Arctic Modeling & Technology (Paty Matrai)

Video Shot in: 2022

Dr. Paty Matrai discusses her modeling work in the Arctic, focusing on autotrophic and heterotrophic processes. Initially, many Earth models underestimated the activity of the polar regions, especially during the winter. Dr. Matrai collected data to validate Arctic-specific models. Her research examines the transition zone between the North Atlantic and the Arctic, studying the movement of warm waters, productivity, and fish migration. Incorporating ocean biology and chemistry into models remains a challenge, particularly in the complex coastal regions affected by thawing permafrost. Remotely sensed data is limited due to ice and cloud cover, necessitating technological advancements on the ice and in the water itself for accurate data collection. The need for battery-powered devices hinders some research, but efforts like MOSAiC showed promise for conducting year-round work. (The goal of the MOSAiC expedition, 389 days on one Arctic expedition, was to take the closest look ever at the Arctic as the epicenter of global warming and to gain fundamental insights that are key to better understand global climate change. Hundreds of researchers from 20 countries were involved in this exceptional endeavour.)
