Our multi-national team spans across four institutions and various career stages with expertise in biogeochemistry, physical oceanography, ocean robotics, microbiology, and numerical modelling. Further, there are many more who we are grateful to collaborate with.
University of Gothenburg
Within RECLESS, University of Gothenburg will bridge experimental biogeochemistry and autonomous observations. We will do this through the quantification and analysis of microbial nitrogen transformation rates using advanced stable isotope techniques and field-based measurements. In parallel, we will deploy innovative autonomous gliders to resolve fine-scale spatial and temporal variability in oxygen dynamics. UGOT is also home to the R/V Skagerak, a state-of-the-art marine research platform that will enable our field campaigns in the Baltic Sea.
The University of Southern Denmark’s (SDU) main role in RECLESS is to contribute to the development of novel technologies and instrumentation. This work will primarily focus on in situ approaches utilizing high-sensitivity oxygen sensors deployed across a range of platforms, including in situ incubators and gliders. In addition to this core focus, SDU will explore and quantify dark oxygen production in natural environments.
The team at the University of Vienna contributes to RECLESS by investigating what regulates microbial physiology and activity across scales. We study them one cell at a time using high resolution mass spectrometry to quantify growth and metabolic activity of individual members within key functional groups. In parallel, we profile community composition and gene expression and relate these patterns to in situ measurements from field experiments. To establish causality, we perform controlled laboratory experiments with pure cultures to test how specific environmental factors shape microbial traits and functions.
The Global Microbial Ecology group at Carnegie Science, led by Emily Zakem, uses theoretically grounded models of microbial functional types to understand how biogeochemistry emerges dynamically from ecological interactions in modeled OMZs. For our work with RECLESS, we will integrate high-resolution ocean circulation models with models of microbial functional types that are informed by the observations and experiments from the other members of RECLESS. This will allow us to better understand the dynamic microbial response to variable oxygen supply in these anoxic ecosystems.
