Given the rapid changes that are under way in Arctic sea ice extent, Remote Sensing of Sea Ice in the Northern Sea Route is a timely work. The Northern Sea Route (NSR), along the Arctic coast of Russia, has a long history, dating back to 1932, when the Soviet Union established the NSR administration to develop hydrometeorological services. Shipping along the sea route peaked in the 1980s, but there is renewed interest associated with a lengthening ice‐free season and mineral exploitation. Since July 1991, the NSR has been open to all merchant vessels.
