Elevation Datasets and Quaternary Mapping The ~600 km2 airborne lidar dataset (0.5-m-resolution) that aided our field mapping and profiling of Quaternary river terraces along the Sacramento River channel was acquired from the California State Department of Water Resources
A standard 10-m-DEM downloaded from the USGS elevation dataset was used for the portions of the study area not covered by the lidar dataset and aided field mapping and construction of the topographic profile traversing the older Quaternary units of the Red Bluff Formation (Fm) and Coleman Forebay basalt (Blake et al, 1999)
Summary
CONTENTS Datasets and additional methodological details Table DR1: Optically Stimulated luminescence (OSL) sample information, measurements, dose rates, and age results. The duripan soils developed within the T3 and T4 terrace deposits indicate these suggest these are relatively older surface (Flach et al, 1969). The potential for partial bleaching (incomplete resetting) of quartz grains presents a common uncertainty with OSL dating of fluvial sediments using aliquots, resulting in high dispersion amongst the luminescence measurements and artificially older depositional ages (e.g., Rettenour, 2008).
