Background information and definitions
Communication and power cables, and oil and gas pipelines, can impact subtidal benthic invertebrates through physical damage and habitat loss. The burial process could be planned ahead of installation with the aim of reducing physical impacts on the seabed and on subtidal benthic invertebrates. For instance, using ploughing techniques rather than water-jetted trenching or directional drilling can be less disruptive to subtidal benthic invertebrates and promote recovery following disturbance (Kraus & Carter 2018).
