ABSTRACT
During the Holocene, two (related) processes occurred worldwide along coasts: the postglacial sea level rise, which lasted to approximately 6000 BP, and an increase in temperature, which affected coastal areas predominantly at higher latitudes. An important question regarding the Holocene development of intertidal areas is whether the tides have remained the same. This can be assumed for the astronomical tides, but the actual tides along a coast are much influenced by the coastline configuration and the distribution of water depth. Both, in most areas, changed during the Holocene. A profile from King Sound shows a basal layer of nodular sand grading landward into mottled muddy sand with muddy mangrove deposits on top, laminated muds, and bioturbated muds, that are overgrown by the mangrove forest. On the seaward side the profile is cut off because of the erosion that dominates this area.
