What current brings cold water to the ocean surface?
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.
What brings electeic current to your home?
deep, cold water to the ocean surface
What causes unwelling?
Unwelling refers to the upward movement of water from the ocean depths to the surface, often driven by various factors such as wind patterns, ocean currents, and temperature differences. It typically occurs in regions where surface water is displaced or where warm surface water is replaced by colder, nutrient-rich water from below. This process can enhance biological productivity in marine ecosystems, as it brings nutrients to the surface that support phytoplankton growth. Changes in climate and ocean circulation can also influence unwelling patterns.
How does the sun provide energy for surface ocean currents?
The sun heats the water, causing cold / hot circulation, and evaporation. It also heats the air, causing wind, which also moves currents.
Fish are abundant in areas where the ocean is upwelling because it -?
Fish are abundant in areas where the ocean is upwelling because the upwelling brings nutrient-rich water to the surface, which supports the growth of phytoplankton. Phytoplankton is the base of the marine food chain, providing food for small fish which in turn attract larger fish and predators. This creates a productive and diverse ecosystem where fish thrive.
How does atmospheric forcing impact the dynamics of ocean circulation?
Atmospheric forcing, such as wind and temperature changes, can affect ocean circulation by influencing the movement of surface waters and the formation of ocean currents. These forces can drive the mixing of water masses, impact the distribution of heat and nutrients, and play a role in shaping the overall circulation patterns of the ocean.
Describe the two steps of upwelling?
Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
What is deep water formation?
Deep water formation is the process by which surface waters in the ocean cool and become denser, sinking to the depths of the ocean. This sinking of dense water drives the global thermohaline circulation, which plays a key role in distributing heat and nutrients around the world's oceans. Deep water formation is crucial for ocean circulation and climate regulation.
How does water sink to the bottom of the ocean and then rise to the surface again?
Water sinks to the bottom of the ocean due to its density, which is affected by temperature and salinity. Cold and salty water is denser and sinks, while warm and less salty water rises. This movement is known as ocean circulation, where water moves in a continuous cycle from the surface to the depths and back again.
Explain why the ocean surface water temperature is usually cooler after the passage of a hurricane?
After a hurricane passes, the ocean surface water temperature is usually cooler due to the intense mixing of water caused by the storm's strong winds and turbulent waves. This mixing brings deeper, colder water up to the surface, replacing the warmer surface water. Additionally, the evaporation of water during the hurricane can further cool the surface temperature. The combined effects of these processes result in a significant drop in the temperature of the ocean's surface after the storm.
What brings energy to ocean water?
tides
What is the cause of surface currents?
The circulation of cold and warm water between the poles and the equator, and the rotation of the earth, cause ocean currents to flow.
