"SEWARD, Alaska — In the cold, choppy waters of Alaska’s Resurrection Bay, all eyes were on the gray water, looking for one thing only.

It wasn’t a spout from humpback whales that power through this scenic fjord, or a sea otter lazing on its back, munching a king crab.

Instead, everyone aboard the Nanuq, a University of Alaska Fairbanks research vessel, was looking where a 5-foot (1.52-meter) long, bright pink underwater sea glider surfaced.

The glider — believed to be the first configured with a large sensor to measure carbon dioxide levels in the ocean — had just completed its first overnight mission."
