Sentences with phrase «much sea ice forms»

For example, in the southern Weddell Sea so much sea ice forms during the autumn and winter months that the amount of salt released in the process turns the water around and below the 450,000 km2 Filchner - Ronne Ice Shelf into a massive protective sheath.

Not exact matches

Hawkings and his collaborators spent three months in 2012 and 2013 gathering water samples and measuring the flow of water from the 600 - square - kilometer (230 - square - mile) Leverett Glacier and the smaller, 36 - square - kilometer (14 - square - mile) Kiattuut Sermiat Glacier in Greenland as part of a Natural Environment Research Council - funded project to understand how much phosphorus, in various forms, was escaping from the ice sheet over time and draining into the sea.

The land bridge forms during ice ages, when much of the water on the planet becomes part of growing continental glaciers, making the sea level much lower than it is today,» explained Shapiro.

Ice formed during the Ice Age is being given back to the sea in our naturally warmer geological period, and man is making matters worse by pouring so much carbon dioxide into the atmosphere that more heat is being trapped within it.

It was formed as a limestone cave system during the last ice age when sea levels were much lower.

Formed in the limestone substrata, they are officially called «karst - eroded sinkholes» and were created prior to the melting which ended the Great Ice Age, when sea levels were much lower than today.

On the other side of the equation, the albedo for sea - ice is likely to be too large, since the sea - ice begins to melt and form ponds, which have properties much closer to that of open water.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

One of the interesting things looking at sea ice from cryosphere today, is how rare it is now for ice to form in much of the Baltic (last year was the first year in a long time that it got very far south) and other peripheral areas.

Francis, who wasn't involved with either study, is one of the main proponents of an idea that by altering how much heat the ocean lets out, sea ice melt and Arctic warming can also change atmospheric circulation patterns, in particular by making the jet stream form larger peaks, or highs, and troughs, or lows.

This has never happened before because the sea ice never retreated very much in the summer and the water temperature could not rise above zero because of the ice cover... The permafrost is acting as a cap for a very large amount of methane (CH4), which is sitting in the sediments underneath in the form of methane hydrates.

But deep water production by convection may be less, depending on how much NADW is Arctic in origin and how much is simply recirculated Antarctic bottom water (extremely dense water, formed as brine under the sea ice around polynas offshore of Antarctica and sliding down the continental shelf into the depths without much mixing, creates a giant pool of dense water extending all the way up the bottom of the Atlantic to about 60 ° N).

Ice sheets can take centuries to millennia to melt or form, whereas sea ice changes occur much more rapidly (as we're currently seeing in the ArctiIce sheets can take centuries to millennia to melt or form, whereas sea ice changes occur much more rapidly (as we're currently seeing in the Arctiice changes occur much more rapidly (as we're currently seeing in the Arctic).

The existence of the glaciers would lower the average temperature of the Earth by reflecting back much of the sunlight that fell on them, and slowly sea ice in the Arctic Ocean would form and expand.
