A number of Welsh universities are teaming up to test whether parts of the Pembrokeshire coastline have the potential for renewable marine energy.
Operation Celtic Odyssey will see an environmental assessment of the St David's peninsula and the adjacent coastline around Ramsey Sound.
The area has already been identified by the Welsh Government as a potential site for tidal energy generation.
Cardiff, Swansea, Aberystwyth and Bangor universities are taking part.
Pembrokeshire College is also involved in the two-week project to study the environmental and engineering impact of placing a turbine underwater between the mainland and Ramsey Island.
