Observing Internal Solitary Waves in the Lombok Strait by Coastal Acoustic Tomography [PDF]
Geophysical Research Letters, 2019 AbstractThe subsurface structures of internal solitary waves were observed over two days from 27 to 29 February 2019, by two bottom‐moored coastal acoustic tomography systems over a path length of 18.286 km in the Lombok Strait, Indonesia. One‐way travel times along the transmission path between the acoustic stations were determined for the first three
