Humpback whales have one of the most remarkable migration patterns on the planet. During the summer months, they feast in Alaska’s nutrient-rich, icy waters to bulk up for their journey. Then, as winter approaches, they embark on an incredible migration to Hawaii’s warm tropical seas. ❄️ This migration is nearly 3,000 miles / 4800 km! Research activities authorized under NMFS/MMPA ESA Permit #21321 following all guidelines. The UAS pilot holds FAA Part 107 authorization. #pacificwhalefoundation

Blue whale vocalizations are very low frequency sounds with some in the 15 Hz range. These tones characteristically travel long distances due to the high power, but also due to very long-wavelengths (over 300 feet for 15 Hz). This enables their songs to be heard thousands of miles from the source. We can assume that the projection distance is important (Nature can be extravagant, but she is never wasteful), but we can only speculate why they need to broadcast their songs across ocean basins.
