The Neptune database is a relational database of microfossil occurrence records from DSDP and ODP publications. It was produced by David Lazarus, Cinzia Spencer-Cervato, Hans Thierstein and colleagues at ETH-Zurich and has subsequently been implemented in various projects. It is currently being developed by David Lazarus, Haiko Paalike and colleagues who have made a version available to us. An extensive publication on the database is:
Spencer-Cervato, C., (1999). The Cenozoic Deep Sea Microfossil Record: Explorations of the DSDP/ODP Sample Set Using the Neptune Database. Palaeontologia Electronica, 2(2, art.4): 1-268.
Access to the nannoplankton data is possible from here - thanks to David Lazarus and Johann Renaudie. Following this link logs you in automatically without needing to create an account. The "about" link on the neptune site provides more information and contacts.
The database includes over 17,000 nannofossil samples and over 202,000 nannofossil occurrence records. For the other groups the totals are lower but of similar scale. So it is a very large data source, and there has been significant effort to enhance its' utility through production of uniform age models for each site and careful synonymising of taxa (for planktic forams this was done by Brian Huber, for nannofossils this was done initially by Katharina von Salis with updating subsequently by ourselves - Jeremy Young, Paul Bown, Jackie Lees). However.... the database does have major limitations
