  Description:
    Abstract:
      The Fanny Shoal area is located between North Farallon Island and Cordell Bank approximately 40 miles west of San Francisco, California. The area is a very important habitat to a diverse marine community. The area lies within the Gulf of the Farallones National Marine Sanctuary (GFNMS), a site managed with a mandate of living and cultural resource protection that is administered by the National Oceanic and Atmospheric Administration (NOAA). The U.S. Geological Survey (USGS) in cooperation with the Golden Gate National Recreation Area (GGNRA) and NOAA, including, the GFNMS, and Monterey Bay National Marine Sanctuary (MBNMS), collected side -scanning sonar, and underwater video data over three cruises. The data are consolidated into a geographic information system (GIS) that will provide researchers and those involved in decision making with information that will aid in preserving the area's environment.

    Purpose:
      These data are intended for science researchers, students, policy
      makers, and the general public.  The data can be
      used with geographic information systems (GIS) software
      to display geologic and oceanographic information.

    Supplemental_Information:
      Additional information about the field activities from
      which this data set was derived are available online at

      Although this Federal Geographic Data Committee-compliant metadata
      file is intended to document the data set in nonproprietary form,
      as well as in ArcInfo format, this metadata file may include some
      ArcInfo-specific terminology.

          //Created grids and polygons from image files from Jamie Conrad.
          1. Converted all images to grids in ArcInfo using imagegrid command
          
          2. Converted grids to polygons for editing using ArcToolBox-->Conversion Tools-->From Raster-->Raster to Polygon 
          (*Note: unchecked "simplify polygons")
          
          3. Created a back layer for all other data. 
          In this data set the all data layer was set to 170 gridcode to represent mixed areas.
          
          4. Imported Granite layer from manual drawing of granite boundaries by Jamie Conrad done in Adobe Illustrator.
          
          5. Edited, cleaned, polygons for individual layers:
          cleaned nadar data
          converted gridcode to correct grid code if signature was incorrect
          	
          6. Converted all edited polygons back to grids using ArcToolBox-->Conversion Tools-->t0 Raster-->Polygon to Raster
               
          -------------------------------------------------------------------------------------------
          //Merged final grids to make one grid of all layers
          
          1. Merged all grids in Spatial Analyst tool Raster Calculator
                    -set option to Extent-->union of inputs.
                    -used the merge command in raster calculator dialogue box 
          
          -------------------------------------------------------------------------------------------
          //Filtered grid to decrease number of polygons
          
          steps:
          1. Filtered original grid using ArcToolBox-->Spatial Analyst Tools-->Generalization-->Majority Filter
          Settings:
          Number of Neighbors to Use: "4"
          Replacement Threshold: "Majority"
          
          2. Filter process wiped out some of the smaller areas of sediment in the bedrock (non-granite) region. 
          Went back to final grid before filter and copied the sediment areas within the bedrock. Copied these small mixed sediment regions to final polygon.

      Benthic habitat classification attributes: megahabitat,
      bottom induration, meso-macrohabitat, and modifiers from Green and others,
      1999.  
      CODE is a combination of the habitat attributes.
      MEGA_ID is S for Shelf.
      BOTTOM_ID is h for hard bottom, m for mixed hard and soft bottom, or
      s for soft sediment bottom
      MSO_MRC_ID are macrohabitats described in Greene and others 1999.
      MDFR_ID are modifiers to describe the texture or lithology of the seafloor 
      and appear in the code preceded by an underscore (_).
