What ocean currents are more commonly found along west coast of continents?

The ocean currents commonly found along the west coasts of continents are typically cold currents, such as the California Current along the west coast of North America and the Peru Current along the west coast of South America. These currents flow from higher latitudes towards the equator, bringing cooler temperatures and nutrient-rich waters that support diverse marine ecosystems. The influence of these currents often results in upwelling, which enhances productivity and affects local climates.
