Count Component Title Abstract
1 Massachusetts Division of Marine Fisheries SED Dataset 2_17_11 This GIS data layer represents point coverage of seafloor sediment size and composition in Massachusetts territorial waters. The data were created by aggregating available sediment point data collected from the United States Geological Survey's (USGS) usSEABED, version 1.0, U.S. Geological Survey Data Series 118 (Reid 2005), the Massachusetts Water Resources Authority, the Massachusetts Division of Marine Fisheries, and the United States Environmental Protection Agency. Sediment data were collected between 1884 to 2008 from a variety of published and unpublished sediment texture and other geologic data. As such, the data has a variety of different horizontal accuracies and sampling and analysis methodologies. The dataset includes relative data quality for each point. More information regarding the compiled data sources and data quality assessment is available in Ford, K.H. and S.E. Voss. 2010. Seafloor sediment composition in Massachusetts determined using point data.

      1 The multiple datasets were compiled and then clipped to encompass the area of Massachusetts territorial waters including Nantucket Sound and a 10km buffer. Overlapping data points were checked to see if they had different dataset keys, different grain size values, different dates of sampling, or had other variables that indicated redundant samples. If the samples differed in any way such that a conclusive determination of redundancy could not be made, the samples were kept (because of the possibility that some samples were taken in the same place). Samples that were found on land were manually identified and removed. Photographic data from the DMF Lobster Project were normalized to 100% total grain size. Substrate type percentages were used to create gravel-sand-mud classifications using Folk (1954) and Shepard/Schlee codes (see Hastings, Poppe, and Hathaway, 2000. Chapter 2 in USGS East-coast sediment analysis, USGS OFR 00-358). The SEDCLASS tool was not utilized; the classifications were done with a visual basic macro within Excel. The reason there are two Folk and Shepard classifications is 2-fold: 1) We could not repeat the Folk classification results that were in usSEABED, mostly because it appears that the %Gravel values were concatenated or rounded to the nearest whole number. Therefore, the "slightly gravelly" category could not be repeated (0.1% to 5% gravel). 2) We used the Gravel-Sand-Mud ternary diagrams, rather than trying to nest the Sand-Silt Clay ternary diagrams into the Gravel-Sand-Mud diagram. The Shepard/Schlee classification approach nests well, but in many datasets we don't have reliable sand-silt-clay information. The Folk classification does not appear to be designed for nesting.
      1 The native coordinate system for the dataset is the geographic decimal degree coordinate system, North American Datum 1983 (NAD83). Corpscon 6.0.1 was used to convert to the Massachusetts State Plane Coordinate System, Mainland Zone (Fipszone 2001), meters. www.tec.army.mil
      1 The Excel spreadsheet was utilized to create a point shapefile in ArcGIS 9.3 using Add X,Y Data tool and selecting the Easting and Northing columns. All attributes were then exported to a point shapefile using the Export Data tool.
