Special Issue Information

Dear Colleagues,

Passive acoustic monitoring is becoming an important tool to study the ecosystem thanks to technologies improvements, to high temporal resolution, relatively low cost and time effort, and zero impact on environment and animal behavior.

Analysis of long acoustic data series is a challenge and each ecosystem has its own soundscape signature changing with time, for example following the day-night cycle or alternation of seasons, and along the multidimensional space (vertically, horizontally). Some dominant physical and biological components of the soundscape are known but we need to better understand the acoustic ecosystem, collecting more data and improving the automatic analysis, also applying data analysis techniques already used in other field over bioacoustics.

Rapid reviewing and publication turn-around for high-quality contributions is ensured, with scope relating (though not limited) to:

  • Soundscape temporal and spatial patterns
  • Soniferous species presence and abundance
  • Impact of noise on soundscape
  • Masking effect
  • Physical, biological and human drivers of the soundscape
  • Climate change, i.e. ice calving and ice melting impact on soundscape
  • Signal detection technique
  • New techniques of long time series recordings and analysis

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The evaluation of acoustic temporal rhythms in wide-ranging cetaceans can reveal patterns in animal spatial presence and the occurrence of periodical phenomena. Here, we aimed at assessing the temporal patterns of dolphin’s acoustic presence in a shallow-water area in the Sicily Strait (Mediterranean Sea). Whistles were collected continuously for 14 months from an acoustic monitoring station installed aboard of an elastic seamark. Over a total of 6955 h of recording, 14,048 signals were identified using both automatic and visual methods. Three parameters were analyzed: hourly presence (HP), used as a proxy of the presence of dolphins in the area; detection rate (DR), indicating the acoustic activity rate of dolphins measured per hour in the entire dataset; and detection rate in presence of dolphins (DRD), indicating the acoustic activity rate of dolphins considering only the hours when whistles were recorded. The highest values of both HP and DR were reached during the night, and the Autumn and Winter months, suggesting an increase in the dolphin’s occurrence and a possible moving away and towards the monitoring station potentially following prey. DRD, instead, showed an almost uniform distribution throughout the day implying that when the animals are close to the monitoring station, the acoustic activity does not show any pattern. However, possible changes in the communication exchange along the seasons were suggested. This study complements other work on this subject, improving the knowledge of dolphins’ acoustic activity in the area. Full article
