Millions of dollars worth of herring float dead Tuesday in Kolgrafafjordur, a small fjord on the northern part of Iceland's Snaefellsnes peninsula. Between 25,000 and 30,000 tons of fish died in December and more now, due to lack of oxygen in the fjord thought to have been caused by a landfill and bridge constructed across the fjord in December 2004. Ten thousand tons of herring has a current export value of $ 9.8 million, according to Morgunbladid newspaper.
