Name: Northeast Salt Marsh Mineral Material Density, gM/cm^3

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Raster-based models of Northeast US salt marsh soil properties were created as part of a collaborative soil science project by scientists at the USDA-NRCS and University of Massachusetts Amherst. The dataset includes four raster layers that can be used to calculate blue carbon stocks. When paired with estimates of vertical accumulation rates, these datasets could also be used to estimate blue carbon sequestration or mineral sediment demand of tidal marshes. <br/><br/> 1. Northeast Saltmarsh Soil Organic Matter, percent<br/> 2. Northeast Saltmarsh Soil Dry Bulk Density, g cm-3<br/> 3. Northeast Saltmarsh Soil Carbon Density, gC cm-3<br/> 4. Northeast Saltmarsh Soil Mineral Material Density, gM cm-3<br/> <br/> A total of 400 10-cm deep core samples were collected across 19 tidal marsh sites from Maine to New York. Data from these samples were used to calibrate a remote sensing-based model to predict soil characteristics and derive the four layers. Full model development will be discussed in Teng et al. (in review), and error and applications of the model described in Yellen et al. (in review). See the <a href="https://www.northeastoceandata.org/files/metadata/Themes/Habitat/NETidalMarsh_BlueCarbon.pdf" target="_blank">metadata</a> for a brief description of the model.
