The study of marine soundscapes is an emerging field research that contributes important information about biological compositions and environmental conditions. seasonal circadian soundscape trends a protected area (MPA) in the Mediterranean Sea have been studied for one year using autonomous acoustic recorder. Frequencies less than 1 kHz are dominated by noise generated waves louder during winter; conversely, higher frequencies (4-96 kHz) snapping shrimp, which increase their activity at...
Dolphins emit short ultrasonic pulses (clicks) to acquire information about the surrounding environment, prey and habitat features. We investigated Delphinidae activity over multiple temporal scales through detection of their echolocation clicks, using long-term Passive Acoustic Monitoring (PAM). The Istituto Nazionale di Fisica Nucleare operates multidisciplinary seafloor observatories in a deep area Central Mediterranean Sea. Ocean noise Detection Experiment collected data offshore Gulf...
Acoustic noise levels were measured in the Gulf of Catania (Ionian Sea) from July 2012 to May 2013 by a low frequency (< 1000 Hz) hydrophone, installed on board NEMO-SN1 multidisciplinary observatory. is cabled node EMSO-ERIC, which was deployed at water depth 2100 m, 25 km off Catania. The study area characterized proximity mid-size harbors and shipping lanes. Measured correlated with passage ships tracked dedicated AIS antenna. Noise power range between 10 Hz Hz. Experimental data compared...
Abstract An understanding of the population dynamics and social organization cetaceans is essential to manage influence anthropogenic activities. In this study, size, site fidelity interactions bottlenose dolphins in Strait Sicily (Italy) were investigated provide recommendations for their conservation. Mark‐recapture analysis was based on encounter histories 103 marked from 2004 2015. The POPAN formulation Jolly–Seber model MARK software used estimate size super‐population. Site estimated...
Many gregarious species require complex patterns of communication for maintaining coordinated behaviors, articulated social structure and group cohesion. In mammal species, complexity has been considered the driving force development advanced acoustic systems. Striped dolphins are highly social, showing large size with females strong bonds kin. Here, we tested hypothesis that more pattern plays a key role in activity striped dolphins. The production rate clicks, whistles burst pulses,...
Abstract Dolphins interact with many types of fishing gear, causing damage to activities and in some cases facing harm becoming entangled as bycatch. In this study, the behaviour bottlenose dolphins during their interaction set nets, equipped without interactive pingers, was investigated. Acoustic monitoring nets conducted for a total 56 hauls 814.9 hr recordings, from 16 October 13 November 2015, along coast Lampedusa island (Sicilian Channel, Italy, Mediterranean Sea). The level between...
In this study, underwater noise from a full-scale wave energy converter system (ISWEC), installed on the coast of Pantelleria Island (central Mediterranean Sea), was characterized. The measured using an autonomous acoustic recorder anchored to sea bottom 40 m ISWEC hull. Acoustic monitoring continued for 15 months, starting 7 months before (PRE), 2 during (INST) and 6 after installation (POST). levels noise, assessed with power spectrum density octave third-octave band sound pressure...
Landfilling should be the last option in an integrated Municipal Solid Waste (MSW) management approach. In European Union (EU), policy framework to protect environment and public health against impact of hazards related urban solid waste has been consistently implemented recent decades. A growing interest negative fires landfills on people's was reported some countries. Italy, increasing occurrence arsons MSW years. During summer 2012, a multi-site arson occurred Palermo landfill Bellolampo...
Abstract When implementing conservation strategies involving passive acoustic monitoring, an accurate description of signal properties is crucial, especially when studying threatened and elusive vocalizing species. Misrepresentation detected sounds can result in information loss or misclassification species, thus compromising the management process. Distortion time–frequency features depends on characteristics propagation through sea water, sensitivity sampling frequency acquisition system...
The seismic water gun is widely used and plays an important role in seabed imaging acquisition; however, acoustic impacts on marine organisms are currently poorly understood. aim of this study was to analyse the biochemical responses peristomial membrane (PM) sea urchin, Arbacia lixula, when exposed shots open water. PM (located around mouth) involved vital functions, such as nutrition protection. Individuals urchins (n = 7 for each time slot) were sampled before, at end, intervals 3 h 24...
Abstract In this study we analysed the acoustic properties and presence of haddock calls in Arctic fjord Kongsfjorden (79° N–12° E, Svalbard Islands, Norway) one year. Data were collected with three autonomous recorders located inner, middle, outer parts fjord. The is characterized by a gradient oceanographic conditions from inner to part, reflecting changes Atlantic waters. Haddock sounds more abundant than middle fjord, whereas they absent at site. Mainly open-water site, call abundance...
Dolphins emit a large variety of acoustic signals on which they rely for navigation, communication and searching food. Nevertheless, each species uses quantitative qualitative species-specific characteristics tonal pulsed signals, the different behavioral contexts may affect use these signals. The main aim this work is to evaluate if emission rate can be used as cue recognize species, an intra-specific feature recognizing contexts. We collected data during 27 sightings bottlenose striped...
In response to public health concern about effects of arson at solid waste management plants in July 2012, we analysed vital statistics data evaluate any potential effect on pregnancies different gestational ages pollutants emitted from the landfill fire.A community living near largest plant Sicily.The study group comprised 551 births, live births and stillbirths mothers residing extra-urban exposed area, conceived during a 40 week period which highest fire's peak might have influenced...
Abstract Underwater acoustic monitoring combined with real-time sea surface observations and numerical model forecasts could improve the efficiency of natural anthropogenic sound source discrimination. In this work, pressure levels at different frequencies were compared significant wave heights, measured using an X-band radar system, then matched against independent data derived from a Simulating Waves Nearshore (SWAN) in order to confirm their reliability. The recorded fixed buoy located...
The EMSO Research Infrastructure operates multidisciplinary seafloor-cabled observatories in a deep-sea area offshore Eastern Sicily (2100 m of depth). In data-lacking zone, Passive Acoustic Monitoring activities revealed new information on cetacean bioacoustics over multiple ecological scales. Expert operators investigated the presence vocalizations within large acoustic datasets acquired. Then, algorithms were developed to provide behavior and ecology recorded species. 2005-2006, activity...
