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. 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.
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.
Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
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.

Habitat polygons were hand drawn from a georefereced 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.
Polygon topology present. Every polygon has a label and are all polygons
closed.
Macrohabitat classification is missing where video information is lacking.
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.

Attributes 5-9 are 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 is based on visual observations of kelp (k), sand waves (w)
and other macrohabitats described in Greene and others 1999.
MDFR_ID are modifiers to describe the texture or lithology of the seafloor
such as f for fractured.
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.
