​Our marine environment is hugely important to our bio-economy, transport, tourism and recreational sectors. It is also an important indicator of the health of our planet. 

Our cultural history is documented along our coastline through shipwrecks and coastal features such as lighthouses​.

Geological Survey Ireland, in partnership with the Marine Institute, jointly manages INFOMAR, Ireland's national programme focused on Seabed Mapping and enhancing understanding of our underwater landscapes.

Tsunami hazards & submarine landslides pose a significant threat to coastal communities in many part of the world.  Geological Survey Ireland's Marine and Coastal Unit is actively working on numerous programmes, projects and partnerships aimed at increasing our knowledge of the marine and coastal realm, developing new methods and tools for understanding coastal processes and taking action on climate change.  

Geological Survey Ireland featured in the first episode of the 2018 series of 10 Things to Know About… on RTĒ 1. The episode devoted to the science of the seabed and ocean floor shows the work of the DCCAE-funded INFOMAR project in Geological Survey Ireland and the role of GSI with the Dublin Institute of Advanced Studies in tsunami warning systems in the Atlantic Ocean.
