PhD Researcher Sea Spray Aerosols – Deadline 01 September 2022

VLIZ aims to increase our understanding of processes and interactions in changing marine and coastal environments. It has a multidisciplinary team of passionate researchers, moving the boundaries of scientific knowledge and addressing societal challenges through excellent marine research.

We are hiring a marine researcher to start a PhD on the influence of microbial life (phytoplankton, bacteria, viruses) on the formation and stability of sea foam, which is the predominant source of sea spray aerosols. Sea spray aerosols are microscopic droplets of seawater that are formed by bubble bursting at the ocean surface. They play a major role in cloud formation and are suspected to affect human health after inhalation. Until now, research at VLIZ and Ghent University has focused on the presence and human health effects of biogenic chemicals inside sea spray aerosols. We found that the enrichment of marine biogenic chemicals inside sea spray aerosols shows strong intervariability, which we believe is caused by differences in foam stability. With this PhD, we want to get a better understanding of sea foam formation and its role in the aerosolization of waterborne chemicals and bacteria. In particular, we want to investigate whether the production of transparent exopolymer particles by bacteria and phytoplankton – released naturally or via viral lysis of these hosts – can be used to predict the abundance of sea spray aerosols and the enrichment of biogenics within them. The research will integrate field work – mainly beach sampling – with experimental approaches in the lab, combining biological observations (flow cytometry; plankton imaging) with analytical chemistry. You will be working in Ostend at VLIZ as part of a research unit devoted to various aspects of marine microbial ecology. The PhD will be performed in collaboration with the Blue Growth Research Lab of Ghent University, where another team of PhD students is working on various research projects related to sea spray aerosols.
