IMB 2013B reports that 3 cm has melted away in the last 24 hours or so, and the temperature underneath is increasing:
What do the thermistor data from last years' buoys look like for the second half of July? We know the surface melt is way behind last year, can you tell us anything about the bottom melt?
2012L is the only buoy located really close to that position in the Beaufort and thus it is the only valid comparison. As of 07/20/2013 we have
Current Buoy Data (07/20/2013):
Pos: 74.69 N, 145.80 W
Air Temp: 0.85 C
Air Pres: 1017.48 mb

Current Ice Observations (07/20/2013)
Snow depth : 0 cm (melted 06/18/2013)
Ice thickness : 266 cm
Since Deployment (08/27/2012)
Snow depth at melt onset: 15 cm
Snow melt: 15 cm (Began 06/09/2013)
Ice surface melt: 48 cm (Began 06/18/2013)
Ice bottom melt : 26 cm (Began 06/14/2013)
Ice bottom growth : 12 cm (Began 02/01/2013)

How exactly is 48cm of surface melt 'way behind', I ask?
