The maps below show the sea ice coverage for each year during this time. In the maps, the blue areas represent locations covered by sea ice, the white areas represent liquid ocean water, and the gray areas represent land masses. Based on the maps, which of the following is most likely true about the period of time between 1983 and 2007 in this Arctic region?
