Alginates (Australia) P/L submitted harvest returns for the seaweed Macrocystis pyrifera to the Tasmanian Lands Department as a condition of its harvesting license. The data consists of tonnage harvested from specific sites on the east coast of Tasmania, along with trip length information. While harvesting occurred from 1964-1973, site-level data is aggregated and available only for the years 1970 and 1971.
Use Cases
- Analyze historical seaweed harvesting intensity based on reported tonnage per site.
- Study spatial distribution of marine resource collection based on the 'where' information.
- Assess operational patterns of commercial harvesting based on the length of trip data.
- Model historical biomass removal from coastal ecosystems based on aggregated harvest returns.
Strengths
- Data originates from mandatory license returns submitted to a government department.
- Provides site-specific aggregation for two years (1970 and 1971).
- Includes temporal, spatial, and operational dimensions (tonnage, location, trip length).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data coverage is limited to two years despite a longer harvesting period (1964-1973).
- Row count is unknown, which may limit suitability assessment.
