This project will evaluate the impacts of microplastics, in combination with a common environmental estrogen (17-alpha ethinyl estradiol) on critical early life stages of a model species, the fathead minnow (Pimephales promelas). Specifically, these data will seek to fill knowledge gaps in three areas; (i) the impacts of microplastics on fish at early life stages; (ii) the potential for transgenerational and multigenerational effects of exposure; and (iii) the effects of multiple environmental stressors on individuals. 

The objective of this research is to develop and implement a new modeling framework, integrating flooding intensity data of the Southern Lake Michigan transportation network with alternative fuel vehicle routing models, for the evacuation of vulnerable communities during hazardous flooding events in a changing climate. We propose a novel evacuation routes planning framework for multiple types of vehicle fuels that have dependencies on refueling and charging infrastructure (e.g., gasoline, battery electric, and fuel cell electric vehicles). The model determines the optimal evacuation routes for each alternative vehicle fuel type that minimizes the total travel and refueling time of travelers during simulated hazardous flooding events in the Southern Lake Michigan transportation network. The designed evacuation route resources will enable decision-makers to have access to data and tools so as to plan for a diverse set of travelers with alternative fuel vehicles to evacuate and adapt during these extreme flooding events, minimizing their degree of vulnerability and sustaining resilient communities.

• To measure the economic benefits of tourism-based activities for the Grand Calumet River Waukegan Harbor Areas of Concern following cleanup and restoration.
• To identify socioeconomic benefits of community revitalization through increased jobs due to robust growth in the tourism sector.
• To test whether gentrification or preference-based sorting predominates restoration and remediation incentives in contrast to a more stable resident population.
• To engage in outreach with local stakeholders and communicate findings on economic benefits of environmental projects.

Little progress has been made toward reducing fatal drowning incidents in the United States (U.S.) in the last 20 years. Recent data from the Great Lakes indicate the COVID-19 pandemic resulted in excess drownings during summer 2020. Chicago has 26 miles of Lake Michigan shoreline and 24 free, public beaches that are punctuated with piers and jetties. The resultant structural currents pose unique risks to patrons who often access the lake outside of the official summer season and in the summer season after lifeguards go off duty at 7 p.m. There is an urgent need for effective education programs to raise awareness about recreation safety in Lake Michigan, the deadliest of the Great Lakes, and to increase water competence in diverse communities that have historically been excluded from swimming. The community-engaged injury prevention and water safety experts in Chicago are uniquely situated to respond.

Objective 1: To assess the impact of Chicago Park District’s Community Water Safety Trainings on program participant knowledge and skills, community-level knowledge, and distressed swimmer events and drownings.

Objective 2: To implement, pilot, and evaluate the Swim to Survive Program enhanced with Great Lakes safety education in Evanston, IL and adapt the program for implementation in Chicago communities.

High lake levels have reduced beach sizes across Chicago, but we have little understanding of how much was passive inundation versus sediment remobilization. Ongoing collaborative efforts with the Chicago Park District and the Illinois Coastal Management Program are focused on observations of process-landform dynamics using camera arrays at select beaches and integrating UAS-based imagery, topographic information, wave data, and camera footage. However, while efforts are underway to understand the subaerial dynamics here (e.g., shoreline behaviors), little is known about littoral dynamics and sand transport across the highly fragmented urban nearshore environment, where prior studies have inferred a complex lakefloor geology that includes outcropping Silurian bedrock reefs, heavily scoured and dissected glacial clay tills, and thin, discontinuous sand veneers. We wish to capture the geologic configuration of the nearshore at the surface and map the shallow subsurface architecture as a means of quantifying sand volumes and relating them to the broader geologic template and the urban infrastructure with its influence on nearshore hydrodynamics.

Our overall goal is to is to is to gain insight into the basic biology of Craspedacusta in order to better predict its ecological impact in response to climate change. In particular, we are interested in the following questions:

1. What are the environmental cues for Craspedacusta jellyfish blooms and can these cues predict when and where Craspedacusta blooms will occur in southern Lake Michigan?
2. Can these conditions be replicated in a laboratory environment to induce jellyfish formation?
3. Are the genetic mechanisms that control jellyfish blooms in Craspedacusta similar to that of their marine relatives, and thus likely to have a parallel response to climate change?

To address these questions we have three primary objectives:

1. Determine environmental parameters required for jellyfish blooms through field work and citizen science approaches;
2. With the involvement of undergraduates we will design and conduct laboratory experiments utilizing environmental parameters and zooplankton composition data from objective 1, with the intention of culturing Craspedacusta medusae to their reproductive stage.
3. Conduct transcriptional analyses to document differential gene expression in the different life cycle stages to determine the genetic cues for life cycle transitions. 

We have a fourth objective to improve scientific literacy on invasive aquatic species though developing educational modules with live Craspedacusta jellyfish for the public, K-12 classrooms, focusing on underserved communities.
