Acoustics in water: synergies with marine biology
(2016)
Comunicació de congrés
Accés obertThis paper presents some of the bioacoustics related analysis that was performed on the ANTARES data, focussing on the year 2014. The data was processed for sperm whale, dolphin and shipping presence and grouped by hour ... -
Estudio de la contaminación acústica del litoral: Influencia en los cetaceos
(2005)
Text en actes de congrés
Accés obertDurante el curso 2001-2002 se realizó el primer proyecto conjunto de investigación de los estudiantes de secundaria de los IES de Vilanova i la Geltrú y la Escola Politècnica Superior d’Enginyeria de Vilanova i la Geltrú ... -
First record of humpback whale songs in Southern Chile: Analysis of seasonal and diel variation
(2018-02-08)
Article
Accés obertMale humpback whales (Megaptera novaeangliae) produce complex, patterned songs that are traditionally recorded on their breeding grounds. In this work, we report results from the first continuous acoustic monitoring of a ... -
Implementation of a method to visualize noise-induced hearing loss in mass stranded cetaceans
(Macmillan Publishers, 2017-02-06)
Article
Accés obertAssessment of the impact of noise over-exposure in stranded cetaceans is challenging, as the lesions that lead to hearing loss occur at the cellular level and inner ear cells are very sensitive to autolysis. Distinguishing ... -
Space–time and hybrid algorithms for the passive acoustic localisation of sperm whales and vessels
(2010-11)
Article
Accés restringit per política de l'editorialIn the frame of the European Sea-floor Observatory Network (ESONET) and in preparation of the Demonstration Mission Listening to the Deep-Ocean Environment (LIDO) algorithms for the automated real-time detection, ... -
Sperm whale long-range echolocation sounds revealed by ANTARES, a deep-sea neutrino telescope
(Macmillan Publishers, 2017-04-12)
Article
Accés obertDespite dedicated research has been carried out to adequately map the distribution of the sperm whale in the Mediterranean Sea, unlike other regions of the world, the species population status is still presently uncertain. ... -
Supervised time-delay estimation for the passive acoustic localization of cetaceans
(Universitat Politècnica de Catalunya, 2017-10)
Projecte Final de Màster Oficial
Accés obertTime-delay estimation is an essential part of a wide variety of signal processing applications. This paper follows up on earlier work for time-delay estimation using neural networks. Nonetheless, this work is specialized ... -
The autonomous acoustic buoy
(Universitat Politècnica de Catalunya, 2013-06)
Treball Final de Grau
Accés restringit per decisió de l'autorThe Acoustic Buoy is a project between the Laboratory of Applied Bioacoustics (LAB) and the Universitat Politècnica de Catalunya (UPC). In areas that the human activities produce high noise levels, such as oil exploration ... -
The nose of the sperm whale: overviews of functional design, structural homologies and evolution
(2016-06)
Article
Accés obertThe hypertrophic and much elongated epicranial (nasal) complex of sperm whales (Physeter macrocephalus) is a unique device to increase directionality and source levels of echolocation clicks in aquatic environments. The ...
