Sentences with phrase «melted ice drifts»

What's more, a recent study in the Journal of Geophysical Letters found that IPCC models had low - balled the rate at which melted ice drifts off, further accelerating the collapse.

Not exact matches

Since there are many techniques to measure the MPP, we can keep using its drift to gauge the extent of ice - sheet melting — even in between the end of the ageing GRACE mission and the launch of the next generation of gravity - measuring satellites, says Chen.

Along the floe's drift course southwards from the Pole, we could see in detail at what point the ice began melting.

Climate change is causing the North Pole's location to drift, owing to subtle changes in Earth's rotation that result from the melting of glaciers and ice sheets.

Since the MPP can be accurately measured using multiple independent techniques, its position and drift can be used to gauge the extent of ice sheet melting, especially in between the end of the ageing GRACE mission and the launch of the next generation of gravity - field - measuring satellites, says Chen.

Further melting could cause more multiyear ice from the Arctic Ocean to drift into the NWP, making it less, not more passable.

Huge, drifting ice rafts (the white spot on the satellite image below) shed minerals as they melt, painting trails of nutrients, teeming phytoplankton, and chlorophyll across hundreds of kilometers of ocean.

Climate change is causing the North Pole's location to drift, owing to subtle changes in Earth's rotation that result from the melting of glaciers and ice sheets.

Chapman also says part of the reason for the large ice loss in 2007 was strong winds from Siberia, which affect both ice formation and drift, forcing ice into warmer waters where it melts.

In an effort to better understand the drastic ice melt happening in the Arctic, Germany is sending a boat to drift with the ice for more than a year as part of the International Arctic Drift Expedidrift with the ice for more than a year as part of the International Arctic Drift ExpediDrift Expedition.

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.

Global warming appears to be shifting the drifting direction of the North Pole so far this century due to the melting of polar ice and redistribution of water on land.

Since the rate of change at the beginning of refreezing tends to be faster than end of melting, removing higher frequencies with a filter introduces a general drift to a earlier date of minimum ice extent.

Update: Since the rate of change at the beginning of refreezing tends to be faster than end of melting, removing higher frequencies with a filter introduces a general drift to a earlier date of minimum ice extent.

Field observations and a drifting buoy tracking through the region also reveal that widespread refreezing of surface ice meltwater as it comes into contact with colder, more saline seawater, has added ice layers to the bottom of floes, slowing down thinning and melt of the ice cover.

Buoys provide key observations for mapping and attributing summer ice loss: drift, bottom vs. top melt, amount of snow accumulation, nature of ponds (even if anecdotal from web cams), and thickness of level ice.

Rapid ice drift is an important factor in regional ice conditions, especially redistribution of multiyear ice into areas with high melt rates at low latitudes.

Continued melt and / or strong northerly winds are required for a change in conditions; drift of multi-year ice from the Lincoln Sea through Nares Strait is expected by the end of the month.

Therefore at least some of any early ice and snow melt in the NH must be due to AGW, yet in justifying his theory he wants to count it all as a consequence of seasonal drift in insolation.

Only a detailed analysis of buoy data and field observations will help resolve this question, but an ice mass balance buoy placed on 1.4 meter thick first - year ice north of Barrow in April has managed to survive into the late melt season, drifting 1,000 kilometers to the North over the course of the summer.

Smoke from the fires is lofting high into the atmosphere, and is drifting toward the Arctic, where soot can hasten the melting of snow and sea ice.

Arctic Currents Weaken or Stop With Double CO2 Levels What they found was that under a business as usual scenario, with CO2 levels doubling by 2070, the Transpolar Drift stops and other Arctic currents weaken due to, among other factors, melting of sea ice and changed wind patterns in a warmer world.

It's true, of course, that the Transpolar Drift tends to accumulate ice in the area we've been discussing, but that hardly means that it is going to slow the overall melt any.

Popular belief has it that the melting of drifting icebergs and floating ice shelves has no effect on the height of the surrounding sea level just like melting... Read more
