Benthic foraminifera of surface samples and sediment cores off Senegal and Gambia, West Africa

Water depth zonation of fifty nine benthonic foraminiferal species in marine sediment surfaces has been described. Some species are combined to groups which mark particular depth zones: an upper and lower shelf-fauna, an upper and lower slope fauna, and a shelf-slope fauna. Dependence on latitude could be ascertained for Textularia panamensis, and submergence effects for Hyalinea balthica.本研究已系统记述海洋表层沉积物中59种底栖有孔虫（benthonic foraminiferal）的水深分带特征。部分物种被划分为可指示特定水深带的类群：涵盖陆架上、下带动物群，陆坡上、下带动物群，以及陆架-陆坡过渡动物群。 可明确巴拿马管编织虫（Textularia panamensis）的纬度依存性，以及巴尔透明虫（Hyalinea balthica）的淹没效应。
