The inhabitants of Troms could hardly believe their eyes on the morning of New Year's Eve, a very large amount, an estimated 10 to 20 tons of dead herring washed up on the beach, writes Northern Lights. Tromsø city is the ninth largest urban area in Norway by population. The city is warmer than most other places located on the same latitude, due to the warming effect of the Gulf Stream which originates at the tip of Florida. Various theories abound for the incident but no one knows for sure what's happened in the popular hiking area in Nordreisa municipality.

However, various theories have been tossed around, explains Jan-Petter Jorgensen (44), who stumbled upon the mass death in sight on the beach with his dog Molly. People say that something similar happened in the 80′s, and there is speculation among others on the river which flows into the ocean behind a promontory on the site, may have had something to do with it. Maybe the fish have been caught in a deprived oxygen environment, and then died of fresh water? Jorgensen estimates each individual fish to be of 100-150 grams, and that the total might be about up to 20 tons. Now he's worried about what might happen if no one comes and removing carcasses.
