Submarine Upward Looking Sonar Ice Draft Profile Data and Statistics, Version 1

This data set consists of upward looking sonar sea ice draft data collected by submarines in the Arctic Ocean.
It includes data from both U.S. Navy and Royal Navy submarines. Data are provided as ice draft profiles and as statistics derived from the profile data. Statistics files include information concerning ice draft characteristics, keels, level ice, leads, un-deformed and deformed ice.

本数据集收录了由潜艇在北冰洋采集的向上视声呐（upward looking sonar）海冰吃水（sea ice draft）数据。数据集涵盖美国海军与英国皇家海军潜艇获取的相关数据。数据以冰吃水剖面（ice draft profiles）及由剖面数据衍生得到的统计结果两种形式提供。统计文件包含海冰吃水特征、冰脊（keels）、平整海冰（level ice）、冰间水道（leads）、未变形海冰（un-deformed ice）与变形海冰（deformed ice）的相关信息。
