Today we take a break from discussing the latest Great Lakes research to recognize one of the scientists who laid the foundation for modern water science. 

From the U.S. Geological Survey’s Science Features:  

Luna B. Leopold, son of famed conservationist Aldo Leopold, arrived at the USGS in 1950. For the next two decades, Leopold revolutionized hydrologic sciences within and outside the USGS. He is best known for his work in the field of geomorphology, the study of land features and the processes that create and change them. His work is often cited today by leading scientists in water research, both at the USGS and around the world. 

Leopold had a lasting impact on the field of water science. He knew the broader importance of our water resources and that humans can have great impact on whether water is available, now and in the future. Our society depends on safe and reliable water supplies, as do the Earth’s diverse and valuable ecosystems. Today, our nation is faced with the challenge of balancing a finite freshwater supply between competing needs, such as agriculture, drinking water, energy production, and ecosystems. 

Leopold recognized the fundamental value of science in making smart decisions about water resources and laid the groundwork for modern water science. During his tenure he transformed USGS water research into a professionally-recognized provider of water quality and availability information.

For six years, he served as a hydraulic engineer before becoming the first Chief Hydrologist in the history of the USGS, a position he held until 1966 when he stepped down to pursue his research. While at the USGS, he led the effort to restructure the water science programs to focus on viewing water as a single resource. For example, USGS continues to research the interactions between surface water and groundwater, because use of either of these resources affects the quantity and quality of the other.

We are excited to offer the opportunity to propose a speaker or panel session during the 2026 Emerging Contaminants in the Environment Conference April 28-29.  The conference will feature traditional 15-minute presentations and a poster session on the latest in emerging contaminant research, policies, and outreach in the soil, water, and air.The deadline to propose a session is June 16, 2025.Learn more at the link in bio.
A recent @seagrant_noaa publication, Aquaculture Regulation in the Great Lakes, serves as a valuable resource for fish farmers & policymakers in the region in navigating the complex legal environment of aquaculture.The report breaks down complex legal framework and provides practical insights to help aquaculture producers understand and navigate state and regional requirements with greater confidence.It was developed by the National Sea Grant Law Center in partnership with @mnseagrant-led Great Lakes Aquaculture Collaborative (GLAC) which formed to support aquaculture in the eight Sea Grant programs that border the Great Lakes and Lake Champlain. Read more and access the report at the link in bio.
Our new aquaponics curriculum is here! Designed for 9-12th grade classrooms with operating aquaponics systems, this curriculum, created by educators for educators, teaches STEM concepts through the lens of aquaponics, aligning with NGSS and Great Lakes Literacy Principles.

Congress is finalizing the FY26 budget, and federal funding for Sea Grant programs across the country—including Illinois-Indiana Sea Grant—is uncertain. Sea Grant programs have consistently had broad community and political support, and now such support is more important than ever.Add your name to our sign-on letter urging Congress to support continuation of programs benefiting the Great Lakes, supporting local economies, and connecting communities with science-backed solutions.Scan the QR code or visit the link in bio to take action.
