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.

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.

NOAA created the National Centers for Environmental Information (NCEI) by merging
NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC),
and National Oceanographic Data Center (NODC), including the National Coastal Data
Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations
Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
