Follow this link to a collection of public datasets of
exploration-geophysical interest available for free download.
same datasets are also available from the SEG website,
their original home, but that way of downloading them is less preferred now.
Note, the datasets have legal disclaimers and requirements attached.
Before downloading datasets, first download their associated README
files and agree with the restrictions you find there.

with a separated header / data format very similar to classic SEPlib,
but rewritten from scratch. Madagascar includes an environment for
creating and testing reproducible software experiments.)
