Marine Chemistry and Biogeochemistry
Marine Chemistry & Biogeochemistry deals with the effects of the cycles of chemical elements and molecules in the seawater and ocean on the marine ecosystem and living organisms. The elements have crucial roles in vital biogeochemical and climatic processes in oceans in the past, present, and future.
We are studying marine biogeochemistry of bioessential and toxic elements such as iron, and mercury, respectively, and other trace elements in various seas, including Antarctic and Arctic waters, Norwegian and Chilean Fjords, and the Mediterranean Sea.
Following the journey of CARBON in the ocean is one of our main focuses to understanding the fundamental climatic process in which carbon main actor.
We are exploring the processes in which carbon participates, including inorganic carbon (as CO2) uptake by photosynthesis in the surface waters to their long-term storage as organic carbon in the deep waters and sediment at the sea bottom. In between, we are following the transformation of organic carbon from easily decomposable forms to refractory forms, and its transformation from organic carbon to inorganic carbon forms, such as HCO3 and CO2.
