Kelp Harvest Tonnage from Tasmanian East Coast Sites, 1970-71

Harvest returns for Macrocystis pyrifera (kelp) were submitted by Alginates (Australia) P/L as a license condition to the Tasmanian Lands Department. The data, summed for individual sites, covers the two-year period of 1970-71 and includes tonnage, location, date, and trip length. While the company harvested from 1964-1973, site-specific data is only available for these two years.

Use Cases

• Analyzing historical kelp harvest intensity based on reported tonnage and location.
• Studying the spatial distribution of marine resource extraction based on the 'where' data.
• Investigating seasonal or temporal patterns in harvesting activity based on the 'when' data.
• Assessing operational characteristics of historical fisheries based on trip length information.

Strengths

• Data covers a specific two-year period (1970-71) for detailed temporal analysis.
• Includes multiple reported dimensions: tonnage, location, date, and trip length.
• Sourced from official license-mandated returns to the Tasmanian Lands Department.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to two years (1970-71) despite a longer harvesting period (1964-1973).
• Row count is unknown, which may limit suitability assessment.
