The Arctic Ocean and its coastal areas are especially vulnerable to climate change. Its ecosystem is rapidly changing in response to temperature increase, loss of sea ice, and the combined effects of additional stressors such as freshwater input and legacy pollutants. However, the scientific community currently lacks sufficient information on the mechanisms and drivers behind the biogeochemical cycling of these additional inputs and the consequences that may arise for the Arctic environment. In July 2020, we collected water samples from the water column of Kongsfjorden (Svalbard, Norway) and from glacier meltwater streams draining into the fjord. The aim of the ongoing study is to understand the mechanism of trace metal and carbon cycling in a polar fjord system that is influenced by meltwater from marine- and land-terminating glaciers. Therefore, filtered water samples (< 0.22 µm) were subject to multi-element analysis via ICP‑MS and measured for further parameters such as alkalinity (AT), dissolved ... : This talk was given at the Gordon Research Seminar Polar Marine Science on 4th March 2023. ...
