  1. THE GLOBEC GOALTo advance our understanding of the structure and functioning of the global ocean ecosystem, its major subsystems, and its response to physical forcing so that a capability can be developed to forecast the responses of the marine ecosystem to global change.

Cod catches have followed environmental trends in recent decades. Has fishing limited the capacity of cod to respond to favourable environments?

  4. REGIONAL PROGRAMMES Climate Change and Carrying Capacity (PICES-CCCC) This activity develops a theoretical and mathematical framework which extends the concept of carrying capacity into the multi-species ecosystem domain. It addresses how climate change affects ecosystem structure and the productivity of key biological species at all trophic levels in the North Pacific. 1.0 Shrimp Cod/ Pollock 0.6 Flatfish 0.2 Other 1971 1998 1962 1953 1989 1980 The community structure of the North Pacific has changed over the last decades. How is this affecting the functioning of the system?

Antarctic krill has peaks of abundance on “good-ice years”. How do climate fluctuations (and thus ice cover) affect krill and its predators?

SPACC will involve process studies, based on comparisons of standard measurements from different ecosystems, and retrospective studies built around palaeoecological and genetic data. Pelagic fish globally seem to fluctuate in synchrony. What drives this patterns?

  8. GLOBEC Focus 4 “Feedbacks from Changes in Marine Ecosystem Structure” General Objective: To co-operate with other ocean, atmospheric, terrestrial and social global change research programmes to estimate feedbacks from changes in marine ecosystem structure to the global earth system

  9. GLOBEC Focus 4, Activity 4.3 • Social Impacts of Changes in Marine Ecosystems • Working Group Goals: • To understand the interactions between marine coastal communities and global changes in marine ecosystems; • To understand the capacity of these communities to adjust to these changes; • To understand the consequences of these adjustments for marine ecosystems.

  10. Several issues complicate study of these interactions: • Scale • What are the scales at which marine ecosystems and coastal communities interact? • What are the scales of environmental change compared with scales on which humans have the ability to change and adapt. • How to move between scales when the drivers are global but the impacts local? • Knowledge • Open” and “Closed” knowledge systems – e.g. publicly available, local knowledge, or group-based. • How best to exchange and to incorporate scientific and local knowledge into decision-making? • Values • How to assign value to ecosystem states, e.g. is an system which supports Atlantic cod inherently better than one that supports northern shrimp?

  11. Example case study: Atlantic cod in Newfoundland Example case study: Atlantic cod in Newfoundland • The collapse of cod has been severe social disruption in Newfoundland. In addition to the social displacements, there have been changes in the ways that coastal communities use the marine ecosystems: • have expanded into previously un-fished species, • have expanded into new locations, • are using previous fishing grounds for species other than cod. • Result is potential for significant negative impacts on the marine ecosystem, and on the recovery of cod.

  12. Working Group Approach • Develop a review/appraisal paper on the topic “What are the impacts of marine ecosystem changes on coastal communities?”. • Case studies might include: Peru and changes induced by El Nino oscillations; NW Atlantic groundfish collapses • Explore “significant issues”, starting with “Scale” (a MS has been submitted) • Develop models coupling marine ecosystem changes with the socio-economic system. • Develop active links with other relevant programs, • e.g. GECaFS, by exploring these issues for the marine ecosystems of Peru, Chile and Ecuador; or possibly the Caribbean?
