When should we most beware of Jellyfishes? Large swarms of these jellyfish reach the coast when the sea temperature ranges between 28.2 and 30 degrees Celsius and during the full moon, according to a new study from the Department of Natural Resources and Environmental Management at the University of Haifa.
(From Science Daily)– The study reveals, for the first time, the link between sea temperature and the lunar cycle and the arrival of swarms of Jellyfish s along the coast of Israel. “It is possible that individual Jellyfish s will also reach the coast during other conditions, but we discovered that the most significant swarms arrive under the above conditions, the proof being that in such periods the number of blockages of the Electricity Company’s cooling facilities due to Jellyfish s have been incomparably greater than during other periods of the year,” said Avi Algazi, who works in the system management unit of the Israel Electric Corporation (IEC) and who conducted the research.
