We present the design and implementation of a wireless sensor network (WSN) tailored for sea ice research. Our custom-built data acquisition unit employs Long Range (LoRa) radio technology and the Long Range Wide Area Network (LoRaWAN) protocol. We describe the deployment of a scientific measurement system in the vicinity of the Neumayer III research station in Antarctica, utilizing IoT technologies.This dataset contains different measurements to evaluate the performance of the LoRa radio link and the LoRaWAN protocol. In this work we use a data acquisition unit sending data via LoRa using the LoRaWAN protocol. The data acquisition unit is a custom made electronics designed to sample data from connected sensors used for sea ice research in Antarctica. Three datasets are available to evaluate the performance of the LoRa radio technology and the LoRaWAN protocol: one range test on a motor boat in Germany and two range tests performed in Antarctica near the Neumayer III station.
