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 August 2021, water samples were collected in 5 offshore transects along the coast of West Greenland between Nuuk and Disko Bugt. The aim of the ongoing study is to understand the mechanism of trace metal and carbon cycling in polar coastal areas that are influenced by meltwater fluxes from retreating glaciers, icebergs and sea ice. Therefore, filtered water samples (< 45 µm) were subjected to multi-element analysis via ICP-MS and measured for further parameters such as alkalinity (AT), dissolved inorganic carbon ... : This poster was shown at the Gordon Research Conference Polar Marine Science from 5 - 10 March 2023. ...
