Measurements of the sea-ice penetration depth below the sea surface (ice draft) have been made by U.S. submarines operating in the Arctic Ocean since 1958. These Arctic records will be obtained from the U.S. Navy, transcribed and analyzed, and placed in the public record. The data will be used to examine regional and seasonal changes in the ice thickness over the Arctic basin. Expectations are that the ice pack has become thinner over the last several decades. Long-term trends will be examined in collaboration with other scientists with more recent data and with data from other countries.

自1958年以来，在北冰洋作业的美国潜艇一直在测量海面以下的海冰渗透深度（冰吃水）。 这些北极记录将从美国海军获得，转录和分析，并放在公共记录中。 这些数据将用于研究北极盆地冰层厚度的区域和季节变化。 预计在过去的几十年里，冰层已经变得越来越薄。 将与掌握最新数据和其他国家数据的其他科学家合作研究长期趋势。
