When highly degraded, lowland thermokarst landscapes are flooded by the sea, and thermokarst lagoons, lakes, and the sea become connected with each other, complex lagoon systems are formed. Consequently, a natural gradient of marine submergence age and connectivity emerges within the system with old...
