Subtidal low energy over unknown substrate in very deep water

Short description

Low energy substrates in very deep water (>30m depth).

Disclaimer: Ecosystem type descriptions are based on biophysical attributes identified in Central Queensland through expert advice and supported by scientific literature. Not all ecosystem types are mapped based on current inventory, and many of the ecosystems described here may also occur in other parts of Queensland.

Long description

Low energy substrates where energy is known but Consolidation, Sediment texture and Structural macrobiota are unknown. Typically habitats away from high energy beaches and creek/river mouths in greater than 30 metres.

Special values

Diagnostic attributes:

Inundation ‘Subtidal’

Benthic depth ‘Very deep (>30m)

Energy magnitude (wave) ‘Low’, ‘Very low’

Consolidation 'Unknown'

Structural macrobiota 'Unknown'

Sediment texture 'Unknown'

Substrate composition 'Unknown'


The Naturalness qualifier may be relevant as these areas may be subject to trawling.


This type was created to deal with very deep areas where there was no mapping of either consolidation, sediment texture or biota. Likely to be outside channels on gentle slopes or flats.


May not exist as a type in this typology version based on available information, which is restricted to wave energy. Application of the Energy source attribute in a typology combining both wave and current energy datasets to produce a dataset reflecting seabed stress would result in a mappable type if an extra attribute was used (i.e. Consolidation) and this was used to split unconsolidated types. Consider Terrain morphology if bathymetry is sufficiently high resolution.
