Dronning Maud Land 2022/2023

Due to the Corona pandemic, geodetic measurements could not take place in Dronning Maud Land during the past two seasons 2020/2021 and 2021/2022. Therefore, we are all the more pleased that geodetic work in the area of western Dronning-Maud Land will be possible again in the current Antarctic season 2022/2023.

This time we are involved in two expeditions with our working group:

Lutz Eberlein will visit the permanent GNSS stations Forstefjell and Kottas Mts. starting from the German Antarctic station Neumayer III within the framework of ANT-LAND 2022/2023 to perform maintenance work and an extension to include satellite communication (via Iridium). This work will be carried out in close cooperation with the Alfred Wegener Institute (Geophysics Section and Logistics). The transport will be carried out with Toyota Hilux vehicles converted by the company Arctic Trucks, which had already proven themselves during our expedition in 2020.

Eric Buchta and Benjamin Schröter are participating in the South African Antarctic Expedition (SANAE). On board the research icebreaker SA Agulhas II they will travel from Cape Town to Antarctica, where they will work based at the SANAE-IV station. The five to six GNSS measurement points will be reached by helicopters which are carried also by the ship. Since the initial measurements were carried out during the JUTEX 2001/2002 measurement campaign realized jointly with AWI Geophysics, we hope to be able to determine the ice-induced deformation of the Earth's crust over a period of more than 20 years by repeating the measurements.
