a strong steel deep-sea diving sphere, lowered by cable



a strong, usually steel, sphere-shaped chamber with equipment for underwater observation; it is lowered on a cable from a surface vessel. There is equipment in the bathysphere for air regeneration, measurement devices, and a telephone; there are also several observation windows.

The first descent in a bathysphere was made by the Italian Balzamello in the Mediterranean in 1892, to a depth of 165 m. In 1911 the American engineer H. Hartman descended in a bathysphere in the Mediterranean to a depth of 458 m. In 1934 the Americans W. Beebe and O. Barton descended in the bathysphere Age of Progress to a depth of 923 m near Bermuda, and in 1948, after a series of improvements, O. Barton descended in a bathysphere near California to a depth of 1,360 m. Since the 1950’s hydrostats have been used instead of bathyspheres for oceanographic exploration (and in some cases, for work connected with the raising of sunken vessels).

Under Wheeler Mountain, I peered out my windows as if in a bathysphere, watching birds of passage or random mammals--a stalky bobcat, a sinuous fisher--and the wide, ancient, homely cliffs that towered up with cracks across them like the pentimento of a thin-lipped grin, and two slightly mounded, snoutlike nostrils near the top.
