Dr. Ryan Pereira, Heriot-Watt University, Edinburgh/Scotland, UK:
"Through the Looking-Glass (at Dissolved Organic Matter), and What We Found There"
Abstract:
From the chapters of "Garden of Live Flowers" to "it's my own Invention" it seems as though the exploration of Earth's myriad pools of organic matter by the Carbon-Water Dynamics Research Group (Carbon-Water Dynamics) and Alice's adventure in Wonderland may have some similarities. In this presentation, I will present work that challenges traditional views on carbon and nutrient transport along the land-ocean-atmosphere continuum. In this presentation, we will take a closer look at interfaces where dissolved organic matter acts as an important intermediate in regulating climate feedbacks between the water and atmosphere.
