Dr. Papakyriakou conducts research in the area of microclimatology. In a broad sense his research examines biosphere-atmosphere linkages for different environments within Canadian Arctic coastal and coastal marine environments to tease out the complex interplay among components of the surface heat budget, the air-sea exchange of biogenic gases, including CO2 and CH4, and a host of physical, chemical and biological processes that underpin the exchange. The Arctic Ocean and its peripheral seas undergo strong seasonal change, and are often subject to regional controls. An objective of Dr. Papakyriakou's work is to understand the nature of process linkages that drive air-sea coupling across the seasonal transitions, and over a variety of important coastal environments. Research will assist in defining the role of rapidly changing Earth systems on major biogeochemical cycles with ramifications on both the atmosphere and ocean. Research is empirical and has a strong field component.
Dr. Papakyriakou has been a project lead in major networks, including
