Supplementary Material Assessment of Short-Term Sediment Deposition Patterns Along the Palamós Submarine Canyon (NW Mediterranean) Using 234Th

Key Points

Sediment deposition patterns were assessed using 234Th measurements and regression metrics, highlighting significant findings.
Measured activity concentration was derived from 234Th, allowing better understanding of sediment dynamics in canyons.
Analysis included bulk density and excess activity concentrations to derive mixing rates effectively in sediment layers.
Understanding these sedimentation patterns is vital for predicting ecological changes in marine environments.

Abstract

Table S1: Downcore dry bulk density and 234Th data, including mid-point measurement date, measured activity concentration (234Thmeas, 1st measurement), supported activity concentration (238U, 2nd measurement where 234Theq is equal to 238U) and mean value (±standard deviation) per station, excess activity concentration (234Thxs), excess inventory and weighted least squares (WLS) regression metrics used to calculate mixing rates
