- The sublittoral zone extends from the low-tide line out to 200 meters.
- The marine red alga Chondrus crispus is an abundant species along the coasts of the North Atlantic and inhabits the intertidal and upper sublittoral zones of rocky shorelines.

- The paleoenvironments are interpreted as inner sublittoral and coastal lagoons environments with riverine and estuarine influence.
