Summary of activities from 2020-22

The ongoing COVID pandemic severely curtailed activities of the ADMAP group in the 2020-22 reporting period. The main achievements were ongoing fieldwork and a number of new publications.

Meetings: The ADMAP group did not meet formally or informally in the 2020-22 period owing to restrictions related to the COVID pandemic. Online discussions have been continuing on ideas related to the concept of an ADMAP3 compilation, and future fieldwork programmes that might require international cooperation.

• PGMRE (Russia) completed ~12000 km of new airborne acquisition in Queen Mary Land in 2020, 2021, and 2022.
• Chinare (China) completed ~10000 km of new airborne acquisition in Princess Elizabeth Land in 2019/20.
