The summer 2007 OCB Science Workshop was held July 23-26, 2007. This workshop sought to recognize new research opportunities at the interface between traditional disciplines. Participants were encouraged to “think outside the box” of their own immediate research communities and communicate with scientists in other disciplines.

1. Workshop Themes
This workshop focused on three primary interdisciplinary themes:
The interplay between biotic structure and biogeochemical cycles
Speakers explicitly address the two-way interactions between the structure and organization of biotic communities and the rates and pathways of elemental cycling in the ocean.
Changing Ocean Biogeochemistry: The Prediction Challenge
This session sought to stimulate discussion regarding predictions of future change in ocean biogeochemistry. Ocean acidification and ocean carbon storage were the foci for the breakout sessions.
Cross-boundary fluxes in the coastal ocean
This session addressed fluxes between the land margin-coastal ocean interface and the ocean-atmosphere interface.
Each afternoon, breakout groups gathered to further identify research opportunities on these themes. The purpose of the breakout groups was not to identify all research priorities of OCB, but to amplify research opportunities on the subselection of OCB topics highlighted for the 2007 workshop. Open forum breakout groups were held on the last morning of the conference to address other issues of interest to participants.
Posters were invited on the three themes above, as well as on other aspects of ocean biogeochemical research.

Breakout discussion questions:
1. What are the key unknowns in this area?
2. What observations and/or modelling studies are needed to improve our understanding?
3. How reliable are current predictions? What are the major barriers to prediction?
4. What information does the scientific community need to provide for policy discussions? What questions do we need to be prepared for?
5. How can OCB best contribute to progress in this area?
- Biotic Structure and Biogeochemical Cycles
- Predicting Future Carbon Storage
- Food Webs
- Margin Fluxes with Large Land/Ocean Exchange
- Ocean Acidification
- Coastal Carbon and Ecology
