The coastal region (<60 km) was found to be affected by coastal upwelling, causing phytoplanktonbiomass and production rates in this region to be up to two times higher than at the offshore stations. The highest surface Chla values were registered in May 2002 (>2 mg m-3), when the mean PP was 361 mgC m-2 d-1. The highest PP values were recorded in June 2003, with a mean value of 447 mgC m-2 d-1, and the lowest in November 2002, with a mean value of 200 mgC m-2 d-1. Satellite ocean color images, supported by our field data, suggest that the area off Cabo Corrientes can be characterized by three periods: (1) a relatively intense upwelling period, with high Chla and PP (spring); (2) an upwelling relaxation period, when the highest PP values of the year were recorded (late spring-early summer); and (3) a summer-fall period, with strong stratification and lowest Chla and PP values. The high PP registered for the region off Cabo Corrientes during the spring season leads us to conclude that this is an area of high fertility, similar to other rich regions in the Pacific Ocean off Mexico. 2009 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48013186004 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.2 Vol.35 |
