HYDRO-BIOS: Multi Sediment Trap

Category: Multi Sediment Trap
Art.No.: 444 1xx
Keywords: Multi Sediment Trap, MST
Supplier: Qingdao Watertools Technology?Co., Ltd.

Introduction:

The rugged titanium array of the Multi Sediment Trap encapsulates the singular standard Sediment Trap (444 000) together with a motor-driven rotary table that can accommodate 6, 12 or 24 plastic collecting bottles. The instrument has been designed as a light and handy instrument for autonomous operations in lakes, continental sheIf and aquatic environments with relative high vertical particulate flux value. It has proven its reliability during numerous long-time operations in arctic, antarctic, tropic and sub-tropic environments. The instrument does not need heavy moorings and can be easily deployed and recovered from smaller vessels. The cylindrical trap is equipped with a dismountable baffle grid at the opening to reduce turbulences, avoiding wash out of the sediment from the upper part of the cylinder. The inside of the trap is completely metal-free. The tubular design of our Sediment Trap provides a relatively small sampling area but cares for reliable sedimentation of suspended matters even under turbulent environmental conditions. It avoids the risk of re-suspension of the sample as it can regularly be detected inside large-area conical sediment traps. The collecting bottles of the Multi Sediment Trap are isolated from the surrounding environment when inactive. During deployment and recovery operations the trap bottom is open allowing a free flow through the body. Power supply is made by 3 long-time lithium batteries, placed inside an external battery housing. The operation schedule is programmed via PC by using OceanLab 3 software. Preselect active periods for the collecting bottles from 1 minute up to 8760 hours in real time (year, month, day, hour, minute) or as individual time intervals (hours and minutes).

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，已经证明了它的可靠性。这╳款仪器不需要很重的固定线缆，它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。为了防止捕集到的沉降物从收集筒的上部被冲走，每个收集器在↘开口处都安装一个可拆卸∑的塑料网格，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。

整个系统由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）对每ξ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ζ　不同传感器进行升级，数据存储器容量可达4M。

MST24坐底式布放

德国HYDRO-BIOS公司MST24多通道沉降物捕集器参与了国家海洋局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，是全∏国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ㄨ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，成功捕集到了大量极具代表性的自然沉降物，为罗源湾沉积动力学的研究〇提供了真实可靠的数据。
