Amino acid racemization of Neogloboquadrina pachyderma from the Arctic Ocean

The long-term rate of racemization for amino acids preserved in planktonic foraminifera was determined by using independently dated sediment cores from the Arctic Ocean. The...

本研究利用取自北冰洋（Arctic Ocean）、经独立定年的沉积物岩芯（sediment cores），测定了保存在浮游有孔虫（planktonic foraminifera）中的氨基酸的长期外消旋作用（racemization）速率。
