Attributes 6-8 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.
