Wetland Sediment Core Data

Since 2014, over 30 coastal wetland sediment cores of up to 1 meter in length have been collected across saltmarsh and mangrove ecosystems in the continental U.S. by USGS Woods Hole Coastal and Marine Science Center’s (WHCMSC) staff led by M. Eagle. Extensive measurements of radioisotopes and elemental concentrations have resultied in cores with high resolution age-models and associated carbon and vertical accretion rates. Such data are used for a variety of purposes, including: 1) wetland carbon stock assessment, 2) soil accretion rates to validate wetland models and inform resilience to sea-level rise and 3) environmental records of coastal change.
