Commercial cuttlefish exposed to noise from offshore windmill construction show short-range acoustic trauma
(2022-11)
Article
Accés obertThe installation of marine renewable energy devices (MREDs, wind turbines and converters of wave, tidal and ocean thermal energy) has increased quickly in the last decade. There is a lack of knowledge concerning the effects ... -
Contribution to unravel variability in bowhead whale songs and better understand its ecological significance
(Nature, 2021-01-08)
Article
Accés obertSince the first studies on bowhead whale singing behaviour, song variations have been consistently reported. However, there has been little discussion regarding variability in bowhead whale singing display and its ecological ... -
Cross-sensory interference assessment after exposure to noise shows different effects in the blue crab olfactory and sound sensing capabilities
(Elsevier, 2023-05)
Article
Accés obertUnderwater noise pollution is an increasing threat to marine ecosystems. Marine animals use sound in communication and orientation processes. The introduction of anthropogenic noise in their habitat can interfere with sound ... -
Dataflow of underwater noise measurements: from OBSEA to EMODnet
(SARTI, 2018)
Article
Accés obertUnderwater noise has been significantly raising in the past decades due to an increment of human-related activities in the oceans such as shipping, industrial activities, seismic explorations, etc. These activities may ... -
Does exposure to noise from human activities compromise sensory information from cephalopod statocysts?
(2013-10-15)
Article
Accés restringit per política de l'editorialMany anthropogenic noise sources are nowadays contributing to the general noise budget of the oceans. The extent to which sound in the sea impacts and affects marine life is a topic of considerable current interest both ... -
Electronic upgrades on the second generation of an autonomous and portable cetacean auditory screening system
(2009)
Text en actes de congrés
Accés obertWhile noise is now considered a marine hazard that can directly affect cetaceans and induce a stranding, no clinical approach has yet introduced the detection of a possible hearing loss at a stranding site as a necessary ... -
Evidence of Cnidarians sensitivity to sound after exposure to low frequency underwater sources
(Macmillan Publishers, 2016-12-21)
Article
Accés obertJellyfishes represent a group of species that play an important role in oceans, particularly as a food source for different taxa and as a predator of fish larvae and planktonic prey. The massive introduction of artificial ... -
Farmed salmon show no pathological alterations when exposed to acoustic treatment for sea lice infestation
(MDPI, 2021-10-14)
Article
Accés obertThe use of bioacoustic methods to address sea lice infestation in salmonid farming is a promising innovative method but implies an exposure to sound that could affect the fish. An assessment of the effects of these techniques ... -
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 ... -
Listening to the Deep: Live monitoring of ocean noise and cetacean acoustic signals
(2011)
Article
Accés obertThe development and broad use of passive acoustic monitoring techniques have the potential to help assessing the large-scale influence of artificial noise on marine organisms and ecosystems. Deep-sea observatories have ... -
Machine and deep learning approaches to localization and range estimation of underwater acoustic sources
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Comunicació de congrés
Accés restringit per política de l'editorialThis paper introduces ongoing experiments and early results for the underwater localization and range estimation of acoustic sources. Beyond classical results obtained for direction of arrival estimation, results concerning ... -
Marine mammal acoustic detections in the Greenland and Barents Sea, 2013 – 2014 seasons
(Nature, 2018-12-01)
Article
Accés obertWhile the Greenland and Barents Seas are known habitats for several cetacean and pinniped species there is a lack of long-term monitoring data in this rapidly changing environment. Moreover, little is known of the ambient ... -
Modelling the underwater noise associated to the construction and operation of offshore wind turbines
(2009)
Text en actes de congrés
Accés obertThe operation and in particular the construction of offshore wind converters induce considerable underwater noise emissions. It is assumed that small whales and seals can be affected by noise from machines and vessels, ... -
Morphological evidence for the sensitivity of the ear canal of odontocetes as shown by immunohistochemistry and transmission electron microscopy
(Nature, 2020-03-06)
Article
Accés obertThe function of the external ear canal in cetaceans is still under debate and its morphology is largely unknown. Immunohistochemical (IHC) analyses using antibodies specific for nervous tissue (anti-S100, anti-NSE, anti-NF, ... -
