Long-distance champions of Alaska

A few years ago, Joly wondered if he could quantify an often-heard hypothesis that caribou were the animals that traveled farthest across the surface of Earth.

Rain falls, as it always has

“Chances are good that the drop of rain that splashes on your forehead is made of molecules that were here long before the first humans looked up in wonder at a cloudy sky, long before the first leafy plants stretched their roots into the soil, long before the first single-celled organisms took the critical step of dividing in half to reproduce.”

World traveler visits South Fairbanks

“I saw this black-and-white bird, smaller than my hand, its beak open, music pouring out. I remembered the blackpoll warbler making headlines a few years ago. Researchers had discovered that, in fall, after crossing North America from the far north, the birds leap off branches on the East Coast. They then fly thousands of miles over the open Atlantic Ocean on their way to South America.”

Postcards from a frozen icebreaker — Part 27

Polarstern is making slow progress as it tries to leave the ice. Funny how the ice has drifted so fast this year, and broken up so much. Yet it still has a firm grip on Polarstern. Not wanting to let her pass easily to the edge.

When permafrost kills? A moose story

While standing over the festering moose, Douglas points out meat on the animal’s ribs, along with internal organs undamaged, seeming proof that a hungry bear or wolf did not pull it down. There are no large animal tracks nearby in the mud. Did this northern sinkhole kill the moose?
