CIR Process Age Inference Algorithm v1.0: scalable and consistent sedimentation rate modeling for ocean sediment cores via the Cox-Ingersoll-Ross process
15d ago
From the article
Deep-sea sediment cores provide a key archive of past climate, with geochemical measurements of microfossils providing both environmental information and age constraints; however, constructing continuous age-depth models is challenging due to sparse and uncertain direct dating (e.g., radiocarbon up to 50 kyr BP) and the need to integrate more densely sampled but indirect proxies such as benthic δ18O, which requires pattern alignment to reference stacks while maintaining physically plausible [...]
