Tasmanian Giant Kelp Harvest Tonnages by Site for 1970-71

Tasmania's east coast harvest data for the giant kelp species Macrocystis pyrifera, collected by Alginates (Australia) P/L as a license condition. The data consists of tonnage harvested per site, location, date, and trip length, summed for individual sites across the two years 1970-71. It was aggregated by the Australian Ocean Data Network.

Use Cases

• Analyzing historical spatial distribution of kelp harvesting based on the 'where' data mentioned in the description.
• Modeling seasonal or temporal harvest patterns based on the 'when' data mentioned in the description.
• Assessing operational efficiency or effort based on the 'length of trip' data mentioned in the description.
• Studying the historical commercial pressure on a specific marine species (Macrocystis pyrifera) in a defined region.

Strengths

• Data is sourced from mandatory license returns, suggesting a formal reporting mechanism.
• Provides site-specific aggregation for the years 1970-71, offering spatial granularity.
• Covers a historically significant period for the Tasmanian kelp industry.

Limitations

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