  1. The Canary Current Geoffrey Grek

  2. Canary Current Stats • Flows North to South from 30°N to 10°N and offshore to 20°W • Very wide ~1000 km • Cold water due to upwelling along coast • On average 500 m deep and flows at 10-15 cm/s • Canary Island Archipelago reaches depth of 3000 m and impedes path of current

  3. Eastern Boundary Current Part of the North Atlantic Subtropical Gyre Flows southwest along African coast Causes upwelling on the African coast The Canary Current

  4. Eastern Boundary Current Part of the North Atlantic Subtropical Gyre Flows southwest along African coast Causes upwelling on the African coast The Canary Current

  5. Driven by the trade winds Current velocity dependent on trade wind velocity Flow obstructed by Archipelago Island Always flows towards equator The Canary Current

  6. Form along the coastal boundary Length scales of 100 to 300 km Kinetic Energy values are less than 100 cm2 s2 Canary Current Eddies

  7. Canary Current Eddies

  8. Northward mass transport is positive in Figure on right Mostly southward mass transport Northward mass transport is caused by Equatorial countercurrent Mass Transport
