Micropaleontology Reference Centre

Jordies Resolution

GNS Science is one of five sites around the world, and the only one in the Southern Hemisphere, holding a full microfossil reference set from selected sites drilled as part of the Integrated Ocean Drilling Program and predecessor organisations (Deep Sea Drilling Program - DSDP and Ocean Drilling Program - ODP). An additional seven sites (Satellite Reference Centres) hold partial collections.

The collection includes fossil preparations for four microfossil groups: calcareous nannofossils, foraminifera, radiolarians and diatoms.

Material comes from drilling legs 1 to 178, with each centre carrying identical sample sets.

In addition to the IODP standard microfossil reference material, the GNS Science facility holds extensive microfossil collections resulting from detailed biostratigraphic studies, by local micropaleontologists, of selected intervals in seafloor drillholes of the New Zealand region.

For a full description of the Integrated Ocean Drilling Program and current drilling operations visit the IODP web site.
