Inter-and Intra-Annual Sediment Dynamics in Two Tidal Marshes: Deposition, Accretion, and Vegetation Data (ver. 2.0, June 2025)
The U.S. Geological Survey, Western Ecological Research Center collected sediment and accretion data at two marshes in San Francisco Bay, California over the course of 15 months, capturing a full hydrological year and two spring-summer transitions. Sediment traps were deployed monthly in triplicate along transects of increasing distance from sediment sources (i.e., channels) to capture meter-scale spatial variability in sediment deposition and paired with feldspar marker horizons (MH) to measure long-term accretion. These data include sediment trap and MH plot locations, calculated sediment fluxes (g/m2/day) at each station by deployment period, annual accretion rates (mm/yr), and covariates associated with sediment deposition and accretion including vegetation and elevation. This project aimed to investigate variation in sediment deposition across spatiotemporal scales to provide insights into sediment delivery and marsh resilience to sea-level rise.
