Project description
The Arctic Mid-Ocean Ridge is one of the slowest-spreading ridges in the world. Throughout this project, we will combine morphological, geochemical and geochronological results to understand how the tectonic and magmatic processes act together to control the volcanic activity on the seafloor. The project will focus on the crustal architecture and the production of basaltic melts at axial volcanic ridges (AVRs). High-resolution bathymetrical mapping by an autonomous underwater vehicle coupled with in-situ sampling using a remotely operated vehicle will be used for collection of the necessary data. Ultimately, we aim to get insights into the size and frequency of volcanic eruptions in the Norwegian-Greenland Sea.
