ABSTRACT The FAO's “blue transformation” roadmap necessitates a fundamental shift towards precision aquaculture to meet global food security targets while minimizing environmental footprints. This review provides a comprehensive overview of how artificial intelligence (AI) and decision support systems (DSS) serve as pivotal enablers for the “better ...

Whales and Sonar: Environmental Exemptions for the Navy's Mid-Frequency Active Sonar Training. [PDF]
Mid-frequency active (MFA) sonar emits pulses of sound from an underwater transmitter to help determine the size, distance, and speed of objects. The sound waves bounce off objects and reflect back to underwater acoustic receivers as an echo.

Probing waveforms and adaptive receivers for active sonar
Active sonar systems involve the transmission and reception of one or more probing sequences, which provide a basis for extraction of target information in a region of interest. The probing sequences at the transmitter and signal processing at the receiver play crucial roles in the overall system performance.

Active Military Sonar and Marine Mammals: Events and References [PDF]
The deployment of active sonar by the U.S. Navy and its potential impacts on marine mammals has been an ongoing issue of intense debate; regulatory, legislative, and judicial activity; and international concern. This report summarizes legal and political

High-Resolution Imaging Method of Deconvolution MIMO Sonar Based on Acoustic Homing Platform
To address the demand for precise imaging of the desired guidance part of a target by an undersea vehicle, this paper attempted to apply multiple-input multiple-output(MIMO) sonar imaging to the acoustic homing platform of an underwater vehicle for the ...

Abstract It has recently been demonstrated that modern recreational fish finders with high‐frequency (800 kHz) Sidescan transducers can detect submerged human bodies. This ubiquitous technology is widely used on the water and has the potential to be utilized for the rapid detection of submerged decedents in any waterbody.

Status and future of research on the behavioural responses of marine mammals to U.S. Navy sonar
A review of the status and future of research into behavioral responses of marine mammals to naval sonar exposure was undertaken to evaluate the return on investment of current US Navy funded programs, identify the data needs and the contributions of ...
