Abstract: A seismic detection line includes one or more identified element(s) arranged in a string, and a telemetry link connecting the element(s) along the string to convey seismic data from at least one of the element(s) to a data recorder and identification data to a topology controller. Each of the element(s) includes a respective first identification unit connected to the telemetry link to provide a respective first identifier to the topology controller. A seismic detection system also includes a processor that queries the identified element(s) for their respective identifiers, determines an arrangement of the seismic detection line using the received identifiers, and presents an indication of the determined arrangement. A method of operating a seismic detection line includes transmitting a query along the telemetry link, detecting whether the respective identifier of one of the element(s) was received or not, repeating until termination, and determining and indicating the arrangement.

Abstract: An ocean bottom node for collecting seismic data, the ocean bottom node including a compounded housing including an electronics housing and a pinger housing, electronics located inside the electronics housing, and a battery pack configured to supply electrical power to the electronics. The pinger housing is permanently open to an ambient water while the electronics housing is sealed from the ambient water, and the pinger housing is configured to selectively and directly attach to the electronics housing.
