Working group towards a better understanding of fish contribution to carbon flux - PI: Grace Saba (Rutgers University)
Objective: We will begin to tackle the issue of the carbon flux contribution from upper trophic levels. This contribution is completely ignored in present-day carbon budgets and is likely significant due to high abundances of fish in certain regions (i.e., coastal zones, mesopelagic) and previous documentation of high fish contribution to total carbon flux. Products of the working group meeting will include: 1) a review paper on fish carbon flux with a concluding section on research priorities identified during the meeting; and 2) a science plan for submission of collaborative proposals to funding agencies to expand our knowledge of fish contribution to carbon flux, ranging from single-species laboratory experiments to incorporating fish carbon estimates into regional and global biogeochemical models.
- Synthesize the existing research on fish carbon flux
- Recognize challenges in measuring fish carbon flux and discuss approaches to resolve them
- Develop research priorities to fill in the large gaps in understanding fish carbon flux
- Identify opportunities to obtain resources needed to move this research forward
