An "electronic nose" system capable of analyzing chemicals that stimulate the human sense of smell is being used in the search for the remaining victims of the April 16 ferry disaster.
The gadget can detect scents in the air or water through electronic sensors that react to certain chemicals.
The sensor detects scents from 500 ml of water sample taken from the search area. Divers searching for the remaining victims of the Sewol ferry collected 600 ml samples of water from 39 locations in the sunken ferry earlier this month where missing passengers are believed to be trapped.
As similar patterns were found on six samples, thorough searches were conducted at the locations where the samples were taken, but to no avail.
The electronic nose belongs to a Korean research agency, but search officials declined to say exactly where it comes from.
