This project is a part of a 30 ECTS master thesis conducted at the Royal Institute of Technology, Sweden. The fieldwork consists of gravity measurements along several profile lines around the area of Billefjorden on 20-24 of April 2022. The gravity data will be complemented with magnetic measurements. The new measurements will further be integrated with different datasets in Petrel. The project is a cooperation with RIS-11827, where gravity profiles will be conducted across the Central Spitsbergen Basin. Together with this project, a large area can be mapped and interpreted.
