Sentences with phrase «oceanic gyre»

Ocean currents have been carrying floating debris into all five of the world's major oceanic gyres for decades.

High concentrations of microplastics have been found in five oceanic gyres (the North Atlantic, South Atlantic, South Indian, North Pacific and South Pacific gyres).

Reductions in seafloor POC flux will be most drastic, on a percentage basis, in the oceanic gyres and equatorial upwelling zones, with the northern and southern Pacific Ocean and southern Indian Ocean gyres experiencing as much as a 32 — 40 % decline in POC flux (Tables 2, 3; Figures 2, 3).

Indian Ocean Garbage Patch There are trash vortices in each of the five major oceanic gyres.

The Indian Ocean Garbage Patch on a continuous ocean map centered near the south pole The Indian Ocean garbage patch, discovered in 2010, is a gyre of marine litter suspended in the upper water column of the central Indian Ocean, specifically the Indian Ocean Gyre, one of the five major oceanic gyres.

The area of increased plastic particles is located within the North Pacific Gyre, one of the five major oceanic gyres.

There are trash vortices in each of the five major oceanic gyres.

As with other patches in each of the five oceanic gyres, the plastics in it break down to ever smaller particles, and to constituent polymers.

In both hemisheres cold polar winds and storms pushing into lower latitudes are spinning up the oceanic gyres and increasing deep ocean upwelling in the eastern and central Pacific in the self reinforcing pattern of the Interdecadal Pacific Oscillation.

What happens when the oceanic gyres stumble and fail?

The influence of the polar annular modes on winds and oceanic gyres is shown schematically here.

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).

The AHT and the transport in the oceanic gyres are positively correlated, because the gyre transport responds to the atmospheric winds, so militating against long - term variability involving the wind - driven flow.

Not exact matches

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.

Given that the answer to this for atmospheric models is a resounding «NO» (particularly because of sub-grid scale processes which need to be effectively pre-ordained through parameterizations), and given that oceanic circulations have much longer adjustment time scales, yet also have much more intense small scale (gyre) circulations than the atmosphere, my instinct is that we are not even close to being able to trust ocean models without long term validation data.

Everything ends up in the sea eventually, pretty much, as witness our oceanic «plastic gyres».

The various gyres are examples of modal responses of the oceanic subsystem.
