Help assess how fish contribute to the ocean’s carbon cycle

Posted by hbenway

The role of fish and other metazoans in the Biological Carbon Pump has long been overlooked. As part of an effort to identify the processes through which fish, krill, and squid contribute to carbon sequestration — and to evaluate where and how fishing might have the largest impact — we are conducting an IPCC-style confidence assessment of current scientific understanding.

This initiative originated during the ICES Workshop WKFISHCARBON2, held last April in Copenhagen. We invite the community to share insights by completing a short survey (~15 minutes, also accessible on smartphones).

Your contribution will help strengthen our collective understanding of how metazoans support the biological carbon pump, and to identify research priorities.

Take the survey here.

A glossary of the main terms used in the survey is available here.

Please feel free to reach out with any suggestions or comments. We are very grateful for your time and contribution!
