Phytoplankton samples were taken at mesophothic depths (30–150 m) over the Frijol Bank seamount inside the Corales de Profundidad National Natural Park during the dry and rainy seasons. Sixty-four forms (genera and morpho-species) of phytoplankton were found. Seasonal influence on phytoplankton assemblage structure was detected, with a number of genera preferentially associating with the dry season. Although not statistically significant, mean cell density was higher in the rainy than in the dry season whereas mean richness was the same for practical effects. Contrasting seasonal signals on phytoplankton assemblages in other Colombian Caribbean localities in comparison with the present work are discussed.

哥伦比亚加勒比海Proaleidad国家自然公园的中性浮游植物的组装结构和季节性

在干燥和雨季，浮游植物样品是在Corales de Profundidad国家自然公园内弗里霍尔河岸海面的中生深度（30–150 m）处采集的。发现了64种浮游植物形式（属和形态物种）。发现了对浮游植物组装结构的季节性影响，其中许多属优先与干旱季节相关。尽管没有统计学显着性，但雨季的平均细胞密度要比旱季的要高，而平均富集度对于实际效果是相同的。与目前的工作相比，讨论了哥伦比亚其他加勒比海地区浮游植物组合的季节性信号对比。
