Radiolarian-based sub-surface temperatures in sediment core MD19-3575CQ

We present new records in four sediment cores of the Indian sector of the Southern Ocean. Radiolarian based subsurface temperatures (subST) were reconstructed using SORAD as a training dataset (Lawler et al., 2021; Civel-Mazens et al., 2023) with the Imbrie and Kipp Method applied to log transformed data.本研究报道了南大洋印度洋扇区4个沉积岩芯的全新记录。基于放射虫的地下温度（subsurface temperatures, subST）序列采用SORAD作为训练数据集进行重建（Lawler等，2021；Civel-Mazens等，2023），并将伊姆布里-基普法（Imbrie and Kipp Method）应用于对数转换后的数据。
