Robots To Fight the Jellyfish Invasion

Last weekend, the world’s largest boiling-water nuclear reactor, Sweden’s Oskarshamn plant, was paralyzed after a bloom of moon jellyfish clogged plant’s cooling systems, forcing it to shut down.

Jellyfish blooms — the term for giant swarms of jellyfish — have also been responsible for nuclear shut downs in California, Florida, Israel, Scotland, India, and Japan, where one plant has reported removing as much as 150 tons of jellyfish from its system in one day.  Jellyfish are truly taking over the oceans.  In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change.
