متن کاملInformation to “ Probabilistic assessment of sea level during the Last Interglacial ”
Nature of the indicators and depositional ranges. The sea level indicators take a variety of forms, including: constructional coral terraces that provide both geomorphological and ecological information; coral biofacies in limestones that provide ecological but not geomorphological information; erosional features such as wave-cut terraces, sea caves, bioerosional notches, and raised beaches; an...
متن کاملGlobal and Local Sea Level During the Last Interglacial: A Probabilistic Assessment
The Last Interglacial (LIG) stage (ca. 130 115 ka), with polar temperatures likely 3 5◦C warmer than today, serves as a partial analogue for low-end future warming scenarios. Multiple indicators suggest that LIG global sea level (GSL) was higher than at present; based upon a small set of local sea level indicators, the Intergovernmental Panel on Climate Change (IPCC)'s Fourth Assessment Report ...
متن کاملRapid sea-level fall and deep-ocean temperature change since the last interglacial period
We have dated Huon Peninsula, Papua New Guinea and Barbados corals that formed at times since the Last Interglacial Period, applying both 230Th and 231Pa dating techniques as a test of age accuracy. We show that Marine Isotope Stage (MIS) 5e ended prior to 113.18 0.7 kyr, when sea level was 319 m. During MIS 5b sea level was 357 m at 92.68 0.5 kyr, having dropped about 40 m in approximately 10 ...
متن کاملQuantification of the Greenland ice sheet contribution to Last Interglacial sea level rise
During the Last Interglacial period (∼ 130–115 thousand years ago) the Arctic climate was warmer than today, and global mean sea level was probably more than 6.6 m higher. However, there are large discrepancies in the estimated contributions to this sea level change from various sources (the Greenland and Antarctic ice sheets and smaller ice caps). Here, we determine probabilistically the likel...
