The latest temperature info from IMB buoy 2014I:
Pos: 75.97 N, 138.23 W
Air Temp: 0.64 C
Air Pres: 1016.15 mb
Snow Depth: 0 cm
Ice Thickness: 148 cm
looking at this over a longer period makes it even stranger:
temperatures reach 8degC which I can't believe to be water temp in a melt pond especially when the earliest occurance is on the 29th May ! when there wasn't surface water to be seen from Obuoy 1. Pity it isn't pointing at IMB2014I which would seem the more interesting view than the profiler.
edit for clarity:
The only clear feature from my plot which starts 05/26/2015 17:00 (x axis is hours) is that earlier the lower T7 sensor shows hardly any fluctuations while T6 10cm above it does fluctuate strongly but as it becomes exposed (it was just below the ice surface at installation I think) it starts to fluctuate.
looking through the Obouy11 images available as "movie" there is some sunshine on the 29th but not as much as on the later strong fluctuation episodes. these images are at the moment only available to the 16th June
