Introduction
I am a PhD researcher in the Environmental Geochemistry Group lead by Tom Jilbert, at the University of Helsinki. In my PhD project, I study the use of redox-sensitive trace metals (TM) in coastal marine sediments as indicators for coastal deoxygenation. Specifically, I investigate to what extent other factors than oxygen control TM enrichments in those sediments. The project is funded by the Research Council of Finland and Onni Talas Foundation.

Fjord systems are typically affected by low‐oxygen conditions, which are increasing in extent and severity, forced by ongoing global changes. Fjord sedimentary records can provide high temporal resolution archives to aid our understanding of the underlying mechanisms and impacts of current deoxygenation. However, such archives can only be interpret...
Sedimentary molybdenum (Mo) and uranium (U) enrichments are often used as redox proxies to reconstruct bottom water redox changes. However, these redox proxies may not be equally reliable across a range of coastal settings due to varying depositional environments. Fjords vary greatly in their depositional conditions, due to their unique bathymetry...
Sedimentary molybdenum (Mo) and uranium (U) enrichments are widely used to reconstruct changes in bottom water oxygen conditions in aquatic environments. Until now, most studies using Mo and U have focused on restricted suboxic-euxinic basins and continental margin oxygen minimum zones (OMZs), leaving mildly reducing and oxic (but eutrophic) coasta...
Increasing occurrences of extreme weather events, such as
the 2018 drought over northern Europe, are a concerning issue under global
climate change. High-resolution archives of natural hydroclimate proxies,
such as rapidly accumulating sediments containing biogenic carbonates, offer
the potential to investigate the frequency and mechanisms of such...

An extensive data set of biogenic silica (BSi) fluxes is presented for the Peruvian oxygen minimum zone (OMZ) at 11°S and 12°S. Each transect extends from the shelf to the upper slope (∼1,000 m) and dissects the permanently anoxic waters between ∼200 and 500 m water depth. BSi burial (2,100 mmol m⁻² yr⁻¹) and recycling fluxes (3,300 mmol m⁻² yr⁻¹)...
