I found this video over at CIMSEC where they posted a short review of the progress in the use of UAVs,
I had not been thinking of using UAVs from icebreakers, but it makes a lot of sense. As we have seen, flying helicopters in the Arctic is still a dangerous business. In addition to removing people from a relatively dangerous environment, UAVs have the potential advantage of much longer endurance. The UAV in the video is the Austrian built Schiebel S-100 that is used by the Chinese Navy as well as the French and German Navies and many other agencies.

If I remember correctly the Healy used a drone of some sort during its tanker escort last year into Nome, AK.
I think I recall that a privately owned shore based UAV provided some support.
A story of an ice-strengthened freighter using a small UAV to do ice recon. This size UAV are widely available to the general public for less than $1,000.

Among the experiments being done on Healy this year is the use of a small hand launched UAV. There is a video. The encouraging thing is that this UAV is certainly small enough to fly from a Patrol Boat, still it looks like it still needs some work on both the sensor package and the recovery technique (looked more like a crash on deck). Can’t help but think that something like the Scan Eagle would probably have done better, although this is certainly even cheaper. (Thanks to Lee for bringing this to my attention.)

Here is the CG news release on the UAS experiments on Healy: http://www.uscgnews.com/go/doc/4007/2231502/Multimedia-Release-Coast-Guard-conducts-first-Unmanned-Aircraft-System-deck-landings-aboard-Coast-Guard-Cutter-Healy
The Coast Guard and NOAA are using a UAV from Healey. I hope there is more to it than I see here: http://www.nationaldefensemagazine.org/archive/2014/December/Pages/CoastGuardNOAATestingDronesinArctic.aspx
This seems to be far cruder than Scan Eagle. https://chuckhillscgblog.net/2011/04/01/uavs-lets-try-this-one/
