Underwater noise generated by human activities such as shipping raises concerns about its potential impact on marine life, for instance, by affecting their ability to navigate, communicate, feed, and reproduce. With increased shipping activity along traditional routes and the opening of new shipping lanes, changes in noise distribution in Canadian Read more…
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 Read more…
The recently established Canadian Integrated Ocean Observing System/Système Intégré d’Observation des Océans du Canada (CIOOS/SIOOC) is a national effort to facilitate the knowledge exchange in ocean sciences and to make oceanographic data from various public, private and academic stakeholders discoverable and accessible to the end-user. It is an initiative that Read more…
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 Read more…
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 Read more…
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 Read more…
