AB: In the northeastern Pacific Ocean we are developing a long-term oceanographic program (IMECOCAL) to understand the pelagic ecosystem response to the climate variability and climate change. The IMECOCAL program began in October 1997, and we are expecting to continue until at least 2008 year, with the CONACYT (Mexican Council of Science and Technology) and CICESE supports. The IMECOCAL program is quarterly visiting an oceanographic area of the southern California Current region off Baja California, with approximately 80 hydrographic stations. Also, we are planning two continuous sampling sites, one in northern, and another in the south of the Baja California Peninsula. One of our main goals is understand the interannual variability of the physical-biological interactions in the pelagic ecosystem, with the study of major oceanic physical processes, together with temporal changes of temperature and salinity in the water column, and their relationships with plankton fluctuations. Also, we are searching the long term signature of the climate change over the ocean, with sediments analysis collected at San Lazaro Basin, one of the few anoxic basins of the eastern Pacific Ocean. The program will be modeled the effects of climate variability on the structure of the pelagic ecosystem, selecting some planktonic key species. Also, using hydrographic and remote sensed information (SST, Color, and SSH), global models will be feed with local estimated phytoplankton photosynthetic parameters, to realize statistical analyses in order to define spatial and temporal variability of plankton biomass and primary production in this area.
