This year’s commercial harvest of chum salmon in Kotzebue Sound was nearly 700,000 fish, breaking a record nearly four decades old. To the south, the value of the commercial salmon catch in Norton Sound was also the highest ever.
Scientists have spent the past few decades catching up to traditional knowledge, documenting scientifically what whale hunters already knew. Like the fact that the whales can smell, and that they can travel under sea ice.
When golden eagles migrate to and from Alaska each year, they have to fly around a huge obstacle: the 16,000-foot peaks of the Wrangell Mountains. Some of the eagles choose a route that skirts the northern edge of the mountains. Others go south. A new study examined how the weather affects which way the eagles fly.
“Unless the underlying problem of climate change is addressed, the sea ice is expected to continue to diminish,” said polar bear researcher Eric Regehr. “And at some point that will likely have a negative effect on the bears in this Chukchi area.”
