How does the ocean lose and gain energy?

How does the ocean lose and gain energy?

The main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels.

How does the ocean gain energy?

The ocean can produce two types of energy: thermal energy from the sun’s heat, and mechanical energy from the tides and waves. The sun’s heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy.

How does downwelling work in deep ocean currents?

Cooling or evaporation of fresh water from the sea surface makes surface water dense. This causes the surface water to undergo downwelling. Downwelling of cold, dense water pushes deep water along. This drives thermohaline circulation.

How does ocean currents affect energy balance?

Energy is moved from areas of surplus to those of deficit, with warm currents transporting warm water polewards and cold currents taking colder water to lower latitudes. It holds onto this heat for longer than the land does and the ocean currents move this heat around, from the tropics to higher latitudes.

What kind of energy does an ocean wave possess?

Ocean Wave Energy (Hydrokinetic) Ocean waves contain tremendous energy potential. Wave power devices extract energy directly from the surface motion of ocean waves. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves along the shoreline.

Where does downwelling occur in the ocean?

Downwelling occurs in areas such as in the subpolar gyre of the North Atlantic where several surface currents meet, where cold waters meet warmer waters, such as along the outermost boundary of the Southern Ocean where cold Antarctic water sinks below warmer South Pacific and South Atlantic waters.

How do ocean currents redistribute heat energy?

Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. The ocean doesn’t just store solar radiation; it also helps to distribute heat around the globe.

Which ocean condition would result in downwelling?

What causes upwelling and downwelling in the ocean?

In any coastal upwelling location, if the winds reverse, surface water moves towards the shore and downwelling is the result. Upwelling can also occur due to geological features of the ocean floor. For example, as deep water currents encounter or other raised features, the water is forced upwards, bringing nutrient-rich water to the surface.

How does deep water movement affect ocean currents?

Again, to fill the void created by moving of the surface water, deep water upwells through upwelling zone . In upwelling currents, vertical water movement and mixing brings cold, nutrient-rich water toward the surface while pushing warmer, less dense water downward, where it condenses and sinks.

Why does upwelling occur in deep water currents?

Upwelling can also occur due to geological features of the ocean floor. For example, as deep water currents encounter or other raised features, the water is forced upwards, bringing nutrient-rich water to the surface.

How are ocean currents related to global circulation?

Surface Currents amount to only 8-10% of the global oceanic current flow. Differences in water density, resulting from the variability of water temperature (Thermo) and salinity (haline), also cause ocean currents. This process is known as thermohaline circulation.
