Abstract:
These data represent the hard/complex seafloor special, sensitive, or unique (SSU) resource mapped in the 2015 Massachusetts Ocean Management Plan. Hard seafloor is seabed characterized by exposed bedrock or concentrations of boulder, cobble, or other similar hard bottom distinguished from surrounding unconsolidated sediments. Complex seafloor is a morphologically rugged seafloor characterized by high variability in bathymetric aspect and gradient. Biogenic reefs and man-made structures, such as artificial reefs, shipwrecks, or other functionally equivalent structures, may provide additional suitable substrate for the development of hard bottom biological communities. Hard/complex seafloor is seabed characterized singly or by any combination of hard seafloor, complex seafloor, artificial reefs, biogenic reefs, or shipwrecks and obstructions to navigation. For the 2015 ocean plan, hard/complex seafloor was mapped using updated surficial seafloor sediment data and the same complex seafloor data used in the 2009 ocean plan. The locations of artificial reefs, biogenic reefs, and shipwrecks and obstructions were added to the 2015 SSU resource area.
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.

Source_Contribution:
Source information used in support of the development of the dataset. Crepidula reefs and worm reefs were mapped as biogenic reefs using information from analyzed seafloor photographs. Over 10,000 images of the seafloor have been obtained from the CZM-U.S. Geological Survey Seafloor Mapping Cooperative and from surveys conducted by CZM and partners on the Ocean Survey Vessel Bold. CZM has classified the biological information in these photos according to a modified version of the Coastal and Marine Ecological Classification Standard, specifically the benthic biotic component (Federal Geographic Data Committee 2012). This dataset represents the locations of photos where the dominant biotic group was classified as a gastropod reef or a worm reef.

Source_Contribution:
Source information used in support of the development of the dataset. Shipwrecks and obstructions to navigation were mapped using the Board of Underwater Archaeological Resources' (BUAR) recreational shipwreck sites designated as "exempted sites" (member sites of the National Oceanic and Atmospheric Administration [NOAA]/U.S. Department of the Interior [DOI] National System of Marine Protected Areas) and NOAA's Automated Wreck and Obstruction Information System (AWOIS). AWOIS is a catalog of reported wrecks and obstructions that are considered navigational hazards in coastal U.S. waters. These data are not a comprehensive inventory of wrecks.
Process_Step:
Process_Description:
1. Hard seafloor was mapped by extracting areas characterized as rock, rock with gravel, rock with sand, or rock with mud from the surficial sediment in Massachusetts state waters dataset. Surficial sediment was mapped by collating data sources such that high-quality data mask lower quality data in the following order, highest first: 1) new U.S. Geological Survey (USGS) interpreted seabed sediment (Pendleton et al. 2013 and unpublished data in review), 2) Massachusetts Department of Environmental Protection wetlands, 3) older USGS sediment interpretations (Poppe et al. 2007; Poppe et al. 2006; Knebel and Circe 1995; Rendigs and Knebel 2002), and 4) interpolated Thiessen polygons derived from the CZM/DMF sediment database. (Thiessen polygons proportionally divide and distribute a point coverage into regions known as Thiessen or Voronoi polygons. Each Thiessen polygon defines an area of influence around its sample point, so that any location inside the polygon is closer to that point than any of the other sample points.) The 2013-present USGS interpreted surficial sediment data and the CZM/DMF sediment database were classified using the Barnhardt et al. (1998) scheme while all other data were crosswalked from their native sediment classification framework to Barnhardt. Barnhardt is based on four primary sediment units: rock (R), gravel (G), sand (S), and mud (M). Twelve additional two-part units represent combinations of the four primary units, where the majority texture is given an upper case letter and the next most common texture is given a lower case letter. Sediment grain sizes follow the Wentworth (1922) scale. Rock is characterized as cobble and larger (>64 mm), so R, Rg, Rs, and Rm are all classified as hard bottom.

2. Complex seafloor was calculated on bathymetry data using an algorithm developed by Sappington et al. (2007) that directly measures seafloor complexity. The unitless value can range from 0 (no seabed complexity) to 1 (complete seabed complexity).
