Overview PNNL's Earth System Science Division enables energy independence and national security through leadership in earth systems science,engineering, and decision analytics. Our work focuses on solving complex problems in the dynamic Earth system. Our interdisciplinaryscientistssteward a breadth of efforts that encompass research on plants to groundwater science and coastal zones, to storm prediction. Our research focuses on understanding and mitigating operational risks at the interface of human and natural environments. This includespredicting the impacts of natural hazards and extreme climate events on Earth and human systems, along with the impacts of wildfire,flooding, sealevel rise and storm surges. We focus on understanding and mitigating environmental contamination and increasing theresiliency, security and sustainability of water resources. We provide geointelligence through advanced sensing and data analytics toforecast complex systembehaviors and operational performance to understand human-natural systems. This includes informed decisionmaking and enhanced community resilience, advanced monitoring, and remote sensing of environmental systems for energy and nationalsecurity. It also includes developingenergy systems, including geothermal energy, sustainable oil and gas production, storage andutilization, along with carbon sequestration. Driven by a “science-to-solutions” philosophy, we provide scientific leadership and technology to enhance national security, mitigate naturalhazards and optimize disaster response. In the critical areas of energy, environment, intelligence, and defense, we deliver insights anddecisionsupport through the development of tools and solutions. Responsibilities Contribute to PNNL’s goals as part of the Lab’s Energy and Environment Division (EED). With support from DOE-RL (Richland), we develop and implement long-range remediation strategies, in coordination with inputs from the Hanford Site Contractor, providing the essential scientific, technical and engineering basis for implementing DOE's
