From Depth Scale to Time Scale: Transforming Sediment Image Color Data into a High-Resolution Time Series

Abstract

High-resolution time-scales are important for the precise correlation of spatially distributed geological records, and further development of process-oriented models used to predict climate change and other terrestrial processes. The extraction of digital line-scan data from images of laminated sediments provides a tool for the rapid and non-invasive analysis of sedimentary records, including sediment and ice cores, and tree ring growth patterns.
