Airships --- Basis for a New Oceanic Capability

Blimps, modernized versions of the U.S. Navy\´s antisubmarine and early warning airships of the 1940\´s and 50\´s, offer an untapped potential for ocean science and engineering. As buoyant aircraft, they are not only energy-conserving but could engage uniquely in protracted airborne operations for remote and in-situ sensing. Their range, endurance, and ability to use sound equipment could be useful in detecting, following, observing, and protecting marine life. By combining a "view from above" with an ability to "work from above", airships could add a valuable new dimension to scientific and engineering activities in the sea.
