Opdyke EAR-0003374 New Title: "Update of Paleomagnetic Databases for the years 2001-2002". This award will fund continued maintainance and updating of numerous paleomagnetic databases. The update of the paleomagnetic databases is in a transitional phase during this two-year period. Dr Michael McElhinny is retiring and has handed over this task to Dr Sergei Pisarevsky at the Tectonics Special Research Centre, University of Western Australia, Perth, Western Australia. Although Dr Pisarevsky is well-versed in databases, including their design and operation, Dr McElhinny has agreed to act in a supervisory capacity during this transitional phase. At the present time the databases are set up under either MS Access 97 or MS Access 2000. This will be continued for the present, but the possibility that a more modern database system could be used is being investigated under the new Geoinformatics and other database initiatives being developed in the Geosciences. Until now the databases have been updated annually, but this will now be undertaken every six months. Updates will appear immediately on the web through the web-site at the Geological Survey of Norway as has been available for updates over the past three years. Indeed as far as the Global Paleomagnetic Database (GPMDB) is concerned this web-site is the way in which most users currently access the database. The following databases will be automatically updated: GPMDB - Global Paleomagnetic Database for directions and pole positions MAGST- World-wide Database for magnetostratigraphy. PSVRL - Paleosecular Variation from Lavas for the past 5 Myr. The following databases rely heavily on researchers sending in their data, since the details are often not given in publications. SECVR - Secular Variation from Lake sediments and Holocene deposits. These data are never published in detail (only plots of Declination and Inclination versus Time are given. At present this database has as much data as can currently be obtained. Many researchers have not responded to requests for their data. TRANS - Reversals transitions database. Reversal transitions from lava sequences are published in the literature in full, lava flow by lava flow. However, transitions observed in sedimentary sequences are not given in detail horizon by horizon and again must be obtained from authors. This database is up to date as far as has been possible to get these sedimentary records in detail. The following databases are compiled and updated by others: PINT - Global Paleointensity Database. This is compiled and updated by Dr Mireille Perrin at the University of Montpellier, France. ARCHEO - Archeomagnetic Database. This is compiled and updated by Dr Don Tarling at the University of Southampton, UK.

Opdyke CN-0003374新标题："2001 - 2002年古地磁数据库更新"。 该奖项将资助许多古地磁数据库的持续研究和更新。 在这两年期间，古地磁数据库的更新处于过渡阶段。Michael McElhinny博士即将退休，并已将这项任务移交给西澳大利亚珀斯西澳大利亚大学构造学特别研究中心的Sergei Pisarevsky博士。虽然Pisarevsky博士精通数据库，包括数据库的设计和操作，但McElhinny博士已同意在这一过渡阶段担任监督职务。目前，数据库是在MS Access 97或MS Access 2000下建立的。目前将继续这样做，但在新的地球信息学和地球科学领域正在开发的其他数据库举措下，正在研究使用更现代化的数据库系统的可能性。到目前为止，数据库每年更新一次，但现在将每六个月更新一次。最新情况将通过挪威地质调查局的网站立即在网上公布，过去三年来一直提供最新情况。事实上，就全球古地磁数据库（GPMDB）而言，该网站是大多数用户目前访问该数据库的方式。以下数据库将自动更新：GPMDB-全球古地磁方向和极位数据库MAGST-全球磁性地层学数据库。PSVRL-过去500万年熔岩的古长期变化。 以下数据库在很大程度上依赖于研究人员发送的数据，因为出版物中通常没有给出详细信息。SECVR-湖泊沉积物和全新世沉积物的长期变化。这些数据从未详细公布过（只给出了下降和倾斜与时间的关系图。目前，该数据库拥有目前能够获得的所有数据。许多研究人员没有回应提供数据的请求。TRANS-反转转换数据库。从熔岩序列的反射转换发表在文献中的全部，熔岩流熔岩流。然而，在沉积层序中观察到的过渡并不是逐层详细给出的，而且必须再次从作者那里获得。这个数据库是最新的，尽可能得到这些沉积记录的细节。 以下数据库由其他人编制和更新：PINT-全球古强度数据库。这是由法国蒙彼利埃大学的Mireille Perrin博士编辑和更新的。ARCHEO-Archeomagnetic Database.这是由英国南安普顿大学的唐·塔林博士汇编和更新的。
