Geologic time is the intellectual theme that connects a wide variety of research endeavors in geoscience - missing is the corresponding cyberinfrastructure that allows the resources of all these endeavors to be pooled. CHRONOS's (Greek: time) purpose is to transform Earth history research by seamlessly integrating geoscience databases and tools.

Eocene Planktonic Foraminiferal Taxonomic Database Now Public
The Eocene Planktonic Foraminiferal Taxonomic Database provides customizable search capability in a relational database format for Eocene planktonic foraminifera. It primarily consists of images and text from the Atlas of Eocene Planktonic Foraminifera (P.N. Pearson, R.K. Olsson, B.T. Huber, C. Hemleben, W.A. Berggren, editors, 2006, Cushman Foundation Special Publication No. 41), which was prepared between 1997 and 2006 by members of the Eocene Planktonic Foraminiferal Working Group, who provided taxonomic and biostratigraphic information for 168 species that are considered as senior synonyms. SEM images of 114 primary type specimens are also included along with multiple views of numerous hypotypes for senior and junior synonym species. The database is searchable in single and multiple taxonomy, morphology, and time/space fields and the species records can be downloaded in a tab delimited format.

Using CHRONOS Timescale Converter Service Calls
The timescale converter web application accessible through the CHRONOS portal (Ref: http://portal.chronos.org/gridsphere/gridsphere?cid=tools_tsconvert) uses publicly available web service calls to the timescale service described by the WSDL document located at http://services.chronos.org:9090/axis/timescales.jws?wsdl. These services are available for use on any platform.
Simple clients to these end points can be created in any modern programming language.

Timescale Conversion
A web app is now available for converting from Berggren 95 to from GTS 2004 by means of aligning values to the paleomag reversals. There are other CHRONOS tools in the portal. These include timescale creator and timescale comparison.
