Ice Tracker data of Arctic sea ice during the MOSAiC expedition 2020-2021
20 Ice Trackers were deployed at the MOSAiC drifting site. The deployment of the trackers was made from the helicopter onboard RV Polarstern during Leg 5 of the expedition. The data contain the GPS positioning of the trackers (and the motion of the ice on which the trackers were deployed). The data record starts from early September 2020 and lasted until July 2021 for the longest-surviving trackers. The trackers started their drift near the North Pole and move to the south through the Fram Strait. The deployment of the trackers was done in collaboration with the MOSAiC ice team.
This work was funded by NERC MOSAiC program NE/S002545/1.

- Statement
- The data quality from the ice trackers can be affected by ice conditions and the position of the trackers. The trackers should be positioned upright to have a clear sky view for satellite reception for GPS and telemetry. Dynamic ice conditions can also affect the data quality and the failure of the trackers, e.g., ridging or deformation events can damage the ice trackers. In this case, the ice trackers stop transmitting the data. Therefore, some trackers were short-lived, while other trackers lasted longer. Some erroneous GPS positioning data can occur due to environmental factors mentioned above. These erroneous GPS positioning data have been removed through manual inspection of latitude and longitude coordinates. The ice trackers use a standard GPS receiver, so the typical positioning error is ~1-3 m.
