Sentences with phrase «thicker ice in the region»

«This is the first - ever such survey in the Northwest Passage, and we were surprised to find this much thick ice in the region in late winter, despite the fact that there is more and more open water in recent years during late summer,» says Haas.

This suggests delayed ice retreat due to thicker ice in the region.

Not exact matches

Data reported by NASA's New Horizons New Horizons mission to the Pluto system shows unusual terrain in this region, which features a large deposit of nitrogen ice with a pattern of polygons that are thickest at their centers and dip at their edges.

There are several habitats once thought to be inhospitable to even the world's most adaptable organisms — places like the core of Chile's Atacama Desert, the driest region on Earth; ice sheet plateaus in Greenland that are 10,000 feet thick; and near hydrothermal vents on the ocean floor with temperatures above 750 degrees Fahrenheit, to name a few.

«The upper haze is so optically pretty thick that it is only in the stormy regions where the haze is penetrated by powerful updrafts that you can see evidence for the ammonia ice and the water ice.

Scientists think that in the «heart» region of Pluto (otherwise known as Sputnik Planum), water ice bedrock might be hidden underneath a thick blanket of other ices made of methane, nitrogen and carbon monoxide.

The thick durable sea ice that routinely cloaked much of the Arctic Ocean in colder decades in the 20th century is increasingly relegated to a few clotted places along northern Canada and Greenland, according to the latest satellite analysis of the warming region.

This is what may have contributed in part to lingering ice in this region as a result of thicker first - year ice (due to a more severe winter and higher winter ice growth) as well.

This thicker multiyear ice takes longer to melt back (both because of greater thickness and higher albedo than first - year ice) and so in conjunction with the weather it is responsible for more extensive ice in the late summer in this region.

(Keep in mind that almost all Arctic sea ice researchers add a big caveat when talking of an «ice - free Arctic Ocean,» noting that a big region of thick floes north and west of Greenland will almost surely persist in summers through this century, which is one reason some scientists have proposed targeting polar bear conservation efforts there.)

This has been obvious this year in the Chukchi and East Siberian Seas where you had a stretch of thicker sea ice linger well into summer (in fact, some of the ice remnants — though rotten — still show up in the satellite data from the region).

The fate of sea ice in the Arctic Ocean is determined by a complicated mix of factors, including the pressure changes, with the biggest loss of old thick ice resulting more from a great «flush» of floes than melting, Dr. Rigor and many other scientists tracking the region say.

Relatively large expanses of older, multiyear ice were observed in the Beaufort Sea with a modal thickness around 3.6 m, which was also somewhat thicker than has been observed in this region recently.

When sub-freezing winds removed much of the thick Arctic ice from this region in the 1990s when Arctic Oscillation shifted, walrus rapidly exploited the region's resources and over 120,000 walruses hauled around Wrangel Island.

The total area covered by thick older ice that survives one or more summers («multi-year ice») shrank 42 percent or 1.54 million square kilometers (595,000 square miles), leaving thinner first - year ice («seasonal ice») as the dominant type of ice in the region.

For example, if warming continued into the mid-21st century, they proposed, bears in the Central Canadian Archipelago, the Arctic Basin and East Greenland («Archipelago» and «Convergent» ice regions, gold and blue on the map) would likely do better because thick, multiyear ice would be replaced by first year ice.

Buoys show this ice moving into the East Siberian Sea, lending some support to the notion of thicker, more enduring ice in this region.

Aerial thickness surveys and ground - based sampling in the western Beaufort and eastern Chukchi Sea in April this year indicate that level ice in the region is well over 3 m thick and strong (due to low salt content; www.sizonet.org).

Furthermore, while the melting of floating sea ice does not directly affect sea level, the extra heat in the region is accelerating the melting of the Greenland ice sheet, a massive body of ice 3 kilometers thick.

Once the ice barrier at the top of the strait gives way, ice from the Arctic Ocean can spill over into this region, affecting navigation, but also providing a mechanism to reduce ice concentrations in an area of very thick ice in the high Arctic.

«This is not a case of thicker ice appearing in one region simultaneously with thinner ice appearing in another, induced perhaps by a change in surface winds or other transient conditions,» Dr. Rothrock said, noting that the decrease was widespread in the central Arctic Ocean, and most pronounced in the eastern Arctic.

* Ironically, global warming seems to be causing more precipitation in the region, leading to thicker ice.

In this region, level first - year ice was below 1 m thick with ponds deep or melted through.

Driven primarily by atmospheric stresses, these ice bridges are formed when sufficiently thick ice «jams» during the course of its flow between land masses, resulting in a region of stationary compacted ice that is separated from a region of flowing open water (a polynya) by a static arch.
