A marine seismic data acquisition system and method of conducting a marine seismic survey are disclosed. The system incorporates one or more surface vessels, and a plurality of autonomous nodes for acquiring seismic data at one or more seabed locations. Each node comprises a USBL, SSBL or SBL transducer and USBL, SSBL or SBL acoustic modem. A first acoustic positioning system is operable between one of the surface vessels and the nodes, the first acoustic positioning system being a USBL, SSBL or SBL system. Each node of the plurality of autonomous nodes has a USBL, SSBL or SBL beacon address, with respective groups of nodes having the same beacon address. The nodes are configured such that no two nodes with the same beacon address can actively communicate over an associated USBL, SSBL or SBL modem at the same time.
