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
The Canary Current Eastern Boundary Current Part of the North Atlantic Subtropical Gyre Flows southwest along African coast Causes upwelling on the African coast
4
The Canary Current Eastern Boundary Current Part of the North Atlantic Subtropical Gyre Flows southwest along African coast Causes upwelling on the African coast
5
The Canary Current Driven by the trade winds Current velocity dependent on trade wind velocity Flow obstructed by Archipelago Island Always flows towards equator
6
Canary Current Eddies Form along the coastal boundary Length scales of 100 to 300 km Kinetic Energy values are less than 100 cm 2 s 2

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