Great Bear Hydrophone network

The GBHN is a long-term monitoring program that can detect important but unseen changes in our marine ecosystems, such as increasing human-caused noise emissions and changes in cetacean habitat use over time. The program fills an important gap between hydrophone networks to the north (Cetacealab) and south (Orcalab). This area is home to several species that are listed under Canada’s Species at Risk Act including humpback whales, Northern Resident and Bigg’s Killer Whales.
