Abstract

• Despite improvements in understanding abyssal biodiversity, knowledge gaps in abyssal evolution and biogeography, connectivity and biotic responses to natural temporal and anthropogenic change remain. The incomplete knowledge of abyssal systems reflects major challenges in sampling this vast and remote area.
• Abyssal environments support processes underlying deep-sea and global ecosystem functioning and link closely to surface production and pelagic processes.
• Marine carbon dioxide (CO2) removal and ocean-based carbon interventions may affect abyssal systems directly if deployed on the seafloor or affect pelagic processes that could indirectly result in changes in abyssal ecosystem function.
• Despite knowledge improvements on abyssal biodiversity linked to deep-sea mineral exploration, full assessment of impacts of exploitation on abyssal ecosystems requires further scientific research.
