项目摘要
This award, provided by the Antarctic Geology and Geophysics Program of the Office of Polar Programs, supports the development of a standardized diatom image catalog or database. Diatoms are considered by many to be the most important microfossil group used today in the study of Antarctic Cenozoic marine deposits south of the Polar Front, from the near shore to deep sea. These microfossils, with walls of silica called frustules, are produced by single-celled plants (algae of the Class Bacillariophyceae) in a great variety of forms. Consequently, they have great biostratigraphic importance in the Southern Ocean and elsewhere for determining the age of marine sediments. Also, paleoclimatic and paleoceanographic studies increasingly rely on fossil diatom data. Changing biogeographic distributions of given taxa indicate shifting paleoecological conditions and provide evidence of the surface productivity and temperatures of ancient oceans. The generality of conclusions, though, is limited by variation in species concepts among workers. The broad research community relies, directly or indirectly, on the accurate identification of diatom species. Current technology can be used to greatly improve upon the standard references that have been used in making these identifications.This project will develop an interactive digital-image catalog of modern and Cenozoic fossil diatoms of the Southern Ocean called "DiatomWare" for use by specialists and educators as an aid in rapid, accurate, and consistent species identification. As such, this will be a researcher's resource. It will be especially useful where it is not possible to maintain standard library resources such as onboard research vessels or at remote stations such as McMurdo Station. Major Antarctic geological drilling initiatives such as the new SHALDRIL project and the pending ANDRILL project will benefit from this product because they will rely heavily on diatom biostratigraphy to achieve their research objectives. The DiatomWare image database will be modeled on NannoWare, which was released in October 2002 on CD-ROM as a publication of the International Nannoplankton Association. BugCam will be adapted and modified as necessary to run the DiatomWare database, which can then be run from desktop or laptop computers. Images and text for the database will be scanned from the literature or captured in digital form from light or scanning electron microscopes.The software interface will include a number of data fields that can be accessed by the click of a mouse button. Primary information will be the images and descriptions of the holotypes. In addition, representative images of paratypes or hypotypes will be included whenever possible in plain transmitted, differential interference contrast light and, when available, as drawings and SEM images. Also included will be a 35-word or less English diagnosis ("mini-description"), the biostratigraphic range in terms of zones and linear time, bibliographic references, lists of species considered junior synonyms, and similar species. The list of similar species will be cross-referenced with their respective image files to enable quick access for direct visual comparison on the viewing screen. Multiple images can be brought to the viewing screen simultaneously, and a zoom feature will permit image examination at a wide range of magnifications. Buttons will allow range charts, a bibliography, and key public-domain publications from the literature to be called up from within the program. The DiatomWare/BugCam package will be distributed at a nominal cost through a major nonprofit society via CD-ROM and free to Internet users on the Worldwide Web. Quality control measures will include critical review of the finalized database by a network of qualified specialists. The completed database will include descriptions and images of between 350 and 400 species, including fossil as well as modern forms that have no fossil record.The development of the proposed diatom image database will be important to all research fields that depend on accurate biostratigraphic dating and paleoenvironmental interpretation of Antarctic marine sediments and plankton. The database will also serve as a valuable teaching tool for micropaleontology students and their professors, will provide a rapid means of keying down species for micropaleontologists of varying experience and background, and will promote a uniformity of taxonomic concepts since it will be developed and continuously updated with the advice of a community of nannofossil fossil experts. Broad use of the database is anticipated since it will be widely available through the Internet and on CD-ROM for use on personal computers that do not require large amounts of memory, costly specialized programs, or additional hardware.
该奖项由极地方案办公室南极地质学和地球物理学方案提供,支持开发标准化硅藻图像目录或数据库。硅藻被许多人认为是当今研究南极新生代海洋沉积物(从海岸到深海)最重要的微体化石类群。这些微化石,与壁的硅称为硅藻壳,是由单细胞植物(藻类纲硅藻)在各种各样的形式。因此,它们在南大洋和其他地方对确定海洋沉积物的年龄具有重要的生物地层学意义。此外,古气候和古海洋学研究越来越依赖化石硅藻数据。特定分类群地理分布的变化表明古生态条件的变化,并提供了古代海洋表面生产力和温度的证据。然而,结论的普遍性受到工人之间物种概念差异的限制。广泛的研究界直接或间接地依赖于硅藻物种的准确鉴定。目前的技术可以用来大大改进在进行这些鉴定时所使用的标准参考资料,本项目将开发一个名为“DiatomWare”的南大洋现代和新生代化石硅藻的交互式数字图像目录,供专家和教育工作者使用,以帮助快速、准确和一致地鉴定物种。因此,这将是一个研究人员的资源。在不可能维持标准图书馆资源的情况下,如在研究船上或在麦默多站等远程站,这将特别有用。主要的南极地质钻探倡议,如新的SHALDRIL项目和正在进行的ANDRILL项目将受益于这一产品,因为它们将严重依赖硅藻生物地层学来实现其研究目标。DiatomWare图像数据库将以NannoWare为模型,NannoWare于2002年10月作为国际微型浮游生物协会的出版物以光盘形式发行。BugCam将根据需要进行调整和修改,以运行DiatomWare数据库,然后可以从台式机或笔记本电脑运行。数据库的图像和文本将从文献中扫描或从光学或扫描电子显微镜以数字形式捕获,软件界面将包括一些数据字段,可以通过点击鼠标按钮访问。主要信息将是图像和描述的全息模型。此外,将尽可能以普通透射、差分干涉对比光以及图纸和SEM图像(如可用)的形式纳入标本或次标本的代表性图像。此外,还将包括一个35个字或更少的英语诊断(“迷你描述”),生物地层范围方面的区域和线性时间,参考书目,物种名单被认为是初级同义词,和类似的物种。相似物种的列表将与其各自的图像文件交叉引用,以便在查看屏幕上快速访问以进行直接视觉比较。多个图像可以同时显示在观察屏幕上,并且缩放功能将允许在宽范围的放大率下进行图像检查。这将允许范围图,书目,和关键的公共领域出版物的文献被称为从程序内。DiatomWare/BugCam软件包将通过一个主要的非营利协会以CD-ROM的形式以象征性的费用分发,并在万维网上免费提供给互联网用户。质量控制措施将包括由一个合格专家网络对最后确定的数据库进行严格审查。已完成的数据库将包括350至400个物种的说明和图像,其中包括化石以及没有化石记录的现代物种,拟议的硅藻图像数据库的开发对所有依赖于准确的生物地层年代测定和南极海洋沉积物和浮游生物古环境解释的研究领域都很重要。该数据库也将作为一个宝贵的教学工具,为微体古生物学的学生和他们的教授,将提供一个快速的方法键控下来的物种不同的经验和背景的微体古生物学家,并将促进统一的分类概念,因为它将开发和不断更新的建议,一个社区的nannofosalfus化石专家。预计该数据库将得到广泛使用,因为它将通过因特网和光盘广泛提供,供个人计算机使用,不需要大量的内存、昂贵的专门程序或额外的硬件。
