Trash in the fjords? Norway turns to drones

Oslo

NORWAY's fjords have long inspired the country's artists and drawn streams of tourists. In winter, their ice-laced surfaces shimmer beside snow-capped mountains: a vision of natural beauty, blissfully untouched.

But lost in the depths of the fjord in Oslo, stretching out from the capital, is a trove that would please any intrepid archaeologist or Nordic noir sleuth: sunken Viking trinkets, bullion from Hitler's prized warship and, possibly, a few victims of homicide.
