A continuous record of temperature evolution over a sequence of Dansgaard-Oeschger events during Marine Isotopic Stage 4 (76 to 62 kyr BP) / A. Landais, and 8 others.

Abstract: | Uses two independent paleothermometry methods, one based on air isotopic measurements (δ¹⁵N and δ⁴⁰Ar), the other on combined measurements of water isotopes (δD and δ¹⁸O), to reconstruct temperature at NorthGRIP site over period 76 to 62 kyr BP (Dansgaard-Oeschger (DO) events 18, 19 and 20). Confirms associated warmings are larger than those conventionally depicted by water isotopes (11°C, 16°C and 11°C for DO 18, 19 and 20). Demonstrates that relationship between temperature and δ¹⁸O varies rapidly during last glacial period, even over a DO event. Temperature reconstruction over DO 19 agrees well with that predicted from simple climate models linking DO to iceberg discharges. |
