英文摘要: The study of long-chain alkenones in the Ocean Drilling Program (ODP) core 1202B reveals a sub-centennial resolution record of sea surface temperature (SST) in the southern Okinawa Trough for the past 15. thousand. years (kyr). From the Deglaciation to Holocene, SST varied from 21.1 to 26.5. °C. The presence of Bølling (15.0-14.2. kyr. BP) and Allerød (13.7-13.4. kyr. BP) warming phases, Older Dryas (14.2-13.7. kyr. BP) and Younger Dryas (12.8-11.6. kyr. BP) cold periods reflects a tight teleconnection of climate between the Okinawa Trough and the North Atlantic region in the last Deglaciation. After rapidly increased and reached the maximum at ~. 7.4. kyr. BP, SST in the southern OT gradually decreased, corresponding with the lowering of northern hemisphere summer solar insolation. However, a series of abrupt SST drops were identified at ca. 8.6-8.1, 5.8-4.8, 4.1-3.9, 3.0-2.5, 1.6-1.3 and 0.6-0.5. kyr. BP, which cannot be explained by solar insolation changes alone, and instead are mediated by a complex sun-ocean-atmosphere coupling. © 2015 Elsevier B.V. Citation statistics:
