Detlev Helmig, principal investigator

Institute of Arctic and Alpine Research
University of Colorado, Boulder

Detlev is the primary investigator on this project.  He has studied biosphere-atmosphere trace gas fluxes and their environmental controls all over the world, including projects in Antarctica, the Azores, and Greenland. The picture shows him at the South Pole, conducting experiments on ozone fluxes between the air and the snowpack that helped prepare for similar studies at sea.

Laurens Ganzeveld, research scientist

Department of Environmental Sciences
Wageningen University and Research Centre
Wageningen, The Netherlands

Laurens is figuring out how the data from this project can contribute to better models of atmospheric chemistry for the whole world. He is shown here at Niwot Ridge, Colorado, helping gather data in a blizzard.

Chris Fairall, research scientist

National Oceanic and Atmospheric Administration
Boulder, Colorado

Chris heads up the Clouds, Radiation, and Surface Processes Division at NOAA. He is interested in fluxes between air and sea and between air and ice. This photo is from a trip on the research vessel Ron Brown in 2001.

Kathrin Lang, student

Potsdam University, Germany

Kathrin is a chemistry student visiting INSTAAR in Colorado this year. She began working on the project in March 2007. This photo was taken on a research cruise in summer 2007 -- Kathrin is going to and write a thesis using the data collected.

Jacques Hueber, professional scientist

Institute of Arctic and Alpine Research
University of Colorado, Boulder

Jacques built the first version of the ozone analyzer, working with reels of wire, circuit boards, and canisters of nitric oxide. He is shown here working with a similar instrument mounted on Niwot Ridge in the Rocky Mountains.

Ludovic Bariteau, research associate

Cooperative Institute for Research in Environmental Sciences (CIRES)
National Oceanic and Atmospheric Administration
Boulder, Colorado

Ludovic often goes on research cruises with the ozone analyzer to gather and process the data. After finishing a master's degree in France three years ago, Ludovic began working for NOAA. He is thinking about going back to school for a Ph.D., probably at the University of Colorado so that he can stay near the mountains.
