    Bioturbation, the biogenic modification of sediments through particle reworking
    and burrow ventilation, is a key mediator of many important geochemical
    processes in marine systems. In situ quantification of bioturbation can be
    achieved in a myriad of ways, requiring expert knowledge, technology, and
    resources not always available, and not feasible in some settings. Where dedicated
    research programmes do not exist, a practical alternative is the adoption
    of a trait-based approach to estimate community bioturbation potential (BPc).
    This index can be calculated from inventories of species, abundance and
    biomass data (routinely available for many systems), and a functional classification
    of organism traits associated with sediment mixing (less available). Presently,
    however, there is no agreed standard categorization for the reworking
    mode and mobility of benthic species. Based on information from the literature
    and expert opinion, we provide a functional classification for 1033 benthic
    invertebrate species from the northwest European continental shelf, as a tool to
    enable the standardized calculation of BPc in the region. Future uses of this
    classification table will increase the comparability and utility of large-scale
    assessments of ecosystem processes and functioning influenced by bioturbation
    (e.g., to support legislation). The key strengths, assumptions, and limitations of
    BPc as a metric are critically reviewed, offering guidelines for its calculation and
