    • Abstract:
      Studies on suspended matter in inverse estuaries are relatively scarce compared with similar studies in classic estuaries. The longitudinal circulation pattern in such estuaries is opposite to that observed in classic estuaries and may significantly affect the transport of suspended sediments. The Upper Gulf of California is a macrotidal inverse estuary having negligible river input but sustaining a high concentration of suspended matter, mainly derived from erosion of bed sediments. The amount of suspended particulate matter in the water column is controlled by tidal resuspension. On the western side of the Upper Gulf, horizontal fluxes of suspended particulate matter integrated between 1 m and 5 m above the bed were influenced by near-bed density-driven flow during neap tides. Maximum neap tide fluxes during ebb tide were − 21.5 g·m−1·s−1 to −24.9 g·m−1·s−1 while peak fluxes during flood tide were one order of magnitude smaller. The loss of suspended sediment to deeper water was controlled by gravity currents, which are typical of the near-bed circulation of inverse estuaries. Similar outflow from the Upper Gulf was not observed on the eastern side.
    • Abstract:
      Los estudios sobre seston en estuarios inversos son relativamente escasos comparados con estudios similares en estuarios clásicos. La circulación longitudinal en los primeros es opuesta a la que se observa en los estuarios clásicos y puede afectar significativamente el transporte de sedimento en suspensión. El Alto Golfo de California es un estuario inverso, macromareal, con escaso aporte de agua dulce y con alta concentración de material en suspensión que proviene de la erosión de los sedimentos del fondo. La concentración de partículas suspendidas en la columna de agua está controlada por resuspensión debida a la marea. En la parte oeste del Alto Golfo, en mareas muertas, los flujos horizontales de partículas en suspensión integrados entre 1 m y 5 m del fondo fueron afectados por corrientes de gravedad. Durante el reflujo de la marea, los máximos flujos de material en suspensión fueron entre − 21.5 g·m−1·s−1 y −24.9 g·m−1·s−1; en cambio, durante el flujo, estos fueron un orden de magnitud menores. La pérdida de sedimento en suspensión hacia aguas profundas se debió a corrientes de gravedad, típicas de la circulación de fondo en los estuarios inversos. En el lado este del Alto Golfo no se observaron corrientes similares.
