• The Operation IceBridge Portal is being decommissioned in June 2025 as NSIDC DAAC migrates to NASA Earthdata Cloud. On June 11, 2025, new data orders will no longer be accepted. Previous orders will remain accessible through the "Orders" tab until June 25, when the portal will be permanently removed. Learn more about alternative options and support here.

  • The NSIDC DAAC is retiring access to its legacy, on-premises data archive and transitioning to the NASA Earthdata Cloud as the primary data archive. View planned retirement dates at https://nsidc.org/data/user-resources/help-center/when-will-legacy-premises-archive-be-retired.
