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 ocea

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.
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.
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.
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).

Although the main focus of the 5

in the world's
oceans (finding out what's the distribution and concentration of plastics
in the sea),
in their trawls the scientists extract samples of lantern fish.

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

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

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.

The demonstration vessel seen below is our «Proof of Concept» boat that has shown we can harvest plastic and other waste from the 5 garbage
Gyres in the Atlantic, Indian and Pacific
Oceans and (via third parties) recycle that waste into clean diesel fuel for shipping and new plastic products.
The 5

in the world's

in the Great Lakes, where they found as many as 466,000 microplastics per square kilometer.
