A place where everyone shares your joy and frustration with scientific data analysis in Python and R PyBaR is an informal co-working group organized by MERIDIAN, which provides students and researchers at Dal with a space to discuss data analysis problems and computational challenges related to their research. PyBaR focuses Lire la suite…
On August 16 and 17, 2018, our first MERIDIAN workshop entitled “The Canadian Ocean Soundscape: Models, Tools and Integration Points” took place at the Atlantica Hotel in Halifax, Nova Scotia. It brought together members of the geographically disperse MERIDIAN team and various representatives of the Canadian ocean acoustics community. The Lire la suite…

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…
MERIDIAN is working with JASCO to design a tool for visualizing underwater acoustic data with a directional component that indicates bearing for use by biologists and other researchers. This system will visualize data collected from hydrophone arrays that are capable of discerning the bearing of sound sources, which can help Lire la suite…
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 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…
