Water and ice temperatures measured by thermistor probe in a melt pond during expedition PS122/5 (MOSAiC Leg 5) to the central Arctic in August-September 2020.

The temperatures at water depths of 0.015, 0.05, 0.1, and 0.2 m were measured by thermistor probe (TR-5120, T&D Corp., Nagano, Japan) and temperature data were stored in a data logger (TR-52i, T&D Corp.) at St. 1 melt pond during expedition PS122/5 (MOSAiC Leg 5) to the central Arctic in August-September 2020. In order to install the thermistor probe, we used stick longer than the diameter of the pond.
