Available in PDF, EPUB and Kindle. Book excerpt: Gas-filled siphonophore floats collected from a deep scattering layer (DSL) were photographed in the act of voluntarily expelling bubbles of nearly pure carbon monoxide. These observations suggest the possible release of free bubbles in the sea at depths considerably greater than previously known. Such free bubbles, together with the siphonophore floats themselves, constitute a biological family of potentially resonant sonar targets. Measurements of rates of gas production and diffusion, and of bubble and float dimensions, indicate the possibility of acoustic targets within the DSL which will resonate in response to sonar frequencies of less than 10 to greater than 110 kc/s depending upon depth.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
