Results and Conclusions
The result of this endeavor is a detailed seamless
map extending from the land into the estuary
identifying the subaqueous soil resources and soil-
landscape model at a scale of 1:12,000. Important
subaqueous soil interpretations have been
identified and will be developed, such as dredging
(sulfidic materials), SAV and shellfish habitat, and
moorings. Ancillary benefits are many and include
detailed bathymetry, submerged archeological
investigations, geomorphologic investigations, and
ecologically meaningful characterization of important shallow water habitats,
particularly necessary for eelgrass restorations. Ultimately, new partners and
stakeholders will be engaged in the National Cooperative Soil Survey efforts.

The USDA, Natural Resources Conservation
Service, a member of the National
Cooperative Soil Survey, is the lead federal
agency for the mapping and interpretations
of the nation’s soil resources. The well
established standards, techniques, and
protocols used to map and interpret the
nation’s terrestrial soil resources have been
applied to this project.
Using bathymetry data and soil descriptions
from augering, soil scientists identified
subaqueous landforms and developed a soil-
landscape model. Specific points were then
located within each soil-landscape area and
soil samples were taken using a vibracore.
The soil samples were described and sent to
the NRCS National Soil Survey Center, in
Lincoln, Nebraska, for laboratory analyses.
