A critical period of susceptibility to sound in the sensory cells of cephalopod hatchlings
(2018-01-01)
Article
Open AccessThe cephalopod statocyst and lateral line systems are sensory organs involved in orientation and balance. Lateral lines allow cephalopods to detect particle motion and are used for locating prey or predators in low light ... -
A decade of underwater noise research in support of the European Marine Strategy Framework Directive
(2022-09-01)
Article
Open AccessUnderwater noise from human activities is now widely recognised as a threat to marine life. Nevertheless, legislation which directly addresses this source of pollution is lacking. The first (and currently only) example ... -
A novel approach to real-time range estimation of underwater acoustic sources using supervised machine learning
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference lecture
Open AccessThe proposed paper introduces a novel method for range estimation of acoustic sources, both cetaceans and industrial sources, in deep sea environments using supervised learning with neural networks in the contex of a single ... -
A second generation of an autonomous and portable auditory screening system for cetacean clinical and research purposes
(2009)
Conference lecture

Acoustic system for physical oceanography research in deep ocean
(SARTI, 2016)
Conference lecture
Open AccessMarine multichannel seismic (MCS) data, used to obtain structural reflection images of the Earth’s subsurface, can also be used in physical oceanography exploration. This method provides vertical and lateral resolutions of ... -
Acoustic tag tracking: first experiments
(SARTI, 2018)
Article
Open AccessNowadays, the use of autonomous vehicles for ocean research has increased, since these vehicles have a better cost/performance ratio than crewed vessels or oceanographic ships. For example, autonomous surface vehicles can ... -
Acoustic tracking of Nephrops norvegicus by networked moored hydrophones in a deep-sea no-take reserve of the North Western Mediterranean Sea
(2020-12-01)
Article
Open AccessKnowing the displacement capacity and mobility patterns of fished marine resources is pivotal to establish effective conservation management strategies in marine ecosystems. Accurate behavioral information of deep-sea ... -
An acoustic valve within the nose of sperm whales Physeter macrocephalus
(2014-04-01)
Article
Restricted access - publisher's policySperm whales Physeter macrocephalus emit impulsive sound signals in short series of rhythmic clicks (codas) for communication, and in long series of single acoustic events (usual clicks) for echolocation. Both click types ... -
An embedded passive acoustic device for realtime hydroacoustic surveys
(2017)
Conference report
Open AccessIn this paper, we provide a comprehensive description of cost-efficient, innovative and interoperable ocean passive acoustics sensors systems, developed within the European FP7 project NeXOS (Next generation Low-Cost ... -
An interoperable architecture for in situ ocean noise monitoring
(2021)
Conference report
Open AccessAnthropogenic noise in the oceans has been significantly raising in the past decades due to an increment of human activities, adversely affecting the marine habitat. In order to assess and limit this impact, the long -term ... -
Analysis and initial design of bidirectional acoustic tag modulation schemes and communication protocol
(2021)
Conference report
Open AccessAcoustic underwater tags are key devices to study marine animals and obtain information regarding their behaviour. This information is essential to increase our knowledge of oceanic species and implement efficient conservation ... -
Arctic anthropogenic sound contributions from seismic surveys during summer 2013
(2017-06-13)
Article
Open AccessStatoil deployed three acoustic recorders from fall 2013 to 2014 in the Arctic region as part of a broad scientific campaign. One recorder was installed in the Barentsz Sea south-east of Spitsbergen. Two other recorders ... -
Artificial sound impact could put at risk hermit crabs and their symbiont anemones
(Elsevier, 2023-11-20)
Article
Open AccessThe sea anemone Calliactis parasitica, which is found in the East Atlantic (Portugal to Senegal) and the Mediterranean Sea, forms a symbiotic relationship with the red hermit crab, Dardanus calidus, in which the anemone ... -
Best practices in management, assessment and control of underwater noise pollution
(2009-06-30)
Research report
Open AccessThe origin of this work can be found in the project ‘Effects and Control of Anthropogenic Noise in Marine Ecosystems’ in the part relative to legal initiatives. In the first phase of the Report on this Project (December ... -
