Los pockmarks fueron identificados por primera vez en la plataforma de Nueva Escocia a finales de la decada de los sesenta, y se definieron como depresiones esfericas o semiesfericas con paredes escalonadas y fondos planos (King And MacLean, 1970).
The linear pockmark chains, particularly where faults occur, may present a potential zone of migration to the surface.
