How Arctic Fish Might Benefit From Shrinking Ice
As polar ice disappears, predatory fish that hunt by sight may get a major boost, a new model suggests.
As Arctic ice shrinks, fish will see the region in a whole new light.
With sunlight now permeating previously darkened waters, predatory fish that hunt by sight are set to invade in increasing numbers, scientists predict in a new study.
Models of past and future climate and environmental scenarios forecast a dramatic rise in light-penetrating polar waters from 2040 onward. (Related: "Extreme Research Shows How Arctic Ice Is Dwindling.")
“We know that sea ice extent and thickness is declining and is predicted to continue to do so,” says study leader Øystein Varpe of the University Centre in Svalbard, Norway.
“With that, there comes a dramatic increase in light entering the water column because ice, and particularly snow-covered ice, are good at
