Passive acoustic monitoring has become an important tool in fisheries and ecological studies and we know very little about fish sounds, particularly in the Pacific Ocean. There are less than 1000 species of fish that have been documented to produce sound, compared to the 30,000 fish species that exist in Lire la suite…
Many marine species have evolved to rely primarily on sound for underwater navigation, prey detection, and communication. Marine biologists and other ocean researchers listen to the sounds generated by marine animals, for example, to detect the presence of an endangered species or to study social behavior. In recent years, increasing Lire la suite…
Ketos is a software package for acoustic data analysis with neural networks. It was developed with a particular eye to detection and classification tasks in underwater acoustics. The first version of Ketos was released in April 2019. Ketos was developed by the MERIDIAN Data Analytics Team at the Institute for Lire la suite…
In Miami, US, a research team led by Dr. Neil Hammerschlag from the University of Miami’s Rosenstiel School of Marine and Atmospheric Science, is studying how coastal urbanization is affecting the distribution, movement, and health of coastal sharks. The study, known as the Urban Sharks project, is focusing on the Lire la suite…
Acoustic tracking is widely used by marine biologists to study the distributions and movements of fishes and marine mammals on time scales ranging from hours to months or even years. Highly powerful, the technique allows scientists to map the migration routes of salmon, or correlate the habitat use and movement Lire la suite…
Despite the increasing amounts of underwater acoustic data that become available every day, only a small proportion is actually labelled. MERIDIAN is developing a crowdsourcing platform for labeling datasets, which can then be used to train machine learning models. The platform will allow users to create labeling sessions for their Lire la suite…
