Transport of benthic diatoms across the continental shelf off southern Baja California Peninsula

Transport of benthic diatoms across the continental shelf off southern Baja California Peninsula

Material collected with a time-series sediment trap moored in San Lázaro Basin, near the NE Pacific upwelling zone off Bahía Magdalena, Baja California Sur (Mexico), from August to November 1996 and December 1997 to June 1998, revealed temporal changes in the flux of benthic diatoms. Fluxes were hig...

Fluxes were highest during fall and spring. Lateral transport of benthic diatoms from the coastal zone seems to be an important phenomenon at this site. The species assemblage includes components found mainly in mangrove environments of Bahía Magdalena, as well as nearby rocky coastlines, indicating that locally the northward counter current or coastal gyres carry living cells, and possibly other particles of lagoon origin, across the continental shelf. Material recolectado en una trampa de sedimento de serie de tiempo anclada en la Cuenca San Lázaro, cerca de la zona de surgencias del Pacífico nororiental frente a Bahía Magdalena, Baja California Sur (México), de agosto a noviembre de 1996 y de diciembre de 1997 a 1998, reveló cambios temporales en el flujo de diatomeas bentónicas. Los mayores flujos se registraron en otoño y primavera. El transporte lateral de diatomeas bentónicas desde la zona costera parece ser un fenómeno importante en la zona. Las asociaciones de especies encontradas incluye especies que se encuentran principalmente en ambientes de manglar de Bahía Magdalena, así como en los litorales rocosos cercanos, lo que indica que la contracorriente en dirección norte o los giros costeros acarrean localmente células vivas, y posiblemente otras partículas de origen lagunar, a través de la plataformacontinental.
