how does the south equatorial current affect fishing

This is indeed the case in tropical waters, and as a result they are very unproductive. Gulf Stream, warm ocean current flowing in the North Atlantic northeastward off the North American coast between Cape Hatteras, N.C., U.S., and the Grand Banks of Newfoundland, Can. Omissions? Three factors aid the formation of Counter-Equatorial current. In the Pacific and Atlantic Oceans, it extends across the equator to about 5 degrees north. [1] This energy forms mesoscale eddies which extend 600800km (370500mi) offshore. Gyres in the Northern Hemisphere travel in clockwise directions while gyres in the Southern Hemisphere travel in counter-clockwise directions. The North Equatorial Current (NE) and the South Equatorial Current (SE) flow in the same direction. During the Indian wet monsoon, the prevailing winds blow ____ in the ______. In the open ocean, turbulent mixing of surface water or surface waves often disrupt the Ekman spiral. For example, if the wind blows from the south to the north, the current flows 90 to the rightdirectly east. Water movement in surface currents is called Ekman transport. And this creates a. Piling up of water in the western pacific due to trade winds. It is predominantly controlled by the winds. Following the pattern in the northern hemisphere, the south equatorial current flows from east to west and turns southwards as the East Australian current. [1] The major catches include: sardines, anchovies, mackerel, hake, and squid. Here are 4 ways we use it. The Southern Oscillation is a see-saw shift in surface air pressure between the eastern and western halves of the Pacific. The great Dust Bowl drought of the 1930s is thought to have been caused by a decade of La Nia-like conditions and was likely responsible, in part, for the severe drought in the American Midwest in 1988. southeast trade winds maintain the South Equatorial Current, which flows toward the west where it divides into two branches: one that continues to the Northern Hemisphere and enters the Caribbeantogether with a small amount of water from the North Equatorial Currentas the Guiana (Guyana) Current and one that turns south Read More Indian Ocean [1] The main flow of the current veers offshore in southern Peru, as a weaker limb continues to flow equatorward. Individual surface currents are identified in Table 3.1. This deflection of water motion is due to the Coriolis effect from the earths rotation (Fig. Required fields are marked *, PMF IAS Environment is a One-Stop solution for all your needs concerning the subject of Environment for the UPSC Civil Services Exam! The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit. Fig. Coastal upwelling is the main factor contributing to the high biological productivity of the Humboldt current. Directly on the equator, the winds reverse twice a year due to the monsoons, and so the surface current can be either eastward or westward. Kelp forests also depend on cool, nutrient-rich water for survival and growth. Around 18th parallel south the fresh, cold waters begin to mix with the warm, high salinity Subtropical Surface waters.
