Tombolo - A tombolo is a bar connecting an island with the coast. However, wave refraction around Durlston Head produces wave fronts from NE-SW along the coastline towards the north spit of Poole Harbour, generating a spit from the north. Dunes Dunes are landforms formed from sand deposits that have been blown off the beach. Beaches form in sheltered environments, such as bays. In addition to this spatial information, the data provides an understanding of the paleoenvironmental records of interactions between surface moisture, vegetation, and fire.
