Tasmanian Seaweed Harvest Tonnages for Macrocystis pyrifera, 1970-71

1970-71 harvest tonnage data for the seaweed species Macrocystis pyrifera, collected from the east coast of Tasmania. The data was submitted by Alginates (Australia) P/L as a condition of its commercial harvesting license and is aggregated by site for the two-year period. The dataset is hosted by the Australian Ocean Data Network.

Use Cases

• Analyzing historical seaweed harvest patterns based on tonnage and location data.
• Studying commercial marine licensing compliance based on reported harvest returns.
• Modeling historical resource pressure on Macrocystis pyrifera populations based on site-specific harvest data.

Strengths

• Data covers a specific two-year period (1970-71) for detailed temporal analysis.
• Information is aggregated by individual harvest sites, providing spatial granularity.
• Data originates from mandatory commercial license returns, suggesting a formal reporting mechanism.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to data_gov_au, as only two years of site-level data are available.
