Polar drift ice
by Saagar
The Svalbard archipelago is situated within the polar pack and drift ice area. The maximum extent of the drift ice during winter is as far south as Bear Island, but the warm Gulf Current leads Atlantic and North Sea water northwards and keeps a tongue of open water up along the western coast. Still, access to harbours of Ny Ålesund, and Svea and longyearbyen will be by icebreakers only during winter and spring. The northern and eastern areas of Svalbard are nearly permanently within the pack and drift ice belt. Normally, however, there is a possibility of travelling up to about 80 degrees north by cruise ship straigth north of Spitsbergen during the heigth of summer before hitting the pack ice. Circumnavigation of Svalbard may not be done all years due to pack ice and crushing drift ice around Edge island and the Hinlopen straight.Be aware of the restraints caused by the ice movements...
