Sentences with phrase «crack in the ice shelf»

If you zoom in far enough, you'll be able to see the huge crack in the ice shelf.

Or the news from Antarctica this past May, when a crack in an ice shelf grew 11 miles in six days, then kept going; the break now has just three miles to go — by the time you read this, it may already have met the open water, where it will drop into the sea one of the biggest icebergs ever, a process known poetically as «calving.»

First, a new crack in the ice shelf developed near the center of the glacier the last 12 months.

Not exact matches

More than once we had lost one of our four engines, and in 1987 a giant crack became persistently visible along the edge of the Larsen B ice shelf, off the Antarctic Peninsula — making it abundantly clear that an emergency landing would be no gentle touchdown.

In 2014, a crack that had been slowly growing into the ice shelf for decades suddenly started to spread northwards, creating the nascent iceberg.

The crack remained dormant for decades, stuck in a section of the ice shelf called a suture zone, an area where glaciers flowing into the ice shelf come together.

Science Ticker Science News Staff Antarctica's Larsen C ice shelf is within days of completely cracking The crack in Antarctica's Larsen C ice shelf (our No. 3 story for 2017) grew 17 kilometers at the end of May (SN Online: 6/1/17).

BREAK UP Last year a crack stretching tens of kilometers rapidly spread across Larsen C, shown here in 2009, one of the largest ice shelves in Antarctica.

In November 2014, Jansen assembled images of Larsen C taken by NASA's Landsat satellites and noticed something unusual: One of the cracks had spread past the suture zone and was more than halfway toward breaking off a large section of the ice shelf.

A massive crack in Antarctica's fourth - biggest ice shelf has surged forward by at least 10 kilometres since early January.

Large pools of melt water splotching the ice shelf probably forced open cracks in the ice.

But liquid water in the cracks can drill like a hot knife to the base of an ice shelf, snapping it in two.

Recent radar mapping of Antarctica's Larsen C ice shelf (top left) reveal that a new crack (right in both inset and white section of diagram) has forked from a long fissure that cuts across the ice shelf.

Scientists have watched as a crack in the Antarctic Peninsula's Larsen C ice shelf has grown across the shelf, allowing a massive amount of ice to break away.

In hydrofracturing — the process implicated in the infamous break - up of the Larsen B ice shelf in 2002 — rainfall or meltwater that pools on the glacier's surface drains into crackIn hydrofracturing — the process implicated in the infamous break - up of the Larsen B ice shelf in 2002 — rainfall or meltwater that pools on the glacier's surface drains into crackin the infamous break - up of the Larsen B ice shelf in 2002 — rainfall or meltwater that pools on the glacier's surface drains into crackin 2002 — rainfall or meltwater that pools on the glacier's surface drains into cracks.

The FACT is that the ice shelf cracked up in the past, so its present condition is NOT unprecedented.

Numerous processes contribute to this, including the removal of buttressing ice shelves (i.e., ice tongues floating on water but in places anchored on islands or underwater rocks) or the lubrication of the ice sheet base by meltwater trickling down from the surface through cracks.

A huge crack across one of the great ice shelves in Antarctica is continuing to widen, researchers revealed.

Some of this meltwater infiltrated cracks in the ice, slicing through the shelf.

Although only a tiny fraction of the ice shelf melts, the water infiltrates the shelf through small cracks in the ice.

The water flows down into cracks in the ice, its weight forcing the cracks wider until large sections of the shelf shatter with surprising quickness.

Scientists first detected a rift in the glacier in October 2011 during flights for NASA's Operation IceBridge.By July 2013, infrared and radar images indicated that the crack had cut completely across the ice shelf to the southwestern edge.

From the University of Texas at Austin, a press release to tell us the ice shelves in the Antarctic peninsula are losing their grip and cracking a bit.

Like a driver facing a crack in a windshield, scientists have been watching a rift growing across a giant ice shelf in Western Antarctica for years, waiting for the day that it would break.

The shear margins which bind the ice shelves laterally are now heavily rifted they say, resembling cracks in a mirror when observed in satellite images.
