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...

Product Description: This dataset provides maps of peak biomass carbon stock (C) in gC/m2 and net primary productivity (NPP) in gC/m2/yr of coastal herbaceous wetlands at a resolution of 30 m across the conterminous United States (CONUS) for 2015. Aboveground, belowground, and total peak biomass C and NPP are provided for tidal herbaceous wetlands. Data is presented for 1. all herbaceous/emergent marshes, 2. palustrine emergent marshes and 3. estuarine emergent marshes. Background: Spatial assessments of greenhouse gas emissions and carbon sequestration in natural ecosystems are necessary to develop climate mitigation strategies. Regional and national-level assessments of carbon sequestration require high-resolution...

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...

This data set includes a variety of bulk organic carbon, lignin-phenol biomarker, and sedimentation rate data from a set of sites in the Blackwater Marsh in Chesapeake Bay. At each site, a short core was taken, and all data is organized according to depth below the marsh surface. Data includes: Bulk %OC, bulk %N, atomic carbon:nitrogen ratios, stable carbon isotopes (d13C) Lignin-phenol biomarker parameters, including 8, Ad:Alv, C:V, S:V, and the individual concentrations of each lignin-phenol (in lambda units, or mg per 100 mg OC). Pb-210 and Cs-137 activities Sediment bulk densities In addition to the sediment core data, we are also including d13C values from vegetation samples collected from each of the marsh...

Blue carbon storage in coastal vegetated habitats is an important component of the global carbon cycle. In 2018, shallow sediment cores were collected in five USGS study marshes located in Humboldt Bay, CA. The cores were collected within 2 m of the marsh edge to characterize carbon storage in areas susceptible to marsh edge erosion Two sediment cores were collected in each of the five study marshes (Mad River, Manila, Jacoby, White, Hookton) using an Ejkelkamp peat sampler (52 mm diameter). The sampler was pounded in the sediments with a heavy plastic mallet. This method produces little to no compaction because once inserted, the corer is rotated 180°, and a sample is collected adjacent to where it was driven into...
