My bet is that they will get escorted by a Canadian icebreaker along with the Bremen. The Bremen started its cruise on 8/18 in Greenland, and is supposed to be in the Pond Inlet area on 8/22, so the Explorer may be cruising around east of the blockage until the Bremen catches up with them.

The per-diem for this cruise was really high, so I would guess that they have some contingency funds in the budget to pay for an icebreaker escort, but I am just speculating.

I wonder when they will be in internet range again?
