The Coastwatch Survey is designed to give an overview of the state of the coast. It involves volunteers from all walks of life checking their chosen 500m stretch of coast (survey unit) once around low tide, and jotting observations down on the survey questionnaire while on the shore. This citizen science work can be augmented with water tests. Data is then collected and pooled to provide a snapshot of state in areas surveyed at that time – see examples from Ireland N and S below.

IN TRANSITION  – The Coastwatch survey was born in 1987 and has adapted over time with updates from paper maps to modern GIS and alignment to  EU water law like the MSFD, WFD, Waste and Nature law. 2017 is a year in transition where new methods and materials are being tried in different countries.  However some common base questions will be identical and will be pooled for a European report.
