Buoyant Jellyfish Repellents

The Ocean Guard Wards Off These Pesky Stingers in Swimming Areas

Jellyfish are responsible for a great many cases of harming humans every year, prompting the invention of contraptions like the Ocean Guard. This innovative drifting device is designed for placement around designated swimming spots offshore, ensuring that any encroachments of the deadly marine creature are almost entirely prevented.

The apparatus takes the form of a vertical pole surrounded by a lifesaver ring. This enables it to bob on the surface of the sea and remain visible from the beach, informing lifeguards and the public of its presence. Ultra low-frequency sound waves are emitted from the Ocean Guard that encourage jellyfish to stay away.

The concept was conceived by Bao Haimo, Kyung-Chan Han, Dong-Woo Kang, Kyung-Hong Kim, Jung-Hoon Yang, Kyung-Rok Kang and Minji Jeon and won them an IDSA Award.
