Arctic sea ice
Sea ice pressure ridges are formed when flat areas of ice are driven into each other by wind and ocean currents.
A tripod supports light and temperature sensors that extend from the air above the ice down through the ice and into the ocean. The watertight enclosure to the left houses custom electronics, battery and a satellite modem to transmit data off the ic

Detail of the light string sensor - a 3.2 meter long circuit board with a RGB/IR light sensor every 5 cm. On the back side is a temperature string with temperature sensors every 2 cm. 224 sensors in total collect a vertical section of information t
Detail of the buoy electronics showing a purple custom circuit board with Arduino microcontroller, atmospheric pressure sensor, GPS, and connection to the external sensors. These instruments are paired with an Iridium modem. The buoy is left on the
Our deployment group and cluster of buoys included researchers from five universities.
This diagram shows how the light and temperature sensors are installed through the floating ice.
