Permafrost zones extend over 50% of Canada's land area.
New data suggests that the Mississippi Delta is still sinking, but at a much slower rate than previously estimated.
Satellite are seeing changes in land surfaces in high detail at northern latitudes, indicating thawing permafrost. This releases greenhouse gases into parts of the Arctic, exacerbating the effects of climate change.
Geologists at the University of Washington found that a previously unseen landform on Mars could help provide a window into the geological history of the Red Planet.
Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based on new permafrost maps -- the most precise global maps around.
Internet information giant Google updated ocean data in its Google Earth application this week, reflecting new bathymetry data assembled by Scripps Institution of Oceanography, UC San Diego, NOAA researchers and many other ocean mapping groups from around the world.
Taking inspiration from the yellow fattail scorpion, which uses a bionic shield to protect itself against scratches from desert sandstorms, scientists have developed a new way to protect the moving parts of machinery from wear and tear.
When the water in the Mississippi River rose to 58 feet with a forecast of 60 feet or higher in May 2011, the emergency plan to naturally or intentionally breach the levees, established over 80 years prior, was put in motion.
A higher-than-normal 2010 melting season sped up the melting of ice in southern Greenland, causing sizable portions of the island's bedrock to rise somewhere about a quarter of an inch more than usual.
Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...
Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...
Badlands national Park is located in the southwest region of South Dakota. It holds 242,756 acres of land, with 64,144 acres comprising a protected wilderness area. The park was designated as a national monument in 1929 and established in 1939, but attained national park status in 1978. The Stronghold Unit area of the park is managed by the National Park Service and the Oglala Lakota tribe and holds many sights including those used for Ghost Dances in the 1890’s, a bomb and gunnery range...
A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....
