In attempt to study the spatial differences in autumnal equatorial upwelling intensity relative to bio-productivity in the eastern equatorial Atlantic, oceanographic in situ data along regions 10°W, 0°E, 2.5°E and 6°E, collected in the Gulf of Guinea during autumn cruise carried out in September 2007 were analyzed. The surface mean values for temperature along 10°W, 0°E, 2.5°E and 6°E are 25.02, 26.15, 26.88 and 25.60°C, respectively. There was eastward weakening of the equatorial undercurrent from 10°W until its complete disappearance at 6°E. The highest concentration of nitrate recorded at the surface at 10°W was attributed to the shoaling pycnocline observed at this region. The surface mean values for nitrate along 10°W, 0°E, 2.5°E and 6°E are 0.37,... |

Con el objeto de determinar el patrón de circulación en la Caleta AEOLIAN, en septiembre del 2006 se realizaron mediciones de corrientes a nivel superficial y subsuperficial, periodo correspondiente a una época seca (verano), durante este periodo se realizaron mediciones de perfiles de corrientes utilizando un correntómetro perfilador ADCP WHS300 y de manera adicional se realizaron mediciones de corrientes superficiales para lo cual se utilizaron flotadores a la deriva. El área de estudio esta sujeta a una intensa variación, probablemente debido a la acción conjugada de los vientos, al ciclo mareal, a los efectos topográficos por la cercanía a la línea costera, con velocidades promedios de 0.21 m/s en las capas superficiales, 0.18 m/s en las capas media y... |
