Phytoplankton assemblages and characterization of a Dinophysis acuminata population during an upwelling-downwelling cycle
Provedor de dados: 5
Autores: Gonzalez-gil, Sonsoles; Velo-suarez, Lourdes; Gentien, Patrick; Ramilo, Isabel; Reguera, Beatriz.
The distributions of Dinophysis acuminata, its potential prey Myrionecta rubra, and the microplankton populations associated with them, were studied in Ria de Pontevedra (NW Spain) during a 2 wk cruise that covered an upwelling-downwelling cycle, and during intensive sampling over 21 h at the end of the cruise. Special attention was focused on the characterization and physiological condition of D. acuminata. There was vertical segregation between a phytoplankton assemblage that was dominated by upwelling-promoted diatoms and another assemblage that was dominated by small dinoflagellates, located in the warmer surface layer (0 to 5 m) where D. acuminata was observed. High spatio-temporal variability was observed in the frequency of cells containing starch...

Tidal and wind-event variability and the distribution of two groups of Pseudo-nitzschia species in an upwelling-influenced ría
Provedor de dados: 5
Autores: Diaz, Patricio A.; Ruiz-villarreal, Manuel; Velo-suarez, Lourdes; Ramilo, Isabel; Gentien, Patrick; Lunven, Michel; Fernand, Liam; Raine, Robin; Reguera, Beatriz.
High-resolution physical and biological measurements were carried out in May-June 2007 during the ‘HABIT-Pontevedra 2007' survey in Ría de Pontevedra (Galician Rías Baixas, NW Spain) to study small-scale physical-biological interactions in the distribution of microphytoplankton, with special emphasis on harmful species. Longitudinal transects from the Ría to the adjacent shelf were sampled to describe the spring-neap tidal and circadian variability. An in situ particle profiler, a moored ADCP, and a towed undulating CTD (Scanfish) were used during the survey, which took place after an upwelling pulse at neap tides during a downwelling–upwelling cycle and coincided with the annual maximum of Pseudo-nitzschia spp. Cell maxima of P. seriata (2×106 cells L−1)...
