The Seas, Rivers, Islands and Coastal Areas Intergroup organises a discussion on offshore geohazard on 22 June 2017 at the European Parliament in Room ASP 3 H 1.
Offshore geohazards impede the development of blue economy and pose threats to ecosystem functioning. While resource exploration moves further offshore, it is essential to improve the tools and knowledge for identifying risks and set out a strategy for hazard mitigation.
Marine gas hydrates are ice-like solids stored in marine sediment and considered as the largest reservoir of methane, a potent greenhouse gas. Ocean warming and environmental change can induce gas hydrates decomposition causing methane release and further contributing to global environmental change. In addition, hydrate decomposition may destabilize the seafloor with subsequent threats from potential tsunamis and potential hazard consequences on seabed structures.
Supporting the Paris Agreement, UN Sustainable Development Goals and EC 2030 Agenda for Sustainable Development, this issue has challenges to build knowledge on the link between climate change, gas hydrate dynamics and seafloor stability, as well as to deliver an ecosystem study related to this phenomenon.
