How do ocean currents impact the world?
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..
Why is studying the ocean important?
Information from deep-ocean exploration can help predict earthquakes and tsunamis and help us understand how we are affecting and being affected by changes in Earth’s environment. Ocean exploration can improve ocean literacy and inspire young people to seek careers in science, technology, engineering, and mathematics.
How do ocean currents help people?
Ocean currents play a role in the distribution of pollution, such as oil spills. Oil and fuel tends to remain on the surface of the ocean, so knowing the current helps determine where such pollution might travel. Safety operations such as rescues use currents to help look for missing people or other objects in the sea.
What are the disadvantages of ocean currents?
Disadvantages – Sometimes there will not be a lot of waves (which means no energy), It could interfere with ocean ecosystems in the area of the currents, and the temperature is raised wherever ocean currents are happening (which could also ruin an ecosystem).
What happens if ocean currents stop?
If it continues to slow, that could have profound consequences for Earth’s inhabitants. Studies suggest it would mean much colder winters and hotter summers in Europe, changing rainfall patterns in the tropics, and warmer water building up along the U.S. coast that can fuel sea level rise and destructive storms.
Does ocean energy cause pollution?
Environment Friendly Also, unlike fossil fuels, creating power from waves creates no harmful byproducts such as gas, waste, and pollution.
What is Ocean Energy and how does it work?
Ocean thermal energy is generated by converting the temperature difference between the ocean’s surface water and deeper water into energy. Ocean thermal energy conversion (OTEC) plants may be land-based as well as floating or grazing.
Why do people track currents?
Results from current surveys are used to improve tidal current predictions and to support new operational forecast models. An observer stands on a ship, throws the drifter into the water, and then measures the time that it takes that object to move along the side of a ship.
How are currents important?
Currents are important in marine ecosystems because they redistribute water, heat, nutrients, and oxygen about the ocean. At the same time, currents inevitably sweep over and carry off living organisms.
What are the two main categories of ocean currents?
There are two type of Ocean Currents:Surface Currents–Surface Circulation.Deep Water Currents–Thermohaline Circulation.Primary Forces–start the water moving.The primary forces are:Secondary Forces–influence where the currents flow.Solar heating cause water to expand.More items…
What are the advantages and disadvantages of ocean thermal energy?
Electric power generated by OTEC could be used to produce hydrogen. DISADVANTAGES:-Capital investment is very high. Due to small temperature difference in between the surface water and deep water, conversion efficiency is very low about 3-4%.
How do scientists study currents?
The large-scale patterns formed by drifting concentrations of phytoplankton show scientists the location and movement of ocean surface currents. … Scientists in physical oceanography use surface temperature measurements and the location of phytoplankton to identify the location and movement of ocean surface currents.
Why do ocean currents occur?
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. … These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
What are the 5 major ocean currents?
There are five main gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.
What are the advantages of ocean currents?
Ocean currents function as a system of global transportation, carrying animals, plants and even people and cargo from place to place. Oceanographers have mapped these currents. The maps not only help people understand the ocean, but they help people from many professions perform daily tasks.
