Torres Strait Seagrass Mapping Consolidation
Between 2002 and 2014 Torres Strait was surveyed to assess seagrass presence and absence, and biomass (grams dry weight per m2) in the intertidal and subtidal zone.

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.
