Researchers with the National Oceanic and Atmospheric Association Administration are hoping that data from a July study off the mid-Atlantic coast of the U.S. will show how far airborne chemicals that contribute to acid rain are reaching offshore. NOAA obtained comparative air and sea-surface measurements of sulfur, nitrogen, and other trace gases and particles.
A research aircraft flew from Newport News, Va., and then from Bermuda to collect measurements. On each of the plane's flights it rendezvoused with the NOAA research ship Mt. Mitchell, which was collecting samples between Norfolk and Bermuda. The instruments operated “the way they were supposed to,” according to Joe Boatman of NOAA's Air Resources Laboratory in Boulder, Colo.
