Exempel på hur man kan använda PERMAFROST i en mening

• Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost under the tundra.
• This includes sea ice, ice on lakes or rivers, snow, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost).
• The BAM cost $14 billion, and it was built with special, durable tracks since much of it ran over permafrost.
• Demographic features of the population of Norway, including Jan Mayen, and Svalbard, where the hospital is not equipped for births, and no burials are allowed because of permafrost, include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects.
• In 2007, The New York Times reported that erosion made Newtok an island between the widening Ningliq River and a slough to the north, because Alaskan permafrost is melting due to climate change.
• The town lies just below the southern limit of sporadic permafrost in Alaska, and is strongly sheltered from the extremely wet Aleutian Low which drops most of its moisture on the opposite (eastern) side of the mountains.
• In 1997, a team of scientists led by Johan Hultin exhumed the frozen remains of an Iñupiat woman who had been buried in the permafrost in a gravesite near Brevig Mission in a successful attempt to recover RNA from her lung tissue.
• It is atypical of polar climates in having winters sufficiently moderated by the sea that permafrost is merely sporadic, and in seeing heavy late summer rainfall more typical of subpolar oceanic climates.
• This includes water in gaseous, liquid and frozen forms as soil moisture, groundwater and permafrost in the Earth's crust (to a depth of 2 km); oceans and seas, lakes, rivers and streams, wetlands, glaciers, ice and snow cover on Earth's surface; vapour, droplets and crystals in the air; and part of living plants, animals and unicellular organisms of the biosphere.
• Winter nutrition is weakened due to the location of the river basin in the permafrost zone and reaches the lowest values of 3-15 m3/s, the total winter runoff is 11% of the annual.
• Whilst the shallowest permafrost has a vertical extent of below a meter (3 ft), the deepest is greater than.
• Although the lander failed to fully deploy after it landed on the Martian surface, the orbiter has been successfully performing scientific measurements since early 2004, namely, high-resolution imaging and mineralogical mapping of the surface, radar sounding of the subsurface structure down to the permafrost, precise determination of the atmospheric circulation and composition, and study of the interaction of the atmosphere with the interplanetary medium.
• In June 2021, biologists reported the restoration of bdelloid rotifers after being frozen for 24,000 years in the Siberian permafrost.
• The long harsh winters and lack of sunshine allowed only mosses, lichens, and dwarf willows and shrubs to sprout low above the barren permafrost.
• During the summer, the surrounding plains are generally boglike, and include much permafrost and many pingos.
• On top of this permafrost, water flows out to sea via shallow, braided streams or settles into pools and ponds.
• Mummified carcasses preserved in permafrost and many bone remains of woolly rhinoceroses have been found.
• Studies also showed that the blasts would thaw the permafrost, making the slopes surrounding the harbor unstable, and negating any experimental value to be gained from using the project as a basis for extrapolation to other, warmer locations.
• The climate is very harsh because of the influence of the cold waters of Hudson and James Bays: most of the region is taiga characterized by discontinuous permafrost, but on the extreme northern coast there are – remarkably for a latitude of only 54°N – patches of true Arctic tundra and continuous permafrost.
• Thermokarst lakes develop by thawing of frozen ground (permafrost) and by subsequent modification by wind and water.
