Alginates (Australia) P/L submitted harvest returns for the seaweed Macrocystis pyrifera as a condition of their Tasmanian license. The data, aggregated by site, covers the two years 1970-71, though the company harvested from 1964-1973. The Australian Ocean Data Network hosts this record of tonnage, location, and trip duration.
Use Cases

Strengths
- Data covers a specific two-year period (1970-71) for detailed site-level analysis
