Examine Global Surface Currents
When most people think about the movement of ocean water, they think of waves or tides. Ocean surface currents are less visible, but can move water as much as 100 kilometers (62 miles) per day and distribute everything they contain to distant oceans and seas. This interactive feature illustrates the patterns of ocean currents and the global wind patterns that drive them. Cool and warm currents are indicated by colored arrows; rolling a mouse over the map reveals global wind patterns, indicated by another set of arrows. A background essay and discussion questions are included.
