Gulf Stream

Atlantic Gulf StreamGolf StreamGulf-stream
Perhaps the most striking example is the Gulf Stream, which makes northwest Europe much more temperate than any other region at the same latitude. These western boundary currents (of which the Gulf Stream is an example) are a consequence of the rotation of the Earth.
The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.

Climate

An ocean current flows for great distances and together they create the global conveyor belt, which plays a dominant role in determining the climate of many of Earth’s regions.
Other ocean currents redistribute heat between land and water on a more regional scale.

Humboldt Current

HumboldtPeruHumboldt ocean current
Other example is Lima, Peru, where the climate is cooler, being sub-tropical, than the tropical latitudes in which the area is located, due to the effect of the Humboldt Current.
The Humboldt Current, also called the Peru Current, is a cold, low-salinity ocean current that flows north along the western coast of South America.

Boundary current

western boundary currentwestern intensificationEastern boundary current
These western boundary currents (of which the Gulf Stream is an example) are a consequence of the rotation of the Earth.
Boundary currents are ocean currents with dynamics determined by the presence of a coastline, and fall into two distinct categories: western boundary currents and eastern boundary currents.

Thermohaline circulation

meridional overturning circulationconveyor beltthermohaline
An ocean current flows for great distances and together they create the global conveyor belt, which plays a dominant role in determining the climate of many of Earth’s regions.
Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes.

Cabbeling

the Wiktionary entry on cabelling
An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.
Ocean currents are responsible for bringing this warmer, saltier water to higher latitudes, especially on the eastern shores of Northern Hemisphere continents, and on the western shores of Southern Hemisphere continents.

Earth

Earth's surfaceterrestrialworld
An ocean current flows for great distances and together they create the global conveyor belt, which plays a dominant role in determining the climate of many of Earth’s regions.
Ocean currents are also important factors in determining climate, particularly the thermohaline circulation that distributes thermal energy from the equatorial oceans to the polar regions.

Upwelling

Where significant vertical movement of ocean currents is observed, this is known as upwelling and downwelling.
Upwellings that are driven by coastal currents or diverging open ocean have the greatest impact on nutrient-enriched waters and global fishery yields.

Argo (oceanography)

ArgoArgo floatsArgo program
Deep ocean currents are currently being researched using a fleet of underwater robots called Argo.
Argo is an international program that uses profiling floats to observe temperature, salinity, currents, and, recently, bio-optical properties in the Earth's oceans; it has been operational since the early 2000s.

Season

seasonsseasonalfour seasons
In addition, the areas of surface ocean currents move somewhat with the seasons; this is most notable in equatorial currents.
Seasonal weather fluctuations (changes) also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Niño/ENSO and other oceanic cycles, and prevailing winds.

Sverdrup

Svsverdrup (sv)
Ocean currents are measured in sverdrup (sv), where 1 sv is equivalent to a volume flow rate of 1000000 m3 per second.
It is used almost exclusively in oceanography to measure the volumetric rate of transport of ocean currents.

Geostrophic current

A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect.

Plankton

planktonicnanoplanktonmicroplankton
Cold ocean water currents flowing from polar and sub-polar regions bring in a lot of plankton that are crucial to the continued survival of several key sea creature species in marine ecosystems.
While some forms are capable of independent movement and can swim hundreds of meters vertically in a single day (a behavior called diel vertical migration), their horizontal position is primarily determined by the surrounding water movement, and plankton typically flow with ocean currents.

Marine debris

Ocean currents are important in the study of marine debris, and vice versa.
The toys have since been found all over the world, providing a better understanding of ocean currents.
