The Substratum Origin can be paired with the Substratum Component to give 8 total levels describing the non-living component of the seabed habitat. The Substratum Origin is a nested hierarchy describing the geologic origin of each Substratum Component.
Floating level
The Substratum Origin is a ‘floating’ classifier nested within each Substratum Component class and can be applied at any level.
Unknown, or Not Assessed
An Unknown, or Not Assessed classification can be applied at any level within the hierarchy.
