GPS Ice Tracking System [ice floe tracking system]

The Arctic is a very sensitive environment and thus is a good indicator of global climate trends. In particular, collecting data about the location of large sheets of ice can be very informative about the macroscopic trends of ice formation. In addition to the position of these ice floes, the air temperature and relative humidity as well as several other characteristics of the surrounding environment can provide a better long-term picture of ice formation in the Arctic.In this vein, we are proposing an autonomous unit capable of powering itself and communicating hourly via an internal modem its GPS position, air temperature, relative pressure, humidity and any other characteristics of its surrounding environment. The unit will have to be robust enough to operate at subzero temperatures and power itself for an extended period of time, possibly up to eight months.
