An ocean first: Underwater drone tracks CO2 in Alaska gulf


Still Waters

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.
