Ms Norman is using data from the Östergarnsholm site (a very well controlled site in the Baltic Sea) and the Galathea cruise to estimate the flux of carbon dioxide using different methods, Eddy correlation method and the inertial dissipation method. The purpose of the visit at DMU was to get information and learn more about the data from the Galathea cruise where Dr Sorensen was in charge of the measurements of carbon dioxide.
During the stay at DMU, she developed a method to make corrections of ship movement’s affect on her data, to be able to use the Eddy Covariance method, and is looking to apply a correction due to the delay of the accelerometer.  She also discovered that Kolmogorov constant can be higher for carbon dioxide than for other scalars, which is still to be investigated.   Attending a meeting with researchers, from Risø DTU, who are using the same Galathea data allowed her to learn more about their work and discuss future collaboration.
