海洋孢粉形态数据与海面水文学的其他指标（浮游有孔虫组合和氧同位素）相结合，被用来破译末次冰期到间冰期过渡期间寒冷事件对爱琴海北部地区的影响。这些数据取自海洋沉积物岩心 GeoTü SL152 和 GeoTü SL148，表明海因里希 1 号和新仙女木期寒冷事件对爱琴海北部的地表水状况产生了强烈影响。海洋孢粉形态组合的变化与爱琴海北部边境的陆地植被和气候（即基于花粉组合的降水和温度重建）的变化相关。爱琴海地区对海因里希事件 1（H1，约 17.5 至约 15.7cal ka BP）和新仙女木事件（约 12.6 至约 11.7cal ka BP）事件的气候响应在震级上相似（年平均气温在 ∼6 到 10°C 之间，年平均降水量在 ∼300 到 11.7cal ka BP 之间）。 ～450 mm）。然而，与之前已经寒冷的情况相比，上半年的年气温下降幅度较小（<3°C）。另一方面，从当地相对温暖湿润的阿勒罗德间质层到新仙女木期的过渡，见证了年气温下降 6°C 和年降水量减少 300mm，后者在大约 10 年内突然发生。 150 一个。新仙女木期结束后，爱琴海北部地区天气恢复温暖。 11.6 卡血压。版权所有 © 2011 约翰·威利父子有限公司
Marine palynomorph data paired with other indicators of sea‐surface hydrography (planktic foraminiferal assemblages and oxygen isotopes) were used to decipher the impact of cold events on the northern Aegean region during the last glacial to interglacial transition. The data, which were derived from marine sediment cores GeoTü SL152 and GeoTü SL148, point to a strong impact of the Heinrich 1 and Younger Dryas cold events on surface‐water conditions in the northern Aegean Sea. Shifts in marine palynomorph assemblages correlate with changes in terrestrial vegetation and climate (i.e. precipitation and temperature reconstructions based on pollen assemblages) in the northern borderlands of the Aegean Sea. The climate responses of the Aegean region to Heinrich event 1 (H1, ca. 17.5 to ca. 15.7 cal ka BP) and Younger Dryas (ca. 12.6 to ca. 11.7 cal ka BP) events appear similar in magnitude (with mean annual temperatures between ∼6 and 10°C and mean annual precipitation between ∼300 and ∼450 mm). However, the annual temperature decline during the H1 relative to the preceding already cold conditions was minor (<3°C). The transition from the relatively warm and humid local equivalent of the Allerød interstadial to the Younger Dryas, on the other hand, witnessed an annual temperature decline of 6°C and an annual precipitation decrease of 300 mm, the latter occurring abruptly within only ca. 150 a. The return to warmer conditions in the northern Aegean region after the Younger Dryas was completed at ca. 11.6 cal ka BP. Copyright © 2011 John Wiley & Sons, Ltd.
