A High Resolution Time-Series Particle Interceptor Trap

调查人员将设计、建造和测试一个新的上层水 可收集的柱状时序沉积物捕集器 重复沉降颗粒的样品，并使用 一种新型校准装置。 KATS（Knauer-Asper Time） 系列）存水弯将通过匹配现有和 可耐尔MULTITRAP和本庄转盘的成熟技术 目前安装在Mk VIc上的样品收集器 沉积物收集器 新的陷阱设计将提供采样 其他诱捕系统所不具备的能力， 比以前更高的采样分辨率和精度 达到。 使用现有的硬件将导致 减少备件和辅助设备， 计划使用这两种类型的陷阱的程序（例如，GOFS）。 KATS的校准将使用中性- 浮力沉积物收集器，不受水动力影响 偏差（全球海洋观测系统沉积物收集器研讨会报告，印刷中）。

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).
