Norwegian seaport

For the Geo Quiz, we're looking for a Norwegian seaport up above the Arctic Circle: 240 miles north of the Arctic Circle to be more precise. It's in the extreme northeast corner of Norway, near the border with Russia. The port looks out onto a bay that's part of the Barents Sea. Cruise ships that ply these waters have to be on the lookout for floating icebergs and fjords. This northern city is also the northern-most stop for the Hurtigruten cruise line.
