Description:
Abstract:
These data represent the concentrated commerce traffic concentrations of water-dependent use area mapped in the 2015 Massachusetts Ocean Management Plan. This layer was created using Automatic Identification System (AIS) data from 2011-2012. AIS is a navigation safety communications system that transmits information about a vessel, including its identity, ship type, and position, to shore stations and other ships. Raw AIS data from 2011 and 2012 were processed by the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center (CSC) to create vessel tracklines. Using the tracklines produced by NOAA CSC, the Massachusetts Office of Coastal Zone Management (CZM) created a dataset of vessel density and extracted concentrated vessel density to map the concentrations of water-dependent use 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.

Process_Description:
5. Ran the Line Density tool in ArcGIS to calculate the line density of the 2011 and 2012 tracklines that fall within a 177-meter search radius of each 250 x 250-m grid cell in the North Atlantic. The 250 x 250-m cell size was selected to be consistent with the grid used in the 2009 ocean plan. The radius was selected by calculating the radius of the smallest circle that would completely contain a grid cell. In other words, the 177-m search radius was chosen to match the length of half the diagonal of a grid cell (rounded to the nearest meter).

Process_Description:
6. Reclassified the vessel density raster into two classes: 1) ≤360 km/km^2 and 2) >360 km/km^2. To map concentrated commerce traffic, CZM followed the example of the 2009 ocean plan and used an equivalent class break of 50 vessels per year per grid cell (i.e., 100 vessels per grid cell since two years of data were used). Since these data represent vessel density based on the length of tracklines, not counts of vessels, an equivalent to the 100 vessels class break was calculated using length. As a conservative estimate, 354 meters, which is the length of the diameter of the circle used to calculate the line density, was used as an approximation of one vessel. Therefore, a class break of 50 vessels per year per grid cell is approximately equal to 360 km/km^2 of trackline density for two years of data using the following equation: (50 vessels * 0.354 km [1 vessel's trackline length] * 2 years) / (π * 0.177^2 km [area of circle]).
