Theme Session H - Impacts of human activities and pressures on seafloor ecosystems: past, present and future

International Council for the Exploration of the Sea (ICES) 2024
Bruno Ibanez‐Erquiaga

Summary

This ICES conference session compiled abstracts on the impacts of human activities on seafloor ecosystems, including contributions on microplastic pollution of benthic habitats. The session addressed both past and present pressures and future trajectories for seafloor ecosystem health.
