The goal of this project is the development of a local area imaging network for polar regions that is remotely accessible via satellite high-speed data link. The primary purpose of this imaging network will be the performance of close-range three-dimensional photogrammetry for the remote determination of accurate spatial dimensions. By incorporating 3D-photogrammetry into the imaging system, the PIwill transform remote, close-range imaging from a simple observational tool to into a sophisticated quantitative tool for the accurate assessment of biological and physical systems in extreme environments.The rationale for this system is a critical knowledge deficit of vital life-historydata on polar pinnipeds and seabirds. In northern regions, significant marine life management decisions are being made in the absence of adequate data. In the Bering Sea ecosystem in particular, apex predators such as Steller sea lions have declined to about ten percent of peak population levels. Despite years of intense research, hypothesized competition between marine apex predators and fisheries industry remains untested, predominantly for lack of viable research approaches for obtaining crucial life history data. Such data include frequent accurate census and age structure information in rookeries, as well as body mass and condition estimates of individual animals prior to, during and after fishing seasons. In a novel approach, we propose to use remote 3D-photogrammetry to significantly increase temporal resolution and numerical accuracy of remote census operations, to determine the age structure of rookeries through measurements of animals lengths, and to use photogrammetric volume determinations as estimators of body mass, in a technique recently validated by our laboratories. The proposed Satellite-Linked Data collection and Photogrammetric imaging system (SLiDaP system) will consist of initially four independent sub-stations, linked via wireless LAN to a fifth core-station. All stations will contain ultra-high-resolution digital still cameras and PCs, and will be independently powered by solar panels and batteries. The core station will be remotely accessible via an INMARSAT high speed data link. Key system design criteria will center around extreme ruggedness, highest reliability with minimal service requirements, low temperature capability, complete independence from any local power and communications infrastructure, rapid system deployment capability, as well as very low environmental impact. Two prototype SLiDaP systems. The first system will be tested in Astoria, or for greater accessibility and early developmental refinement. The second prototype system will be tested under realistic field conditions on Ugamak Island, in the Aleutian Island chain.This cooperative proposal between Texas A&M University Laboratory for AppliedBiotelemetry & Biotechnolgy and the National Marine Mammal Laboratory (NMFS), brings together leading academic research and marine resource management laboratories, as well as the industry leaders in photogrammetry and mobile archival tag design. Our efforts aredesigned to enhance basic biological research as well as marine ecosystem management. The proposed system will have applications far beyond our projected use: geologists, glaciologist and vulcanologist should profit from the availability of accurate remote close-range measurements for monitoring of shore degradation, land movement hazards, or volcano hazards to arctic air traffic routes along the Aleutians.

该项目的目标是为极地地区开发一个局部区域成像网络，该网络可通过卫星高速数据链远程访问。该成像网络的主要目的是执行近距离三维摄影测量，以远程确定准确的空间尺寸。通过将3d摄影测量技术整合到成像系统中，pi将把远程、近距离成像从简单的观察工具转变为复杂的定量工具，用于在极端环境中准确评估生物和物理系统。该系统的基本原理是对极地鳍足类动物和海鸟的重要生活史数据的关键知识缺陷。在北部地区，重大的海洋生物管理决定是在缺乏足够数据的情况下作出的。特别是在白令海生态系统中，像虎头海狮这样的顶级捕食者已经减少到峰值数量的10%左右。尽管多年来进行了激烈的研究，但海洋顶级捕食者和渔业之间的假设竞争仍未得到验证，主要是因为缺乏获得关键生活史数据的可行研究方法。这些数据包括频繁的准确普查和栖息地的年龄结构信息，以及在捕鱼季节之前、期间和之后对个别动物的体重和状况的估计。在一种新颖的方法中，我们建议使用远程3d摄影测量来显著提高远程普查操作的时间分辨率和数值精度，通过测量动物的长度来确定栖息地的年龄结构，并使用摄影测量体积来估计体重，这是我们实验室最近验证的一种技术。拟议的卫星关联数据收集和摄影测量成像系统（SLiDaP系统）最初将由四个独立的分站组成，通过无线局域网与第五个核心站相连。所有空间站都将配备超高分辨率数码相机和个人电脑，并将由太阳能电池板和电池独立供电。核心站将通过国际海事卫星组织的高速数据链进行远程访问。关键的系统设计标准将围绕极端坚固性、最低服务要求的最高可靠性、低温能力、完全独立于任何当地电力和通信基础设施、快速系统部署能力以及非常低的环境影响。两个SLiDaP原型系统。第一个系统将在阿斯托里亚进行测试，或者为了更好的可访问性和早期的开发改进。第二个原型系统将在阿留申岛链的Ugamak岛的实际现场条件下进行测试。德克萨斯农工大学应用生物遥测和生物技术实验室与国家海洋哺乳动物实验室（NMFS）之间的这项合作提议，汇集了领先的学术研究和海洋资源管理实验室，以及摄影测量和移动档案标签设计方面的行业领导者。加强生物基础研究和海洋生态系统管理。拟议中的系统的应用将远远超出我们的预期用途：地质学家、冰川学家和火山学家将受益于精确的远程近距离测量，以监测海岸退化、陆地运动危害或沿阿留申群岛北极空中交通路线的火山危害。
