K.R. Ludwig D.R. Muhs K. R. Simmons Barney J. Szabo 1994 <p><span>Thorium-230 ages of emergent marine deposits on Oahu, Hawaii, have a uniform distribution of ages from ∼114,000 to ∼131,000 years, indicating a duration for the last interglacial sea-level high stand of ∼17,000 years, in contrast to a duration of ∼8000 years inferred from the orbitally tuned marine oxygen isotope record. Sea level on Oahu rose to ≥1 to 2 meters higher than present by 131,000 years ago or ∼6000 years earlier than inferred from the marine record. Although the latter record suggests a shift back to glacial conditions beginning at ∼119,000 years ago, the Oahu coral ages indicate a near present sea level until ∼114,000 years ago.</span></p> application/pdf 10.1126/science.266.5182.93 en American Association for the Advancement of Science Thorium-230 ages of corals and duration of the last interglacial sea-level high stand on Oahu, Hawaii article
