Measurements of ice mass balance and temperature from autonomous Seasonal Ice Mass Balance (SIMB3) buoys deployed in the Central Arctic Ocean on the ArcWatch expedition in 2023

The dataset contains measurements made from three autonomous Seasonal Ice Mass Balance (SIMB) buoys. The buoys were deployed in the late summer of 2023 as part of the Alfred Wegener Institute ArcWatch Project. Each buoy measured position, barometric pressure, air temperature, and a vertical profile of temperature from the air, through the snow, through the ice, and into the upper ocean. An above ice downward looking sounder tracked the position of the surface and an underwater upward looking sounder tracked the position of the ice bottom. Sensors were placed every 0.02 meters (m) on the vertical temperature string. Measurements were made every four hours and results were transmitted via Iridium. There is one csv file for each SIMB.
