Sentences with phrase «ice on the surface now»

Not exact matches

Miniaturization is the key: Experiments that once required a room full of lasers, optical elements, and vacuum systems can now fit in a device the size of an ice chest, with the atoms trapped on the surface of a microchip.
In that case, the ice seen on the surface now would once have been buried beneath dust and rock that insulated it from the sun's heat and prevented it from escaping into space.
For now, the second - highest priority mission on NASA's wish list is the Jupiter Europa Orbiter, which would survey the ice - covered moon Europa and the global ocean that seems to lie beneath its frozen surface.
After comparing it with domes on Earth, scientists now believe Ahuna Mons formed when a slushy mix of internal ice and natural antifreeze reached the surface along a duct — just as magma builds volcanoes on our planet.
Scambos's group predicted the final Larsen B collapse using a model that looks at how much meltwater has pooled on the surface of the ice, and he now hopes to apply the model to bigger Antarctic ice shelves.
Now a team of astronomers, led by Tobias Owen of the University of Hawaii, has discovered nitrogen ice on Pluto's surface (International Astronomical Union Circular, No 5532).
Now a weather station, installed on the Larsen C ice shelf in 2015, has revealed that a quarter of surface melting occurs in the winter because of föhn winds, Peter Kuipers Munneke of Utrecht University in the Netherlands told a meeting of the European Geosciences Union in Vienna last week.
Even deeper oceans of 60 to 125 miles (100 to 200 km) are now believed to lie below surface ice on Callisto and Ganymede, which orbit further out from Jupiter.
Now, a new study led by Brown University researchers suggests that there could be much more ice on Mercury's surface than previously thought.
«Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice,» Christopher Russell of the University of California, Los Angeles, and principal investigator for the Dawn mission, said in a statement.
Now it appears an ice analog of these plates exists on the surface of Jupiter's moon Europa.
The water ice counteracts the traditional danger of living above ground by serving as a radiation barrier, offsetting fears of solar exposure that have, until now, projected Martian architecture into a dark underworld — buried beneath a regolithic surface that is believed to contain perchlorates, gypsum and other substances hazardous to human life.Water as a Radiation Shield By taking advantage of water - ice's ability to filter the sun's rays and protect against radiation, ICE HOUSE prioritizes a life above ground and celebrates the human presence on the planetary surface.
Richard B. Alley, an expert on Greenland's ice sheet at Penn State, told me it's still possible that flows of meltwater from surface lakes could start large areas of ice moving seaward, particularly if the melt zones continue to expand inland as they have been doing for years now.
However, there is both theoretical and observational evidence that melting now occurs on the horizontal surfaces of the Kilimanjaro Northern Ice Field, and contributes to ablation [Moelg and Hardy 2004; Thompson et al 2002].
This result would be strongly dependent on the exact dynamic response of the Greenland ice sheet to surface meltwater, which is modeled poorly in todays global models.Yes human influence on the climate is real and we might even now be able to document changes in the behavior of weather phenomena related to disasters (e.g., Emanuel 2005), but we certainly haven't yet seen it in the impact record (i.e., economic losses) of extreme events.
What scientists once thought was a fairly simple linear process — that is, a certain amount at the surface of an ice sheet melts each year, depending on the temperature — is now seen to be much more complicated.
Indeed, as I mentioned back in Germany, the earth is now thought to have become completely covered with ice and snow on some occasions, all of the land and sea surfaces white except for a few hot springs areas such as Iceland.
The High Latitude L2 Sea and Sea Ice Surface Temperature product is now operationally available on EUMETCast and FTP.
Up until now, this kind of surface dynamic has not been documented on the gigantic, and not - so - long - ago - thought - invulnerable East Antarctic ice sheet.
We can make good estimates of global temperature so can estimate planck radiation (on global level), good estimates of albedo from ice extent, reasonable estimates of evaporation and convection from temperature contraints, now try closing that surface budget with GHG.
