Project description: Coastal sediments are vulnerable ecosystems threatened by various kinds of pollution, and harbor a complex microbial community and biogeochemistry that is hardly explored. With a warming potential that is 34 times higher than CO2, methane (CH4) is a significant contributor to the global greenhouse effect. The balance between CO2 and CH4 emissions, which is steered by the microbial methane cycling community, has therefore a major impact on global warming. This warming will have stimulating effect on both methane-producing (methanogenic) and methane-consuming (methanotrophic) microorganisms. However, since different microorganisms are differentially affected by these changes, the effects on net greenhouse gas (GHG) fluxes remain elusive. Within this project you will study the in situ methanogenic and methanotrophic activity and community composition in situ. You will also study the methane cycling activity in controlled laboratory settings. Suitable samples will be used for enrichment of novel microorganisms. The data will be used as input for new global gene-based models. Sampling campaigns with NESSC partners to suitable field sites will be part of the PhD study.
