Diatom based sea surface temperatures in sediment core PS2606-6

We present new records in four sediment cores of the Indian sector of the Southern Ocean. Diatom based sea surface temperatures (SST) were predicted using a dataset containing 249 samples as per Crosta et al. (2020) and applying the Modern Analog Technique to relative abundances of 33 diatom taxa.本研究发布了南大洋印度洋扇区4个沉积物岩芯的全新观测记录。本研究参照Crosta等（2020）的方法，利用包含249个样品的数据集，通过对33个硅藻分类群的相对丰度应用现代类比法（Modern Analog Technique），反演得到了基于硅藻的海表温度（SST）。
