A hybrid buoy system capable of aerial operation, that in some embodiments includes a wireless communication technology to allow communication with other buoys and/or an external system. In some embodiments, a swarm of buoys may be capable of surface and/or air operation. These buoys may work together to perform collective tasks that individual buoys are not capable of. Buoy swarms may be programmed for cooperative and swarm behaviors for use in a broad spectrum of missions. At least some of the buoys may be configured for specialized sensing, increasing the collective sensing capabilities of the swarm. A mixed, swappable sensor suite may be used to accommodate an array of marine exploration applications, including both military and civilian applications.
