This data release includes monitoring data collected by the U.S. Geological Survey (USGS) Humboldt Bay Water Quality and Salt Marsh Monitoring Project. The datasets include continuous water levels collected at a 6-minute timestep collected in two study marshes (Mad River and Hookton). Surface deposition, elevation changes and carbon storage (in marsh edge environments) measured in five USGS study marshes (Mad River, Manila, Jacoby, White and Hookton). The monitoring data presented in this data release represent fundamental datasets needed to manage blue carbon stocks, assess marsh vulnerability, inform SLR adaptation planning, and build coastal resiliency to climate change in Humboldt Bay, CA Additional documentaton...
Elevation change and surface deposition are important drivers of salt marsh ecological processes and represent two of the fundamental variables for determining marsh resilience to sea-level rise. Surface Elevation Tables with Marker Horizons (SET-MH) were used to measure plot-scale elevation change (SETs) and surface deposition (MHs) in five USGS study marshes located in Humboldt Bay, CA. SET-MHs were installed in 2014 (Mad River marsh and Manila marsh) and in 2015 (Jacoby marsh, White marsh, and Hookton marsh) and were measured during quarterly site visits. The SET-MH network includes two SETs and six MHs in each of the five study marshes. Measuring elevation change at the two SETs in each study marsh involves...
The U.S. Geological Survey, Western Ecological Research Center collected sediment and accretion data at a wave-exposed tidal salt marsh in South San Francisco Bay, California. Sediment traps and feldspar marker horizons (MH) were deployed along transects of increasing distance from the sediment source, at primary, secondary and tertiary marsh channels/bay. Data were collected bi-monthly over two month periods in summer 2021 and winter 2021/2022. Included here are trap and MH plot locations, calculated sediment fluxes at each station by deployment period, annual accretion rates, and covariates associated with sediment deposition and accretion including vegetation structure and elevation. This project aimed to assess...
