Classification: CPC B  G | IPC B  G

Claim 0:
1. A method of conducting a marine seismic survey comprising:
autonomously landing a plurality of nodes on a seabed at respective first locations to form an array of nodes;
when the plurality of nodes are landed on the seabed at their respective first locations, transmitting seismic energy from a seismic source vessel;
using the plurality of nodes to acquire seismic data at the first locations;
varying buoyancy of the plurality of nodes between a positive buoyancy and a negative buoyancy to maintain the node within a transit envelope below a surface of the water and the seabed to facilitate transit of the nodes along an oscillating path from their respective first locations to respective second landed seabed locations without the nodes surfacing;
when the plurality of nodes are landed on the seabed at their respective second locations, transmitting seismic energy from the seismic source vessel; and
using the plurality of nodes to acquire seismic data at the second locations.
