We have analyzed a data set of the Barents Sea “Summer” Ice Edge (late August; covering 442 years from 1579 to 2020. The data is based on ship-logs from European whalers, earlier explorers, and hunters in addition to images from airplanes and satellites in recent times. The transition of solar activities to a possible deep and long minimum in the present century may lead to Arctic cooling and the Barents Ice Edge (BIE) moving south this century. For the North Atlantic region, the BIE expanding south will have noticeable consequences for the ocean bioproduction from about 2040, and presumably also for planned ocean transport across the Arctic Ocean.
