At Project Seagrass, we recognise that the pressures on our oceans are urgent, and that we can’t afford to do seagrass research purely for sake of it! Since day one our seagrass research has been geared towards making an impact in the real world.

The Seagrass Ecosystem Research Group (SERG), is a joint inter-disciplinary marine research collaboration between marine biologists in the school of Biosciences at Swansea University, and interdisciplinary marine scientists at the Sustainable Places Research Institute, Cardiff University.

The team are engaged in basic and applied research into the structure, function and resilience of seagrass meadows within a linked social-ecological system and the food security support these meadows provide.

Our research work is globally focussed and includes projects running in Europe, across the Into-Pacific, and the Caribbean and involves collaborators at a number of internationally leading institutes.
