National Marine Week is our celebration of all things marine. Despite the name, it lasts 15 fun-filled days to allow for the variation in tide times around the country.

WTSWW’s marine monitoring work gathers evidence for critical datasets, used to strengthen the resilience of Wales’ network of protected marine sites and the protection of the marine species found within these sites. Long-term, uninterrupted datasets are particularly important to assess broad population trends, filling knowledge gaps, and informing decisions about use of the marine environment.
