In this paper, we present marine mammal observation statistics, high-frequency seismic source characteristics, and example denoising of marine mammal acoustical recordings using data collected during the mitigation and monitoring program for a 3-D se

In many coastal environments, particularly in tropical zones, coral reef ecosystems have exceptional biodiversity, contribute to coastal defense, provide unique and important habitats and valuable commercial resources. Assessment of environmental imp

In this paper we propose a new biologically inspired model which simulates the visual pathways in the human brain used for classification of matching optical and sonar derived images. Marine mammals, such as dolphins, that live in waters with poor op

Humans are poor, if not incapable, at localizing sound underwater due to significant reduction in Inter-aural Temporal Differences (ITD) and Inter-aural Intensity Differences (IID) caused by reduced impedance mismatch and the higher sound speed in wa

The whistle repertoires of some dolphin species have been characterised and classified both qualitatively and quantitatively [1, 2, 3, 4, 5]; however, given the extensive range of the species relatively little is known about the acoustic repertoire o

Relaxor single crystals such as PZN-PT and PMN-PT exhibit superior electromechanical properties and are touted as the next-generation materials for future high performance piezo devices. This work describes a new hydrophone made of high-sensitivity P

Bottlenose dolphins (Tursiops truncatus) are the most widely studied species of dolphin and are known to produce a complex mixture of different types of sounds. They are believed to communicate through frequency-modulated pure tones (whistles), and p

The time reversal mirror (TRM) technique is a very useful tool in many underwater applications. Its usefulness in reverberation rejection and underwater communications has already been established through experiments by the Marine Physical Laboratory

We examine the use of Singular Spectrum Analysis (SSA) technique as an alternative technique to using standard wavelet shrinkage schemes for the purpose of de-noising mixtures of tonals, transients and Gaussian noise. Wavelet schemes require a calcul

A pacific bottlenose dolphin was trained in a two‐alternative cross‐modal matching‐to‐sample paradigm. The animal was able to inspect complex PVC‐pipe shapes through echolocation or vision but never through both senses simultaneously. Acous
