BECS WG – Benthic Ecosystem and Carbon Synthesis

Benthic Ecosystem and Carbon Synthesis (BECS) Working Group

The BECS working group is aimed at understanding the carbon cycle and ecosystems within the land-to-ocean aquatic continuum by improving our understanding of related benthic processes and their representation in ocean and climate models. Benthic sediments (i.e. the seafloor) serve as the only long-term (century-to-millennial) sink of ocean carbon. Despite their critical role in the global carbon cycle, our understanding of coastal and global carbon dynamics is hindered by both a paucity of data and simplistic representations of seafloor biogeochemistry and ecosystems in models. This represents a key deficiency in future projections of the global carbon cycle and our quantification of the role of the benthos as a long-term carbon sink. Despite these uncertainties, many proposed carbon dioxide removal (CDR) and “blue carbon” climate mitigation strategies rely on ocean sediments as carbon sinks.

The coastal oceanography and global modeling communities currently operate in separate silos. This working group will be an important step forward to bridge the knowledge gap left by the lack of integration between coastal and global efforts. We hope to identify gaps in our understanding of key processes in benthic communities across space in the coastal ocean. We will bring together a community of observationalists and modelers to integrate knowledge on coastal and open ocean benthic fluxes and biota, and coastal water column nutrient fluxes, which can be influenced by benthic-pelagic interactions. To that end, we have the following goals:

  1. Facilitate communication and data sharing between coastal and global biogeochemical / ecosystem modelers and observationalists.
  2. Establish shared data protocols, including common definitions and variable names/units.
  3. Develop data products for model development.
  4. Develop recommendations for future directions in observations and modeling.

Introduction to Working Group and Overview of Benthic Ecosystem and Carbon Synthesis2023 March 13Cristina Schultz and Jessica Luo introduced the BECS working group in the context of past OCB efforts.

Jack Middelburg (Professor of Geosciences at Utrecht University, The Netherlands) is an international leader on ocean biogeochemical cycles, particularly sedimentary inorganic cycles and benthic ecosystems.

Would you like to deliver a talk?

The BECS Working Group is soliciting speaker applications for future webinars on topics such as:

  • Benthic biogeochemical fluxes (carbon, oxygen, and nutrients)
  • Benthic boundary layer dynamics
  • Benthic ecosystems (community ecology, ecosystem-environment interactions)
  • Organic matter transformations
  • Methods / Techniques
  • Human interactions
  • Global change
  • Syntheses

For these seminars, we are focused on the coastal and open ocean, not estuaries, and are interested primarily in observational studies (though if you have an interesting modeling study, please do not hesitate to submit.)

Each seminar should be 20-25 minutes in length, and we plan to offer two per webinar with time for discussion at the end. If you are more comfortable pre-recording your seminar and/or you would like to practice your seminar before presenting we are happy to help. Please add a note in the comment section if this is the case. We are eager to highlight the work of early career researchers and scientists and we particularly encourage those from the Global South to submit an abstract.

Get Involved

OCB BECS Working Group call for community input

To achieve the working group goals listed above, we are (1) hosting a series of broad community engagement efforts, including Town Halls, bi-monthly webinars, and sessions at major conferences. In addition, we are (2) organizing a set of smaller working group meetings to develop a set of research priority recommendations, and work together to generate data products that can inform benthic model development and model-data intercomparisons.
For the smaller working group meetings, we are soliciting comments and suggestions from the community regarding research priorities, knowledge gaps, and technological needs for improving our understanding of benthic ecosystems and benthic-pelagic coupling.

For this questionnaire, please set aside at least 10-15 minutes to answer the questions. There are a total of 3 pages to this survey, focused on general information, knowledge gaps at different scales, and processes, technologies, and observations vs. modeling. However, please feel free to answer a few or all of the questions. We are hoping to get wide community input that will inform our research priorities and recommendations.
