What was the Bloop?

Imagine screaming so loud that someone hears you on the exact opposite side of the country! In the summer of 1997, scientists using super-sensitive underwater microphones called hydrophones recorded an incredible sound deep in the ocean. It was so loud it traveled over 3,000 miles underwater. They called it the Bloop! But what made this mysterious noise? The sound was significantly louder than a blue whale—the loudest animal on Earth. Because the sound waves looked organic, people everywhere started to wonder: was there a giant, undiscovered sea monster lurking in the deepest, darkest depths near Antarctica? For years, the Bloop was one of the ocean's greatest unsolved mysteries! Join Mira and Finn as they dive into this thrilling deep-sea detective story! You will learn all about the secret underwater SOFAR channel, how the Navy spies on the ocean floor, and the epic final reveal of what the Bloop actually was (hint: it involves snapping glaciers and massive icequakes!). Get ready to hold your breath and plunge into the watery unknown!
