NESP MaC Project 3.6 provides spatial data on seagrass extent, species composition, and ecological value around the Furneaux Islands, Tasmania. The project, led by IMAS and Deakin University in partnership with the Tasmanian Aboriginal Centre, used high-resolution satellite remote sensing and field surveys from 2023 to 2025. Outputs include maps of seagrass beds down to 30 meters depth, validated with video observations and rhizome coring.
Use Cases
- Mapping seagrass extent and species composition based on satellite remote sensing and field validation.
- Assessing blue carbon storage potential based on rhizome core samples.
- Supporting Indigenous-led monitoring of the proposed Tayaritja Sea Country Indigenous Protected Area based on the developed standards and datasets.
- Analyzing genetic connectivity and population structure of seagrass meadows based on collected rhizome samples.
Strengths
- Project used high-resolution satellite remote sensing to map seagrass down to approximately 30 meters depth.
- Data collection was conducted in partnership with the Tasmanian Aboriginal Centre, incorporating Indigenous knowledge and management goals.
- Outputs are classified using the Seamap Australia National Benthic Habitat Classification Scheme, suggesting a standardized approach.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
