Tasmanian Seaweed Harvest Tonnages for 1970-71

Tasmania's east coast harvest data for the seaweed species Macrocystis pyrifera, collected by Alginates (Australia) P/L as a condition of its operating license. The data covers the years 1970-71, with tonnage summed by individual harvest site. Harvest returns were lodged with the Tasmanian Lands Department and detail what was harvested, where, when, and the length of the trip.

Use Cases

• Analyze historical seaweed harvest intensity based on reported tonnage and location data.
• Study the spatial distribution of commercial kelp harvesting based on the 'where' data mentioned in the description.
• Model historical fishing trip efficiency based on the reported tonnage and trip length data.
• Assess the temporal pattern of harvest activity for the 1970-71 period mentioned in the description.

Strengths

• Data is site-specific for the years 1970-71, providing spatial granularity.
• Data collection was mandated by a licensing agreement, suggesting a formal reporting process.

Limitations

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