Abstract
Embodiments of the invention provide methods, systems, and apparatus for collecting seismic data in marine environments. An ocean bottom cable comprising a plurality of sensor nodes for collecting seismic data may be coupled to a submerged hub. The submerged hub may provide seismic data storage, power, clock, and other support for operating the sensor nodes. By providing a submerged hub, the ocean bottom cable may continue collecting seismic data in harsh environments such as the arctic, where the sea surface may be frozen.
