Ocean currents play a vital role in transferring energy across Earth’s oceans. They facilitate the redistribution of heat from the equator to the poles, which in turn affects climate and weather patterns. When it comes to the distribution of sea ice, ocean currents have a significant impact on its movement and melting. As sea ice forms and melts in the saline ocean water, it is carried by prevailing winds and ocean currents. For example, in the Arctic, newly formed ice is pushed into warmer waters by winds and currents, contributing to the expansion of the ice sheet. Conversely, during springtime, the melting of ice creates a layer of fresh seawater that acts as insulation, protecting incoming ice from warmer subsurface waters. This has implications for the survival of the ice in the following winter. The interaction between sea ice and ocean currents is crucial for determining the extent of sea ice and can be utilized to predict its growth and transport. Consequently, it is a valuable tool for climate scientists and industries that rely on accurate climate data. The warming of oceans and the melting of sea ice can also disrupt ocean currents, potentially leading to catastrophic consequences. Therefore, ocean currents are integral to the distribution and behavior of sea ice, ultimately impacting Earth’s climate and environment.

Large-scale surface ocean currents are driven by global wind systems that are fueled by energy from the sun. These currents transfer heat from the tropics to the Polar Regions, influencing local and global climate. The water, now a sub surface current, moves in predictable patterns throughout the deep ocean, slowly mixing with less dense water. Energy transfer is an essential function played by ocean currents. By transferring heat energy around the globe, ocean currents shape both local weather conditions and global climate. Ocean currents act as conveyer belts of warm and cold water, sending heat toward the Polar Regions and helping tropical areas cool off. The world's ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun's radiation is absorbed by the ocean. Energy is redistributed in the oceans by ocean currents. This is permanent or continuous movement of ocean water from one place to another. 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. Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. The colder and saltier the ocean water, the denser it is. The greater the density differences between different layers in the water column, the greater the mixing and circulation. Density differences in ocean water contribute to a global-scale circulation system, also called the global conveyor belt. By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places. Cold ocean current flows from the polar to the equatorial regions. During this process, iceberg from the polar areas gets carried along the current. This, in turn, poses threat to marine routes where frequent movement of ships takes place. The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect a force that results from the rotation of the Earth deflects them. These surface currents play an important role in moderating climate by transferring heat from the equator towards the poles. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water.
