Monthly Weather Review 131(5): 845-861.</Reference><Summary><Abstract>This data set consists of estimates of mean values of sea-ice thickness and sea-ice draft in meters computed from three different input data sets: sea ice draft from Upward Looking Sonar (ULS) mounted on submarines, sea ice draft from ULS mounted on bottom-anchored moorings, and a simulated ice-thickness model. The data span from 1979 to 2004 and cover two regions centered around the North Pole.</Abstract></Summary><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>http://dx.doi.org/10.7265/N53N21BT</URL><Description>Documentation</Description></Related_URL><Related_URL><URL_Content_Type><Type>GET DATA</Type></URL_Content_Type><URL>https://noaadata.apps.nsidc.org/NOAA/G02194/</URL><Description>HTTPS</Description></Related_URL><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>http://nsidc.org/data/g01360.html</URL><Description>Submarine Upward Looking Sonar Ice Draft Profile Data and Statistics</Description></Related_URL><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>http://nsidc.org/data/g01961.html</URL><Description>Environmental Working Group Joint U.S.-Russian Atlas of the Arctic Ocean</Description></Related_URL><Related_URL><URL_Content_Type><Type>PROJECT HOME PAGE</Type></URL_Content_Type><URL>http://psc.apl.uw.edu/research/projects/projections-of-an-ice-diminished-arctic-ocean/</URL><Description>Projections of an Ice-Diminished Arctic Ocean - Retrospection and Future Projection</Description></Related_URL><Metadata_Name>CEOS IDN DIF</Metadata_Name><Metadata_Version>VERSION 9.9</Metadata_Version><DIF_Creation_Date>2011-10-18</DIF_Creation_Date><Last_DIF_Revision_Date>2025-12-04</Last_DIF_Revision_Date><Extended_Metadata><Metadata><Group>NSIDC</Group><Name>Version Summary</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Minor Version</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Current Version</Name><Value>1</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Level of Service</Name><Value><Level>Basic</Level></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Full Dataset Citation</Name><Value>Moritz, R. &amp; Wensnahan, M.
