«We realised that our buoys are in fact a kind of marine debris,» says Nikolai Maximenko of the University of Hawaii in Honolulu, who collaborated with 5 Gyres researchers to identify which areas of the ocean should have especially high levels of plastic pollution.

The report adds that every square mile of ocean is home to nearly 50,000 pieces of litter, much of which tends to harm or kill wildlife that either ingests the plastic or gets trapped in discarded netting, which is just as common in the Northern Gyre as discarded soda bottles.

Near the simulated north coast of Portugal, most turtles swam south, which would keep them within the gyre.

To find out how the turtles remain within the gyre, Ken Lohmann of the University of North Carolina at Chapel Hill and colleagues made hatchlings swim in the presence of magnetic fields that simulated locations off Portugal, by which the gyre passes.

If read as an ideological tract, The Living Dead at Manchester Morgue could refer to the expanding gyre that separates distinct concepts of «authenticity» — hence the detective story in this ersatz Night of the Living Dead (commissioned to do a straight ripper of the Romero classic — which was completely without a detective figure — Grau inserts an element of Tiresian knowledge) that underscores the futility of investigation into areas that, by their nature, resist clarification.

Or the fish jumping from the sea in Gyre (2014), either inhaling or vomiting the stream of household trash in which it swims.

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.

Thus, the subtropical gyre circulation is a horizontal circulation with poleward mass transport along the western boundary, and equatorward transport everywhere east of that, and providing no net northward mass transport integrated across the basin (which is what Bryden et al have done).

But if you want a very rough idea... (others will no doubt correct me) then the wind - driven circ ends up being a large gyre, which concentrates into a narrow current along the western boundary, with a much broader return in the rest of the basin — William]

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.).

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.

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).

Ultimately if the freshwater melt was a dominant (which seems hard to believe given the scale of the wind - driven gyre transport) factor, it would be entrained into the gyres at the surface and you'd see an overall freshening of North Atlantic surface waters to make the whole system more like the Pacific, which has a much weaker meridional overturning circulation.

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.

Curiously, very little of the ice seems to be moving west along the archipelago, towards the Beaufort sea polynya, which I would expect from the action of the Beaufort Gyre.

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?

Increased winds in the tropics and mid latitudes can «spin up» the mid-ocean gyres, increasing the rate at which water gets pumped down to mid depths through Ekman pumping, taking heat from the surface with it.

Where things get a little mysterious is in the attribution of the warming subsurface to a change in the NA gyre circulation, which is attributed to a switch in the NAO (North Atlantic Oscillation) from a positive to a negative phase.

The strength of the Icelandic Low is the critical factor in determining path of the polar jet stream over the North Atlantic In the winter the IL is located at SW of Greenland (driver Subpolar Gyre), but in the summer the IL is to be found much further north (most likely driver the North Icelandic Jet, formed by complex physical interactions between warm and cold currents), which as graphs show had no major ups or downs.

2) That when it is mechanically forced by your gyres to a lower stratum, which is above water at T3, it displaces the water at that stratum upward, which is at some T2, < T1 but > T3.

These subtropical ocean gyres are large rotating masses of surface water which occupy the mid-latitudes of each ocean basin.

The circulation to the south on the southern rim of the subtropical gyre is completed by the westward - flowing North Equatorial Current, part of which flows into the Gulf of Mexico; the remaining part flows northward as the Antilles Current.

The cool phase starts with upwelling which starts with flows in the Peruvian and Californian Currents spinning up with the Pacific gyres.

This media - friendly statistic emerged in a 2016 report on the «circular economy,» a concept embraced by 5 Gyres in which plastic products are better designed to never become waste, but to be perpetually used or recycled.

In response to your question I would refer you to my comment above Dave Wendt (14:39:39): where I discuss the Rigor and Wallace paper of 2004 which demonstrated that the decline in sea ice age and thickness began with a shift in state in Beaufort Gyre and the TransPolar Drift in 1989 which resulted in multiyear ice declining from over 80 % of the Arctic to 30 % in about one year and that the persistence of that pattern has been responsible for the continuing decline.

Precipitation in the Desert Southwest correlates significantly with solar irradiance lagged 3 and 5 years, which suggests a link with ocean - water temperature anomalies transported by the Equatorial Countercurrent as well as the North Pacific Gyre.

The most significant correlations occur in the Pacific Northwest with a lag time of 4 years, which is approximately equal to the travel time of water within the Pacific Gyre from the western tropical Pacific Ocean to the Gulf of Alaska.

Counter currents and gyres created by bottom features such as the Pourtalès Terrace in the Florida Current and the Charleston Bump in the Gulf Stream help retain the pelagic larvae within the area of the Florida Keys and SAB, respectively, by causing persistent gyres and eddies that spin off the current and retain their pelagic flora and fauna, some of which recruit to benthic and pelagic habitats in the region.

You read it right, a melting season that saw mostly cloudy conditions during the sunniest period of the year (June - July - August) has beaten the 2007 melting season which went astonishingly low after weeks of ceaseless sunshine and a massive Beaufort Gyre, continuously compacting the ice pack, well into September.

That's because while the North Pacific gyre has trash coming from North America, China, Japan and Asia coming to one gyre, the South Pacific has the coast of South America, Polynesia, New Zealand, New Guinea and Australia, which might not be contributing garbage in the same amounts.

«I'm genuinely thrilled to see this being introduced at the national level,» said Anna Cummins, a co-founder of the 5 Gyres Institute, which is dedicated to researching and reducing plastic pollution.

In this trip we're heading to the South Pacific gyre, the least explored of the five subtropical gyres (which are rotating oceanic currents that accumulate garbage).

When a gyre region is added to the channel, vertical diffusion in the gyre exerts some control on the channel stratification even at higher winds, forcing the mass balance into a mixed regime in which both eddy and diffusive effects are important.
