SEATTLE, June 12 (UPI) -- U.S. scientists have launched the first buoy designed to monitor ocean acidification.
The 10-foot-diameter buoy, part of a National Science Foundation grant awarded to the University of Washington and Oregon State University, was launched in the Gulf of Alaska to measure air-sea exchange of carbon dioxide, oxygen and nitrogen gases.

The buoy is anchored in water more than 16,400-feet deep. Once it hit the water, the buoy began to transmit data via satellite.
The goal of the research, which includes scientists at the National Oceanic and Atmospheric Administration's Pacific Marine Environmental Laboratory, Fisheries and Oceans Canada and the Institute of Ocean Sciences in Sidney, British Columbia, is to determine how much carbon dioxide the North Pacific Ocean absorbs each year.
