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

Posted by hbenway 
· Thursday, October 30th, 2025 

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!

———————————————–

We are pleased to announce that applications are now open for new core committee members of the Early Career Scientists Network (ECSN) of the Second International Indian Ocean Expedition (IIOE-2). The ECSN provides a platform for early career researchers working on Indian Ocean science to connect, collaborate, and contribute to the broader goals of the IIOE-2. Eligibility criteria: 1. Applicants should be either a PhD student, postdoctoral researcher, or scientist with less than 10 years since obtaining their PhD or under the age of 40 (whichever comes first). 2. Applicants must be actively engaged in Indian Ocean research. If you are interested, please complete the application form attached to this e-mail and send it to ecsn.iioe@gmail.com. The deadline for submission is 24 October 2025. We encourage motivated early career scientists to apply, and kindly ask you to re-distribute this call within your network so it can reach as many eligible colleagues as possible.

NEW Report: Pathways Connecting Climate Changes to the Deep Ocean

Posted by mmaheigan 
· Thursday, August 28th, 2025 

Now published – workshop report from the Pathways Connecting Climate Changes to the Deep Ocean: Tracing physical, biogeochemical, and ecological signals from the surface to the deep sea
A joint OCB-US CLIVAR scoping workshop

This workshop will brought together observational oceanographers and modelers across physical, biogeochemical, and ecological communities to assess our understanding of pathways connecting the surface to the seafloor and to develop recommendations for improved detection and attribution of change in the global deep ocean system.

Workshop goals:

  1. Provide an updated comprehensive assessment of the deep ocean’s state and changes across disciplines, of key quantities in which these changes are expressed, and of pathways and timescales connecting the surface to the seafloor.
  2. Review existing observation and modeling tools and their adequacy for constraining, understanding, and attributing changes in the deep ocean system. Identify critical knowledge and observational data gaps and model deficiencies.
  3. Develop a collective set of recommendations for improved detection and attribution of change in the global deep ocean system, with a focus on better serving and supporting deep ocean science across disciplines.
  4. Build an interdisciplinary network of ocean modelers and observers across disciplines. Our aim is to open communication channels and facilitate collaborative exchange of data, knowledge, and tools across communities.
