Long distance passive localization of vocalizing sei whales using an acoustic normal mode approach.

Passive Acoustic Detection and Localization of Vocalizing East Pacific Gray Whales (eschrichtius Robustus) by Means of Autonomous Sensors in Multiple Array Configurations Index of Proposal

Simultaneous localization of multiple broadband non-impulsive acoustic sources in an ocean waveguide using the array invariant.

The array invariant method, previously derived for instantaneous range and bearing estimation of a single broadband impulsive source in a horizontally stratified ocean waveguide, can be generalized to simultaneously localize multiple uncorrelated broadband noise sources that are not necessarily impulsive in the time domain by introducing temporal pulse compression and an image processing techni...

Underwater Broadband Source Localization Based on Modal Filtering and Features Extraction

Passive source localization is a crucial issue in underwater acoustics. In this paper, we focus on shallow water environment (0 to 400 m) and broadband Ultra-Low Frequency acoustic sources (1 to 100 Hz). In this configuration and at a long range, the acoustic propagation can be described by normal mode theory. The propagating signal breaks up into a series of depth-dependent modes. These modes ...

Acoustic and Visual Survey of Humpback Whale (Megaptera novaeangliae) Distribution in the Eastern and Southeastern Caribbean Sea

—Humpback whales (Megaptera novaeangliae) historically ranged throughout the eastern and southeastern Caribbean Sea during the winter months. Commercial whaling from the 1820s to the early 1900s depleted the population. A combined passive acoustic and visual survey for humpback whales was conducted to assess the current winter distribution of this species in areas where it was exploited to depl...

Acoustic Tracking of Humpback Whales: Measuring Interactions with the Acoustic Environment

Although there is some knowledge of the characteristics of sounds produced by baleen whales, little is known about the function of these sounds or how these whales interact with their acoustic environment in general. The Humpback whale Acoustic Research Collaboration, or HARC, is a large project that is undertaking a rigorous study of the effects of ambient noise (including conspecific vocalisa...
