Abstract : SPAR (Seagoing Platform for Acoustic Research) is a stable oceanographic platform designed for precise study of the basic acoustic and oceanographic characteristics of the ocean. When operating at sea, the platform is placed in the vertical position with six-sevenths of its surface underwater. This report emphasizes the physical properties of the platform, its equipment, and the general methods used in the collection of data. (Author)
