'Springtide' in old English means 'springtime'. This is harvest season for the seaweed crop. A spring tide is also the time when the tide "springs forth" during the new and full moon, giving us the highest and lowest tides of the month.

In partnership with the Herring Gut Learning Center in Port Clyde, Maine we also operate a research and teaching aquaculture nursery at the Herring Gut Saltwater Laboratory..  This partnership also includes participating the in the innovative First Work Program at Herring Gut.
