Closing the sea level budget at the Last Glacial Maximum.
Establishing the volume of excess ice contained in the global ice sheets during the Last Glacial Maximum (LGM; ∼26,000–19,000 y ago) remains a longstanding problem in Ice Age climate dynamics. Expressed as the equivalent lowering of global mean sea level (GMSL), estimates of this value have varied from 105 (1) to 163 m (2), with many estimates suggesting ∼120 m (3). This wide range introduces s...
متن کاملIce sheets and sea level of the Last Glacial Maximum
This paper outlines the general issues regarding ice sheets and sea level of the Last Glacial Maximum (LGM), which formed the basis of an EPILOG Project workshop. Papers in this special issue of Quaternary Science Reviews provide a comprehensive assessment of these issues from the perspective of geological reconstructions of ice sheet extent, records of sea-level change, ice sheet modelling, ge...
متن کاملThe Last Glacial Maximum.
We used 5704 14C, 10Be, and 3He ages that span the interval from 10,000 to 50,000 years ago (10 to 50 ka) to constrain the timing of the Last Glacial Maximum (LGM) in terms of global ice-sheet and mountain-glacier extent. Growth of the ice sheets to their maximum positions occurred between 33.0 and 26.5 ka in response to climate forcing from decreases in northern summer insolation, tropical Pac...
متن کاملGlobal glacial ice volume and Last Glacial Maximum duration from an extended Barbados sea level record
Fundamental characteristics of the climate system during the most recent precessional cycle of the Earth’s orbit around the Sun consist of the final expansion of land ice to its maximum extent, the subsequent episode of deglaciation, and the variations of global sea level that accompanied these events. In order to address the important issue of the variation of continental ice volume and relate...
متن کاملQuantifying the Effects of Lower Sea Level on Tropical Pacific Climate during the Last Glacial Maximum
ACKNOWLEDGEMENTS First and foremost, I wish to thank my research advisor and co-advisor, Dr. Kim Cobb and Dr. Emanuele DiLorenzo. They have put a tremendous number of hours into this project while teaching me that conducting research is challenging, tiring, but more importantly, fun and inspiring. I also wish to thank Dr. Yen, both who introduced me to the world of academia. Working in both of ...
