IMOS Zooplankton Abundance from Nine Australian Coastal Stations

Zooplankton abundance estimates from monthly sampling at nine Integrated Marine Observing System (IMOS) National Reference Stations around Australia. The dataset includes community composition, biomass, and size spectrum analysis, with data available from the Australian Ocean Data Network portal. Sampling began in 2002 at some sites, and the taxonomic resolution has evolved over time.

Use Cases

• Analyzing long-term trends in zooplankton community composition based on monthly sampling.
• Modeling biomass distribution in coastal waters based on dry weight measurements.
• Studying the size structure of plankton populations using Zooscan size spectrum analysis.
• Investigating spatial variability in plankton abundance across nine Australian coastal stations.

Strengths

• Data originates from a standardized national observing network (IMOS) with nine regular sampling stations.
• Includes three distinct analysis products: community composition, biomass, and size spectrum.
• Provides a change log to track evolving taxonomic resolution over time.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Sampling frequency is not uniform, with Esperance and Ningaloo sampled only every three months.
• Row count is unknown, which may limit suitability assessment.
