Primera estimación de la tasa de fijación biológica de nitrógeno en Cuenca Alfonso, región sur del Golfo de California
Cristian Hakspiel-Segura y Aida Martinez Lopez
Nitrogen-fixation (FBN) rates were determined for the first time in the euphotic zone (0-43 m) and at 150 m depth using the high-sensitive 15N2 tracer method at Alfonso Basin, Gulf of California, during May 2012. In this study, high rates (437 ?mol N m-2d-1 depth integrated 0-150 m) were estimated under conditions of nutrientt enrichment and the expansion of hypoxic conditions relative to other observations restricted to the euphotic zone in systems of the Gulf and the Eastern North Pacific. These data support previous affirmations about the significant FBN regulation pathway on the nitrogen inventory in both, photic and aphotic zone
Palabras clave: Alfonso Basin; Nitrogen fixation; hypoxic conditions
