    Abstract: Embodiments of the invention provide methods, systems, and apparatus for collecting seismic data in a marine environment. An ocean bottom cable (OBC) comprising a plurality of sensor nodes for collecting seismic data may be deployed to and retrieved from an ocean bottom during seismic operations using a winch. Such deployment and retrieval operations may exert substantial stress on the OBC at an interface between the sensor nodes and cable segments of the OBC. A reinforcement sleeve is provided to reduce the mechanical stress at such interfaces.
