Foraminíferos bentónicos recientes en sedimentos de fondo de la cuenca de panamá (pacífico colombiano), como indicadores de productividad y oxigenación
Thirteen deep-sea samples (core-tops) from the Panama Basin, Colombian Pacific, were analysed for benthonic foraminifera in the >150µm size fraction. Based on the microfaunal content, three zones are recognised in the Panama Basin: (1) northern euphrophic region (~8° to 5,5°N), characterized by a...
