Feeling anxious today? Take a trip with us under the sea, and watch divers follow a whalesong to a mysterious and awe-inspiring close-up brush with a humpback whale.

The whalesong alone was worth the price of admission, writes one of the divers:

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.

Grist thanks its sponsors. Become one.

And then seeing the whale, which he described as being the size of a school bus … well, it’s hard to imagine having this experience and not coming away with an increased reverence for all of Earth’s creatures. Unless you’re a krill, anyway.
