Hundreds of tonnes of herring run aground in Iceland
The Kolgrafarfjörður fjord on the west coast of Iceland is currently full of herring. The Icelandic Marine Research Institute estimates that there are currently 285 thousand tonnes of herring in the fjord. For unknown reasons, at least several hundred tonnes of them have swum up onto the coast and died. Currently the dead fish cover an area of roughly 1 square kilometer.
Researchers are taking samples and hoping to find the causes, but several unusual conditions might be at play. Perhaps, due to the enormous amount of fish in the small fjord, there is a lack of oxygen in the sea. Another cause might be the recent calm, but very cold weather which could be making the sea water in the small fjord unusually cold. The herring may then be trying to escape the cold, unable to navigate out of the narrow fjord.
