Report on gravity measurements and replacement of an unmanned magnetometer in the Sor Rondane Mountains, Eastern Dronning Maud Land, 2013 (JARE-55)

Abstract

Gravity measurements, replacement of the unmanned magnetometer, and a reconnaissance flight to the Belgica Mountains were carried out in the Sor Rondane Mountains as a part of the 55 th Japanese Antarctic Research Expedition (JARE-55). The field party comprised two geodesists, one geomorphologists, and one magnetospheric scientist. The Belgian Antarctic Research Expedition (BELARE) and International Polar Foundation (IPF) supported this field expedition. Dronning Maud Land Air Network (DROMLAN) provided airborne access from Cape Town, South Africa to the Sor Rondane Mountains via Novolazarevskaya Airbase. The survey areas of this field expedition are the central parts of the Sor Rondane Mountains and the Belgica Mountains. This report summarizes the field expedition in terms of operations, logistics, and weather observations.
