An ocean first: Underwater drone tracks CO2 in Alaska gulf

Within the chilly, uneven waters of Alaska’s Resurrection Bay, all eyes have been on the grey water, searching for one factor solely. It wasn’t a spout from humpback whales that energy via this scenic fjord, or a sea otter lazing on its again, munching a king crab.

As an alternative, everybody aboard the Nanuq, a College of Alaska Fairbanks analysis vessel, was wanting the place a 5-foot (1.52-meter) lengthy, shiny pink underwater sea glider surfaced.
The glider — believed to be the primary configured with a big sensor to measure carbon dioxide ranges within the ocean — had simply accomplished its first in a single day mission.
Designed to dive 3,281 toes (1,000 meters) and roam distant components of the ocean, the autonomous automobile was deployed within the Gulf of Alaska this spring to offer a deeper understanding of the ocean’s chemistry within the period of local weather change. The analysis could possibly be a significant step ahead in ocean greenhouse fuel monitoring, as a result of till now, measuring CO2 concentrations — a quantifier of ocean acidification — was principally carried out from ships, buoys and moorings tethered to the ocean ground.
“Ocean acidification is a process by which humans are emitting carbon dioxide into the atmosphere through their activities of burning fossil fuels and changing land use,” mentioned Andrew McDonnell, an oceanographer with the School of Fisheries and Ocean Sciences on the College of Alaska Fairbanks
Oceans have carried out people an enormous favor by taking in a few of the C02. In any other case, there can be far more within the environment, trapping the solar’s warmth and warming the Earth.
“But the problem is now that the ocean is changing its chemistry because of this uptake,” mentioned Claudine Hauri, an oceanographer with the Worldwide Arctic Analysis Heart on the college.
The big quantity of information collected is getting used to review ocean acidification that may hurt and kill sure marine life.
