Each season before sea ice travel can occur, we are given the task of drilling the ice for thickness at designated points in the bays around Casey, extending right down to Browning Peninsular. After the recent low temperatures and calm weather we had a good idea that the ice had thickened to a reasonable level for safe travel. So we thought we had better check it out.
SAR Leader Jason (PI, beautiful smiling man) and first responder Cam (dieso, me) confirmed this by picking a nice calm and cool day (-28 degrees) using the ice drill and measuring ice thickness to be up to 1100mm in some areas with it averaging out at about 600-700mm at most of the GPS waypoints. This is more than enough for foot and quad travel.
Although the sea ice travel has been opened for the season, it is also extremely important for us to remain vigilant with our testing and drilling as it is forever changing with large temperature variations (-32 to 0 degrees on Tuesday), underwater currents, large tide variations (which open up tide cracks) and hurricane force blizzards(140+km/hr on Thursday) that could see the sea ice disappear overnight.
I’m sure the drilling will be kept to a high standard as no one here wants to end up in the extremely cold water!
All in all, a good day, and sea ice travel for the season is now OPEN!
Cam, Team Dieso
