16. Predictions Within and Across Aquatic Systems using Statistical Methods and Models
Sammanfattning : Aquatic ecosystems are an essential source for life and, in many regions, are exploited to a degree which deteriorates their ecological status. Today, more than 50 % of the European lakes suffer from an ecological status which is unsatisfactory. LÄS MER
17. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change
Sammanfattning : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. LÄS MER
18. Geodetic analysis for the Very Long Baseline Interferometry Global Observing System
Sammanfattning : Very Long Baseline Interferometry (VLBI) is an essential technique forspace-geodesy. It realizes the International Celestial Reference Frame(ICRF) and provides a link between the Earth- and space-fixed coordinatesystems by directly observing all Earth Orientation Parameters (EOP)simultaneously.

19. Peatland dynamics in response to past and potential future climate change : A regional modelling approach
Sammanfattning : The majority of the northern peatlands developed during the Holocene as a result of a positive mass balance between net primary productivity (NPP) and heterotrophic decomposition rates. Over that time they have sequestered a huge amount of carbon in terrestrial ecosystems. LÄS MER
20. Observations of Artificial Radio Sources within the Framework of Geodetic Very Long Baseline Interferometry
Sammanfattning : Very long baseline interferometry (VLBI) is a mature and fascinating technique with unique and indisputable applications in radio astronomy, planetary sciences, and space geodesy. The latter discipline is a field of science facilitating our understanding of various global-scale phenomena connected to Earth dynamics. LÄS MER
