COASTAL TIDINGS Ove Increased Atmospheric Nitrogen Parallels Harmful Algal Blooms vex the last three decades, the amount of atmospheric nitrogen polluting North Carolina waters and other parts of the North Atlantic Ocean Basin has increased significantly and parallels harmful algal blooms, according to a new study. North Carolina Sea Grant researchers found that nitrogen in the air accounted for 46 to 57 percent of the total nitrogen newly deposited in the nitrogen-sensitive North Atlantic Ocean Basin. The increase can be attributed to growing agricultural, urban and industrial emissions of nitrogen oxides and ammonia, and possibly organic nitrogen. 'The study is significant because it reconfirms that atmospheric nitrogen has been found to be a regional and global source of pollution," says Hans Paerl, North Carolina Sea Grant research scientist and Kenan professor of marine and environmental sciences at the University of North Carolina at Chapel Hill (UNC- CH) Institute of Marine Sciences. "We also found a strong spatial linkage between water in areas with high amounts of atmospheric nitrogen and in places where there have been documented increases in harmful algal blooms. This is critical as we are only beginning to understand the importance of links between human-induced pollution of coastal oceans and harmful algal bloom ; Joume/s End Photo by Michael Halminski Autumn visitors to the Outer Banks will once again see the beacon of the historic Cape Hatteras light- house. The massive lighthouse was rolled 2,900 feet along a temporary rail system, ending its joumeyjuly 9. Although the beacon returned on Labor Day weekend, visitors must wait until Memorial Day 2000 to venture inside. Workers continue to secure the foundation at the new site. David Whitall, a UNC-CH graduate student, collaborated with Paerl on the report, published in the journal Ambio. Wh
