During his PhD studies Lasse Z. Jensen explored the seasonal origins of Arctic atmospheric particles and their impact on climate dynamics. Jensen investigated various Arctic environments, ranging from soil and streams to seawater and sea ice. Through his research, he uncovered the seasonal patterns of ice nucleating particles (INPs) and the microbial community composition, including bacteria, fungi, and microalgae. His findings illuminate the link between these particles and microbial communities across the cryosphere, crucial for cloud formation and Arctic climate regulation. These new research findings deepen our understanding of Arctic ecosystems and underscores the pressing need to address their impact on cloud dynamics and climate change.

The PhD study was completed at Department of Biology, Faculty of Natural Sciences, Aarhus University.
