Description:

A SYSTEM FOR CONTINOUS, ACCURATE, WIDE-SCALE OCEAN MONITORING FOR USE IN MARINE MAMMAL MONITORING, SEISMIC SURVEYING, AND NAVAL SONAR SURVEILLANCE

 

INV-16007

Inventors: Purnima Ratilal 

 

Background

 

Ocean monitoring and detection plays a critical role in many areas.  Observing marine mammal populations continuously in time and space across ocean areas is essential for the management of marine ecosystems and for accessing anthropogenic impacts.  Additionally, marine mammal monitoring is mandated by the Marine Mammal Protection Act in operations that involve transmissions of acoustic or seismic signals.  This including marine seismic and geographical surveys, as well as naval sonar surveillance.  The current approach, which uses a hydrophone or an array of hydrophones, has limitations in its range of detection, accuracy, and ability to differentiate marine mammal groups. 

 

Innovation

 

This technology uses passive acoustic waveguide sensing to instantaneously detect, localize and classify marine mammal vocalizations from diverse species, across large areas of ocean.  The system, which consists of both hardware and proprietary software, can also be used for seismic surveying in the oil and gas industry, as well as for use in naval sonar surveillance.  

 

Value Proposition

 

The key benefits of this technology include:

 

•       Provides continuous detection across large areas (10K sq. km), an increase of roughly 100x compared to hydrophones

•       Enhances signal-to-noise ratio (SNR) by a factor of 10x or more, compared to hydrophones, providing high-resolution directional sensing 

        capacity.

•       Ability to update geographic positioning and tracking in one minute intervals

•       Marine mammals from multiple species are simultaneously distinguished and classified by utilizing the unique time-frequency characteristics of their vocalizations

 

Commercial Applications

 

•       Marine mammal monitoring

•       Marine seismic and geographical surveys

•       Naval sonar surveillance

•       Oil/gas exploration
