Penn State Researchers Use Deep Learning to Study Oxygen Levels in U.S. Rivers
Understanding the amount of dissolved oxygen in rivers is crucial for the survival of aquatic life. Researchers at Penn State have used a deep learning model to analyze data from hundreds of rivers across the United States to determine which factors most affect oxygen levels. According to Wei Zhi, assistant research professor, and Li Li, Barry and Shirley Isett Professor, the study found that temperature is the most significant factor influencing dissolved oxygen, followed by sunlight, with stream flow having minimal impact.
Importance of Dissolved Oxygen
Dissolved oxygen is vital for fish and other aquatic organisms. The study, published in Nature Water, highlights the importance of understanding how temperature, light, and flow affect oxygen levels. Traditionally, predicting these levels on a large scale was challenging, but deep learning models now allow for systematic analysis.
Research Findings
The research used 40 years of data from 580 rivers, revealing that temperature is the predominant driver of daily dissolved oxygen dynamics. This has significant implications for water security and ecosystem health as rivers warm in the future.
Support and Contributions
This project was supported by the Barry and Shirley Isett professorship and the U.S. Department of Energy. Contributions also came from Chaopeng Shen and Wenyu Ouyang.
