Siphonophores and the Deep Scattering Layer.

摘要: Bathyscaphe dives in the San Diego Trough have revealed a close spatial relation between siphonophores and deep scattering layer as recorded by precision depth recording echo-sounders. Measurements of gas bubbles within flotation structures Nanomia bijuga captured closing net an ascended indicate that these are very to resonant size for 12-kcy/sec sound. Because such organisms capable making prolonged vertical migrations, widespread geographically, they probably major cause stratified zones throughout oceans world.
