Cryosphere
The cryosphere is the term which collectively describes the portions of the Earth’s surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground . Thus there is a wide overlap with the hydrosphere...

Snow
Snow is a form of precipitation within the Earth's atmosphere in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds. Since snow is composed of small ice particles, it is a granular material. It has an open and therefore soft structure, unless packed by...

Avalanche
An avalanche is a sudden rapid flow of snow down a slope, occurring when either natural triggers or human activity causes a critical escalating transition from the slow equilibrium evolution of the snow pack. Typically occurring in mountainous terrain, an avalanche can mix air and water with the...

Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...

Ice
Ice is water frozen into the solid state. Usually ice is the phase known as ice Ih, which is the most abundant of the varying solid phases on the Earth's surface. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions...

Permafrost
In geology, permafrost, cryotic soil or permafrost soil is soil at or below the freezing point of water for two or more years. Ice is not always present, as may be in the case of nonporous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of...

Ice core
An ice core is a core sample that is typically removed from an ice sheet, most commonly from the polar ice caps of Antarctica, Greenland or from high mountain glaciers elsewhere. As the ice forms from the incremental build up of annual layers of snow, lower layers are older than upper, and an ice...

under Dr. William O. Field, Director, in 1957. Between 1971 and 1976 it was operated by the U.S. Geological Survey, Glaciology Project Office, under the direction of Dr. Mark F. Meier.
In 1976, responsibility for the WDC for Glaciology was transferred to NOAA, Environmental Data and Information Service (EDIS), and the center moved to the University of Colorado at Boulder under the direction of Professor Roger G. Barry. In 1982, NOAA created the National Snow and Ice Data Center (NSIDC) as a means to expand the WDC holdings and as a place to archive data from some NOAA programs. In the 1980s and 1990s, support to NSIDC widened with NASA funding for the Snow and Ice Distributed Active Archive Center (DAAC) and NSF funding to manage selected Arctic

International interactions
International science and data management programs facilitate the free exchange of data and accelerate research aimed at understanding the role of the cryosphere in the Earth system. NSIDC contributes to a number of international programs. Most of these programs, only a few of which are mentioned here, fall under the aegis of the International Council of Scientific Unions (ICSU).NSIDC scientists participate in International Union of Geophysics and Geodetics (IUGG), International Association of Cryospheric Scientists (IACS), and in activities of the International Permafrost Association

Research
Researchers at NSIDC investigate the dynamics of Antarctic ice shelves, new techniques for the remote sensing of snow and freeze/thaw cycle of soils, the role of snow in hydrologic modeling, linkages between changes in sea ice extent and weather patterns, large-scale shifts in polar climate, river and lake ice, and the distribution and characteristics of seasonally and permanently frozen ground.
