SAN DIEGO, CA - DeepSea Power & Lights SeaSpheres™ are engineered to be the highest performance buoyancy product available today for missions to depths greater than 4000m. The spheres unique combination of light weight and high strength allow for larger ROV payloads and longer AUV survey missions in the worlds deepest diving vehicles and scientific instrument platforms. Now, with the release of the largest SeaSphere™ to date, a 216mm (8.5 inch) diameter seamless, hollow ceramic sphere, DeepSea offers an alternative to syntactic foam and glass spheres for users who demand a high buoyancy, minimal weight float rated for full ocean depth.

SeaSpheres™ are currently being manufactured as the primary flotation for a new ROV/AUV that will be used to explore the deepest areas of the Challenger Deep (10,912m). The spheres were chosen for this application based on their low "over the side" weight and their ability to withstand the rigors of long deployments at extreme depths. Another advantage of SeaSpheres™ is that they can be manufactured with varying wall thickness' in order to tailor their weight and strength to mission requirements. The spheres are also suitable for variable buoyancy systems.

SeaSpheres™ are cast from high purity alumina (Al2O3), an incredibly strong and lightweight ceramic. In fact, the material is so strong that the spheres buoyancy increases with depth. Alumina is an excellent electrical insulator, transparent to radio frequencies and virtually inert in caustic environments. SeaSpheres™ are engineered with a seamless design and held to exacting tolerances during manufacturing and testing to insure a long and reliable service life. Plans for even larger spheres are in development.

The ceramic spheres continue DeepSea Power & Light's commitment to designing best-value products for users who demand uncompromising quality, reliability and service. For more information on how DeepSea's products can simplify and improve your applications, please contact DeepSea Power & Light.
