Description:
Abstract:
Benthic habitat polygon coverages have been created for marine reserve locations surrounding the Santa Barbara Basin. Diver, ROV and submersible video transects, bathymetry data, sedimentary samples, and sonar mapping, have been integrated to describe the geological, biological, and oceanographic aspects of habitat. Anacapa Reserve, is part of the Marine Ecological Reserves Research Program (MERRP). The U.S. Geological Survey (USGS), in a cooperative project with Sea Grant-MERRP and investigators at National Marine Fisheries Service (NMFS), the Channel Islands National Marine Sanctuary (CINMS), and National Park Service (NPS) has collected sidescan sonar and video data to produce a polygon coverage. The habitat polygons have attributes for megahabitat, bottom induration, macrohabitat (where macrohabitat observations are available), polygon area, polygon perimeter, and water depth. The habitat GIS shows rocky habitat suitable for rockfish (Sebastes sp.), abalone (Haliotis sp.), and other threatened benthic species from the shoreline out to the 100-m depth limit of the survey.
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.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Habitat polygons were hand drawn from a georeferenced sidescan sonar mosaic tiff.
Habitat attribute types are from Greene, G.H., Yoklavich, M.M., Starr, R.M., O'Connell, V.M., Wakefield, W.W., Sullivan, D.E., McRea, J.E., and Cailliet, G.M., 1999. A classification scheme for deep seafloor habitats. Oceanologica Acta, 22, 663-678.
Macrohabitat attributes assignments are limited to areas where bottom video has been collected.
Logical_Consistency_Report:
Polygon topology present. Every polygon has a label and are all polygons closed
Completeness_Report:
Macrohabitat classification is missing where video information is lacking
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Accuracy of the horizontal coordinates is on the order of 10 m based on uncertainty in position of sidescan sonar fish relative to ships gps position.

Process_Description:
//Create coast grid 1. Created polygon feature class of portion of ca coast line needed in ArcGIS by tracing the coast shape file. created: coast_poly.shp 2. Converted polygon feature class to grid using ArcMap Spatial Analyst-->convert feature to raster. created: coast_mask 
----------------------------------------------------------------------------------------
//Calculated no data where there is land 1. Created shapefile mask -create new polygon feature class in ArcCatlog -add new polygon to project -using ArcMap Editor make new polygon a rectangle around all data -in arctoolbox-->analysis tool-->overlay-->erase erase coast_poly polygon from new rectangle polygon new shapefile_erase has hole of island data -in spatial analyst-->options-->set mask-->use drop down to select newerase shapefile 2. Recalculated secru1mhabg with new mask poly by using the spatial analyst's raster calculator [secru1mhab1g] = [secru1mhabg] --> select evaluate resulting grid has a hole (no data) where land was //Set all 0 data to no data 1. Spatial analyst raster calculator divide grid by itself secru1mhab1g/secru1mhab1g where 0/0 will equal no data all other data will be equal to 1 calculation leaves you with value 1 where there was data 2. Spatial analyst raster calculator multiply new calculation by original grid: secru1mhab1g * [Calculation] (note: result is Calcultion2) so all values * 1 gives you original data 
-------------------------------------------------------------------------------------------
//Calculated new grid with cleaned near shore data (from mud to rock) 1. created update rock grid. -used gridpaint tool to paint in additional rock near shore area in rock only grid 2. Merged new rock grid with previous all hab grid in Spatial Analyst tool Raster Calculator -set option to Extent-->union of inputs. -in raster calculator dialogue box merge grids of rck and hab: [secru1mhab4g] = merge([secru_rock3 - secru_rock3],[Calculation2 ]) 3. Cleaned up painted in data outside sonar area -Convert new grid to polygon. -Use ArcToolbox Earse tool with "cookie cutter" made from entire sonar area. 
-------------------------------------------------------------------------------------------
//Filtered grid to decrease polygon total steps: 1. filtered original grid using the "low" filter default filter secru1mhab5g secru1mhab6g 2. reclassified new grid using spatial anlysis reclassification option and the following remap categories: 1 128 : 85 129 189 : 170 190 225 : 255 3. converted new floating point grid to an integer grid. secru1mhab8g = int(secru1mhab7g) 4. converted new floating integer grid to polygon shapefile using Toolbox Raster to Features: new polygon shapefile: 85,257 polygons original polygon shapefile: 171,781 polygons

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 usually S for Shelf, but may be F for basin or canyon flank. BOTTOM_ID is h for hard bottom, m for mixed hard and soft bottom, or s for soft sediment bottom MSO_MRC_ID are visual observations when sand waves (w) were observed. These 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 (_). Including; fractured (_f), differently eroded (_d), kelp (_k), and limestone (_l)
