Description:
Abstract:
These data depict surficial sediments in Massachusetts state waters mapped in the 2015 Massachusetts Ocean Management Plan. The data characterize the seabed using the Barnhardt et al. (1998) sediment classification scheme with sixteen sediment types based on four primary sediment units: rock, gravel, sand, and mud. Twelve additional two-part units represent combinations of the four primary units. The surficial sediments were mapped using new U.S. Geological Survey (USGS) interpreted seafloor sediment data, Massachusetts Department of Environmental Protection (MassDEP) wetlands sandy beach and rocky shore delineations, older USGS interpreted sediment maps, and an updated version of the Massachusetts Office of Coastal Zone Management (CZM)/Massachusetts Division of Marine Fisheries (DMF) sediment database used in the 2009 ocean plan. Since a variety of sources was used to create these data, a confidence key was developed using four data confidence levels: very high, high, medium, and low. Very high-confidence data include the new USGS sediment interpretations and MassDEP wetlands. High-confidence data consist of the older USGS sediment interpretations and Thiessen polygons derived from high-quality sediment points in the CZM/DMF sediment database. Thiessen polygons derived from medium-quality sediment points in the CZM/DMF sediment database are medium-confidence data and Thiessen polygons derived from low-quality sediment points are low-confidence data. The CZM/DMF sediment database, which was used to create the Thiessen polygons, contains a spectrum of quality, therefore CZM developed a data quality index to quantify the variability in data confidence based on sample age, sampling device, and analytical technique. For more information about the data quality index, please see the sediment resources technical work group report available on the ocean plan website (<http://www.mass.gov/eea/waste-mgnt-recycling/coasts-and-oceans/mass-ocean-plan/2009-ocean-plan-review-update.html>).
Purpose:
These data were used in the development of the 2015 Massachusetts Ocean Management Plan.
Supplemental_Information:
The Massachusetts Ocean Management Plan protects critical marine habitat and important water-dependent uses and sets standards for new ocean-based development. In response to the Oceans Act of 2008, the Executive Office of Energy and Environmental Affairs (EEA) issued the original ocean plan in December 2009. The Oceans Act requires EEA to review and update the ocean plan at least once every five years. The 2015 Massachusetts Ocean Management Plan, released on January 6, 2015, is the first formal amendment to the 2009 ocean plan. These data were produced to support the development of the 2015 ocean plan.

USGS provided a shapefile of the data shown in the interpretive map of sedimentary environments in Boston Harbor-Massachusetts Bay. The dataset was crosswalked from its native classification framework to the Barnhardt et al. (1998) scheme by USGS at CZM's request. Each polygon was assigned a sediment type by interpreting the intersecting CZM/DMF sediment database points. For those polygons with no intersecting points, the following crosswalk was used (sedimentary environment/backscatter patterns followed by Barnhardt name and code): erosion or nondeposition/isolated reflection = rock (R), erosion or nondeposition/strong backscatter = gravel with sand (Gs), sediment reworking/strong to weak backscatter patches = sand (S), and deposition/weak backscatter = mud (M). These data are one of the older USGS interpreted seafloor sediment datasets.

Attribute_Definition:
Bottom-type classification on the basis of twelve composite units that represent combinations of four end-member units (R = rock; G = gravel; S = sand; M = mud).

Barnhardt, W.A., Kelly, J.T., Dickson, S.M., Belknap, D.F., 1998. Mapping the Gulf of Maine with Side-Scan Sonar: A New Bottom-Type Classification for Complex Seafloors: Journal of Coastal Research, Vol. 14, No. 2 (Spring, 1998), pp. 646-659.

Enumerated_Domain:
Enumerated_Domain_Value: Rf
Enumerated_Domain_Value_Definition:
Rock with fine sediment (sand or mud). The dominant texture (> 50%) Rock (R) is given the upper case letter and the subordinate texture (< 50%) fine sediment (f) is given a lower case letter. CZM added this class so that analyzed seafloor bottom photos could be added to the CZM/DMF sediment database. When analyzing bottom photos, it is difficult to accurately classify sand vs. mud, so sand and mud were grouped as fine sediment.
