The research group in environmental geochemistry is focused on sulfur and metal geochemistry as well as nutrient cycling in Boreal coastal, lacustrine and marine landscapes. Research includes: (1) nutrient cycling in lake ecosystems and restrain of the internal and external loading, (2) identification methods and management of acid sulfate soils and assessment of the fate of associated metal species along the biogeochemical spatial gradients from the coastal terrestrial environment to the Baltic Sea, and (3) biogeochemistry of marine sediments with emphasis on the long-term environmental changes caused by climatic oscillations and anthropogenic nutrient loading.
Ph.D. Peter Österholm (ÅAU)
Environmental geochemistry with focus on the effects of watershed land use on soil geochemistry and recipient streams and estuaries.
Ph.D. Eila Hietaharju (UTU)
My responsibilities are mostly teaching (quaternary geology, hydrogeology and geochemistry), study counselling, personal study plans. My research interests and fields of speciality are on paleolimnology and geochemistry; especially eutrophication and nutrient cycling.
Ph.D. Miriam Nystrand (ÅAU)
Element concentration, fractionation and/or speciation in natural waters, peat and sediments mostly influenced by acid sulfate soils.
Heider AL Humadi (UTU)
My project focuses on the isotope geology and geochemistry of the felsic, mafic and ultramafic rocks from the supra-subduction zone Mawat ophiolite, NE Iraq.
M.Sc. Sami Jokinen (UTU)
I am probing the long-term development of hypoxia in the coastal zone of the northern Baltic Sea using various geochemical and sedimentological methods.
M.Sc. Stefan Mattbäck (ÅAU)
Acid sulfate soil analysis, characterization and mapping
M.Sc. Miradije Rama (ÅAU)
Studying area is environmental geology. Focused on using smart clay mineral to recycle nutrients from wastewater. Recycling of nutrient is a “key of our future”.
