Macrocystis Pyrifera Harvest Tonnages on Tasmania's East Coast, 1970-71

Tasmania's east coast saw commercial harvesting of the seaweed Macrocystis pyrifera under license. The dataset contains harvest returns, likely including tonnage, location, date, and trip length, submitted by Alginates (Australia) P/L to the Tasmanian Lands Department. Data for individual sites is summed for the two-year period of 1970 and 1971.

Use Cases

• Analyzing historical seaweed harvest patterns based on location and tonnage data.
• Studying the spatial distribution of licensed marine resource extraction based on site-specific harvest returns.
• Investigating the relationship between harvest duration and yield based on the length of trip information.
• Assessing the scale of a specific company's commercial seaweed operation over a defined two-year period.

Strengths

• Data is tied to a specific commercial license and regulatory reporting requirement, providing a formal record.
• Covers a defined two-year period (1970-71) for which site-level data is available.
• Spatial context is provided for the harvest activity (east coast of Tasmania).

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, covering only two years of a longer harvesting period (1964-1973).
