I did my master’s in Climate Physics. Currently, I implement data assimilation into the ocean physics and biogeochemistry model FESOM-REcoM, working also in the AWI’s Data Assimilation group. I’m interested in using data assimilation to study the global air-sea flux of CO₂.

I studied meteorology and I am interested in Earth System Models (ESMs) with a focus on ocean dynamics and their influence on biogeochemical processes. Currently, I investigate the interannual variability of the ocean CO2 sink in our warming world. I want to improve Earth System Models and enhance our understanding of climate feedbacks we will face in the near future.

I studied civil and computational mechanics in Ankara and Munich. In the past, I investigated the circulation dynamics of the Turkish Straits System and ice shelf-ocean interactions in the Southern Ocean. Currently I am developing the coupled marine biogeochemistry model FESOM-REcoM, which is also part of AWI’s Earth System Model (AWI-ESM). I also contribute to the Global Carbon Budget.

I am a PhD student studying the effect of temperature on phytoplankton growth and incorporating it into biogeochemical models and investigating the difference between phytoplankton functional groups vis à vis temperature-growth relationships.

I studied marine sciences and have worked with global ocean biogeochemistry models as well as observations in the past. I am interested in understanding ocean carbon cycling and its interactions with climate change and variability - from biological to physical processes and from preindustrial times into the future. Thus, in my group, we are working to improve process representation in the biogeochemistry and ecosystem model REcoM and simulate the recent and future evolution of the ocean carbon cycle. I also coordinate the ocean carbon sink estimate for the Global Carbon Budget.

I have a background in meteorology and have increasingly focused on studying the climate system and the carbon cycle in the ocean through various internships and projects. I completed a master's thesis on the effects of eddies on the phytoplankton bloom in the North Atlantic using a simple NPZD (Nutrient-Phytoplankton-Zooplankton-Detritus) model (biogeochemical model). I am currently pursuing a PhD on the impacts of Antarctic meltwater on the circulation of the Southern Ocean and the global carbon cycle, utilizing the AWI Earth System Model and the ocean biogeochemistry model FESOM-REcoM as part of the international SOFIA initiative.

After my studies in physics and chemistry, I did a master's degree in physical and biogeochemical oceanography on carbon fluxes in the Southern Ocean. Now I am working on a new dataset on evaluation metrics for the carbon fluxes between mixed surface layer and deep ocean based on BGC-Argo floats to evaluate the FESOM-REcoM model and improve its estimation of the ocean carbon sink.

I have a bachelor with Physics major and a master degree in Atmospheric Sciences. For my master thesis I examined the decadal variability of the carbon cycle in the Indian Ocean region. For the Ph.D. I am doing Ocean Biogeochemical Modeling for Ocean Alkalinity Enhancement in deep and bottom water formation regions. I study the efficiency of carbon dioxide sequestration in the ocean and the side effects of Alkalinity Enhancement on the ocean ecosystem.

My research focuses on understanding the global oceanic carbon cycle and associated biogeochemical interactions at different time scales. My past work includes carbon observing system simulation experiments (OSSEs) in the Indian Ocean, the role of plasticity of nutrient uptake in phytoplankton for future net primary production, and time of emergence of anthropogenically induced trends in dissolved organic matter in Earth system model simulations.

I am currently developing a benchmarking scheme for ocean carbon cycle models to assess model performance and uncertainties in estimating global ocean carbon uptake to contribute to the global carbon budget.

I monitor physical changes in the Arctic environment (Ocean currents,  water masses, mesoscale features, mixing, sea ice…) and study their impacts on phytoplankton dynamics (biomass, primary productivity, phenology, spatial distribution, composition, trends …) and biogeochemical cycles (carbon and nutrients). I used a collection of tools from in situ data (autonomous or traditional platforms) to remote sensing (ocean color, altimetry, infrared). But I am currently focusing more on BGC modelling in the framework of the H2020-Project COMFORT and the BMBF nuArctic projects. nuArctic investigates nutrient remineralization combining modelling experiments with observations from the MOSAiC expedition.

With a Master’s degree in marine biology and several field trips to the Arctic, I entered the field of biogeochemical modelling at the start of my PhD project. Therein I investigated CO2 dependencies of and multiple stressor effects on phytoplankton growth rates in published laboratory data, and developed model functions to represent these effects in REcoM. In my current work I aim to further improve the description of biological processes in REcoM for a better representation of the biological carbon pump. This work is supported by a regular scientific exchange with the phytoplankton ecophysiologists of the section. Furthermore, I’m part of the EU Horizon 2020 project OceanNETs, investigating the efficiency of ocean-based negative emission technologies in AWI’s Earth System Model AWI-ESM.

Being a physicist by training, I switched to modelling marine biogeochemistry after my PhD. My main interests are feedbacks between climate and the biogeochemistry of the ocean. The main focus in my own modelling work is on the cycling of iron in the ocean and on a better representation of phytoplankton photophysiology. I do some teaching at the University in Bremen with a focus on the carbon cycle and how the ocean circulation works.

I studied limnology and microbiology and switched to marine biogeochemical modelling with my PhD. My main interest is the feedback between climate and the marine carbon pump, particularly during paleoclimate periods. Beyond this, I also work with Dr. Christoph Völker together on process-understanding of the marine iron cycle and its impact on carbon export in the past and future.
