Development of a Free-Fall Fluorescence Imaging and Acoustic Microstructure Profiler

该提案寻求资金来开发一个自由落体系统，用于观察海洋中的物理和浮游微生物。获取无污染数据的一个主要问题是船舶与海洋之间的相对运动，特别是船舶的起伏。尽管有几种不同的设计，将仪器连接到船上的水丝引起仪器包的运动。这种诱导运动可能会搅动我们试图测量的微观光学结构，并污染浮游动物游泳行为的测量。进行这些观察的理想平台是一个不受船舶运动污染的自由下落系统。这样一个系统将在仪器包之前获得未受干扰水域的物理和生物数据，从而在生物范围的尺度上获得浮游生物的结构和动态的三维视图。这种光学和声学成像结合产生的信息将是独一无二的，并从根本上改变我们看待海洋浮游生物的方式。

This proposal seeks funds to develop a free-fall system for the observation of physical and planktonic microstincture in the ocean. A major problem in acquiring uncontaminated data is the relative motion between the ship and the sea, in particular, ship heave. In spite of several different designs, the hydrowire linking the instrument to the ship causes motion of the instrument package. This induced motion may be stirring the microscale optical structures that we are trying to measure and contaminating measurements of zooplankton swimming behaviors. The ideal platform for making these observations is a fxee-falling system which would be uncontaminated by ship motion. Such a system will acquire physical and biological data in the undisturbed waters ahead of the instrument package giving a three-dimensional view of the structures and dynamics of plankton on the scale of the organisms ambits. The information generated by this combination of optical and acoustic imaging will be unique and fundamentally alter the way we view the oceanic plankton.
