Jacob Geersen	Marine Geologist
©Rövensthal	Numerical modelling of coastal and marginal seas (especially the Baltic Sea), focusing on circulation, mixing, turbulence, and saltwater intrusion. Lagrangian particle dynamics and transport processes, including pollutants, sediments, and ecological tracers. Coupling physical ocean processes with environmental impacts such as oxygen variability, sea level extremes, coastal hazards, and ecosystem dynamics, increasingly using machine-learning-based prediction methods.

Jan Henkel	Marine Biologist
	My research focuses on the adaptation of specific brackish bacterial species to fluctuating salinity levels by combining metagenomic community profiling with the isolation of key species. Through time-series analysis, I investigate how shallow-water microbial populations respond to shifting environmental conditions and extreme events, with a particular emphasis on interactions with macroorganisms (such as seagrass) and the dynamics of pathogenic bacteria.

Robert Mars	Engineer
	I investigate the biogeochemical cycling of climate-relevant trace gases such as nitrous oxide (N₂O), methane (CH₄), carbon dioxide (CO2) and carbon monoxide (CO). Within the S2B, I am particularly interested on the exchange fluxes of these gases across the sediment- water (ice)-air interfaces, and how their spatio-temporal variability sets the overall coastal radiative balance.

Ingrid Sassenhagen	Marine Biologist
	My research focuses on the quantification of greenhouse gases, particularly nitrous oxide, including its concentrations and fluxes across the sediment–water–air interfaces. I aim to achieve a quantitative understanding of how physical changes at the sediment–water interface influence nitrous oxide production.

Heide Schulz-Vogt	Marine Biologist
©Rövensthal	Applied coastal water research with a focus on assessing benefits provided by coastal ecosystems as well as impacts of human activities or measures on these ecosystems. Interested in supporting coastal and marine policy implementation by applying model results to practical research questions.
