The CHRONOS System is a growing network of hosted and federated relational databases and data files containing mainly published sedimentary rock data pertaining to Earth history and collected from globally distributed marine cores and terrestrial outcrops. These data sets are fully attributed and include paleobiological, geochemical, geochronological, lithologic, and magnetostratigraphic data with related temporal and spatial information.

Some information about the various data sources available here and in the Searches tab

NEPTUNE is a relational database of microfossil occurrences reported in Deep Sea Drilling Project and Ocean Drilling Program samples. NEPTUNE contains the occurrences of about 8'800 plankton species names (nannofossils, foraminifera, diatoms, and radiolarians) in Mesozoic and Cenozoic samples of approximately 230 DSDP and ODP drill holes from all ocean basins.

The NEPTUNE database was developed at the ETH Zürich and is currently hosted by CHRONOS ( It contains quality-controlled, micropaleontology and stratigraphy data from DSDP-ODP for taxonomic and evolution studies. Tools include graphic correlation. The database schema is in Postgresql. Further information on the history and conception of Neptune can be found in Spencer-Cervato (1999, Palaeontologia Electronica )

PaleoStrat is a collaborative digital information system for sedimentary, paleontologic, and stratigraphic data designed to help phylogenetic, paleobiologic, sequence stratigraphic, chemostratigraphic, deep-time paleoclimatology, basin analysis, paleogeographic, and other studies that address a variety of questions about the evolution of the Earth's tectonostratigraphic systems. (

Paleobiology Database's purpose is to provide global, collection-based occurrence and taxonomic data for marine and terrestrial animals and plants of any geological age, as well as web-based software for statistical analysis of the data. ( Hosted at the National Center for Ecological Analysis and Synthesis [NCEAS], Univ. California at Santa Barbara), Paleobiology is federated to the CHRONOS System.

The Time scale database consists of the data and information included in the 2004 Global Time Scale of the International Commission on Stratigraphy ( with an XML interface, 19 older time scales (from Holmes 1937 to Remane et al., 2000), and tools that allow to convert ages between some of the time scales.

The Mesozoic Planktic Foraminifera Taxonomic database is a hosted expert-defined relational taxonomic database with over 300 senior synonym species records that include original and emended species descriptions, morphologic descriptor fields, biostratigraphic range information, images of the species holotypes, and SEM images that illustrate the morphologic variability of the species concept.

The Atlas of Paleocene planktic foraminifera contains description and illustrations of 67 species description with SEM images and paleobiogeographic maps (). An interactive guide to Cretaceous planktic foraminifer taxa () is also hosted by CHRONOS.

Janus is the Ocean Drilling Program's Oracle relational database. The database contains 450 tables of ODP's marine geoscience data that are collected onboard the drillship JOIDES Resolution. The database includes paleontological, lithostratigraphic, chemical, physical, sedimentological, and geophysical data for ocean sediments and hard rocks. Janus has been used to collect data since Leg 171A (January 1997). During the first postcruise (moratorium) year, access to proprietary ODP data is only given to scientists who participated on the cruise. Proprietary data are released to the public one year after the end of each cruise. Non-proprietary data such as ODP & DSDP site information are available to everyone. Data collected prior to Leg 171A are being added to Janus as time permits. JanusLegacy, a clone of Janus with publicly released data, is networked with CHRONOS System.

Information Integrator

The information integrator system allows us to conduct searches that span across multiple databases on various systems at various locations. At present the CONOP9 searcg in the Conduction Searches section using this to search across Neptune, Janus and Paleostrat for data. If you have seaches you are interested in that might span across the various databases federated by this system please get in touch with us and let us know.
