    Surface Water - Benthic Macroinvertebrate Results

    Metadata Updated: January 23, 2026

    Data collected for marine benthic infauna, freshwater benthic macroinvertebrate (BMI), algae, bacteria and diatom taxonomic analyses, from the California Environmental Data Exchange Network (CEDEN). Note bacteria single species concentrations are stored within the chemistry template, whereas abundance bacteria are stored within this set. Each record represents a result from a specific event location for a single organism in a single sample.

    The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result.

    Zip files are provided for bulk data downloads (in csv or parquet file format), and developers can use the API associated with the "CEDEN Benthic Data" (csv) resource to access the data.

    Users who want to manually download more specific subsets of the data can also use the CEDEN Query Tool, which provides access to the same data presented here, but allows for interactive data filtering.
