IMOS National Reference Station Zooplankton Abundance Around Australia

Zooplankton abundance estimates from monthly samples collected at nine National Reference Stations around the Australian coastline. The dataset includes community composition, biomass, and size spectrum analysis, with data available from 2002 onward. It is managed by the Australian Ocean Data Network as part of the Integrated Marine Observing System.

Use Cases

• Analyze long-term trends in zooplankton community composition based on taxon abundance per cubic meter.
• Model biomass changes in marine ecosystems based on dry weight measurements.
• Study size distribution patterns of zooplankton using size spectrum analysis data.
• Compare zooplankton populations across different coastal regions of Australia.

Strengths

• Time-series data collected monthly at nine stations, with some records dating back to 2002.
• Samples are analyzed for multiple metrics: community composition, biomass, and size spectrum.
• Data is made interoperable with other national and international programs through IMOS infrastructure.

Limitations

• Taxonomic resolution has changed over time, requiring users to consult change logs for validity.
• Column-level documentation is absent; field semantics must be inferred after download.
• Sampling frequency varies, with Esperance and Ningaloo stations sampled only every three months.
