Abstract:

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.
