The project "Solving the Puzzle of Organic Matter in the Ocean," focuses on developing new chemical approaches to understand the marine carbon cycle. This research is significant due to the complexity and importance of dissolved organic matter (DOM) in the ocean. DOM represents a substantial portion of the ocean's organic carbon, yet its composition and role in the carbon cycle are not well understood. The research team is employing statistical methods to analyze complex chemical data sets, aiming to trace the origins of DOM, how it has interacted with marine ecosystems in the past, and predict its future pathways.
By dissecting the chemical nature of DOM, the project seeks to improve monitoring methods for marine ecosystems and enhance understanding of the ocean's role in the global carbon cycle. The work spans from coastal systems to the open ocean, exploring how different fractions of DOM function within the marine ecosystem. Some fractions serve as food sources for microbes, while others act as long-term carbon storage. This work is crucial for understanding environmental shifts in marine ecosystems and contributes to a more comprehensive grasp of the oceans' role in our world.
