How to Use the Data Hypercube of DSDP Legacy Data

Return to the Data Hypercube


Bulk statistical and visual analysis of lithologic data is possible. Import the files into an analysis package such as Matlab, ArcMap, GMT, OceanDataView.

Questions can be addressed:

  • How have carbonate biogenic facies responded at global scales to past climate changes ?
  • What has the sedimentation rate been for the first 10 My on newly formed crust through the last 70 My ?
  • Where did carbonate facies change most either side of the severe Eocene-Oligocene paleoclimate/paleoceanographic change ?


Seismic sections need groundtruthing from lithological records, to support time-stratigraphic interpretations of the images. The lithological data can be applied directly to this task, especially as chronostratigraphic ages are associated. Psicat, gINT, and other software can be used to create lithologic columns that can be pictorially laid alongside seismic profiles. Scale corrections will be necessary to allow for velocities.

The data cube is comprehensible to people who are scientifically curious, but not equipped to handle the over-complex data formats that are generated by expeditions. It is an important role for scientists to make their data available and comprehensible to the public. With this data structure, browse spatially to find out what the earth's seabed is made of, even when buried deep. Students can make figures for projects. To help with this a Google Earth visual index to the data has been made.
