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 SR50A) above the ice, and the ice/ocean interface, from the sonar altimeter (AirMar) below it, using the fixed distance between the two sounders. Processed by the CRREL/Dartmouth program.

Derived from the acoustic snow sounder (Campbell Scientific SR50A) 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 SR50A); moves down with surface melt. Height relative to the ice surface at installation (0 m, up positive).

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