TL;DR (Too Long; Didn't Read) Two major kinds of currents define the planet's oceans: surface currents driven by wind and deep-water currents driven by variations in … The current's direction and speed depend on the shoreline and the ocean floor. Even though the wind became one of the factor that affect the surface current but the effect is quite big. Beside it helps distribute the nutrient through the ocean evenly, it also has another function. Because of this, the temperature in the pole is not extremely cold. Both bad and good impact can we do to our ecosystem just like a simple example of throwing garbage to the ocean. At the surface the wind, earth rotation, density gradients, gravity and pressure gradients determine the currents. The action created by tides can impact both types of currents by modifying depth levels and water displacement. Surface Currents and Deep Ocean Currents. Now, moving on to another deep ocean current type of down-welling. Tides are, in fact, the most important of all the oceanic movements because tidal currents affect the whole water mass from the sea surface to the bottom. They are also called as thermohaline circulation. Of all the movements in the oceanic water, ocean currents are the most important. Like the planetary winds, currents too are deflected … 2. These waters are the upper 400 meters of the ocean.  They are found below 400 meters and make up about 90% of the ocean. Currents can be distinguished from tides, regular increases and decreases in the level of the sea surface. Currents, Waves, and Tides oh my. Then, deep ocean currents occupy the other 90%. Movements of ocean water are also affected by external forces like the sun, moon and the winds.The major movements of the ocean waters can be classified into three. Or what species of fish that has a migration against the ocean currents. Early on, the study of currents was important due to shipping concerns: A knowledge of ocean currents allowed sailors to safely reach their destination, or to get there more quickly. When human throw garbage to the ocean, the garbage such as plastic waste will polluting the ocean and it will be accumulated in the sea bottom and it will create sedimentation in the ocean’s bottom. Taking an example of tides current, rip current, long-shore current, and etc and most of them are classified into the surface ocean current. One is the rise and fall of the tides, which is driven by the gravitational attraction of the sun and moon on Earth's oceans. Ocean currents are located at the ocean surface and in deep water below 300 meters (984 feet). This video explains in detail the phenomenon of ocean currents and their role in nature. Surface means the current will only exist in the ocean water surface. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet. Warm currents are masses of warm water with higher temperatures moving away from the equator. Names, direction, nature....and what not! This cold, dense, saltier water sinks to the seafloor, replaced by surface waters that repeat the process. There are two types of deep ocean current movement. The following factors cause ocean currents: (a) The prevailing winds are the major cause of the ocean waters moving in a definite direction. For example, surface currents control the motion of about 10% of the upper ocean space. Even though down-welling and surface ocean water current look alike but they are two different things. When you put a rock inside the hose, the water will move upward and it flows harder than before because it was looking for a hole to be passed. Competitive sailors also closely surface currents to improve race results. Finally, the lesson contrasts the differences between surface and deep ocean currents. The current help our climate to stay in balance because it will move the water with a certain temperature to another places that has a different temperature. The large-scale circulation of these surface currents roughly mirrors the large-scale circulation of air, which most simply derives from unequal heating of the planet’s surface by the sun. Taking an analogy of a hose. This current can be affected by wind, weather condition and tides (because of gravity). One major example of an ocean current is the Gulf Stream in the Atlantic Ocean. Surface currents develop anti-clockwise spirals in the southern hemisphere. Warm Currents and Cold Currents: There are two types of ocean currents. This current can be affected by wind, weather condition and tides (because of gravity). 15 Qs . Due to this transfer of heat, climate near large bodies of water is often extreme and at times, unpredictable. We might not see it directly but it can also bring impact to us. Having reliable knowledge about the tides and tidal currents is important for navigating ships safely, and for engineering projects such as tidal and … You all know that the ocean water is never still. These sedimentation will change the ocean’s bottom structure. Term of Use | Privacy Policy | Adchoices | Disclaimer | Contacts us. More over if you read about whale, most of them are dive into a deeper part of the ocean in search of plankton and nutrient to fulfill their body needs. Distribution of ocean currents; Causes of ocean currents. Types of Ocean Currents Based on depth. Surface means the current will only exist in the ocean water surface. Ocean currents that occur at 328 feet (100 meters) deep or above usually are classified as surface currents. TL;DR (Too Long; Didn't Read) Two major kinds of currents define the planet's oceans: surface currents driven by wind and deep-water currents driven by variations in … 12 Qs . In our geography notes on the hydrosphere, we have seen the major movements of the ocean water. As the Earth rotates around the sun and the moon, the gravitational pull of each celestial body causes ocean levels to be slightly deeper at certain times. And also, hopefully through this article you can realize how important our role as a human inside the ecosystem. It can drives our ocean current into a different track and make it does such a chaos. The pushing action of these winds makes the waters flow as they do. Surface currents refer to movement of the top layer of ocean water – the upper 330 feet or so – primarily driven by wind. Ocean currents hugely impact humankind and the biosphere in general, first and foremost due to their influence on climate. She received a bachelor's degree in economics and management from Goucher College in Towson, Maryland. For sure this route is made based on the fish migration from one place to another places. From that nutrient, plankton in the upper part of the ocean can get another food source that keep them alive. The currents associated with the tides are called flood currents (incoming tide) and ebb currents (outgoing tide). Deep-water currents describe water movement patterns far below the ocean’s surface and the influence of the wind. The ocean has an interconnected current, or circulation, system powered by wind, tides, the Earth’s rotation (Coriolis effect), the sun (solar energy), and water density differences. With the existence of ocean current, water will move to one place to another places. Do not forget to keep following our website! Down-welling is a condition where the water from the ocean surface is going down. Knowing the ocean current is important for fisheries and another water transportation. The deeper part of the ocean you dive in, the more plankton and nutrient that you will find. Ocean CurrentsWaves and the ocean currents … Languages. Basically, gyres is a large form of ocean current. For example, the wind, tides, water density, rotation and even ocean floor topography influences currents in the oceans. Like the winds controlling them, these surface currents help redistribute heat at a planetary scale: Generally speaking warm water flows toward the poles and cold water flows toward the equator. Ocean Adaptations . Wind-driven circulation. The other types of currents, deep ocean currents, also known as thermohaline circulation or ocean conveyer belts. They are related to different characteristics of ocean waters, rotational mechanism of the earth, external factors or atmospheric factors, topographic characteristics of the coasts and ocean basins. Usually, the horizontal movement of ocean current is short. Theories 5. To let you know more about this I will explain it to you one by one. When you learn about the ocean surface current you will know about … These waters make up about 10% of all the water in the ocean. Origin of Ocean Tides 3. 20 Qs . Pressure gradients; Coriolis effect; Frictional forces; Geostrophic currents; Ekman layer; Two types of ocean circulation. Surface ocean currents are typically wind-driven, resulting in both horizontal and vertical water movement. Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or … Oceanic currents are found all over the globe and vary in size, importance, and strength. The wind can move about 400 m of the top ocean water and because of this, the wind affect the ocean current. When the moon, sun, and Earth line up, particularly strong tides (“spring tides”) result that can dramatically affect water levels. There are two type of Ocean Currents: 1.  Like surface currents, gravity plays a dominant role in the creation of deep water currents. They are: 1. She received her LEED accreditation from the U.S. Green Building Council in 2008 and is in the process of working towards an Architectural Hardware Consultant certification from the Door and Hardware Institute. Sverdrup measures current flow rates, where 1 Sv is equal to 10 to the 6th power cubic meters per second, or about 265 million gallons per second. Tidal currents, just like tides, are affected by the different phases of the moon. Ocean currents transfer heat from one part of the world to another, and this movement of heat affects the climate; Subjects. And because of that transport, the ekman transport also creating the ekman spiral where there is a water layers exist with a different direction and speed. Currents form rotating systems in the middle of major ocean systems called gyres. Large-scale surface ocean currents are driven by global wind systems that are fueled by energy from the sun. Water Currents. There are different types of movements of ocean water under the influence of different physical characteristics like temperature, salinity, density, etc. Which are upwelling and downwelling. Through the rotation of the water it self our climate is stay in balance because both side is always rotating and making the temperature in balance. Digital Vision./Digital Vision/Getty Images, NOAA: Ocean Service Education -- Currents: The Global Conveyor Belt, NOAA: National Weather Service -- Ocean Circulations. The good impact that we can feel up to now is that the existence of fish. Some of the more prominent currents include the California and Humboldt Currents in the Pacific, the Gulf Stream and Labrador Current in the Atlantic, and the Indian Monsoon Current in the Indian Ocean. They can move water horizontally and vertically and occur on both local and global scales. Introduction to Ocean Tides: Waves, currents and tides are of vital signifi­cance among various types of oceanic movements. When the structure is changed for sure it will affect the ocean current. The ocean surface current is the current that carry heat from one place to another places and make the temperature stay in balance. As you know that heat energy or in this case is the ocean water from equator region will move to the cooler place which is the polar region. DRAFT. The ocean current is not only being affected by natural phenomena but it also can be affected by human activities. Upwelling takes place in some coastlines along the equator. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. The moon’s force is much greater than that of the sun because it is 389 times closer to the Earth than the sun is. 1.6k plays . Anyways, thank you for reading this article until the end and also thank you for following our website. Waves 2. Cold currents are formed when the air circulating the eastern side of the subtropical high is blown over cold water mass and are then dragged toward the equator. When you learn about the ocean surface current you will know about gyres. Wind-driven circulation. Both types of ocean currents are measured using units called Sverdrup (Sv). The wind that caused the surface ocean water current is not as big as the wind that caused the down-welling. But not only that, we should know more about the ocean current. Horizontal surface currents that are local and typically short term include rip currents, longshore currents, and tidal currents. Ocean currents are created by wind, water temperature, salt content, and the gravity of the moon. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet. The deep current moves toward the equator and warms up, becoming less dense and rising to the surface in “upwellings.”. We can learn on what kind of fish species that has a migration following the ocean current. There are two types of gyres which are the flow clockwise in the Northern Hemisphere oceans and counterclockwise in the Southern Hemisphere. These currents transfer heat from the tropics to the polar regions, influencing local and global climate. The oceans transfer heat by their currents, which take hot water from the equator up to higher latitudes and cold water back down toward the equator. Besides that, the existence of ocean current can help the life cycle of some species of fish that usually move to one place to another places to breed. Oceanic currents are driven by several factors. The 5 Effects of Climate Change on Marine... How Climate Change Affect The Color of Sea... How Global Warming Damage The Coral Reefs. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet. The ocean water in the equator areas will be hotter compare to the ocean water in the polar region. There will be more interesting article that you should not be missed! These currents move because of solar heating and … They are - waves, tides and ocean currents. 5.1k plays . MHRD NME-ICT  Deep water currents are another category of ocean currents. Studying about the ocean current also help us to know the fishing route. And or by another words we would like to use ocean current as a natural mover for ship will be more beneficial for us. Which type of ocean movement is a large-scale pattern that can circulate across all the oceans? Instead of airflow, these currents primarily arise from variations in the density of seawater, controlled by its temperature and salt content (salinity). Ocean current is also important for the last of many living beings. Math. Well, you might have heard so many names like Kuroshio current, Oyashio current, Peru current etc. Distribution of ocean currents; Causes of ocean currents. Ocean currents are patterns of water movement and patterns that influence climate zones and weather patterns around the world. Currents also affect people in other ways, though. The condition will be different if there is no rock inside the hose, the water will flow better without the existence of the rock inside it. Some ocean currents flow at the surface; others flow deep within water. Tides create a current in the oceans, near the shore, and in bays and estuaries along the coast. Some currents flow for short distances; others cross entire ocean basins and even circle the globe. They’re primarily driven by winds and by seawater density, although many other factors – including the shape and configuration of the ocean basin they flow through – influence them. While ocean currents themselves can have flow rates of hundreds or thousands of Sv per second, the total Sv flow for all the freshwater sources in the world is only equal to about 1 Sv: a demonstration of the massive scale of ocean currents compared to the flow of rivers. When the movement of deep ocean current is upwelling this means that the cold water from the bottom of the ocean is going up to the surface. © DeepOceanFacts.com -All Right Reserved. Tidal currents are the only type of current affected by the interactions of the Earth, sun, and moon. It can bring 4500 times more water compare to the amount of water in the Mississippi River. The wind cause the ocean current track shift about 45 degree to the right or left from the normal wind direction.
