Sentences with phrase «volumes of ice on»

The buttresses of ice frozen around Antarctica's edges, hundreds of meters thick in many cases, are also in the sea, but they can act like doorstops and — once moved out of the way — can allow huge volumes of ice on the continent (in theory) to move toward the sea more easily.

Writing in Nature Climate Change, two scientists from the Potsdam Institute for Climate Impact Research (PIK) say the melting of quite a small volume of ice on the East Antarctic shore could ultimately trigger a discharge of ice into the ocean which would result in unstoppable sea - level rise for thousands of years ahead.

The entire structure loses mechanical strength despite the fact that only a tiny volume of ice on the surface changes temperature and thus its mechanical properties.

This requires no such nerve - wracking processes; it is literally as easy as boiling water for the first hour or so, and then you'll keep an eye on it and stir it regularly until it is just a slip of its original volume, intense magnification of the original taste, and oh so gooey on a crepe (filled with fresh banana and mango, here), on ice cream or on a spoon.

So, what tourism is impacting and actually what climate change is impacting is a relatively very small piece of that peninsula; but you know the impact on the peninsula if all that ice melts could be huge; when they talk about sea levels rising, you know, by inches and feet, you know if that ice along the peninsula melts they will add to the volume of the sea very quickly.

The melting of a rather small ice volume on East Antarctica's shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea - level rise for thousands of years to come.

What is alarming is that the volume of water and the extent and rapidity of its movement is suprisingly much greater than previously believed, and that a possible, perhaps likely, effect of this on ice sheet dynamics is to make the ice sheets less stable and more likely to respond more quickly to global warming than previously expected.

On November 16, 2011, scientists announced that data from NASA's Galileo probe (which operated from 1989 to 2003) appear to reveal at least two bodies of liquid water the volume of the North America's Great Lakes underneath the surface ice of Europa.

«Eventually we'll move to a business of lower priced [NOOK] at higher volume» he explained, as well as confirming that plans to sell off the NOOK division — which Microsoft was tipped to be interested in buying at one point — had been put on ice for the moment, while the segment recovers.

- a lot of focus was put on sound effects in order to immerse players in the world of Hyrule - the development team worked with Sound Racer, a studio specialized in sound effects - this studio also worked on Xenoblade Chronicles X - they recorded more than 10 000 different sounds for the game - the team used a school bag to simulate the sound of rubbing leather - for the sound of «normal» footsteps, they mixed various kinds of sands - for the sounds of equipment, they had to search for various materials and find ways to use them - they used an actual block of ice to recreate the sound of footsteps on ice - with the ice block, it always ended up melting, or getting cracks when the staff had to walk on it - Link's footsteps were made by a woman - depending on Link's actions and the equipment he's using / wearing, the recorded sounds were separated out individually - the volume is changed as needed to make a particular sound stand out - check out sound effect samples here

However recently I've found myself wavering on the issue of how fast we'll see a transition to a virtually sea ice free state (less than 1M km ^ 2 off the Canadian Arctic Archipelago and the north of Greenland) and it's because of the PIOMAS volume results.

So unless the perimeter of the Greenland ice sheet is the exact same thickness as the entire ice sheet (say 3 km on average), an area loss there, of 15 %, will produce a much smaller % volume loss, than say if this area loss were smack dab in the middle of the Greenland ice sheet.

Based on their choice of time - shift rather than volume shift to «correct» the models, I'd suspect that an assumption of lingering ice is built into the models.

The volume of grounded ice on Earth is 2.934 x 10 ^ 16 m ^ 3.

42 Eric, data on the volume of ice and potential sea level rise (pslr) associated with the various components are given in a table on this page:

Since the volume of ice at risk under BAU is within a factor of two of the volume of ice at risk during a deglaciation under orbital forcing, while the forcing is much more rapidly applied under BAU, looking at sea level rise rates in the paleo - record might actually be considered a search for lower limits on what to expect if reticence did not run so strongly in our approach.

To establish this uncertainty in the ice - volume record (Schweiger et al. 2011), we spent a significant effort drawing on most types of available observations of ice thickness thanks to a convenient compilation of ice thickness data (Lindsay, 2010).

Given that thin ice — as you explained — boosts heat transfer from ocean to air, is a focus on ice volume as an indicator of the «health» of the system (for lack of a better word) a distraction?

Volume gives us an idea on how much freshwater is stored in Arctic sea ice — an important element in the global - Arctic hydrological cycle, i.e., the cycle of distillation due to freezing, and subsequent export, and melt.

Another possibility might be a slowing of deep circulation (not sure how much there is, mind), in which case the opposite occurs, and the surface waters heat up even faster, leading to yet more rapid surface melt, smaller winter ice volumes and so on.

Wili: As ice volume decreases, the fraction of volume which is new ice increases, and hence the year to year variability in new ice becomes a larger fraction of the total ice volume variability, so I don't think the smoothed downward slope will stay as smooth, i.e. you should expect bigger surprises to the upside on a given winter if it is cold and has heavy snow fall.

At face value their numbers suggest the Arctic will be left with an extensive cover (> 4 million km ^ 2) of ice but only a small volume (< 2 million km ^ 3): i.e. on average the ice will be less than half a metre thick.

If you're not refuting the volume analysis, then I can't see how you can say focusing on ice volume is «a bit funky» — it's clearly a more important measure of the system's ability to recover, which is the central point of this post.

«Preliminary data also indicate 2008 may represent the lowest volume of Arctic sea ice on record, according to the researchers.

Thus, both CO2 and ice volume should lag temperature somewhat, depending on the characteristic response times of these different components of the climate system.

On decadal and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the volume of water in the global ocean: i) thermal expansion (Section 5.5.3), and ii) the exchange of water between oceans and other reservoirs (glaciers and ice caps, ice sheets, other land water reservoirs - including through anthropogenic change in land hydrology, and the atmosphere; Section 5.5.5).

To better understand the difference between measuring ice volume and mass, Simons compares it to a person weighing himself by only looking in the mirror instead of standing on a scale.

Glacial periods give way to interglacials on some occasions when the Northern Hemisphere's summer solar insolation (the amount of solar radiation received by Earth's surface) increases alongside corresponding decreases in ice volume and increases in temperature and atmospheric carbon dioxide (CO2).

There has been a lot of discussion over the past few years on the use of sea ice volume as a better index than sea ice extent for use in Outlooks.

In summary the melting of land ice floating on the ocean will introduce a volume of water greater than that of the originally displaced sea water, hence raising the water level a little.

In that case it is important to have a more precise statement, so I went back to check the reference Journal of Marine Systems Volume 48, Issues 1 - 4, July 2004, Pages 133 - 157 Sea ice from the Kara Sea region reaches Fram Strait from 2 to 4 years (min 2 years) on average, and while sea ice from the Laptev Sea takes roughly 4 — 6 years (min 3 years) to reach Fram Strait»... from the East Siberian, Chukchi and Beaufort seas within 6 — 10 years.

Measuring the distance apart and speed of 2 satellites in space orbiting the earth to the width of a human hair with no margin for error [damn those drift recalculations], and taking into account unknown factors with respect to the true values for water depth, water weight at different salt concentrations, ice depth magma flows, volcanic activity etc [ie making a lot of guesses], plus taking human motivation on board [like CO2 increase must melt ice surely] can give you an accurate measurement of the volume ice in Antarctica.
