## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The autonomous marine survey node of claim 1:
wherein the set spacing comprises a first set spacing in an x direction and a second set spacing in a y direction; and
wherein the x direction and the y direction are both orthogonal to a depth direction.

### Claim 11 (depends on 9)

The autonomous marine survey node of claim 9:
wherein the spike is configured to move relative to the autonomous marine survey node and the anchoring system is configured to drive the spike into the underwater surface by extending the spike from the node toward the underwater surface.

### Claim 12 (depends on 1)

The autonomous marine survey node of claim 1:
further comprising an autonomous auxiliary station configured to deploy or retrieve the autonomous marine survey node without human intervention.

### Claim 13 (depends on 12)
