Sentences with phrase «ocean gyres where»

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.

As may be expected from the positions of ocean currents, most mixing in the upper layers of the ocean takes place on the western boundaries of ocean gyres where the current speeds are greatest.

In 2010 she hitchhiked across the Pacific Ocean on freighter ships to the United States, where she worked with the 5 Gyres Institute in California on the first ever comprehensive study of plastic in the world's oceans.

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.

Researchers at the Algalita Marine Research Foundation documented an increase in plastic debris in the Central Pacific Gyre five-fold between 1997 and 2007, where the baseline in 1997 showed plastic pieces outnumbered plankton on the ocean surface 6:1.4 Photo courtesy NOAA.

Each year enough is thrown away to circle the earth 4 times, with some 10 - 20 million tons reaching the ocean where it harms sea life, kills birds and contributes to the famous plastic gyre.

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.

The 5 Gyres Institute, a leading research organization focusing on plastic pollution in the world's oceans, recently discovered microbeads on a research expedition in the Great Lakes, where they found as many as 466,000 microplastics per square kilometer.

It's a region of the North Pacific ocean where the northern jet stream and the southern trade winds, moving opposite directions, create a vast, gently circling region of water called the North Pacific Gyre — and at its center, there are tons of plastic garbage.

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.

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

Some of the warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade wocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade wOcean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade winds.

On the other hand, during the negative phase of the AO (Arctic Oscillation), water motion in the Arctic Ocean is anticyclonic and the Beaufort gyre is strengthened, so that ice is retained and thickened both in the Canada Basin and along the Siberian coastline, where it may survive summer melting.

Growing where the currents of the ocean meet in a spinning swirl, the Pacific Gyre Garbage Patch is a soup of trash that has floated from all corners of the globe.
