Chasing Polar Microbes

PhD student Maria Lund Paulsen tells the story of being a marine microbiologist in the fascinating Arctic environment. Below the surface of the sea, invisible microorganisms are strugling for their existence; a fight between microalgae who consume CO2 and bacteria how produce CO2. Maria and her collegues investigate how the balance between these two is changing under a changing climate. She is particularly interested in consequences of thawing permafrost and meling glaciers. The microbial world below the sea surface makes up 50% of the marine food web production and is of strong significance for the climate.
