Ocean Currents- any continuous flow of water across a broad path in the ocean

-the current can be in any direction, but is usually horizontal

Section 1: How do you track currents? deep_ocean.jpg
  • flow
  • temperature
  • salinity
  • sea life
  • suspended solids (minerals)
Section 2: Ocean Currents- the basics
-Surface Currents are drawn by wind, Earth's rotation, and the Coriolis Effect
-The north to south movement of water is called the Coriolis Effect
-two sets of winds are involved in forming ocean currents: trade winds and westerly winds
-trade winds affect the part of each current circle that occurs near the equator
-westerly winds drive the polar portion of the current circles
-the temperature is different from the poles to the equator
-Westerlies blow from:
  • the southwest in the Northern Hemisphere
  • the northwest in the Southern Hemisphere
Section 3: Equatorial Counter Current
-water sloshes east after hitting the continent
Section 4: Labrador Current
-very cold
-very salty
-today has unknown amounts of fresh water
Section 5: Gulf Stream
-is the most powerful warm water current on the planet
-is warm and salty
