Fellow of the American Geophysical Union
Biologically produced gases in the surface ocean are present in the atmosphere at very low levels, but they have a major impact on global atmospheric cycling of elements such as sulfur, nitrogen, and carbon. Some trace gases can also influence the climate system by influencing greenhouse gas lifetimes, stratospheric ozone, and cloud properties. My research group develops analytical instruments to detect trace gases, measures the abundance of trace gases on ships and islands, and uses computer simulations to understand rates and pathways by which gases cycle through the atmosphere. We also study long term changes in atmospheric composition due to changes in climate and man's activities. We reconstruct the changes in atmospheric composition over many thousands of years by analyzing the trace gases in ancient air trapped in polar ice cores from Greenland and Antarctica.
