Summary: | Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC44 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 10 April 2020. The thermistor chain was 4.16 m long and included sensors with a regular spacing of 2 cm. The resulting time series describes the evolution of temperature during the heating cycle of 20 s and after the heating cycle during the following 40 s as a function of geographic position (GPS), depth, and time between 10 April 2020 and 02 May 2020 in sample intervals of 6 hours. It also contains manually estimated positions of air-snow, snow-ice, and ice-water interfaces. The DTC was installed in the undeformed first-year ice next to RV Polarstern and remote sensing site RS4. Ice mass balance SIMBA 2020T79 was installed at Met City near the remote sensing site: doi:10.1594/PANGAEA.940712. |
