Investigation and quantification of sediment-seawater interactions.
Advancing sampling, processing and analysis techniques for trace element isotopes.
Identification of micronutrient sources and sinks in the polar ocean.
My research focuses on the marine cycle of trace metals including their isotope compositions and elemental concentrations. Understanding geochemical processes in the ocean is of great importance for modern, paleo- and future applications. E.g. tracing the modern ocean circulation and identifying the sources and sinks of trace metals allows for a deeper understanding of the connection between the global ocean and Earth’s crust as components of the climate system. Tracking the modern ocean helps reconstruct the past ocean circulation and weathering inputs, because we become able to detect the course of water masses throughout the different basins. In turn, these reconstructions provide insights in how the climate system has changed and could change in the future. Ocean geochemistry contributes to compose the big picture of how the ocean interacts with the global climate.
