What is a Bioband?

• defined by a characteristic species assemblage
• visible from the air
• has a distinctive across-shore elevation
• occurs at certain wave exposures
• present on specific substrates

What is Biological Wave Exposure?

• determined from the observed biobands
• assigned a set of indicator species and a
  typical set of biobands
• is considered the most accurate representation
  of actual exposure

What is Habitat Class?

• summary of the biophysical characteristics of
  each unit, combining the intertidal biota and the
  geomorphology

• substrate mobility biota

Oil Residence Index Model

• based on units substrate and biological wave
  exposure

ShoreZone mapping

• regional patterns represent differences in
  distribution of habitats
• richness of descriptive attributes encourages
  innovative combinations
• regional comparisons and analyses are available
  in the Alaskan ShoreZone data
