Abstract
An example autonomous marine survey node can include a circuitry component including circuitry of a marine survey receiver, a ballast tank coupled to the circuitry component, and a maneuvering system coupled to the circuitry component. The ballast tank can be configured to adjust a buoyancy of the autonomous marine survey node. The maneuvering system can be configured to autonomously perform aerial maneuvers and autonomously perform submersed maneuvers near an underwater surface.
Claims14
An autonomous marine survey node, comprising:
- a circuitry component including circuitry of a marine survey receiver;
- a ballast tank coupled to the circuitry component and configured to adjust a buoyancy of the autonomous marine survey node;
- a maneuvering system coupled to the circuitry component and configured to:
- autonomously perform aerial maneuvers when the autonomous marine survey node is airborne;
- and
- autonomously perform submersed maneuvers when the autonomous marine survey node is submerged in a body of water;
- and
- a location control system configured to:
- determine a position of the autonomous marine survey node relative to another autonomous marine survey node via acoustic communication when the autonomous marine survey node is submerged in the body of water and before it comes to rest on an underwater surface;
- and
- maneuver the autonomous marine survey node relative to the other autonomous marine survey node to establish a set spacing from the other node as the nodes descend in the body of water toward the underwater surface, such that the nodes form a marine survey node array exhibiting the set spacing when they come to rest on the underwater surface.
