1. Språket och skolämnet svenska som andraspråk : Om elevers språk och skolans språksyn
Sammanfattning : Since the school subject Swedish as a second language was established in the Swedish school system in the mid-1990s, the organization of the subject has varied widely across schools, and the outcomes have been poor. This thesis investigates these problems linguistically. LÄS MER
2. Fluxes of Sensible and Latent Heat and Carbon Dioxide in the Marine Atmospheric Boundary Layer
Sammanfattning : Oceans cover about 70% of the earth’s surface. They are the largest source of the atmospheric water vapour and act as enormous heat reservoirs. Thus in order to predict the future weather and climate it is of great importance to understand the processes governing the exchange of water vapour and heat between the ocean and atmosphere. LÄS MER
3. Mechanisms controlling air-sea gas exchange in the Baltic Sea
Sammanfattning : Carbon plays a major role in physical and biogeochemical processes in the atmosphere, the biosphere, and the ocean. CO2 and CH4 are two of the most common carbon-containing compounds in the atmosphere, also recognized as major greenhouse gases. LÄS MER
4. On mechanisms controlling air-sea gas exchange
Sammanfattning : Carbon is essential to the Earth’s system functioning, playing a major role in physical and biogeochemical processes in the atmosphere, the terrestrial biosphere, and the oceans. The concentration of carbon-based greenhouse gases in the atmosphere, such as carbon dioxide (CO2) and methane (CH4), has been increasing since the industrial era. LÄS MER
5. Air-Sea Fluxes of CO2 : Analysis Methods and Impact on Carbon Budget
Sammanfattning : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution. The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans. LÄS MER
