An Alaska-based project has found salmon spawning in the Arctic Ocean watershed, suggesting that climate change is pushing certain salmon species into new areas. “In the Arctic, the water is getting warm enough and they’re starting to blink on.”To do the research, scientists studied 100 chum salmon on two rivers on Alaska’s North Slope, the Arctic part of the state. The Anaktuvuk and Itkillik rivers flow into the Colville River, which empties into the Arctic Ocean. The researchers noticed the conditions were similar to where salmon reproduce in the their usual habitats. The scientists are also analysing salmon bone and tissue to see if they’ve been in Arctic waters their whole lives.
