New Online Learning Resource Listens to Orcas
Overview
As students in BC and across Canada return to school, Ocean Networks Canada (ONC) and Open School BC (OSBC) are delighted to announce the release of *Shouting Whales*, a new marine science educational resource for teachers and educators, that is available free of charge. Aimed at middle school students from grades six to eight, *Shouting Whales* is a unique resource that brings together science, problem-based learning, multimedia, and advocacy for an in-depth exploration of the oceanic soundscape. # Exploring noise pollution beneath the surface of the sea In particular, students are asked to think about the ocean from the perspective of the orca whale, an animal that relies on sounds rather than visual cues. Through the activities outlined in this resource, students will explore the properties of sound, learn how scientists are studying ocean noise and come to understand how increasing noise pollution is threatening the orca whale’s way of life.

Using AI to detect orcas in the Salish Sea
Overview
A near real-time orca detector using sound and acoustic context awareness is being developed for the Salish Sea, with potential uses including the identification of these mammals for vessels in the area. Fabio Frazao, [one of the first recipients of the $20,000 Roy Hyndman Ocean Observing Award](https://www.oceannetworks.ca/news-and-stories/stories/meet-the-first-recipients-of-the-roy-hyndman-award/), has completed his one-year project with Ocean Networks Canada (ONC). Using hydrophone data from ONC’s Victoria Experimental Network Under the Sea (VENUS) observatory, Frazao expanded upon his artificial intelligence (AI) algorithm to detect and classify orca sounds in the Salish Sea. Orcas make a wide range of sounds like whistles, echolocation clicks, and low-frequency pops, which can be mistaken for other marine mammals and masked by ambient underwater noises. The AI algorithm learned from thousands of these orca vocalizations and other sounds recorded from ONC’s hydrophone network deployed in the Salish Sea. The detector was then tested on 65 hours of acoustic data to detect and distinguish orca sounds.
