Swimming between two ice
holes in the relative shallows isn't too bad as it's quite
light and you can see the bottom, but this was out in much
deeper water 60m+. The sea-ice cuts out a lot of the
light reaching beneath it and in such deep water there is
nothing to see as a visual cue. The diver in this case is
dependent on his depth gauge to stay at the right level and
the line "drawn" by the skidoo on the surface that he is
following to the next hole.
Eventually, the next hole
comes into sight and light shines down like a beacon.
