IMB 2006D was deployed in the Laptev Sea on 30 August 2006 in first-year ice (DAMOCLES, IABP). Co-located instruments: POPS, Sound Source.

From the archive's thermistor depth labels.

Ice mass balance buoy (IMB) from the CRREL/Dartmouth program.

Longitude from Argos Doppler positioning.

Time of the record in Unix format (seconds since 1970-01-01 UTC).

Derived, not measured directly: the distance between the snow/ice interface, from the acoustic snow sounder (Campbell Scientific SR50) above the ice, and the ice/ocean interface, from the sonar altimeter (Benthos PSA-916) below it, using the fixed distance between the two sounders. Processed by the CRREL/Dartmouth program.

Derived from the acoustic snow sounder (Campbell Scientific SR50) mounted above the surface: snow surface minus the snow/ice interface. Processed by the CRREL/Dartmouth program.

Air temperature (Campbell Scientific CS107 probe) in a radiation shield above the ice.

Snow/ice interface from the acoustic snow sounder (Campbell Scientific SR50); moves down with surface melt. Height relative to the ice surface at installation (0 m, up positive).

Ice/ocean interface from the sonar altimeter (Benthos PSA-916); moves with bottom growth and melt. Height relative to the ice surface at installation (0 m, up positive).
