Seismic acquisition: Geophysical principles
According to Textbook Revolution, a student-run site “dedicated to increasing the use of free educational materials by teachers and professors,” "This is a flash-based, online-only book that covers the acquisition of marine multichannel seismic data. Flash has a number of benefits: it works natively in all modern browsers, uses less bandwidth than other platforms, and allows for the fantastic full-color illustrations. This book is less well laid-out than others in the learningGEOSCIENCE collection, but is still useful for students of the discipline. The diagrams, in particular, are quite clear."
