well-developed only south of the equator. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that "wells up" from below. As current moves down the water column, some water flows in a direction opposite to the surface current (Fig. So, less important. Each successively deeper layer of water deflects further to the right of the wind in the Northern Hemisphere and to the left of the wind in the Southern Hemisphere. The rotational motion of the earth influences ocean currents. If the seafloor is shallower than this depth the net direction of water movement is not as deflected compared to the air current. Fishermen off the west coast of South America were the first to notice appearances of unusually warm water that occurred at year's end. With the fish gone, sea birds that depend on them may die or go elsewhere. In the process they also transport nutrients, salt and other chemicals and help regulate the planet's weather, climate and marine ecosystems. This can produce hazardous shipping conditions, for it can carry icebergs into an area of the Atlantic where they are not usually found. THE BENGUELA CURRENT is located in the southern part of the Atlantic Ocean and moves northward from the western coast of South Africa, Namibia, and. In the Indian Ocean the place of a north equatorial current is taken by the Monsoon Current. "The Humboldt Current System: Ecosystem components and processes, fisheries, and sediment studies.". Wind-produced ocean currents move at an angle to the direction of the wind. 3.14 are listed in Table 3.1 and will be referred to in the following discussion. salinity. These are winds that drive the system of surface currents in the ocean. Understanding currents is important for navigating traffic in harbors and shipping lanes. A pronounced front, unique to the Indian Ocean, at 10 S, marks the limit of the monsoon influence. The Humboldt Current is a cold ocean current which flows north along the coasts of Chile and Peru, then turns west and warms as it moves out into the Central Pacific. In the equatorial Pacific, the trade winds blow the North and South Equatorial Currents towards the west, while Ekman transport causes the upper layers to move to the north and south in their respective hemispheres. A 10-m long wave will have elliptical orbits in water that is 50 m deep. [1], The Humboldt current, occupying the upper ocean, flows equatorward carrying fresh, cold Sub-Antarctic surface water northward, along the outskirts of the subtropical gyre. This is due to changes in the availability of each species habitat.
