Nutrient and phytoplankton dynamics in a coastal lagoon strongly affected by coastal upwelling

San Quintín Bay is a coastal lagoon influenced by the California Current System (CCS) coastal upwelling. Upwelling brings nutrient-rich waters near the bay mouth and tidal currents propagate those waters throughout the bay. Upwelling intensification and relaxation events occur with a period of ~2 we...

description San Quintín Bay is a coastal lagoon influenced by the California Current System (CCS) coastal upwelling. Upwelling brings nutrient-rich waters near the bay mouth and tidal currents propagate those waters throughout the bay. Upwelling intensification and relaxation events occur with a period of ~2 weeks, possibly due to the variability of circulation of the CCS. Off San Quintín, the CCS has an offshore component of the flux, causing upwelling intensification events as strong as off Point Conception (34.5°N), with high phytoplankton productivity. At the lagoon's mouth, upwelling is the main cause of variability for all physicochemical properties except temperature. Semi-diurnal tides are the main cause of variability for temperature. Nutrient remineralization at the sediments and turbulence induced by tidal currents and wind waves increase nutrient concentrations in the lagoon. At the heads of the bay, phytoplankton abundance was ten-fold lower, productivity and chlorophyll concentrations were three-fold lower, chlorophyll content per cell was three-fold higher, and turbidity was higher than at the mouth. The few available data suggest the hypothesis that the effect of ENSO events on phytoplankton biomass depends on the interdecadal regime shifts in the northeastern Pacific. At the lagoon's mouth and adjacent ocean, summer salinities as low as 32.4 suggest the arrival of water parcels that originate in the north, possibly the Columbia River estuarine plume.

Las surgencias acarrean aguas ricas en nutrientes cerca de la boca de la bahía y las corrientes de marea las propagan a través de toda la bahía. Existen eventos de intensificación y relajamiento de surgencias con un periodo de ~2 semanas, posiblemente debidos a la variabilidad de la circulación del SCC. El SCC tiene un componente de flujo hacia mar adentro frente a San Quintín. Esto causa eventos de intensificación de surgencia tan fuertes como los que se dan frente a Point Conception (34.5°N), con alta productividad fitoplanctónica. En la boca de la laguna las surgencias son la causa principal de variabilidad de todas las propiedades físicas y químicas, con excepción de la temperatura que es afectada principalmente por las mareas semidiurnas. La remineralización de los nutrientes en los sedimentos, y la turbulencia inducida por las corrientes de marea y el oleaje incrementan las concentraciones de nutrientes en la laguna. En los extremos internos de la bahía hay hasta diez veces menos abundancia de fitoplancton, tres veces menos productividad y concentración de clorofila, tres veces más alto contenido de clorofila por célula, y mayor turbidez que en la boca de la bahía. Los pocos datos disponibles sugieren la hipótesis de que el efecto de los eventos de El Niño en la biomasa del fitoplancton depende de los cambios interdecadales de régimen climático en el Pacífico nororiental. En la boca de la laguna y el océano adyacente, salinidades de verano tan bajas como 32.4 sugieren el arribo de parcelas de agua originadas en el norte, posiblemente de la lengüeta estuarina del Río Columbia.Iniversidad Autónoma de Baja California2015-01-062021-06-03T03:55:26Z2021-06-03T03:55:26Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed ArticleArtículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/251010.7773/cm.v30i1A.2510 https://hdl.handle.net/20.500.12930/7485Ciencias Marinas; Vol. 30 No. 1A (2004); 1-19Ciencias Marinas; Vol. 30 Núm. 1A (2004); 1-192395-90530185-3880reponame:Repositorio Institucional de la UABCSinstname:Universidad Autónoma de Baja California Surinstacron:UABCSenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2510/1498info:eu-repo/semantics/openAccessoai:repositorioinstitucional.uabc.mx:20.500.12930/74852024-09-18T21:37:54Z
