SIMÓ LAB Postdoctoral research position: volatiles in the ocean a l'Institut de Ciències del Mar

Planktonic microorganisms in the ocean produce and release volatile organic compounds (VOCs) as by-products of their metabolic and feeding activities. In marine ecosystems, VOCs have evolved functions that include alleviation of oxidative stress, chemical communication, and climate regulation. We aim at deciphering the chemical, eco-physiological and environmental factors driving their production and cycling, and their temporal and spatial scales of variability. The ultimate goal is to get necessary information for diagnosing and simulating their distribution in the surface ocean and exchange with the atmosphere.

The postdoc researcher will be in charge of our Vocus (Tofwerk) PTR-ToF-MS to measure VOCs in marine air and seawater. Focus will be placed on biogenic VOCs whose concentrations are regulated by biological and photochemical processes, with a special focus on sulfur containing compounds.  A  custom-made  Segmented  Flow  Coil  Equilibrator  (SFCE;  Wohl  et  al.  2019)  is currently installed in our research lab and will be used to measure dissolved VOCs from seawater. Production and consumption processes will be investigated using stable isotope- labeled VOCs.

For experimental lab work, the researcher will have access to cultures of bacteria, phytoplankton and herbivore protists, a sunlight simulator, and fully equipped biological and gas chromatography labs. Field work will include oceanographic expeditions to the Mediterranean, North Atlantic, and polar environments.
