项目摘要

0000580DavisThis research project is conducted under the auspices of the National Oceanographic Partnership Program (NOPP). It addresses a major challenge in biological oceanography, which is the development of predictive capability. Pressing issues such as fishery yields, pollutant transfer, carbon cycling, and sound and light transmission in the ocean all require accurate predictions. The vast majority of marine species are planktonic during at least a portion of their lives and therefore have populations that grow and die while being transported by ocean currents. Episodic factors such as storms, water mass interactions, and predator-prey patchiness are a major source of variability in marine populations. At present, our predictive capability is limited by the sparseness of data and the inability to sample with adequate time and space resolution to capture episodic features that control population size.Recent technological advancements in automated plankton identification (via optical imaging) and in design of autonomous underwater vehicles (AUVs) make it plausible to sample plankton in association with other environmental variables (e.g. temperature, salinity, light, nutrients, fluorescence, currents) autonomously with high resolution in both time and space. Ultimately, networks of AUVs equipped with plankton imaging systems deployed in specific regions of the world ocean can be envisioned to provide quasi-synoptic high-resolution data in time and space.This project will merge plankton-imaging technology with AUV technology by incorporating the Video Plankton Recorder (VPR) into the REMUS AUV. The VPR is an underwater video microscope that images plankton and other particulate matter in the size range of 100 microns to 2 centimeters. The REMUS AUV is designed to carry a payload of scientific instrumentation on pre-programmed missions using a combination of long and ultra-short baseline navigation. With up to 6 hours of endurance using rechargeable lead acid batteries or 18 hours from primary lithium cells, REMUS is well suited for repetitivespace/time data sampling. The VPR design will be made modular such that generic use in other AUVs will be possible. This initial design will allow for on-board real time compression and storage of digitized video using wavelet compression hardware. The compressed video then will be uploaded for analysis with an automated image processing system. The new VPR-REMUS system will be tested in a variety of habitats using Eulerian and Lagrangian sampling methods to automatically quantify distribution patterns of plankton taxa, fluorescence, hydrography, and currents.
这个研究项目是在国家海洋学伙伴计划(NOPP)的支持下进行的。它解决了生物海洋学的一个主要挑战,即预测能力的发展。渔业产量、污染物转移、碳循环、海洋声光传输等紧迫问题都需要准确的预测。绝大多数海洋物种至少在其生命的一部分时间里是浮游生物,因此它们的种群在被洋流运送的过程中生长和死亡。风暴、水团相互作用和捕食者-被捕食者斑块等偶然性因素是海洋种群变异的主要来源。目前,我们的预测能力受到数据稀疏性的限制,无法以足够的时间和空间分辨率进行采样,以捕捉控制种群规模的偶然性特征。最近在浮游生物自动识别(通过光学成像)和自主水下航行器(auv)设计方面的技术进步,使得浮游生物与其他环境变量(如温度、盐度、光、营养物质、荧光、电流)的关联在时间和空间上具有高分辨率的自主采样成为可能。最终,配备浮游生物成像系统的auv网络可以部署在世界海洋的特定区域,以提供时间和空间上的准天气高分辨率数据。该项目通过将视频浮游生物记录仪(VPR)集成到REMUS AUV中,将浮游生物成像技术与AUV技术相结合。VPR是一种水下视频显微镜,可以拍摄浮游生物和其他颗粒物质,尺寸在100微米到2厘米之间。REMUS AUV设计用于在预编程任务中携带科学仪器的有效载荷,使用长基线和超短基线导航的组合。REMUS使用可充电铅酸电池续航时间可达6小时,使用原锂电池续航时间可达18小时,非常适合重复空间/时间数据采样。VPR的设计将是模块化的,因此可以在其他auv中通用。这个初始设计将允许使用小波压缩硬件对数字化视频进行实时压缩和存储。压缩后的视频将被上传到自动图像处理系统进行分析。新的VPR-REMUS系统将在各种栖息地进行测试,使用欧拉和拉格朗日采样方法,自动量化浮游生物分类群、荧光、水文和洋流的分布模式。
