There is a wealth of new materials, including

- a new chapter about marine seismic exploration featuring both hardware presentation and the principles for acquisition and processing;

- a new chapter covering marine bioacoustics and the coexistence between marine life (especially marine mammals) and human acoustical activity;

- the addition of technological advances for measurement, especially in the field of bathymetry (interferomety);

- new sections about wave propagation, transducer technology, acoustical oceanography, data transmision
