Sentences with phrase «subtropical ocean gyres»

These two near - surface currents converge in the centre of the subtropical ocean gyres and, with nowhere else to go, the water is directed downward into the ocean interior (known as Ekman pumping).

Stronger easterly trade and midlatitude westerly winds spin up the subtropical ocean gyres.

A near - coherent spin - up of all five subtropical ocean gyres was observed from the early / mid 1990's through to about 2004, when a peak was reached.

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

Most of the deep ocean warming is occurring in the subtropical ocean gyres - vast rotating masses of water in each ocean basin where near - surface currents converge and are forced downward into the ocean interior.

The main mechanism for wind - driven mixing into the deep ocean (down to around 2000 metres) is via convergence of warm tropical surface water in the subtropical ocean gyres.

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

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.

Moreover, the few existing community - level studies were mostly conducted in rather eutrophic environments, while less attention has been paid to oligotrophic systems such as the subtropical ocean gyres.

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.

Not exact matches

If you trawl a fine mesh net through any of the globe's five subtropical gyres — giant ocean vortexes where currents converge and swirl unhurriedly — you will haul on deck a muddle of brown planktonic goop, the occasional fish, squid or Portuguese man - of - war — and, almost certainly, a generous sprinkling of colourful plastic particles, each no larger than your fingernail.

Their work, published this month in the Proceedings of the National Academy of Sciences, did find millions of pieces of plastic debris floating in five large subtropical gyres in the world's oceans.

The patch is in an area of ocean between California and Hawaii called the North Pacific Subtropical Gyre — a kind of swirling dead end for Pacific currents, which have been depositing floating plastic trash there for decades.

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.

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.

«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.

«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.

An organization whose mission is to «conduct research and communicate about the global impact of plastic pollution in the world's oceans and employ strategies to eliminate the accumulation of plastic pollution in the 5 subtropical gyres» is 5 Ggyres» is 5 GyresGyres.

Two reasons why this should be so in the real world are that, first, the Southern Hemisphere subtropical gyres are situated mostly in the Southern Ocean and South Atlantic, and second, that some of the heat coming into the Pacific Ocean basin doesn't actually stay there.

When the tropical easterly trade winds strengthen, as they have from the year 2000 onwards, this whole wind - driven ocean circulation becomes more vigorous, the South Pacific subtropical gyre spins up, and the western arm of the gyre exports more tropical water through the Indonesian archipelago into the Indian Oocean circulation becomes more vigorous, the South Pacific subtropical gyre spins up, and the western arm of the gyre exports more tropical water through the Indonesian archipelago into the Indian OceanOcean.

This is where the majority of deep ocean warming is occurring in the last decade or so - in the subtropical gyres.

The active wind - driven ocean circulation should have drawn down a lot of extra heat into the ocean via the subtropical gyres.

It has been noted in a five - member multi-model ensemble analysis that, associated with the changes in temperature of the upper ocean in Figure 10.7, the tropical Pacific Ocean heat transport remains nearly constant with increasing greenhouse gases due to the compensation of the subtropical cells and the horizontal gyre variations, even as the subtropical cells change in response to changes in the trade winds (Hazeleger, 2ocean in Figure 10.7, the tropical Pacific Ocean heat transport remains nearly constant with increasing greenhouse gases due to the compensation of the subtropical cells and the horizontal gyre variations, even as the subtropical cells change in response to changes in the trade winds (Hazeleger, 2Ocean heat transport remains nearly constant with increasing greenhouse gases due to the compensation of the subtropical cells and the horizontal gyre variations, even as the subtropical cells change in response to changes in the trade winds (Hazeleger, 2005).

Subtropical gyres are centered near 30 degrees latitude in the North and South Atlantic, the North and South Pacific, and the Indian Ocean.

An intensification of the trades has affected surface ocean currents called the subtropical gyres, and these changes have resulted in a predominance of the La Nina state.
