Deep sea diving enthusiast John Westwater, aka westh2o, set out on an underwater adventure with some friends at Moorea, French Polynesia (about 9 miles northwest of Tahiti) back in October 2011. What they all experienced was beyond what they could have imagined as they encountered a humpback whale singing a song. It was while exploring a “shark cleaning station” at about 40 to 75 feet underwater when they first heard a boisterous bellowing echoing through the waters.
Westwater managed to capture their exciting adventure on video, but says, “The recording does not do justice to the actual sound. Seriously some of those sounds vibrated my chest. I didn't realize whales had such a wide frequency of sound. Some were mid to hi frequency and some were very low.” He adds, “After he passed I was thinking will there be another one…It was the size of an underwater School Bus! The dive master said that this is a rare event. Only happens about 1 or 2 a year and he dives over 1500 dives a year.”
