National Marine Week is The Wildlife Trusts’ nationwide 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. 

The Wildlife Trusts are asking people to celebrate our blue planet by making a one-minute rockpool or coastal movie and posting it on Instagram or Twitter using #NationalMarineWeek; for the chance to be featured by The Wildlife Trusts on social media and win a prize. Film a fish, linger on a limpet or tell us about your favourite marine species - then post your minute movie to celebrate the sea!
