Encyclopedia entries, coastal atlas guides, science explainers, farming know-how and recipes — written by Tidewright’s scientists, engineers, chefs and field crews, and open to everyone.
As seas rise, coastal habitats migrate inland — unless seawalls block the way. How coastal squeeze threatens kelp forests and the intertidal zone, and what helps.

Meet the common murre, the foot-propelled pursuit diver of kelp-coast upwellings — a flying auk that hunts 100 metres down and raises chicks on bare cliffs.
