CCPO Lecturer to Assess Impact on Ocean of Manmade Iron Emissions
Pete Sedwick, an Old Dominion University oceanographer, will deliver the lecture, "Human Impact on the Atmospheric Input of Iron to the Surface Ocean," at the ODU Center for Coastal Physical Oceanography, 3:30 p.m. on Monday, April 11.
The lecture, which is free and open to the public, will be in Room 3200 of the Research Innovations Building 1 in University Village. A reception with refreshments begins at 3 p.m.
Sedwick is an associate professor in ODU's Department of Ocean, Earth and Atmospheric Sciences.
His lecture will explore the role of iron in limiting phytoplankton growth in the ocean and the potential effect of anthropogenic inputs of this limiting nutrient on altering controls on phytoplankton production. He will use data from Bermuda, Greenland and Antarctica to argue that anthropogenic combustion emissions constitute a significant source of highly-soluble aerosol iron, such that human activities are perturbing the availability of this essential micronutrient, and possibly other bioactive trace elements, in the surface ocean.
Sedwick joined ODU in 2008 after serving as an associate research scientist at the Bermuda Institute of Ocean Sciences for seven years.
