New Review Published: Deep-Sea Ecosystems of the North Atlantic Ocean
Reviewing 18 pelagic and benthic ecosystems across the North Atlantic
A new review paper has been published examining deep-sea ecosystems across the North Atlantic Ocean:
Deep-sea ecosystems of the North Atlantic Ocean: discovery, status, function and future challenges.
The review synthesises existing scientific knowledge of deep-sea ecosystems across the North Atlantic basin, bringing together research from multiple regions and disciplines to assess current understanding and identify remaining gaps.
Scope of the Review
The paper examines 18 pelagic and benthic deep-sea ecosystem types, spanning both water-column and seafloor environments. Geographic coverage includes the Caribbean Sea, the Gulf of Mexico, and the North Atlantic from low to high latitudes.
As described by the authors, the review addresses ecosystem “discovery, status, function and future challenges” across the basin.
Key elements covered include:
The distribution and characteristics of deep-sea ecosystems in the North Atlantic
The history of exploration and scientific discovery in the region
Identification of spatial and taxonomic knowledge gaps, including areas that remain poorly studied
A synthesis of reported human impacts, including fishing, shipping, mineral extraction, climate change, and pollution
Discussion of future research challenges and priorities, including ecosystem distribution, connectivity, function, and ecosystem services
Contribution to Deep-Sea Science
By consolidating a wide body of existing literature, the review provides a regional synthesis of deep-sea ecosystem knowledge in the North Atlantic. The authors highlight that research effort has been uneven across the basin and that long-term and spatially comprehensive data remain limited for many ecosystems.
The paper provides a reference point for future studies by summarising what is currently known and clearly outlining where further research is required.
Relevance to Challenger 150
The review aligns with Challenger 150’s objective to support coordination and knowledge-sharing in deep-sea research. Comprehensive syntheses such as this help clarify the current state of understanding across regions and ecosystems and support discussion of shared research priorities within the scientific community.
Challenger 150 welcomes the publication of this review and recognises the collaborative effort involved in bringing together decades of research across the North Atlantic.
