Coastal, Ocean, and Land Linkages in North American Carbon Cycle

1. Coastal, Ocean, and Land Linkages in North American Carbon Cycle Dr. Arturo Muhlia Melo amuhlia04@cibnor.mx JNACP-2007

2. Outline • General frame work • General consensus • Sources of variability • Impacts in biological processes • Basic research in Mexico • Collaborative projects • Suggested questions of carbon cycle

4. Long term variation of temperature

6. There is consensus in science that gas emissions are increased by anthropogenic activities(CO2, CH4 y CO) • The Academy of science of the United states concluded: • The most vulnerable part of models to predict Global Change are the uncertainties related to the magnitude and temporal variability and geographic patterns of carbon sources and reservoirs in coastal regions of the world.

10. Biological processes

11. Sources of variability • Coastal environments interact directly to terrestrial air masses. • Due to the sensibility of wind patterns and river water flow and anthropogenic impacts due to the loads of nutrients and carbon, coastal regions are highly vulnerable to Global Change variability.

12. Sources of variability • Large scale phenomena El Niño and La Niña are more intense and more frequent. This impact to regional and local coastal zones ecosystems. • Tele connections and local processes have been observed in specific regions. In particular in the Pacific and Atlantic coast of North America. • Regional events Hurricanes and local processes like Red tides are more often observed in coastal areas.

13. The ENSO impacts in different ways the Pacific coasts of America.

14. Hurricane Wilma

15. Local eventsRed Tides Pacific coast of Central and North America have been affected more often with harmful Algae

16. Tele connections Tuna fishery: El Niño event increases recruitment of Yellowfin tuna fishery in the west coast of Mexico • Fish. Bull. 104:197–203 (2006). • Variation in yellowfin tuna (Thunnus albacares) catches related to El Niño-Southern Oscillation events at the entrance to the Gulf of California. A northward displacement of YFT seems to occur at the entrance of the Gulf of California twelve to fourteen months after El Niño events.

17. Basic research • In Mexico • Short term data collection for Carbon Cycle in coastal and ocean areas. Basically primary productivity in coastal zones, fewer in deep ocean waters, less studies in pelagic zone and fewer in the benthic zone. • Oceanographic studies : UMBRALES; IMECOCAL; PROCOMEX; PEGoT • FLUCAR (IMECOCAL, CO2 in Mexican coasts of the Pacifc) • Coastal zone studies: Local research

20. Objectives of this project • To estimate using historical satellite data and in situ observations of carbon fluxes variability of the Mexican seas. • To establish a net work monitoring stations along the west coast of Mexico. This will generate time series of environmental variables. • To generate data basis to improve prediction models. • The roll of Green Gases in coastal waters of México. • National Inventories of Green Gases. • Back ground information relevant to Global Chance convention and Kyoto protocol.

21. Coastal zone of the three countries • There is a new initiative organized in November 2006 in Seattle, Wa. NOAA (Cris Sabine, Dick Feely), Universities of Canada and Mexico • Sampling will start this year. (every two yrs) from Vancouver, Can to Punta Eugenia BC Mexico. The common fact is the California Current

22. La Paz, Baja California CIBNOR-SDSU example of collaboration • Carbon flux tower (PMC Mega project) • Airplane research • Marine station as part of the FLUCAR project

29. Suggested questions for the three countries • ¿What are the estimates of sources and sinks at the aquatic ecosystems in North America? • ¿What is the temporal and spatial variation of carbon fluxes in this region? • ¿What are the estimates of the impact of anthropogenic activities related to sources and sinks of C in ocean, coastal and land ecosystems? • Identify C flux interactions between aquatic and terrestrial and aquatic and atmosphere areas.
