Iceberg Firn Temperatures, Antarctica, Version 1

Since November of 2005, 12 thermistors were planted in the upper 2.5 meters of the firn on iceberg C16, Antarctica. Temperature data are collected every 20 minutes and are transmitted via ARGOS satellite relay. Data are intended to provide a view of how firn temperatures change as an iceberg moves north into warmer climate.
