SUMMARY:Freshwater Colloquium – Pollution History of Black Carbon (Soot)\, Toxic Metals and PFAS in Green Bay Over the Past Century
DESCRIPTION:Green Bay\, the world’s largest freshwater estuary\, and Milwaukee Harbor have experienced significant ecological and environmental changes\, driven by increased anthropogenic activities and the introduction of invasive species. Designated by EPA as Areas of Concern (AOCs) in the 1980s\, both systems provide natural laboratories for assessing long-term pollution trends. This presentation will explore case studies on the depositional history of black carbon (soot)\, toxic metals (Cu\, Pb\, Zn\, Cd\, Hg\, Co\, Ni\, Cr\, and As)\, and polyfluoroalkyl substances (PFAS) in Green Bay sediments over the past 50-100 years\, with comparative insights from Milwaukee Harbor. \nDr. Guo’s major research focus is on aquatic biogeochemistry\, with an emphasis on the role of natural organic matter in governing the reactivity\, fate and transport of chemical species\, including trace metals\, radionuclides\, nanoparticles\, microplastics\, PFAS\, and other contaminants. He received his Ph.D. degree in Chemical Oceanography from Texas A&M University\, College Station. After working as a postdoc and assistant research scientist at Texas A&M-Galveston\, Dr. Guo joined University of Alaska Fairbanks in 2000 as a research professor in the International Arctic Research Center and then University of Southern Mississippi in 2005 as a faculty member in the Department of Marine Science. Dr. Guo has been a professor in the School of Freshwater Sciences at the University of Wisconsin-Milwaukee since 2012. Dr. Guo has authored/coauthored over 240 peer-reviewed publications\, with an H-index of 70 and over 17\,000 citations based on Google Scholar. His research influence is specifically recognized by ScholarGPS®\, which ranked him #4 globally in Dissolved Organic Carbon and #5 in Organic Matter based on publications from the prior five years (2022). He received the 2023 51���� Senior Faculty Research Award. \nSam earned her B.S. in Geography with a minor in Chemistry from UW-Whitewater in 2024. She just started the second year of her master’s here at SFS working in Dr. Guo’s lab. Her research consists of studying the historical distribution of heavy metals in Milwaukee Harbor and Green Bay sediments\, analyzing the degradation of microplastics and microplastic-derived DOM\, as well as examining PFAS molecular weight distribution via ultrafiltration. This year\, she has had the opportunity to present her research at numerous conferences\, including the Society for Freshwater Sciences annual meeting in San Juan\, PR\, the ACS Great Lakes regional meeting in Appleton\, WI\, and at the International Association for Great Lakes Research in Milwaukee\, WI. \n

SUMMARY:Freshwater Colloquium – Troubled Waters: Impacts of Emerging Contaminants on Early Life Stages of Fish
DESCRIPTION:Historically\, ecotoxicological toxicity studies were conducted with limited connections to human health. The field of environmental toxicology has recently embraced a “one health” approach\, with increased focus on understanding the underlying mechanistic effects to improve species extrapolation. While many are shifting towards in silico and Adverse Outcome Pathway approaches\, in vivo toxicity testing using zebrafish and fathead minnow larvae allows for integrated systematic toxicity screening using physiologically complex endpoints and incorporation of latent and transgenerational effects following early exposure to environmental contaminants. Dr. King-Heiden will share the approach she has used to integrate experimental endpoints useful for predicting latent and long-term risks for adverse health effects in both wildlife and humans\, focusing on her most recent studies using neonicotinoid pesticides and PFAS.  \nDr. King-Heiden is a Professor of Biology and River Studies Center at UW-La Crosse\, who specializes in the field of aquatic toxicology\, developmental biology\, and reproductive physiology. She earned her PhD from UW-Milwaukee Department of Biology\, working with Dr. Carvan at the now School of Freshwater Sciences\, studying the reproductive toxicity of Dioxin. She continued this work as a postdoc at the Molecular and Environmental Toxicity Center at UW Madison\, exploring the latent and transgenerational reproductive toxicity of dioxin\, and developmental toxicity of nanomaterials. She has been in the Biology department at UW-La Crosse since 2008. At this comprehensive university\, she is focused on teaching. Her research revolves around undergraduate and MS students\, with a continued focus discerning the impacts of embryonic exposure to emerging contaminants of concern\, using primarily zebrafish and fathead minnows as a model. Her work reveals how exposure to these contaminants influence physiological and behavioral endpoints of ecological importance\, with implications for ecological resilience as well as human health. This presentation is open to students\, faculty\, staff\, alumni and the public.

SUMMARY:Freshwater Colloquium – Changing Global Water Tables Over The Past 21\,000 Years
DESCRIPTION:Although groundwater and lakes are vital freshwater reservoirs\, little is known about how their storage volumes or regional distributions change in the long term. In this talk\, I will share results from a global-scale transient simulation of the global water table over the past 21\,000 years\, including both groundwater and lake surfaces. The simulation is obtained using the Water Table Model (WTM)\, forced by climate simulation data and topography that changes through time as a result of glacial isostatic adjustment (GIA). Our results highlight the strong correlation between precipitation and water table depth\, and the impact of melting ice sheets on lake storage. We will discuss the impacts of changing groundwater storage on global sea level\, and will also examine the impacts of lakes and groundwater on GIA.  \nKerry Callaghan is an Assistant Professor at the University of Illinois Chicago. She obtained her PhD from the University of Minnesota\, where she developed the Water Table Model (WTM)\, and then completed a postdoc at the Lamont-Doherty Earth Observatory\, Columbia University\, before starting her current position. Prof. Callaghan’s research focuses on the interactions between water and our changing landscape and Earth system.  \nThis presentation is open to students\, faculty\, staff\, alumni and the public.
