Normal mode separation and information extraction are popular topics in marine acoustics. The extraction of modal wavenumbers and modal depth functions using the data of a vertical line array is beneficial to various applications. In this paper. we systematically introduce a normal mode separation method based on the consistency restraint of the horizontal wavenumber. https://www.jmannino.com/best-price-Charge-Disposable-5000-Puffs-12mL-hot-choice/
