Planktonic Foraminifera Nannotax web resource

项目摘要

Planktonic foraminifera are minute, single-celled, marine microorganisms that float in the upper layers of the open ocean, producing chambered calcareous shells. They are an important part of the modern marine ecosystem and after death their shells sink to become one of the principal components of deep-sea deposits (microfossils). These fossils have a geological record stretching back almost 200 million years and they provide a simple and quick means of age-dating the rocks in which they are found. For this reason they are of great importance to a wide range of earth scientists, including industrial biostratigraphers. Using the small samples that come from subsurface boreholes, biostratigraphers are able to identify the oil and gas reservoir and source rocks of specific ages and can precisely steer while drilling to maximise hydrocarbon production. However, the effective use of foraminifera microfossils for age dating is dependent upon the availability of up-to-date and reliable information concerning their classification (taxonomy - which species is which, and why?), their ecology (which species live where, when and why?) and their geological history (which species lived when and where?). This type of taxonomic skill is in short supply and is difficult to acquire owing to the essential data being locked up in academic texts of limited availability - especially outside research institutions. Increasingly, end-users expect to be able to find such data via the internet but they are poorly served by current systems. In order to widen access to this crucial information we will develop a web resource called Planktonic Foraminfera@Nannotax or PF@N that we hope will become the online reference source for anyone needing to obtain basic to specialist information on planktonic foraminifera. The project will build on an online resource called Nannotax that we previously developed for another microfossil group, calcareous nannofossils, using NERC knowledge exchange funding. This resource has proved highly successful as shown by usage statistics and personal feedback. The foraminifera information will come from a combination of newly compiled data for the last 30 million years (Oligocene to Present) and a previous Cretaceous to Eocene compilation from an older and now out-of-date database called Chronos. The availability of this Chronos content will considerably aid the development of the database content. When completed, PF@N will provide a comprehensive listing of living and fossil planktonic foraminifera taxa ranging over 120 million years of evolutionary history. Each species will have a short description, age data, multiple illustrations, bibliographic references and original descriptions. There will be identification keys and linked pages providing information on study methods. Our Principal Investigators and Project Partners will ensure that expert information, much of it derived from NERC-funded UK research, will be incorporated into the resource and our industrial partners will 'test-drive' the system and provide feedback and applied expertise. We think that the development of this system is essential to the effective use of foraminifera in the hydrocarbon industry, but also to their application more broadly, for example, as used by palaeoceanographers, geochemists, palaeobiologists, plankton biologists and oceanographers. By removing the barriers to learning foraminifera taxonomy, identifying specimens and obtaining accurate information about species, we think that existing users will be able to expand their expertise and that this will also open the way to a range of new users.

浮游有孔虫是微小的单细胞海洋微生物，漂浮在开阔海洋的上层，产生有室的钙质壳。它们是现代海洋生态系统的重要组成部分，死后它们的贝壳下沉，成为深海沉积物（微化石）的主要组成部分之一。这些化石的地质记录可以追溯到近2亿年前，它们提供了一种简单而快速的方法来确定它们所在岩石的年龄。因此，它们对包括工业生物地层学家在内的广泛的地球科学家来说非常重要。利用来自地下钻孔的小样本，生物地层学家能够识别特定年龄的油气藏和源岩，并可以在钻井时精确转向，以最大限度地提高碳氢化合物产量。然而，有效地利用有孔虫微体化石进行年代测定取决于关于其分类的最新和可靠信息的可用性（分类学-哪个物种是哪个，为什么？），它们的生态（哪些物种生活在哪里，何时以及为什么？）以及它们的地质历史（哪些物种生活在何时何地？）。这类分类学技能短缺，而且难以获得，因为基本数据被锁在有限的学术文本中-特别是在研究机构之外。越来越多的最终用户希望能够通过互联网找到此类数据，但当前的系统却无法为他们提供良好的服务。为了扩大对这一关键信息的访问，我们将开发一个名为浮游有孔虫@Nannotax或PF@N的网络资源，我们希望它将成为任何需要获得浮游有孔虫基本到专业信息的人的在线参考来源。该项目将建立在一个名为Nannotax的在线资源基础上，该资源是我们之前使用NERC知识交换基金为另一个微体化石组（钙质超微化石）开发的。使用统计数据和个人反馈表明，该资源非常成功。有孔虫的信息将来自最近3000万年（渐新世到现在）的新汇编数据和以前的白垩纪到始新世汇编数据的组合，这些数据来自一个名为Chronos的旧数据库。Chronos内容的可用性将大大有助于数据库内容的开发。完成后，PF@N将提供一个全面的清单，列出超过1.2亿年进化历史的活的和化石的浮游有孔虫类群。每个物种将有一个简短的描述，年龄数据，多个插图，参考书目和原始描述。将有识别码和链接页面提供研究方法的信息。我们的首席研究员和项目合作伙伴将确保专家信息（其中大部分来自NERC资助的英国研究）将被纳入资源，我们的工业合作伙伴将“试驾”系统并提供反馈和应用专业知识。我们认为，这一系统的发展是必不可少的有效利用有孔虫在碳氢化合物工业，而且他们的应用更广泛，例如，使用的古海洋学家，地球化学家，古生物学家，浮游生物学家和海洋学家。通过消除学习有孔虫分类学、识别标本和获得有关物种的准确信息的障碍，我们认为现有用户将能够扩展他们的专业知识，这也将为一系列新用户开辟道路。
