Sea Ice Edge Location and Extent in the Russian Arctic, 1933-2006, Version 1

The Sea Ice Edge Location and Extent in the Russian Arctic, 1933-2006 data are derived from sea ice charts from the Arctic and Antarctic Research Institute (AARI), St. Petersburg, Russia. Provided here are sea ice edge locations, where identifiable, in each AARI ice chart and monthly and seasonal mean sea ice extents for each of the marginal seas in the Russian Arctic derived from these ice edges. The original AARI charts were constructed primarily to assist operations in the Northern Sea Route. The digital version, from which this data set is derived, is titled Sea Ice Charts of the Russian Arctic in Gridded Format, 1933-2006.

1933-2006年俄罗斯北极海域海冰边缘位置与范围数据集，其数据源自俄罗斯圣彼得堡北极与南极研究所（Arctic and Antarctic Research Institute, AARI）编制的海冰冰情图。本数据集收录了每份AARI冰情图中可识别的海冰边缘位置，以及基于这些冰缘数据计算得到的俄罗斯北极各边缘海的月均与季均海冰范围。原始AARI冰情图的编制初衷主要是为北极东北航道（Northern Sea Route）的作业提供辅助支持。本次数据集所依托的数字化版本，题为《1933-2006年网格化格式俄罗斯北极海冰冰情图》。
