Sentences with phrase «circumpolar deep current»

Third, as first observed in the 1990s, the area is vulnerable to a regional ocean current, ushered in by the shape of the sea floor and the proximity of the circumpolar deep current.

Antarctica's strong Circumpolar Deep Current circles the entire continent, driven by strong winds called westerlies, which also create the Southern Ocean's dangerous and choppy waters.

Not exact matches

The seafloor animals of the Southern Ocean shelf have long been isolated by the deep ocean surrounding Antarctica and the Antarctic Circumpolar Current, with little scope for southward migration.

Around the Antarctic Peninsula, changes in ocean currents, and in particular, changes in circumpolar deep water flowing onto the continental shelf, is melting ice shelves from below.

It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Currdeep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar CurrDeep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Current.

While part of the tidal energy is dissipated on the coasts, another part turns into the circumpolar current and is ultimitely dissipated on the ocean floor, and that current could be reduced or eliminated if the Strait of Magellan froze deep, reducing the rate of deceleration and allowing the core to catch up a little (in its deceleration).

The clues found in sediments deposited during the late Holocene suggest that an ocean current that circles the southern polar region, known as Circumpolar Deep Water, flowed underneath the Cosgrove Ice Shelf and melted it.

The ocean waters of the deep circumpolar current that swirl around the continent have been getting measurably warmer and nearer the ocean surface over the last 40 years, [continue reading...]

The effects of this marked shift in westerly winds are already being seen today, triggering warm and salty water to be drawn up from the deep ocean, melting large sections of the Antarctic ice sheet with unknown consequences for future sea level rise while the ability of the Antarctic Circumpolar Current to soak up heat and carbon from the atmosphere remains deeply uncertain.
