Paleo-water depth
WebMar 9, 2024 · Wei et al. (2024) proposed that there was a good correlation between TOC in sediments and paleo-water depth. So, we also draw the variation curve of TOC in these two sections to reflect changes in paleo-water depth. Larger values of TOC correspond to deeper water bodies and vice versa for deep water shelf environment.
