The coral record of last interglacial sea levels and sea surface temperatures
Ž . Ž . The rise and fall of the Last Interglacial LI sea levels and sea surface temperatures SSTs are evaluated using U-series dating combined with SrrCa ratios in corals from both stable and tectonically uplifted sites. Along the stable coastal margin of Western Australia, an extensive series of LI coral reefs occur at heights of 2–3 m above present-day sea level. These corals have a very tig...
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 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 کاملDetection of a dynamic topography signal in last interglacial sea-level records
Estimating minimum ice volume during the last interglacial based on local sea-level indicators requires that these indicators are corrected for processes that alter local sea level relative to the global average. Although glacial isostatic adjustment is generally accounted for, global scale dynamic changes in topography driven by convective mantle flow are generally not considered. We use numer...
