我们根据南部大洋大西洋区南纬 53°活塞岩心分析结果重建南大西洋全新世南极表层水变化史。此岩心沉积速率较高 (全新世平均值为50 cm/ 1 0 3a) ,且位于亚南极的南大西洋 ,适用于古气候研究。钻位位于现代极地前缘带( PFZ)以南约 3°,冬季海冰边界以北约 2°。利用硅藻转换函
We reconstruct the history of the Antarctic surface water changes over the South Atlantic Ocean based on the analysis of the 53 ° P cores at the southern latitude of the Atlantic Ocean. This core has a higher sedimentation rate (Holocene average 50 cm / 10a3A) and is located in the sub-Antarctic South Atlantic and is suitable for paleoclimate research. The drill bit is located about 3 ° south of the PFZ and about 2 ° north of the winter sea-ice boundary. Use of diatoms conversion letter
