InterRidge Theoretical Institute 2019 - Hydrothermalism in 4D: current challenges and emerging issues

Banyuls-sur-mer, France Date: 18-21 November 2019

The 4th Theoretical Institute InterRidge will build on the current scientific momentum and emerging themes related to hydrothermal systems and how they interact with other oceanic components.
New challenges have been raised on the links between tectonic complexities and magmatic-hydrothermal processes, hydrothermal contribution to global ocean budgets (e.g. heat, carbon, iron), the dynamics and mechanisms of long-range interactions of vent systems as well as their role on deep-sea ecosystem functions and responses to global change. Building an integrated vision of hydrothermal processes over space and time, on which quantitative approaches and predictive models should be based, is of crucial needed. Beyond the opportunity to exchange on new technologies, interdisciplinary challenges (including capacity building and methods/tools sharing across disciplines), the Theoretical Institute aims to contribute to setting up the scene for the next decade plan, underlining critical knowledge gaps and perspectives for the current research momentum. Methodology and knowledge needs for biodiversity, mineral resource assessments and environmental impact monitoring will also be considered.

This Theoretical Institute will help bringing together ideas, concepts, expertise and know-how and that will help strengthening the fundamental frame and develop strategies to fill remaining gaps, while ensuring that the growing community of scientists interested in vent systems has access to suitable basic knowledge.
