Data

The data releases listed here come from projects that used the Research Drilling Program to collect subsurface material and measurements. Drilling yields the cores, cuttings, borehole geophysical logs, and water samples that project scientists later process, describe, and publish. RDP's role is at the acquisition stage; the releases are issued by the science centers leading each study.
