多通道沉降物捕集器的设计主要用于对相对垂直颗粒流较大的湖泊、大陆架和水栖环境的沉积物的自动采集。在北极、南极、热带、亚热带等环境中，经过无数次的长期野外操作，已经证明了此沉降物捕集器的可靠性。这款沉降物捕集器不需要很重的固定线缆，沉降物捕集器在较小的船上也可以很容易地安置和收回。多通道沉降物捕集器的控制装置可以执行为期一年多的时间依赖性工作。为了防止沉降物捕集器捕集到的沉降物从收集筒的上部被冲走，沉降物捕集器的每个收集器在开口处都安装一个可拆卸的塑料网格，沉降物捕集器内部完全不含金属。当多通道沉降物捕集器的采集瓶不工作时，它们与周围环境是隔离的。在沉降物捕集器布放和回收操作期间，收集筒底部是开放的，允许水流自动流过收集筒腔体。5 e' e+ V& o6 j2 z Y. `- K: {
整个沉降物捕集器系统由3节长时间锂电池供电。根据不同的需求，不同多通道沉降物捕集器的收集瓶数量可以是6、12、24：豪华型多通道沉降物捕集器通过PC机上的一个HYDRO-BIOS软件进行预编程，允许用户实时（年、月、日、时、分）对沉降物捕集器的每个收集瓶的采样间隔单独预先设定，从1分钟至8760小时。豪华型采样器可通过增加各种参数的不同传感器进行升级，数据存储器容量可达4M。6 u$ i6 C% z/ D( R

德国HYDRO-BIOS公司MST24多通道沉降物捕集器参与了罗源湾沉积动力学科研项目。罗源湾位于福建省沿海东北部，闽江口以北约50公里，是少有的天然深水港湾，可全天候靠泊30万吨轮船。罗源湾具备建造东方大港的条件，从“十一五”期间开始，罗源湾成为福建省重点建设的港口。罗源湾在行政区划上隶属福州市，北岸属罗源县，南岸属连江县。根据海峡西岸经济区规划，列为福州港的深水外港。罗源湾在福建省、乃至中国港口的发展中有着非常重要的地位，对它的研究也势在必行。科研人员将MST24长期坐底式布放在罗源湾，成功捕集到了大量具有代表性的自然沉降物，为罗源湾沉积动力学的研究提供了真实可靠的数据。2 E' K$ q, W& L. _5 Y7 R, a8 K
