Sentences with phrase «large gyres»

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]

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.

SeaWiFS data show that photosynthesizing organisms have declined in certain ocean gyres (large - scale surface current patterns), said Jim Yoder, a scientist at the Woods Hole Oceanographic Institution, in a NASA article commemorating the end of SeaWiFS's mission.

Such accumulation zones are created when large amounts of floating plastic debris are caught by ocean currents and concentrate in the centre of gyre systems.

Astronomers believed this gyre was altering the jet stream's course, much in the same way a large rock would change a nearby river's path.

A team of researchers with 5 Gyres Institute, a non-profit California - based environmental activist group, collected samples from lakes Erie, Superior and Huron last summer and found large quantities of round, plastic pellets.

The gyre has actually given birth to two large masses of ever - accumulating trash, known as the Western and Eastern Pacific Garbage Patches, sometimes collectively called the Great Pacific Garbage Patch.

Due to its lack of large fish and gentle breezes, fishermen and sailors rarely travel through the gyre.

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.

Thus this isobar gradient is able to have a far larger impact on the total transport through the broad eastern side of the gyre than it is on the very narrow western side of the gyre.

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.).

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

Make a large - scale launch (size determined by previous year's learnings and continued climate modeling) of reflective materials in the Fram Strait or Beaufort Gyre.

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

The outgoing flow through Fram Strait carries with it large volumes of fresh water as fragmented pack ice, a flow that is strongly episodic at decadal scale and is associated with the series of so called Great Salinity Anomalies observed within the circulation of the subarctic gyre and in the Nordic seas that were discussed in the previous chapter.

A large Beaufort Gyre which covers most of the Arctic Ocean during the 1980s, and a transpolar drift stream shifted towards the Eurasian Arctic.

The largest of these patches, approximately as large as Texas, is located in the Northern Pacific Ocean, named the Pacific Gyre or The Great Garbage Patch.

Waters moving in the western boundary currents adjacent to the major gyres (North and South Pacific and Atlantic basins and the Indian basin) transport large quantities of heat poleward from the tropics.

The westerlies of middle latitudes and the trade winds of the tropics drive the most prominent features of ocean surface motion, large - scale roughly circular current systems elongated in the east - west direction known as gyres.

A large part of our crew including the founders of 5 Gyres - Anna Cummins and Marcus Eriksen - filmmakers Friedemann Hottenbacher and Bill Bowles, and musicians Ben Lear and Charlie Bradford (above, on the bagpipes), hiked a mountain in the Juan Fernandez national park, a natural reserve that surrounds the island.

The gyre has actually given birth to two large masses of ever - accumulating trash, known as the Western and Eastern Pacific Garbage Patches, sometimes collectively called the Great Pacific Garbage Patch.

In this paper, it is shown that coherent large - scale low - frequency variabilities in the North Atlantic Ocean — that is, the variations of thermohaline circulation, deep western boundary current, northern recirculation gyre, and Gulf Stream path — are associated with high - latitude oceanic Great Salinity Anomaly events.
