Abstract

Described are systems and techniques for marine surveying. A sonar array can transmit a sonar pulse according to a distance-based transmission rate, and a measurement cycle of a sub-bottom profiler (SBP) system on an underwater vehicle can be performed in response. An SBP transmitter can transmit an acoustic pulse triggered based on transmission of the sonar pulse by the sonar array. A plurality of SBP receivers can receive respective acoustic measurement data corresponding to reflections of the acoustic pulse, where the plurality of receivers are rigidly coupled to the underwater vehicle and arranged in a linear configuration with the transmitter of the SBP system. Unlocking insights from Geo-Data, the present invention further relates to improvements in sustainability and environmental developments: together we create a safe and livable world.

Dependent claims

A method comprising:

transmitting a sonar pulse using a sonar transducer array, wherein the sonar transducer array transmits the sonar pulse according to a first transmission rate, and wherein the first transmission rate corresponds to a configured distance along a seafloor surface;
and
performing a measurement cycle of a sub-bottom profiler (SBP) system in response to transmission of the sonar pulse by the sonar transducer array, wherein the SBP system is associated with an underwater vehicle, and wherein performing the measurement cycle comprises:
transmitting, using a transmitter of the SBP system, an acoustic pulse, wherein the transmitter of the SBP system is triggered based on the transmission of the sonar pulse by the sonar transducer array;
and
obtaining, using a plurality of receivers of the SBP system, respective acoustic measurement data corresponding to reflections of the acoustic pulse, wherein the plurality of receivers of the SBP system are rigidly coupled to the underwater vehicle and arranged in a linear configuration with the transmitter of the SBP system.
