Linking land-sea fluxes of nutrients and sediments to micrometer-scale processes in an Arctic fjord.
Thor Markussen, PhD student, CENPERM /Department of Geosciences and Natural Resource Management
During the melting season vast amounts of inorganic and organic matter is moved from the terrestrial to the marine environments in the Arctic. The matter may contain significant amounts of nutrients thus translocated to the marine environments and ecosystems. This talk will focus on the Disko Fjord meltwater system with a specific focus on iron, which the system is particularly rich in. The iron interacts greatly with the sediment particles ultimately altering the distribution of the sediments and nutrients in the fjord system. I will show new ways we are able to understand these particle processes due to the added information acquired from an in-situ camera system and also point to issues with the system and methods that warrants further investigations. Furthermore, the talk will aim at highlighting why we need to understand the interaction between nutrients and fine-grained sediment processes on the micrometer scale in order to predict nutrient and sediment redistribution on the terrestrial-marine scale.
