Temporal and spatial distributions of Arctic sea ice thickness and pressure ridging statistics
Data form the unclassified literature were reviewed to determine the regional and seasonal distributions of sea ice thickness, pressure ridging statistics, frequency of occurrence of polynyas, and keel/sail height ratios. Seasonal and regional maps and histograms of these properties were constructed...
