9318399 Widder The Harbor Branch Oceanographic Institution will develop and test a three dimensional, laser imaging and tracking electro-optical system (3-D LITES) for applications in biological oceanography. This laser-scanning system will provide precise 3-D data in near real time while combining high resolution (1.25 mm) with a large field of view (0.5 m) and a long working distance (1 m). The system will be for use both in the laboratory and in situ. 3-D LITES is a modification of a system developed for the the Navy for high resolution mapping of surfaces underwater. The image closely resembles a video image with 200 to 800 lines of resolution, but each frame is a 3-D data file where the "pixels" comprising the image have a "Z" component in addition to an X,Y coordinate, thus providing true three-dimensional imaging within the sensor's field of view. The work proposed is to adapt this design for mapping real time movements and microscale distribution patterns of marine organisms. The principal application is the measurement of spatial distributions and swimming patterns of motile organisms in the open ocean. This represents one of the greatest challenges in biological oceanography and holds the key to understanding zooplankton behavioral ecology by answering such basic ecological questions as how co-occurring species distribute themselves in space relative to each other and relative to the physical variables in their environment.

9318399 Widder海港分支海洋研究所将开发和测试一个三维激光成像和跟踪电光系统（3-D LITES），用于生物海洋学。这种激光扫描系统将在接近真实的时间内提供精确的三维数据，同时将高分辨率（1.25毫米）与大视场（0.5米）和长工作距离（1米）相结合。该系统将在实验室和现场使用。3-D LITES是为海军开发的水下表面高分辨率测绘系统的修改版。该图像非常类似于具有200至800线分辨率的视频图像，但每帧都是3D数据文件，其中构成图像的“像素”除了具有X，Y坐标之外还具有“Z”分量，从而在传感器的视场内提供真正的三维成像。拟议的工作是调整这一设计，以绘制海洋生物的真实的时间运动和微尺度分布模式。主要应用是测量公海中能动生物的空间分布和游动模式。这是生物海洋学中最大的挑战之一，也是理解浮游动物行为生态学的关键，因为它回答了一些基本的生态学问题，如共生物种如何在空间中相对于彼此和相对于环境中的物理变量分布。伊迪丝·威德港分支海洋研究所博士。Pierce，FL 34946
