Air and water masses moving over the surface of the earth are only weakly bound to it by friction and so are subject to the Coriolis force. What are five factors that affect current flow? 2. Ocean circulation is the large scale movement of waters in the ocean basins. The ocean currents rely on the temperatures of the air, gravity, carbon dioxide levels (found in water and air) and lastly the salt content or density of the water itself. The orange and red shadings in the middle of the map correspond to the warmer waters in tropics. From Portugal to Senegal, use the _____ Current. The Benguela Current is the eastern boundary current of the South Atlantic subtropical gyre (Peterson and Stramma 1991, Wedepohl et al. The deep waters of the oceans come from the surface water cooled in the polar region. Ocean currents are streams of water flowing through the ocean, driven by wind or by the mixing of waters of differing densities. Abraham Lincoln, 4.

Using favorable currents as much as possible, start your voyage in Britain, and chart your course by sketching your path on the map and labeling the currents used in the voyage. Deep below the surface, however, ocean circulation is primarily driven by changes in seawater density, which is determined by salinity and temperature. But those that move north and south act like conveyor belts, transporting warm water to the polar regions and carrying cooler water back toward the equator. Right now its super slow because it loops the code that creates the map and axis with the high resolution coastline (the coastline slows this down significantly) and m_quiver plot each iteration.
