Learn about the ocean in motion and how ocean surface currents play a role in navigation, global pollution, and Earth's climate. Many jobs and economies in the U.S. and around the world depend on the fish and shellfish that live in the ocean. Winds associated with a passing storm system can disturb the ocean surface and cause the actual flow of ocean currents locally to deviate temporarily from long-term average patterns. Tides contribute to coastal currents that travel short distances. And the global conveyor belt? These movements are essential in stirring the ocean, delivering oxygen to depth, distributing heat, and bringing nutrients to the surface. The water starts flowing in the same direction as the wind. How do ocean currents transfer heat? Currents are responsible for circulating water throughout the earth's oceans. This lesson will discuss surface ocean currents, deep water ocean currents, and the forces that drive them. Imagine you fill a bathtub with cold water then add hot water at one end. You will not have warm water until it is mixed. What’s a gyre? Oceanic currents are driven by three main factors: 1. These density differences cause the water to move. The cause of such “hypoxic” (lacking oxygen) conditions is usually eutrophication, an increase in chemical nutrients in the water, leading to excessive blooms of … 13 Causes of Ocean Surface Circulation Currents 1. Trade Winds. Trade winds are the winds that blow in the direction from east to west. These winds have strong effect... 2. Westerlies. Westerlies are winds that are similar to the Trade winds. They can also cause ocean water surface to move... 3. ... Ocean currents form in large and small oceans and seas around the world. The four factors that cause ocean currents: (1) Planet rotation, (2) Wind, (3) Density of the water (depends on temperature and salinity), and (4) Gravitation of the moon and earth. The plates grow when the convection currents cause the spreads, but the spread forces the edges of the plates down into the subduction zones where it is melted once more and turned back into magma. While it takes time for the land to heat up, it also takes time for that land to cool in the fall. Photobacteria research is one of many subspecialties of marine microbiology. Ocean Trenches Ocean trenches, by definition, are trenches in the ocean. A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. The earth rotates on its axis from west to east. Similar to a person trying to walk in a straight line across a spinning merry-go-round, winds and ocean waters get deflected from a straight line path as they travel across the … The changes in sea levels and currents is a result, in part, of the melting freshwater. Monsoon season does not end as abruptly as it begins. They carry warm water from the tropics poleward. Tides are really all about gravity, and when we're talking about the daily tides, it's the moon's gravity that's causing them. What’s a gyre? The world's largest ocean gyres Western boundary currents are warm, deep, narrow, and fast-flowing currents that form on the west side of ocean basins due to western intensification. Ocean currents Flashcards - Questions and Answers | Quizlet How does warm water from the tropics causes mild climates in Western Europe? when surface currents meet continents, the currents are deflected and change direction. These ocean currents are on the ocean's … Ocean acidification is currently affecting the entire ocean, including coastal estuaries and waterways. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). NASA missions that very accurately measure the hills and valleys in the ocean and changes in sea level help scientists understand what is happened with ocean currents. … continental deflection. 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. Define the term current. A very small amount of it even originates as interstellar dust. Salinity of ocean water. Ocean currents carry heat around the Earth. Salinity is the amount of salt in the ocean water. Current research boundary currents. This uplifting of the ocean floor occurs when convection currents rise in … 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. A current is defined as water flowing in one direction across some time and distance. Ocean Currents - BrainPOP. What causes the movement of ocean water? Surface ocean currents carry heat from place to place in the Earth system. The heat travels in surface currents to higher latitudes. This rotation causes both the wind and ocean currents to move from east to west. But currents do not simply track the wind. As the Earth turns, a region gets closer to or further from the bulges. Examples include the Gulf Stream, the Agulhas Current, and the Kuroshio. There is, however, a specific type of trench called a deep ocean trench. The Sun warms water at the equator more than it does at the high latitude polar regions. Causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to Earth's hemisphere. Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. Ocean Currents - BrainPOP. Also discover how observations of these currents are crucial in making climate predictions. Where these winds blow in the same direction for long periods of time, large currents develop and transport vast amounts of water over long distances. As the oceans absorb more heat from the atmosphere, sea surface temperature increases and the ocean circulation patterns that transport warm and cold water around the globe change. As Earth rotates, the moon's gravity pulls on different parts of our planet. The denser, saltier water sinks and forms the currents that marine life depends on. This affects regional climates. Earth’s rotation results in the Coriolis effect which also influences ocean currents. Surface current are at the surface, not deep down. Ocean currents affect climate in several different ways: they regulate temperature, help to stabilize atmospheric conditions in land regions and bring nutrients to marine environments. The oceans teem with microorganisms such as bacteria, viruses, and protists. Ocean floor spreading and rising also affects sea level. Surface ocean currents can create eddies, swirling loops of water, as they flow. The oceans directly absorb more than two-thirds of the Sun’s heat, and overall 25 percent of the planet’s global heat budget is transferred through the actions of ocean currents [8]. The direction of these currents can shift so that different areas become warmer or cooler. This next cause is salinity.
