Ocean Currents and Their Impact

Front

Warm currents on the eastern sides of continents produce warm, humid conditions.

Back

climate influence

Front

Water sinks in high-latitude regions, initiating these currents that help regulate the planet’s climate.

Back

deep currents

Front

Measuring average flow rates of surface currents can be challenging due to their variability.

Back

due to high variability, measuring is difficult

Front

Density-driven circulation is responsible for mixing deep ocean water masses.

Back

causes vertical mixing

Front

Floating device method

Back

A floating device is released into the current and its position is tracked over time
