= Bay of Fundy
{c}
The <Bay of Fundy> is a coastal basin in eastern Canada notable for large <tidal ranges>. Its <geometry> and the dynamical response of the connected bay system strongly amplify the incoming <semidiurnal tide>.
The important physical idea is forced motion of a basin: <water depth>, shape and friction determine its natural response, while the external astronomical tide supplies the drive. Large range is not a direct local <measurement> of an unusually strong <gravitational field>. Range also varies with location and the spring-neap cycle, so one quoted maximum does not characterize every <observation>.
