Sentences with phrase «gyre systems»

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.

These responses are appropriate for keeping young turtles within the gyre system and facilitating movement along the migratory route.»

Not exact matches

The scientists then plopped them — the biggest, seven inches long — off the coast of Florida and into the Gulf Stream, which is part of the North Atlantic Gyre, a system of currents that flows clockwise up the U.S. East Coast.

On track, for these turtles, means following a warm, food - rich current system known as the North Atlantic gyre.

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.

Conceptually, it's hard to see how the Gulf Stream western boundary current could be weakened by conditions around Greenland; this is a fluid dynamics system, not a mechanical «belt»; a backup due to less deep water formation should have little effect on the physics of the gyre and the formation of the western boundary current, and it also seems the tropical warming and the resulting equator - to - pole heat transport are the drivers — but perhaps modulation by jet stream meandering is playing some role in the cooling?

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.

According to the Five Gyres Institute, these tiny plastic beads, used in face & body scrubs and toothpaste, are washed directly down the drain and into our water systems, where they harm our waterways and the animals that live there.

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.

Because gyres are systems of circulating currents, they result in marine debris accumulation at their centers.

For example, the Beaufort High — an extension of the Siberian High system — is a pressure system that drives the anticyclonic motion of the Beaufort Gyre.

This spins up sub-polar gyres pushing cold water into the Californian and Peruvian Currents — diluting warm surface water and biasing the system to more upwelling.

Tracing freshwater anomalies through the air - land - ocean system: A case study from the Mackenzie River Basin and the Beaufort Gyre.

Rawlins, M. A., M. Steele, M. C. Serreze, C. J. Vorosmarty, W. Ermold, R. B. Lammers, K. C. McDonald, T. M. Pavelsky, A. Shilomanov, and J. Zhang, «Tracing freshwater anomalies through the air - land - ocean system: A case study from the Mackenzie River Basin and the Beaufort Gyre», Atmos.

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.

Zhao B., T. Reichler, C. Strong and C. Penland (September 2017): Simultaneous Evolution of Gyre and Atlantic Meridional Overturning Circulation Anomalies as an Eigenmode of the North Atlantic System.

Computer models have shown the slowing and speeding up of the subpolar gyre can influence the entire ocean circulation system.»

We find that the energy transport associated with wind - driven ocean gyres is closely coupled to the energy transport of the midlatitude atmosphere so that, for example, the heat transport of both systems scales in approximately the same way with the meridional temperature gradient in midlatitudes.
