Última Chlorophyll profiles and the water column structure in the Gulf of California ArchiMer Hidalgo-gonzalez, Raquel M; Alvarez-borrego, Saul. Remote sensors provide information on the photosynthetic pigment concentration for the upper 22% of the euphotic zone. To model primary production in the water column from satellite-derived photosynthetic pigments, estimates of the vertical distribution of pigment concentration are required. A Gaussian distribution function is used to represent the pigment vertical profile with four parameters. We used 268 chlorophyll concentration profiles from 1973 through 1993, to estimate these parameters. Cluster analysis of surface temperature was used to define the cool season as the period end of November-end of June, and the rest of the year is considered the warm season. Cluster analysis of surface temperature acid chlorophyll data grouped the stations into four...

Understanding and quantifying upwelling is of great importance for marine resource management. Direct measurement of this process is extremely difficult and observed time-series do not exist. However, proxies are commonly derived from different data; most commonly wind-derived. A local wind-derived coastal upwelling index (CUI) is reported for the period 1970-1996 and is considered representative for the eastern central Gulf of California, an important fishing area where no proxies exist. The index is well related to pigment concentration distribution, surface water temperature, and population dynamics of important fish resources over the seasonal time-scale. There is a biological response to ENSO activity not reflected by this index, indicating that...
