Sentences with phrase «dense water masses»

These dense water masses spread into the full extent of the ocean and gradually upwell to feed a slow return flow to the sinking regions.

Antarctic Bottom Water, the most voluminous water mass in the oceans, is now being replaced by warmer, less dense water masses as the deep oceans warm.

Not exact matches

It's here in the frigid Nordic Seas that water masses become cold and dense, sinking in streams that snake along the basin bottom, eventually turning southward and reaching the subtropics in about a decade.

But in many instances, the simulations show, even planets starting with rocky cores as little as 1.5 Earth's mass may trap and hold atmospheres containing between 100 and 1000 times the amount of hydrogen found in the water in Earth's oceans — thick, dense envelopes exerting pressures so hellish that life on the planets» surfaces might be almost impossible.

Combined with its mass of 8.57 Earths, that size suggests the planet has a dense rocky core, surrounded by a 3000 - kilometre - thick envelope of nearly pure water.

There is also a contribution of excess atmospheric CO2 absorption introduced to deep - water masses from dense, cold CO2 - rich surface waters at downwelling sites (e.g., North Atlantic), which then move through the oceans via meridional overturning circulation.

The planet's mass and diameter are consistent with the hypothesis that it has a low average density due to an inferred composition of three - fourths water (possibly 47 percent) and other ices (that have subliminated into a «supercritical fluid» above an «electronically conductive,» dense fluid plasma below a steamy atmosphere) and one - fourth rock and iron in the core.

The actual answer is that water has a molecular mass of 18, while dry air has an average molecular mass of 29, so moist air is less dense at the same temperature and pressure.

This research shows that the densest AABWs (observed in 1994) no longer exist, as seen by the core of the region's abyssal water mass located as much as 600 m deeper in the water column in 2016 (illustrated by black curves in panel b).

This project will use an observational program to simultaneously identify the mechanisms responsible for water mass modification within the Terra Nova Bay polynya and document all aspects of dense shelf water formation within an Antarctic polynya system.

Eventually the surface water became denser than the warming deep water and started to sink, causing the corrosive deep water mass to spill over the ridge — overflowing the «giant bath tub».
