11. Mineral dissolution from molecular to field scale
Sammanfattning : Mineral reactivity contributes to the global biogeochemical cycling of elements. CO2is consumed during the chemical weathering of many silicates and during formation of carbonates in the oceans. LÄS MER
12. Hydrological processes in firn on Storglaciären, Sweden
Sammanfattning : Understanding hydrological processes in temperate glaciers is important for both scientific and practical issues. Modelling glacier response to climatic change and the use of water from glaciers for electric power generation are some topics that require detailed information on water storage and drainage in glaciers.

13. Integration of remote sensing and ancillary data for geographical analysis and risk assessment of forest regeneration failures
Sammanfattning : The spatial distribution and size of forest regeneration areas are the basis for an analysis of where climatically unfavourable sites for forest regeneration are likely to occur if the area is clear felled. Knowledge about thermal variations is of interest in forestry, as avoidance of surface temperature extremes is important to regeneration success. LÄS MER
14. The role of sediments in the biogeochemical cycles of nutrients in the Gulf of Riga
Sammanfattning : The sediment biogeochemistry of C, N, P and biologic silica (BSi) plays an important role in cycling of these elements in aquatic ecosystems. In shallow coastal and estuarine systems, water-sediment nutrient dynamics can influence biological processes (e.g., primary production) in overlying waters. LÄS MER
15. Fate of organic carbon in a tropical mangrove ecosystem
Sammanfattning : The aim of this thesis was to study the budget and fluxes of organic carbon in a tropical mangrove forest. Maruhubi forest is located in the Island of Zanzibar, East Africa. Aspects of structure and functions of the ecosystem are investigated. LÄS MER
