Book Description
Effects of siphonophores on sound propagation in the sea were studied by determining the size of gas bubbles they contain and produce, and the times, volumes, and rates involved in these processes. Major findings were: (1) gases contained in fresh siphonophore floats are generally close to ambient pressure, suggesting release of many bubbles during vertical ascent; (2) oxygen consumption may be elevated during production of CO; (:) diffusion constants for siphonophore floats are close to those for chitin; (4) calculated energy requirements for countering hydrostatic pressures indicate that float refilling times are probably no more than a few hours.
