Sentences with phrase «gyre region»

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.

The sea surface temperature (SST) anomalies that define the AMV are characterized by a basin - scale pattern that has the same sign over the whole North Atlantic, with a maximum loading over the subpolar gyre region.

Linlsey said: «I think the Argo data point to the central gyre regions as key to the ocean - atmosphere heat exchange story.»

Not exact matches

The pattern the water circulation forms in that region is called the Indian Ocean Gyre, one of five of the major ocean gyres of the world that scientists have identified so far.

In previously ice - rich areas such as the Beaufort Gyre off the Alaskan coast or the region south of Spitsbergen, the sea ice is considerably thinner now than it normally is during the spring.

There's plastic trash littering «the Bay of Bengal, the Mediterranean Sea, the coast of Indonesia, all five subtropical gyres; coastal regions, enclosed bays, seas and gulfs.»

Here we report that hatchling loggerheads, when exposed to magnetic fields replicating those found in three widely separated oceanic regions, responded by swimming in directions that would, in each case, help keep turtles within the currents of the North Atlantic gyre and facilitate movement along the migratory pathway.

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.

Holland says it is due to a change in the atmospheric circulation resulting in a change in the North Atlantic gyre which then has allowed warmer water into the South Greenland region.

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.

Stronger easterlies in the Pacific spin up the gyres in both hemispheres and Ekman pumping in those regions intensifies, bringing warmer surface waters to depth.

It seems to me that iron fertilization will likely have its greatest impact in oligotrophic regions (e.g., subtropical gyres) which currently provide less than 10 % of world NPP.

White arrows indicate regions of enhanced wind and black arrows indicate areas of enhanced gyre circulation.

Finally, Clement et al. note that the argument for a role for ocean dynamics, namely the AMOC, pertains to a particular region of the subpolar gyre.

Driven by the long - term average winds in the subtropical highs, Ekman transport causes surface waters to move toward the central region of a subtropical gyre.

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.

Stronger downward transport of water mass must be balanced by upwelling somewhere else, and this occurs in regions of divergence (Ekman suction)- along the equatorward travelling arms of the gyres, and along the equator itself.

Substantial biodiversity exists in both pelagic and benthic realms and along coastlines, in a diverse range of ecosystems from highly productive (e.g., upwelling regions) to those with low productivity (e.g., oceanic gyres).

Since phytoplankton form the base of marine food webs, the world's most productive fisheries are located in areas of coastal upwelling that bring cold nutrient rich waters to the surface (especially in the eastern boundary regions of the subtropical gyres); about half the world's total fish catch comes from upwelling zones.

The results shown here document that ocean salinity and hence freshwater are changing on gyre and basin scales, with the near - surface waters in the more evaporative regions increasing in salinity in almost all ocean basins.

The cold water region with very cold coastal waters along the Greenland and Labrador coasts form the western part of the subpolar gyre circulating anticlockwise.
