I downloaded the update from the 2017A webpage. The last frame from the 20th is very interesting. For a few data lines, on the 19th and 20th, one of the thermistors next above what I have assumed ice surface (depth=0 in the plots), seems getting anchored to 0C. Melting water from the snow? Last days seem pretty warm.
The temperature of the ice is getting close to melt temperature for what would be FYI, even well above it for the first 25cm of ice, which might mean I assumed ice surface in the wrong place. But I would not be surprised that this buoy was instead anchored to a residual of MYI of last year. Somebody I think mentioned that possibility.
The page has stopped giving bottom melt and snow depth, the database just shows 11 cm snow (
) and constant thickness of around 1.15 meters. I would expect more melt, top and bottom but who knows.
The bottom water is now clearly warmer, if only by 0.1C or so.
