Holocene Paleoshoreline and Paleoenvironmental History of Palau: Implications for Human Settlement

Abstract: Information from cores into the offshore reefs of KomebailLagoon and into the coastal fringes of Babeldaob and neighboring islets allows the first well-constrained appraisal of the Holocene paleoshoreline history of Palau. Bulk subsidence of the island group since ∼5 kyr at a rate of ∼0.55 mm/yr is indicated jointly by both the offshore and the onshore datasets. Persistent subsidence of paleoshorelines since the initial human settlement of Palau has implications for the evolution of coastal paleoenvironments a… Show more

“…Reef transformation due specifically to sea-level fall, however, is inconsistent with the local geologic record. The Rock Islands have been undergoing subsidence and relative sea-level rise since the mid-Holocene highstand (Dickinson and Athens, 2007). Loss of habitat through reef and sand flat drowning would seem to be a greater concern, and at least for the Rock Islands, would be expected to adversely impact S. gibberulus populations.…”

“…Kirch and Hunt (1993:234-236) extend their model to suggest application not only elsewhere within American Samoa, but also in the search for early sites in the southern Cooks, the Australs and the Society Islands. Variants of the model have also been shown to have value for Mangaia in the Cooks (Kirch 1997b), Niuatoputapu in Tonga (Kirch 1988b) and more recently Palau (Wickler 2001b) -but see Dickinson and Athens (2007) for a useful corrective concerning the influence of subsidence for that last island group, perhaps also applicable to other cases.…”
