The amount of warm water entering the Irminger Current is particularly limited because the sub-Polar
gyre also shunts the pole - ward transport to the east towards the Barents Sea.
5
Gyres also did a study on compostable plastics, that you can read about here.
And 5
Gyres also has partnerships with the Algalita Foundation and the UN Safe Planet campaign to collaborate in research.

In addition to that, they are
also working with 5
Gyres, to keep a daily report of their position and what they see, such as marine life, trash, birds etc..
Hatun et al.
also used altimeter data (local sea level height measurements from satellite observations) to diagnose the norther oceans
gyre circulation.
Given that the answer to this for atmospheric models is a resounding «NO» (particularly because of sub-grid scale processes which need to be effectively pre-ordained through parameterizations), and given that oceanic circulations have much longer adjustment time scales, yet
also have much more intense small scale (
gyre) circulations than the atmosphere, my instinct is that we are not even close to being able to trust ocean models without long term validation data.
al) suggest radiative loss to space, but they
also include references relating to warming bottom water, deepening tropical
gyre warm bowls, and increased mass loss from the Antarctic and Geenland ice sheets.
I
also have a hard time understanding how the Gulf Stream — the western boundary current of the North Atlantic
gyre — would weaken much under global warming, as it is driven by a physical process,
gyre circulation, amplified by the presence of the coastline: http://oceanmotion.org/html/background/western-boundary-currents.htm
Conceptually, it's hard to see how the Gulf Stream western boundary current could be weakened by conditions around Greenland; this is a fluid dynamics system, not a mechanical «belt»; a backup due to less deep water formation should have little effect on the physics of the
gyre and the formation of the western boundary current, and it
also seems the tropical warming and the resulting equator - to - pole heat transport are the drivers — but perhaps modulation by jet stream meandering is playing some role in the cooling?
Even though these findings suggest that the South Pacific has not escaped the impact of marine plastic pollution, the fact that we're still finding small amounts of this petrol based material and not seeing so much debris floating around is
also indicating that this part of the ocean may be in fact different from others explored by 5
Gyres.
A study called Floating marine debris surface drift: Convergence and accumulation toward the South Pacific subtropical
gyre [PDF]
also suggests that this
gyre is a closed loop, and that the garbage that enters it doesn't leave, which could be the cause of not seeing so much debris floating.
and how about nasa's recent report of the apparent arctic ocean
gyre reversal to clockwise that is underway — that the counterclockwise
gyre of the arctic ocean rotation (since 1989) which apparently
also been largely responsible for centrifigally pushing arctic ice into warmer waters, speeding melting — should now predictably result in increasing amounts of ice due to the centripetal pull of the ice toward the north pole?
However the negative NAO
also implies a spin - down of the subtropical
gyre and therefore a drop in the pole - ward transport of warm tropical waters.
Note that there is
also poleward transport in the shallow currents at the western edge of each subtropical ocean
gyre - known as western boundary currents.
But
also results in changes in the Pacific
gyres and the intensity of upwelling.
In the Arctic, it will be the Beaufort
gyre,
also caused by the rotation of the earth.
In the Atlantic subtropical
gyre circulations
also enhance.
For years, scientists have warned that the world's oceans are becoming a plastic soup, with ocean
gyres where plastic and other debris build up (
also known as «garbage patches») covering a quarter of the earth's surface.
Extratropical ocean influences are
also likely to play a role as changes in the ocean
gyre evolve and heat anomalies are subducted and re-emerge (Deser et al., 1996, 1999, 2003; Gu and Philander, 1997).
The Carolina capes and their seaward shoals, along with the broad shelf (up to 200 km),
also influence Gulf Stream flow and result in retention of water masses and their pelagic larvae in
gyres between the capes.
Our friends at 5
Gyres are

A contraction by 11 % of the seasonally stratified sub-tropical
gyre is
also projected in both hemispheres by 2050 due to climate warming.
