A High Resolution Time-Series Particle Interceptor Trap

调查人员将设计、建造和测试一种新的上层水柱时间序列沉积物捕集器，该捕集器能够收集沉降颗粒的重复样本，并使用新型校准设备对其进行校准。KATS(Knauer-Asper Time-Series)捕集器将结合Knauer MULTITRAP和Honjo旋转式样品采集器的现有和成熟技术来构建，该采样器目前安装在他的Mk Vic沉积物捕集器上。新的诱捕器设计将提供任何其他诱捕器系统所没有的采样能力，具有比以前更高的采样分辨率和精度。现有硬件的使用将减少计划使用这两种类型陷阱的项目的备件和支持设备池(例如，GOFS)。KATS的校准将使用中性浮力沉积物捕集器完成，该捕集器不受水动力偏差的影响(GOFS沉积物捕集器研讨会报告，正在出版中)。

The investigators will design, build and test a new upper water column time-series sediment trap capable of collecting replicate samples of settling particles and calibrate it using a novel calibration device. The KATS (Knauer-Asper Time- Series) trap will be constructed by mating the existing and proven technology of the Knauer MULTITRAP and Honjo rotary sample collector which is currently fitted to his Mk VIc sediment traps. The new trap design will provide sampling capability not available in any other trapping systems with higher sampling resolution and accuracy than previously attained. The use of existing hardware will result in a reduced pool of spare parts and supporting equipment for programs which plan to use both types of traps (eg. GOFS). Calibration of the KATS will be accomplished using a neutrally- buoyant sediment trap which will be immune to hydrodynamic biases (GOFS sediment trap workshop report, in press).
