A team of professionals at Merinov relied on the use of a thermal camera in order to detect marine mammals at the surface of the water. One of the main uses of the thermal camera is night vision. Since this device captures infrared rays rather than visible light, there is no difference between a picture taken during the day or at night, apart from a slight decrease in surface temperatures after the sun sets. Merinov believes that an efficient marine mammal infrared detection system could be beneficial in many sectors of activity in Canada. (In Journal of Ocean Technology, vol. 14, no 3. 2019).
