利用基于放射虫的转换函数，重建了北方冲绳海槽近10,500年来的年平均海表温度（SST）和季节温度差。底层SST的估算结果表明，整个全新世，年平均SST的变化呈现出三个阶段的变化趋势：（1）早全新世持续变暖，在8200年前后突然变冷，（2）中全新世相对稳定，SST高值持续到3200年; 3200 ~ 500 yrBP晚全新世SST明显下降。这一模式与中国大陆和世界其他地区的冰芯和陆地古气候记录相一致。在过去10,500年中，发现了5次海温突变的冷却事件，分别发生在距今300-600、1400、3100、4600-5100和8200年BP。我们的结果与记录的GISP 2冰芯和海洋沉积物在北大西洋地区的比较表明，这些冷却事件强烈耦合，这意味着可能显着的高纬度和低纬度地区之间的气候相关性。
Using a radiolarian-based transfer function, mean annual sea surface temperature (SST) and seasonal temperature range are reconstructed through the last 10,500yrs in the northern Okinawa Trough. Down-core SST estimates reveal that throughout the Holocene the changes of mean annual SST display a three-step trend: (i) an early Holocene continuous warming between 10,500 and 8500yrBP which ends up with a abrupt cooling at about 8200yrBP; (ii) a relatively stable middle Holocene with high SST that lasted until 3200yrBP; and (iii) a late-Holocene distinct SST decline between 3200 and 500yrBP. This pattern is in agreement with the ice core and terrestrial paleoclimatic records in the Chinese continent and other regions of the world. Five cooling events with abrupt mean annual SST drops, which occur at ∼300–600, 1400, 3100, 4600–5100 and 8200yrBP, are recognized during the last 10,500yrs. Comparison of our results with records of GISP2 ice core and marine sediment in North Atlantic region suggests these cooling events are strongly coupled, which implies a possible significant climatic correlation between high- and low-latitude areas.
