本文介绍了一种新的放射虫玻片沉降方法，用于浮游生物、沉积物捕集器和深海沉积物样品的定量分析。将样品分布在水柱的表面上，并直接沉淀在载玻片盖玻片上。沉降装置是一根直径为44 mm的聚碳酸酯管，与90 x 95 x 28 mm的有机玻璃底座熔合。将沉降管底座用螺栓固定在承载盖玻片的铝基板上，并在分配样品之前用水填充。该方法允许87.3%的样品可用于显微镜分析，并允许对小至15 mg干容重的样品进行定量分析。
We present a new method for settling radiolaria onto slides for quantitative analysis of plankton, sediment trap and deep-sea sediment samples. Samples are distributed over the surface of a standing column of water and settle directly onto glass slide coverslips. The settling aparatus is a 44 mm diameter polycarbonate tube which is fused to a 90 x 95 x 28 mm plexi-glass base. The settling tube base is bolted to an aluminum baseplate bearing the coverslips and filled with water before the sample is dispensed. This method allows 87.3% of the specimens to be available for microscopic analysis and permits quantitative analysis of samples as small as 15 mg dry bulk weight of sample.
