Planktonic Foraminifera@Nannotax: A web resource for foraminifera taxonomy and biostratigraphy

点击翻译按钮获取中文摘要

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the last 30 million years (Oligocene to Present) and a previous Cretaceous to Eocene compilation from an older and now out-of-date database called Chronos.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.
