Educational activities CENPERMs activities in 2018 include a number of educational efforts. These include both arctic field courses and classic university courses at the basic and advanced levels at the University of Copenhagen. In addition to course taught, a number of M.Sc. theses have been supervised (see Ongoing research projects).

Three papers below highlight the benefits of plot level based studies of volatile organic compound (VOC) production, mult budget for a typical and wide-spread heathlandtype ecosystem in Greenland. Two main results can be highlighted: (1) more than 13% of the carbon turnover measured as respiration occurs during the non-growing season and (2) the ecosystem is overall a weak C sink without any significant changes to be n Højdepunkter 2018 Højdepunkterne for CENPERM i 2018 omfatter tre eksempler på intensivt feltarbejde og laboratorie-inkubationer, samt hvordan disse to komponenter kan integreres i procesmodellering.

To hoved Revealing the tundras secrets from space by Mojtaba Karami, PhD student, CENPERM, University of Copenhagen Dozens of spaceborne platforms are currently imaging the earths surface, and this number is only expected to grow over the coming years. Using the wealth of data these instruments create, we c tion of these processes to be able to upscale them from the field level to larger extents, for example the entire landscape, region or the Arctic. Tools like fixed cameras, drones, and flux towers help us to gain highly detailed and reliable estimates of the landscapelevel dynamics, but they can do Publications & conferences Akperov, M., Rinke, A., Mokhov, I.
