Use of blue whale acoustics for finding the ocean secrets
Date 21/03/2026 Learning from a webinar Today on 21st March 2026, in the evening between 7:30–8:45, I got an opportunity to attend a webinar on ‘Movement ecology and conservation of blue whale in the central California current ecosystem’, which was delivered by Dr. John Ryan from Monterey Bay Aquarium Research Institute (MBARI) and organized by the Marine Mammal Research & Conservation Network of India (MMRCNONOI). After a long time, I successfully attended this full live webinar from start to end. Overall, this webinar was impressive to listen to and learn inside about blue whale research, which was more focused on a few important topics, including coastal upwelling, low frequency sound, krill, bimodal distribution and their foraging call, D-Call, and bio-logger or tag for blue whale. Coastal upwelling is an oceanographic concept which means that because of the wind, the dense, colder and nutrient-rich water from the bottom of the ocean moves from bottom to surf...
