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 Sediment data were collected between 1884 to 2008 from a variety of published and unpublished sediment texture and other geologic data.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. Massachusetts Division of Marine Fisheries Technical Report, TR-45. 21pp. http://www.mass.gov/dfwele/dmf/publications/tr_45.pdf These data were compiled for the creation of surficial sediment maps. These spatial data were compiled by the Massachusetts Division of Marine Fisheries. underDevelopment Kathryn Ford & Steven Voss Massachusetts Division of Marine Fisheries Fisheries Habitat Technician 508-990-2860 508-990-0449 1213 Purchase St. 3rd Floor New Bedford MA 02740 USA steven.voss@state.ma.us 0900 to 1700 weekdays pointOfContact Carla J.

Users of the data should use their own criteria for assessing the accuracy of the locations." Other datasets included in this compilation that were collected within the past 10 years have a horizontal accuracy better than 30 meters. Horizontal accuracy varies based on the type of positioning equipment used in each survey contained in this compilation. 2000 Vertical Positional Accuracy Vertical accuracy was not assessed Vertical accuracy was not assessed Phi values less than -6 are not included in the usSEABED data. Additional datasets are known to exist that have not yet been included in this compilation. Phi values less than -6 are not included in the usSEABED data. Additional datasets are known to exist that have not yet been included in this compilation. 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). Photographic data from the DMF Lobster Project were normalized to 100% total grain size. Duplicate points exist and samples with less than and greater than 100% total grain size exist. Samples that were found on land were manually identified and removed. Lineage prior to transfer to NGDC is given below Received data from source 2011-04-13T00:00:00 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. 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 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.
