Where the poleward & equatorward currents of this intensified circulation converge — the centre of the gyres — surface water is pumped downwards into the ocean interior in a process known as Ekman pumping.

In an email chat, Yair Rosenthal of Rutgers University and Braddock Linsley of Columbia University, whose related work was explored here in 2013, said the Argo analysis appeared to support their view that giant subtropical gyres are the place where heat carried on currents from the tropics descends into the deeper ocean.

This is to be expected because the spin - up of the wind - driven ocean circulation speeds up the currents (Ekman transport) which carry heat out of the tropics in the near - surface layers toward the subtropical ocean gyres.

It seems to us quite possible that the capacity of the deeper oceans to absorb heat has been seriously underestimated, especially that of the intermediate waters of the subtropical gyres lying below the mixed layer and above the main thermocline.

And I do think there are a number of questions about interpretation of observations, and the details of the climate model experiment (the very large exponentially increasing freshwater fluxes, the low - resolution of the ocean which obscures the potentially important role of wind - driven ocean gyres, etc.).

There was a long standing Anticyclone SW of North American side of pole exacerbating arctic ocean gyre movement, causing more open water there, as it is big open area right now.

Because of ocean currents and winds, a large chunk of the gyre's trash now eventually lands on the shores of the Hawaiian archipelago.

After I read the Hatun et al paper I thought the major point of the paper was that ocean circulation and the subpolar gyre is an important but little understood factor in the THC and more research in the area was needed.

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.

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.

«The fact that we are seeing an expansion of the ocean's least productive areas as the subtropical gyres warm is consistent with our understanding of the impact of global warming,» he said.

Rob Painting: The transport of heat down into the surface to deep ocean occurs via the subtropical ocean gyres.

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).

Which seems to announce the coming of what will possibly be called the South Pacific Garbage Patch: The fifth area of the ocean to present plastic pollution surveyed by 5 Gyres.

Although one may think that's a good thing, it doesn't really mean that the South Pacific is cleaner but that the currents in this part of the ocean create a tighter gyre and thus the garbage may be more concentrated.

Drexel Environmental Science Graduate Student [ANDY REVKIN says: Some of the sea ice on the Arctic Ocean kind of circles in a gyre, like a slow turntable, and much of it is ejected perpetually past Greenland into the North Atlantic by winds and currents.

While it's hard to imagine floating across the Pacific Ocean from California to Hawaii on a raft made of complete junk to raise awareness of all that plastic floating in the middle of the North Pacific Gyre, the truth is that the guys risking life and

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.

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?

«We are already seeing this in the North Atlantic subtropical gyre, and this is some of the first evidence for climate damping the ocean's ability to take up carbon from the atmosphere.»

To get a glimpse of what was going on in the dark, the researchers looked at samples from two subtropical gyres, or systems of rotating ocean currents, in the South Atlantic and North Pacific.

In 2014, international scientists collaborated with 5 Gyres to publish the first Global Estimate of Marine Plastic Pollution, and determined that 5.25 trillion particles of «plastic smog» surface pollution — weighing in at 269,000 tons — pollute our oceans worldwide.
