Data quality info

Hierarchy level
Dataset

Report

Measure description
Varies from ± 10 to ± 100 metres. Largest variation mostly dependent on distances between sites.

Report

Measure description
Contains biomass attributes which refer to a visual estimate of above ground seagrass biomass (grams dry weight) of seagrass in a square metre. Information finalised.

Report

Measure description
All habitats examined between 2002 and 2014 are represented. Seagrass can change seasonally and between years. Users should ensure they make appropriate enquiries to determine whether new information is available on the particular subject matter.

Resource lineage

Statement
Derived from visual assessment of the intertidal seabed by observers using helicopter, boat, free diving, grabs, sled, video and walking.
