    Abstract: Methods and systems are disclosed. The method include generating a simulated seismic training dataset, where the simulated seismic training dataset includes upgoing signals and downgoing signals, each recorded on hydrophones and geophones and training a deep learning network, using the simulated seismic training dataset, to separate the upgoing signals from the downgoing signals. The method also includes obtaining field hydrophone data and field geophone data pertaining to a subsurface region of interest, recorded by a seismic acquisition system including hydrophones and geophones, and separating the field hydrophone data and field geophone data into predicted upgoing signals. The method further includes generating a seismic image of the subsurface region of interest based, at least in part, on the predicted upgoing signals.

    Abstract: Ocean bottom seismic nodes formed of a non-metallic pressure housing that is substantially cuboid shaped, which may be formed of an injection molded plastic. The seismic node may have a detachable hydrophone housing that encloses a hydrophone and protects one or more external electrical connectors, which may have electrical connections that are substantially flat and flush with the hydrophone housing. A modular baseplate may be coupled to a bottom portion of the seismic node. A weight ballast may be positioned between the node housing and the modular baseplate. A mounting bracket may be coupled to an exterior portion of the seismic node without any direct fasteners.

    Abstract: An umbilical-based marine acquisition system includes an umbilical cable configured to be attached with a proximal end to a vessel and to provide compressed air to a seismic source, a sensor loaded section having plural seismic sensors distributed along a length of the sensor loaded section, the sensor loaded section being configured to be attached with a distal end to another sensor loaded section or to the seismic source, and an umbilical-sensor section connection configured to connect a distal end of the umbilical cable to a proximal end of the sensor loaded section. The umbilical-sensor section connection and the sensor loaded section are configured to transmit seismic data acquired by the plural seismic sensors to the vessel.
