# Buoyant Jellyfish Repellents The Ocean Guard Wards Off These Pesky Stingers in Swimming Areas By Amelia Roblin | Published 2012-10-11 | Unique Source: Trend Hunter, https://www.trendhunter.com/trends/ocean-guard References: [yankodesign](http://www.yankodesign.com/2012/10/10/jellyfish-ahoy/) & [idsa.org](http://www.idsa.org/) 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](https://www.trendhunter.com/trends/smart-buoy), 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](https://www.trendhunter.com/trends/public-safety-initiative) of its presence. Ultra low-frequency sound waves are emitted from the Ocean Guard that encourage [jellyfish to stay away](https://www.trendhunter.com/trends/the-hydra-pads). 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. ## Trend Insights (Trend Hunter) - Score: 2.0/10 - Popularity: 11% | Activity: 41% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Gen Alpha, Millennial, Gen X - Top markets: North America, South America, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Unique](https://www.trendhunter.com/unique) > [Inventions](https://www.trendhunter.com/inventions) ## Key Themes ### What's Driving This Trend - **Buoyant Jellyfish Repellents:** Developing new technology to prevent jellyfish stings in swimming areas. - **Low-frequency Sound Waves:** Incorporating ultra low-frequency sound wave technology in marine conservation efforts. - **Marine Creature Deterrence:** Creating new devices to ward off dangerous or harmful marine animals ### Who This Affects Most - **Travel and Tourism:** Industries could look into incorporating the device to their beach resorts to provide a safer environment for swimmers. - **Environmental Conservation:** Organizations who seek to protect the oceans from harmful marine creatures may look into using new technologies like the Ocean Guard in their conservation efforts. - **Water Recreation:** Companies operating water-based recreation activities may consider using the device to prevent accidents and maintain customer safety. ## Related on Trend Hunter - [Jellyfish-Inspired Interactive Robots](https://www.trendhunter.com/trends/jellyfish-robot.md) - [Mosquito-Repelling Miniature Diffusers](https://www.trendhunter.com/trends/vesperguard.md) - [Interactive Jellyfish Exhibits](https://www.trendhunter.com/trends/jewels-of-the-sea.md) - [Self-Propelling Controlled Buoys](https://www.trendhunter.com/trends/usafe.md) - [Modern Desk-Friendly Jellyfish Tanks](https://www.trendhunter.com/trends/pet-jellyfish.md) - [Lifesaving Swimming Vests](https://www.trendhunter.com/trends/swimming-vest.md) - [4-in-1 Mosquito Repellants](https://www.trendhunter.com/trends/moziguard.md) - [Rechargeable Bug-Repelling Devices](https://www.trendhunter.com/trends/mosquito-repellent-device.md) - [Electronic Mosquito Repellents](https://www.trendhunter.com/trends/electronic-mosquito-repellent.md)
