Alginates (Australia) P/L submitted harvest returns for Macrocystis pyrifera to the Tasmanian Lands Department as a condition of their harvesting license. The data consists of tonnage harvested from specific sites, including location, timing, and trip length. While harvesting occurred from 1964-1973, site-specific data is only available for the years 1970-71, summed for individual sites.
Use Cases
- Analyze historical seaweed harvest intensity based on reported tonnage per site.
- Map the spatial distribution of commercial algae harvesting based on location data.
- Study seasonal or temporal patterns in harvest activity based on trip timing data.
- Assess the scale of historical marine resource extraction for a specific company and region.
Strengths
- Data originates from official harvest returns submitted to a government department.
- Covers a specific two-year period (1970-71) with site-level aggregation.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect temporal bias, as it only covers two years of a longer harvesting period.
