Australian Phytoplankton Abundance and Biovolume from Nine Coastal Stations

Monthly phytoplankton samples from nine Australian coastal reference stations provide community composition, abundance in cells per liter, and biovolume in cubic micrometers per liter. The Plankton National Reference Station within the Integrated Marine Observing System (IMOS) collects integrated water samples at 10-meter depth intervals, preserved in Lugol's solution. Data is managed by the CSIRO Marlin Data Catalogue and made available via the Australian Ocean Data Network (AODN) portal.

Use Cases

• Analyze phytoplankton community composition and abundance (cells/L) trends across nine Australian coastal stations for ecological monitoring.
• Model relationships between phytoplankton biovolume (um3/L) and environmental variables from co-located water sampling programs.
• Track changes in taxonomic resolution over time using the provided change log tables to ensure data validity for time-series analysis.

Strengths

• Data originates from a systematic national program with monthly sampling at nine fixed stations around Australia.
• Includes two core biological metrics: abundance (cells/L) and biovolume (um3/L) for phytoplankton community analysis.
• Planned for interoperability with other national and international marine observing programs through IMOS infrastructure.

Limitations

• Taxonomic resolution has changed over time, requiring careful use of included change log tables for consistent analysis.
• Classification fields (e.g., genus, species) may be blank if identification was only possible to a higher taxonomic level.
• Sampling frequency is reduced to three-monthly at the Esperance and Ningaloo stations compared to monthly elsewhere.
