Sentences with phrase «polar waters became»

They based their findings on analysis of the chemical isotopes locked in ancient ice from the Weddell Sea embayment, and the evidence suggests that in the past, when polar waters became more stratified, the ice sheets melted much more quickly.

Not exact matches

Cold, polar waters constantly absorb CO2, sink as it becomes more dense, and is transported to the equatorial waters via the ThermoHaline and outgases in the warmer waters of the Indian and Pacific Oceans.

Dan H.: «Cold, polar waters constantly absorb CO2, sink as it becomes more dense, and is transported to the equatorial waters via the ThermoHaline and outgases in the warmer waters of the Indian and Pacific Oceans.»

The way humans mistreat water has dominated headlines and become mission critical to address: the melting polar ice caps and rising sea levels, the poisoned tap water in Flint, Michigan — and the threat the Dakota Access Pipeline poses to the Standing Rock Sioux tribe.

The polar bears which inhabit the region have become a Churchill icon, but Beluga whales are also a common sight in Churchill's waters and the area is also world - renowned amongst ornithologists for its diverse and often rare birdlife.

Also... Not discussed in the article... As polar ice becomes greatly reduced, oceans will likely warm much more rapidly (similar to what happens when ice in a glass of water becomes minimal).

Unfortunately, North Atlantic polar and subpolar waters that now offer hospitable refuge down to depths of 3 km will become mostly corrosive by the end of the century due to invasion of fossil fuel CO2.

This new study has demonstrated that cold polar surface waters will start to become corrosive to these calcifying organisms once the atmospheric CO2 level reaches about 600 parts per million, which is 60 % more than the current level but which could be attained by the middle of this century.

Model simulations indicate that polar surface waters will become undersaturated for aragonite in the near future for the Arctic (atmospheric carbon dioxide of 400 - 450 ppm) and by mid-century for the southern ocean off the Antarctic (atmospheric carbon dioxide of 550 - 600 ppm).

This becomes silly because, evidently, the warmer deep ocean water is not too cold to provide warming in a polar winter, an environment that doesn't just cool water down, it freezes it solid.

And in the Southern Ocean surrounding Antarctica an ominous bulge of water near the southern polar zone became an indicator of an increasing rate of melt from some of the largest glaciers on Earth.

As the Earth's surface cools further, cold conditions spread to lower latitudes but polar surface water and the deep ocean can not become much colder, and thus the benthic foraminifera record a temperature change smaller than the global average surface temperature change [43].

I'm not sure whether this is off topic, but I have read in other threads that there is less cold water plunging to the ocean floor around Antarctica (and presumably the Arctic too) due to the sea water becoming less saline due to increased precipitation and melting polar ice.
