My research concentrates on measuring the amount of carbon dioxide (CO2) and methane (CH4) that the coastal ecosystem exchanges with the atmosphere. My main method of research is the eddy covariance technique, which provides near-continuous measurements of these gas fluxes. In addition, we test and develop existing models in order to quantify how physical drivers in the natural environment, such as wind and the heating and cooling of water, control the exchange of gases.
Keywords: greenhouse gas fluxes, eddy covariance, sea–atmosphere interaction, turbulence, carbon cycling
I am interested in causes and consequences of biodiversity change in plankton food webs and I’m passionate about its complexity.
My research is focused on species interactions within phytoplankton to understand how changes in diversity alter resource use efficiency and primary productivity in the sea. From the food web perspective, I examine how producer and consumer diversity affect elements cycling and energy transfer between trophic levels. I like to combine different approaches to understand plankton dynamics, including field and laboratory experiments, data analyses and statistical models. Within CoastClim I study the consequences of plankton biodiversity change for pelagic carbon uptake.

I study how chemical emissions from the sea surface can react in the atmosphere and form new aerosol particles, which are important for the Earth’s radiative balance and climate. In my PhD, I studied these phenomena in coastal and open ocean environments in New Zealand and I am looking forward to discovering how different the Baltic Sea is.

I am a marine biogeochemist/aerosol physicist and a theme throughout my research career has been the interaction between the surface ocean and the atmosphere. More specifically, I am interested in the emission of matter from the oceans, in the form of sea spray aerosols (SSA), and how these aerosols can impact climate and transport pollutants.
Within the CoastClim project I am responsible for establishing the air-sea interaction laboratory at the Askö laboratory. This facility will build upon my expertise in the laboratory generation of SSA using state-of-the-art simulation chambers with a view to investigating the links between marine biodiversity, biogeochemistry and SSA production and properties within the Baltic Sea.

Volatile organic compounds are constantly emitted to the atmosphere from different ecosystems as well as anthropogenic processes. I study how these compounds oxidize in the atmosphere, with a particular focus on processes forming oxidation products of very low volatility, as these can contribute to particulate matter. These aerosol particles are important as they impact Earth’s radiation balance.

My research interest lies into understanding and quantifying the role of coastal marine environment as sink or source of greenhouse gases (GHG, i.e., CO2, CH4, N2O) to the atmosphere. Gas dynamic is investigated, in association with the highly heterogeneous coastal ecosystem, to determine the scale and drivers of changes in GHG concentrations. What are the key contributors to GHG exchanges with the atmosphere? How will those exchanges evolve in the future?

My research focuses on the role of emissions (inorganic and organic) from coastal and marine habitats in modifying the atmospheric chemistry and more particularly their impact on new particle formation (NPF), cloud condensation nuclei (CCN) and radiation budget in the atmosphere, integrating the role of meteorology in the entire dynamics. Currently, I am exploring the role of biogenic emissions from the Arctic coastal regions and arctic tundra on the new particle formation and eventually understanding the CCN and overall Cloud formation in Arctic could be impacted by biogenic-NPF.

My training is in marine ecotoxicology, and today as the Director of the Baltic Sea Centre, I facilitate the overall strategic partnership between Stockholm University and the University of Helsinki in the field of marine research. I have a particular interest in science communication, and I am leading the communication group at the Baltic Sea Centre that aims at conveying the right information at the right time and place to relevant decision makers. Thus, we translate important scientific CoastClim results into decision support and thereby assist management options regarding biodiversity and climate change issues in the coastal zone of the Baltic Sea.

My research focuses on biogeochemical processes in human-impacted aquatic systems, such as eutrophic coastal seas and freshwater lakes. Within CoastClim I am studying the coupled dynamics of carbon, nutrients and other elements in coastal sediments of the Baltic Sea.
Sediments are important reactors in which microbes transform elements from one form to another, controlling their eventual fate. For example, carbon can be buried in complex organic molecules that resist degradation, thus acting as a carbon sink, or converted to greenhouse gases such as carbon dioxide and methane that escape to the atmosphere. We want to understand the controls on these processes to better predict carbon and nutrient cycling in the future.
Keywords: sediments, eutrophication, deoxygenation, nutrients, carbon, diagenesis
