What Would Cause Ocean Circulation to Slow Down

Scientists believe that part of this slowing is directly related to our warming climate, as melting ice alters the balance in northern waters. Its impact may be seen in storms, heat waves and sea-level rise.

What causes ocean currents to slow down?

In the north, water tends to be cold and salty, which makes it dense and allows it to sink and circulate. However, increased rainfall and the melting of Arctic ice sheets and glaciers are adding more freshwater and making the polar waters less dense. As a result, there is a slowing down of the current.

What factors affect ocean circulation?

The ocean has an interconnected current, or circulation, system powered by wind, tides, the Earth’s rotation (Coriolis effect), temperature, salinity, and water density differences. The topography and shape of ocean basins and nearby landmasses also influence ocean currents.
