个人简介
His research focuses on atmospheric composition, the carbon cycle, and climate change. He is considered a leading investigator of the global oxygen cycle for his precise measurements and analysis techniques. Keeling developed his method for measuring atmospheric oxygen levels utilizing interferometry techniques in the laboratory. He began pioneering measurements of changes in atmospheric oxygen levels from air samples collected at stations around the world. The measurements continue at nine sampling stations, extending from Ellesmere Island in northern Canada over the equator to two Antarctic stations.
Measurements from his group show that the atmosphere O2 is decreasing at a small but measurable rate due primarily to the burning of fossil fuels. From 1991 to 2011, the atmosphere lost on average 19 out of every million O2 molecules in the atmosphere. Establishing this rate was a milestone for improving our understanding of the processes controlling the buildup of CO2 in the atmosphere.
Research Interests
Measurements of variations in atmospheric oxygen
Recent perturbations to the global carbon cycle
Air-sea gas exchange
Detection of ocean heat storage and transport using atmospheric gases
Paleoclimate theory
