Sentences with phrase «coldest abyssal»

Researchers at the University of Southampton have captured unprecedented data about some of the coldest abyssal ocean waters on earth — known as Antarctic Bottom Water (AABW)-- during first voyage of the yellow robotic submersible known as Boaty McBoatface, which arrived back in the UK last week.

The much slower thermohaline circulation mixes cold abyssal water on a time scale of centuries — the global ocean turnover time estimated from bottom current velocities is estimated to be on the order of half a millennium

The warmth is eventually diluted into the frigid (3C) abyss by a factor of 10 to 1 (the ratio of cold abyssal water to warm surface water).

Not exact matches

Along one string of sites, or «stations,» that stretches from Antarctica to the southern Indian Ocean, researchers have tracked the conditions of AABW — a layer of profoundly cold water less than 0 °C (it stays liquid because of its salt content, or salinity) that moves through the abyssal ocean, mixing with warmer waters as it circulates around the globe in the Southern Ocean and northward into all three of the major ocean basins.

It travelled back and forth through an abyssal current of Antarctic Bottom Water along the Orkney Passage, sometimes in water colder than 0 °C and in currents up to 1 knot, while measuring the intensity of the turbulence.

The key deep - sea habitats are the abyssal plains, hydrothermal vents and cold seeps, cold - water corals, seamounts (underwater mountains) and the deep - water column.

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 Current.

They've used aerosols that only operate for selective time periods, «missing» heat that has magically disappeared into the abyssal oceans without showing itself on the way down, melting Arctic ice that makes places colder because it was so hot.
