Marine Geohazards and the Blue Economy

A geohazard (or geological hazard) is a geological condition which represents - or has the potential to develop into - a situation leading to damage or uncontrolled risk. Hazardous marine geological events may occur at any time and the scientific community, marine industry, and governmental agencies must cooperate to better understand and monitor the processes involved in order to mitigate the resulting unpredictable damages. The European Marine Board will produce a foresight document to provide a state-of-the-art within this broad research field, identifying the key issues, and illustrating some examples of how research in this area can improve the assessment of risks to the Blue Economy.

Outputs

A foresight report on Marine Geohazards and their impacts to the Blue Economy will be published in late 2020.

Background

The major marine geohazards are coastal erosion, seawater intrusion, earthquakes, submarine landslides, subsidence, tsunamis, natural gas hydrate dissociation, seabed sand waves, shallow gas, overpressure strata, gas chimneys, mud volcanoes and mud diapirism. The advancement of deep-water exploration activities, the uncertainties of the consequences of climate change, the latest catastrophic global events (e.g. the 2004 Indian Ocean and 2011 Japan tsunamis), and the increasing human population densities in the world’s coastal regions are responsible for the increased importance and awareness related to marine geohazard research. Specific threats to society from marine geohazards are the disappearance of valuable land near the shorelines, devastation of coastal areas by landslide-generated tsunamis and the destruction of seafloor installations (e.g. communication cables, pipelines).

Marine geohazards are slowly gaining political attention at European and international level. “A safe ocean” is one of the six societal objectives of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030). In addition, “A Protective Europe” is one of the five future policy priorities for the European Union. The strategic planning of the Horizon Europe programme (2021-2017) also noted that impacts are expected from research and innovation activities to “improve disaster risk and societal resilience through better understanding of natural and man-made disasters and by the development of novel concepts and technologies to counter these risks”. In 2017 MEPs Gesine Meissner and Ricardo Serrão Santos hosted a “Gas Hydrates and Offshore Geohazards” event at the European Parliament, which concluded that offshore geohazards impede the development of Blue Economy and pose threats to ecosystem functioning. Marine geohazards may also hamper the effective implementation of policies such as the Maritime Spatial Planning (MSP) and Integrated Coastal Zone Management (ICZM), and in regions like the Mediterranean, marine geohazards can jeopardize economic activities and civil infrastructures.

It is essential to improve the knowledge and tools for identifying risks and set out a strategy for marine geohazard mitigation, in the context of other extreme events, such as meteotsunamis, as explained in European Marine Board’s Navigating the Future V.

Objectives

Marine geohazards have not been on the policy landscape in the past, and the EMB proposes an expert working group to produce a Future Science Brief (FSB). The FSB should focus on marine geohazards, and include reference to coastal interactions. It should highlight the need for marine scientific research and further understanding of marine geohazards, how these impact the Blue Economy and how they may be influenced by climate change and the wider earth system. It should make specific recommendations, on what can be done to cope with this issue, for scientists, European and national policymakers, offshore industry representatives, research funders and centres, international and European efforts, and NGOs.

Specific objectives include:

  • Define the state-of-the art in European research in this area;
  • Draft the main R&D needs to increase understanding and European capability of this topic;
  • Highlight scientific research and knowledge on marine geohazards, impacts on the Blue Economy, and connection with climate change and the wider earth system;
  • Build interdisciplinary relationships between geology and other relevant fields of research (offshore structural engineering, benthic biology, climate change, etc.).

Terms of Reference of the Working Group

Marine geohazards have not been on the policy landscape in the past, and the EMB selected an expert working group to produce a Future Science Brief (FSB) to make specific recommendations on what can be done to cope with this issue.
