Our History

NSIDC's roots go back to 1957 when a World Data Center (WDC) for Glaciology was established to archive all available glaciological information. The WDC was established by the American Geographical Society under Director William O. Field. The United States Geological Survey (USGS) Glaciology Project Office operated the WDC between 1971 and 1976 under the direction of Mark F. Meier.

The organization that we today call NSIDC started to take form in 1976, when the USGS transferred responsibility for the WDC to the National Oceanic and Atmospheric Association (NOAA) Data and Information Service, and the center moved to the University of Colorado in Boulder (CU Boulder) under our founding director, Professor Roger G. Barry. At CU Boulder, the WDC landed first at the Institute for Alpine and Arctic Research, then moved over to the Cooperative Institute for Research in Environmental Sciences (CIRES) in 1980.

In 1982, NOAA designated the center as the National Snow and Ice Data Center (NSIDC) with the mission to expand the WDC holdings and as a place to archive data from some NOAA programs. Initially, the center had just a physical library, two staff members, and a budget of $50,000 per year. However, the partnership with CIRES strengthened the ability for NSIDC to expand its data management and stewardship activities and develop a strong scientific research portfolio, focused on the cryosphere and its impacts on the rest of the planet.

In the 1980s and 1990s, NSIDC began to grow as a result of:

Office of Naval Research (ONR) funding to study sea ice processes, which supported a number of graduate students;
NASA funding for the National Snow and Ice Data Center Distributed Active Archive Center (DAAC);
National Science Foundation (NSF) funding that supported varied research in the cryosphere and the management of selected Arctic and Antarctic data and metadata.

As public interest in the cryosphere has grown, so has NSIDC’s research efforts, notably in areas of sea ice, permafrost, and the Greenland and Antarctic Ice Sheets. In the decades since 2000, research and data sets focused on the increasing impacts of a warming climate on the polar regions, permafrost, seasonal snow, and glaciers have made NSIDC the go-to center for public and scientific interest. NSIDC continues to receive large awards for management of the Snow and Ice DAAC, and for other data management efforts, as well as a robust research group that receives grants for data analysis and polar and alpine field investigations.

Today, NSIDC is a center of over 90 staff, researchers, and students, and is respected throughout the world for its data management and cryospheric research.

The early years

1957—The World Data Center for Glaciology is established by the US National Committee for the first International Geophysical Year (IGY) to archive all available glaciological data and information. The WDC in the United States joins a network of World Data Centers for Glaciology in other countries.

1972—The pilot study preceding the Arctic Ice Dynamics Joint Experiment program begins. NASA launches the Electrically Scanning Microwave Radiometer (ESMR), a single-frequency instrument that can monitor sea ice extent in polar darkness and in all weather conditions; Data from ESMR are available from the NASA NSIDC Distributed Active Archive Center (DAAC).

1975—The Arctic Ice Dynamics Joint Experiment (AIDJEX) program, a major sea ice experiment designed to answer questions about how sea ice moves and changes in response to the influence of ocean and atmosphere, begins. NSIDC stores and manages several data sets from this project.

1976—The World Data Center for Glaciology is transferred from the US Geological Survey to the University of Colorado Boulder under Roger Barry. This is when the organization later known as NSIDC starts to take form.

1978—NASA launches the Scanning Multichannel Microwave Radiometer (SMMR) aboard the Nimbus-7 satellite, marking the initiation of the modern satellite sea ice record. NASA later contracts with NSIDC to archive and distribute the resulting sea ice data.

1982—NOAA officially establishes NSIDC as part of the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder.

1983—NASA awards NSIDC a grant to archive Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) passive microwave sea ice data, which continues to the present with SSM/I and SSMIS instruments.

1985—NSIDC receives a major research award from the Office of Naval Research to study Arctic sea ice processes; several graduate students are subsequently brought aboard, acting as a major spark to NSIDC’s cryospheric research arm. As an important part of this effort, submarine sonar data are analyzed to address Arctic sea ice thickness.

1987–The first of the Special Sensor Microwave/Imager (SSM/I) sensors is launched onboard Defense Meteorological Satellite Program (DMSP) satellites. This series of satellite passive microwave radiometers continue to add to the sea ice satellite record, and data from these instruments are managed by and available from the NSIDC DAAC.

1990s to 2000s

1990—NSIDC receives funding from the National Science Foundation (NSF) for the Arctic System Science (ARCSS) Data Coordination Center (ADCC), which aims to collect all ARCSS-related data and provide for its preservation through long-term, off-site archiving.

1993—NSIDC quickly grows when it receives its first NASA Distributed Active Archive Center (DAAC) contract to steward cryospheric and related geophysical data from NASA Earth Observing Missions. This contract also expanded NSIDC research for the organization by including funding to support early career scientists conducting DAAC-related research, bringing several new researchers to the organization and expanding the scientific research capabilities of NSIDC.

1994—NSIDC launches its first website.

1996—The NOAA program at NSIDC (NOAA@NSIDC) begins with the goal of preserving data over the long-term to support current and future research. NOAA@NSIDC provides over 90 data sets about Earth's fast-changing frozen regions. The Antarctic Data Coordination Center (ADCC), which provides a research data repository and Project Catalog for the NSF-funded U.S. Arctic Program community, is established.

1997—The Environmental Working Group Arctic Atlases on CD-ROM , a joint effort between the United States and Russia, are released. These atlases include Arctic observations from the 1950s through the mid-1990s and include Russian and Western perspectives on the Arctic climate system, including atmospheric, oceanographic, and cryospheric data, maps, histories, and facts about climate and weather. The year-long Surface Heat Balance of the Arctic (SHEBA) project is initiated, featuring freezing an icebreaker into the sea ice in the Beaufort Sea and collecting atmospheric, sea ice, and oceanic measurements.

1999—NSIDC begins managing the newly established Antarctic Glaciology Data Center (AGDC), funded by the NSF Office of Polar Programs, to document, preserve, and disseminate results from NSF-funded Antarctic research. The NASA Terra satellite launches and the NSIDC DAAC archives data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. The Global Land Ice Measurements from Space (GLIMS) initiative launches to inventory the world’s glaciers. The NSIDC DAAC manages GLIMS data from this initiative.

2000—NSIDC collaborates with the International Arctic Research Center (IARC) to serve as a central node of the International Permafrost Association’s Global Geocryological Data (GGD).

2002—The Frozen Ground Data Center (FGDC) is established with International Arctic Research Center (IARC) support. The NASA Aqua satellite launches, and NSIDC DAAC archives data from the MODIS and Advanced Microwave Sounding Radiometer - Earth Observing System (AMSR-E) instruments. The Antarctic Megadunes project, a three-year research expedition, begins. The Glacier Photograph Collection, an online, searchable collection of photographs of glaciers that serve as historical records, is launched. The Sea Ice Index launches to provide a quick look at Arctic-wide changes in sea ice. A large portion of Antarctica’s Larsen B Ice Shelf disintegrates after record summer warmth and melting. NSIDC’s announcement of this event, made in concert with British Antarctic Survey (BAS) and Argentina’s Division National Antartico, becomes a global news story.

2003—The NASA Ice, Cloud, and land Elevation Satellite (ICESat) satellite launches to measure ice sheet mass balance, cloud and aerosol heights, and land topography and vegetation characteristics. The NSIDC DAAC archives data from the Geoscience Laser Altimeter System (GLAS) instrument on ICESat.

2004—The Frozen Ground Data Center program ends, though the data remain available in the NSIDC data catalog.

2006—NSIDC scientists begin the Arctic Sea Ice News & Analysis (ASINA) page with NASA funding, which provides daily images and regular analysis on Arctic sea ice conditions. IceTrek, a two-year Antarctic research expedition project, begins. NASA launches the Making Earth System Data Records for Use in Research Environments (MEaSUREs) program to produce unified data records critical to understanding Earth system processes and in assessing variability, long-term trends, and change in the Earth system. NOAA releases its first annual Arctic Report Card, a peer-reviewed publication that focuses on the current state of different components of the Arctic environmental system relative to historical records. NSIDC scientists regularly contribute to the Arctic Report Card. NSIDC and Argentine researchers from the IceTrek project land on two icebergs calved off the Antarctic Peninsula and install a battery of science instruments on each. NSIDC tracks the movement of these icebergs over the following months as they drift northward into warmer waters and break apart. The research provides insight into the process of glacier-fed ice shelf disintegration, which occurs infrequently but has serious implications for sea level.

2007—The Exchange for Local Observations and Knowledge of the Arctic (ELOKA) program is established at NSIDC with NSF funding to foster collaboration between resident Arctic experts, Indigenous communities, and visiting researchers. ELOKA creates online products that facilitate the collection, preservation, exchange, and use of local observations and Indigenous Knowledge of the Arctic. A 2007 Nobel Peace Prize is awarded to the Intergovernmental Panel on Climate Change (IPCC) and to former US Vice President Al Gore for informing the world about the important issue of human-caused climate change. NSIDC scientists are among the many experts who contribute to the IPCC's efforts. Former Vice President Al Gore visits NSIDC and is briefed by the science team on climate change impacts at the poles. NSIDC scientists publish a widely cited paper showing that the observed rate of Arctic sea ice loss is faster than predicted by climate models.

2008—The NSF-funded Sea Ice Outlook, a forum for researchers to share their predictions of the seasonal minimum (September) Arctic sea ice extent, is initiated. NSIDC gains global attention for its analysis of the record low September 2007 sea ice extent.

2009—The NASA Operation IceBridge airborne mission is established to bridge the gap in data between ICESat/GLAS and the planned ICESat-2 mission. The NSIDC DAAC archives resulting IceBridge data. The NSF-sponsored Larsen Ice Shelf System, Antarctica (LARISSA) expedition, a large, interdisciplinary, multi-institute study to explore every aspect of the Larsen Ice Shelf region, begins. NSIDC researchers travel to the Larsen Ice Shelf region as part of LARISSA. NSIDC works with Clyde River residents to launch the Silalirijiit Project, a collaborative research project to increase the community’s access to weather information by establishing a modest weather station network and documenting Inuit knowledge of weather, weather indicators, and weather forecasting; the project lasts until 2023. Mark Serreze becomes NSIDC’s director following Roger Barry’s retirement.
