The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America. The Last Glacial Period caused a much lower global ...
The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
"The Arctic air coming through Jan. 15th can be the coldest of the winter so far," Anderson said. "This batch of Arctic air will have a vast zone for fresh snow cover to work with and a direct ...
"Typically, lake-effect snow events become less severe deeper into the winter season, but with the lakes still under 20% ice coverage and warmer than average, another impressive event is expected ...
The DNR cited Lake Winnebago, Wisconsin's largest lake, as a water prone to ice heaves and pressure ridges. And it named Green Bay as a water body in which ice can break away, stranding anglers.
For a period to be considered an interglacial, it changes from Arctic through sub-Arctic to boreal to temperate conditions and back again. An interstadial reaches only the stage of boreal vegetation. [1] The MIS 1 interstadial encompasses the entirety of the present Holocene interglacial, but the Wisconsin glaciation encompasses MIS 2, 3, and 4.
Nearly 80 million Americans will be below 0°F by next Tuesday when extremely cold Canadian / Siberian Arctic air descends on the Lower 48. The nationwide average low temperature will be only 6°F ...
Younger ice (first-year ice) is shown in darker shades, while older ice (four-year or older) is shown in white. This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The ...
