Welcome to SPLASHCOS

SPLASHCOS - Submerged Prehistoric Archaeology and Landscapes of the Continental Shelf - is a research network funded from 2009 to 2013 by the European Commission under its COST program (Cooperation in Science and Technology) as COST Action TD0902.

Its aim is to bring together archaeologists, marine geoscientists, heritage agencies and industrial organizations to research, manage and preserve the archives of archaeological and palaeoclimatic information locked up on the drowned prehistoric landscapes of the European continental shelf, and to disseminate that knowledge to a wider public.

For details of the programme and membership see the Memorandum of Understanding, the MoU Addendum, The COST Final Evaluation Report (2013),and the COST website. News Items about new activities inspired by SPLASHCOS will be reported here as they arise.
