Some of the lenses that were placed after KNM helge Ingstad collided with a tanker and sank with floating elements with polystyrene. As they went out for many weeks, some of the lenses had opened holes and the small polar balls were scattered around the area, writes Bergens Tidende.
"This is the first time we have experienced this, and for the first time we have been so elevated in an area with so severe weather conditions.
To remove small plastic balls, 20 young people like summer work need to sew the coastline and surrounding areas and vacuum what they find.
"We use a sheet blower, a vacuum cleaner, and sometimes our fingers to pick them up," says Ida Eide of the cleansing work in the archipelago.
So far, they have found polar balls in a 500-meter wide area that extends to 50 meters on land.
It is estimated that up to now we have received about 600 liters of debris and polystyrene, says John Goethe Haug in a firearm and rescue Øygarden, which helps coordinate cleaning.
