Passive Acoustic Monitoring

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 Read more…

Data Discovery Portal

Underwater acoustic data is important for understanding the oceans and how sound affects the marine environment. To record underwater sounds produced by, for instance, marine mammals, waves, and ships, and to capture the complexity and interactions of the marine soundscape, hydrophones and other acoustic recording devices are used. These devices Read more…

Ocean Soundscape Atlas

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

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…

CIOOS_SIOOC Metadata Working Group

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…
