Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.

However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water.

Water vapor and clouds are the major contributors to Earth’s greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet’s temperature ultimately depends on the atmospheric level of carbon dioxide.

The Bosporus Strait connects it to the small Sea of Marmara which in turn is connected to the Aegean Sea via the Strait of the Dardanelles. To the north, the Black Sea is connected to the Sea of Azov by the Kerch Strait….

The U.S. Navy routinely operates in the Black Sea consistent with international law, including the Montreux Convention. Ross is one of four U.S. Navy destroyers based in Rota, Spain, and assigned to Commander, Task Force 65 in support of NATO’s Integrated Air Missile Defense architecture.

The Republic of Crimea is a federal subject (republic) of Russia located on the disputed Crimean Peninsula, which was annexed by Russia from Ukraine in 2014, but is still internationally recognized as being part of Ukraine.

As temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Terms in this set (25) temperature and salinity changes at surface cause high-density water to form, which sinks. Dense water spreads beneath the surface, causing deep currents. These currents have vertical motion.

Two major kinds of currents define the planet’s oceans: surface currents driven by wind and deep-water currents driven by variations in seawater density.

There are five major gyres: the North Atlantic, the South Atlantic, the North Pacific, the South Pacific and the Indian Ocean Gyre, see figure 1. The Antarctic Circumpolar Current is situated in the Southern Ocean and constantly circles around Antarctica because there are no land masses to interrupt the currents.

There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.

Currents, The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current.

There are two types of currents, surface currents and deep water currents, that dictate how and where water will move. Scientists study currents to learn more about how the ocean works mechanically, as well as using the speed and location of currents as a way to measure changes in large bodies of water.

There are many types of currents such as those driven by salinity, wind, temperature or the Coriolis effect. Two of the most commonly identified are surface currents and deep ocean currents. Surface currents are driven by winds, are fast and make up 10% of the world’s oceans.

The Gulf Stream

The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.

Waves are created by the wind and then radiate in all directions away from the disturbance. Currents represent the movement of water particles which is controlled by winds and density differences. Waves and currents can travel in opposite directions.

Answer: The Gulf Stream determines climate change. Thermohaline circulation occurs due to the difference in the temperatures, densities, and salinities of the waters, and determines climate changes.

List of Ocean Currents of the World

b) Major currents of the North Atlantic Ocean are: Gulf Stream (warm), North Atlantic Drift (warm) and Canary Current (cold). c) Major currents of South Atlantic Ocean are: Benguela Current (cold) and Brazil Current (warm).

The ocean currents known since antiquity are called surface currents. The majority of the ocean’s currents take the form of a temperature- and salinity-driven “conveyor belt” that slowly churns water within the abyssal depths. These loops of water circulation are called deep currents.

Gulf Stream

The surface waters of the Kuroshio Current are warm and salty. This is because the Kuroshio starts in the tropics where the westward flowing North Equatorial Current reaches the western boundary of the North Pacific.

As it is a cold current, except at times of the phenomenon known as El Niño (q.v.), the Peru Current brings fog to the nearby coast but also helps to keep the coast one of the most intensely arid areas in the world.

The water along the coast of California is cold for a couple of reasons. First, the California Current brings cold water from Alaska southward along the coast. And second, cold water from the deep ocean comes up to the surface through a process called upwelling. The water from the deep ocean is full of nutrients.

The California Current is a cold water Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur.

The ocean off of California is actually quite cold, because of the California Current carrying cold water from British Columbia south to southern California. Summertime sea surface temperature is appreciably warmer (maybe a few degrees Celsius), though the water still certainly feels cold.

The California Current is what scientists call an eastern boundary current. Strong current systems flow along the east side (or boundary) of all of Earth’s major ocean basins. They tend to move water toward the equator, and they are prone to strong upwelling.

Question: Can you tell us what the speeds are that correspond to the California Current ? Schwartzlose: The average speed of the general California Current is about 4 to 4 knot (12.5-25 cm/sec) .

The California Current’s surface velocity is commonly less than 10 in. (25 cm) per second, transporting about cu ft (cu m) of water per second above 3,300 ft (1,000 m). The temperature and salinity of its waters vary with seasonal variations in upwelling, insolation, and flow.

The California Current moves less water than the Gulf Stream does. But the California Current has a big effect on the climate of the West Coast of the United States. Usually, the climate along the West Coast is cooler than the climate of inland areas at the same latitude and elevation.

The California current is the eastern boundary current of the North Pacific Gyre, running southward from British Columbia, Canada to Baja California, Mexico. This current draws cool, nutrient rich waters from the Alaska current down along the western coast of North America.

That is true because ocean waters rotate in clockwise fashion. This means Atlantic waters travel to the U.S. East Coast from the south and are relatively warm compared with West Coast Pacific waters that arrive from the north out of the chilly Gulf of Alaska.

The ocean currents on the West coast flow North to South. The Pacific is very deep just off shore. The wind blows over this cooler water, making you feel cooler. The wind blows over this warmer water and feels much warmer.
