Concentration of dissolved iron in the oxygen minimum zone off San Esteban sill, Gulf of California

Concentration of dissolved iron in the oxygen minimum zone off San Esteban sill, Gulf of California

Dissolved iron (Fed) concentrations are reported for the Gulf of California oxygen minimum zone (OMZ), which was located in front of San Esteban sill, between Subtropical Subsurface Water (SSW) and Pacific Intermediate Water. Mean Fed concentration in the OMZ was 3.84 ± 2.48 nM, with minimum and max...

Mean Fed concentration in the OMZ was 3.84 ± 2.48 nM, with minimum and maximum values of 1.48 and 10.02 nM. These concentrations are higher and are enriched in relation to the Tropical Northeast Pacific Ocean OMZ (0.25–1.2 nM), whose waters enter the gulf through SSW. Sediment resuspension and Fed-enriched waters cause the observed Fe increase at the stations located near San Esteban sill. On the other hand, the relatively lower Fed concentrations found at the stations farthest from the sill are the result of denitrification in the suboxic zone.  Se registran concentraciones de hierro disuelto (Fed) en la zona del mínimo de oxígeno (ZMO) del golfo de California, que se ubicó frente al relieve del umbral de San Esteban y entre el Agua Subsuperficial Subtropical (ASS) y el Agua Intermedia del Pacífico. La concentración promedio de Fed en la ZMO fue de 3.84 ± 2.48 nM, con un valor mínimo de 1.48 nM y un máximo de 10.02 nM. Estas concentraciones son mayores y están enriquecidas (8:1) en relación con las de la ZMO del océano Pacífico Nororiental Tropical (0.25–1.2 nM), cuyas aguas ingresan al golfo de California mediante el ASS. La resuspensión de sedimentos y aguas ricas en Fed provocan el incremento de este metal en las estaciones aledañas al umbral de San Esteban. Por otro lado, los valores relativamente menores son producto de la desnitrificación en la zona subóxica en las estaciones más alejadas del umbral de San Esteban 2013-06-01 2021-06-03T03:55:21Z 2021-06-03T03:55:21Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2199 10.7773/cm.v39i2.2199 https://hdl.handle.net/20.500.12930/7453 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2199/1440 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 39 No. 2 (2013); 231-237 Ciencias Marinas; Vol. 39 Núm. 2 (2013); 231-237 2395-9053 0185-3880
