The METOCEAN Ice Mass Balance Buoy was developed in partnership with CRREL (Cold Regions Research and Engineering Laboratory). Its instrumentation is used to measure ice thickness and ice temperature, and to acquire meteorological and upper oceanographic data.
The instrumentation of the METOCEAN Ice Mass Balance Buoy consists of a Campbell Scientific Data logger, an Argos transmitter, a Thermistor String, and above ice and below ice Acoustic Sounders measuring the positions of the surface and bottom within 5 mm. In addition to the mass balance instrumentation, the buoys also have a GPS, a barometer, and an air temperature sensor.
The Thermistor Strings are manufactured out of PVC rod with YSI thermistors spaced every 10 cm. These rods are easily connected to assemble strings that are extended from the air through the snow and ice into the upper ocean. The thermistor accuracy is better than 0.1 C.
