    People Want Parks: Results from a Lincoln Park Climate Resilience Survey
    (2023-03) Sowers, Maia A; Rodman, Madison G; Sprague, Tiffany A; Bliss, Morgan
    One Block at a Time Survey Overview Poster, 2023. This poster presents preliminary results from a survey conducted as part of the One Block at a Time project. We conducted a community survey of 100 residents from the Lincoln Park neighborhood in Duluth, Minnesota to understand the climate and water challenges they face, the types of urban green spaces they valued, and what types of green spaces they would like to see in their community. Preliminary results show that 74% of respondents felt it was important to reduce community water damage and 55% were concerned about changes to future water quality. The three most important urban green spaces to residents were parks, bodies of water and trails. This work was one part of the multi-phase One Block project which also included a background assessment of community and climate vulnerabilities for the neighborhood; visioning sessions with community leadership team; and implementation of education and outreach and small-scale green infrastructure projects within the neighborhood during the fall of 2023.

    Advanced water quality monitoring of optically variable lake systems using Landsat 8 OLI and Sentinel 2 MSI imagery in an automated high-performance computing environment
    (2023) Olmanson, Leif; Porter, David
    In lake-rich regions, like Minnesota USA, protecting water quality is critically important because of the ecological and economic importance of recreational activities and tourism. To ensure the health of inland aquatic ecosystems on both a local and regional scale, more comprehensive monitoring techniques to complement conventional field sampling methodologies are needed for effective management. For over 25 years, we have used Landsat imagery for water clarity measurements on 10,000+ lakes at five-year intervals but with recent advancements in spatial, spectral, radiometric, and temporal resolution of satellite imagery we can measure more water quality variables more often.

    Aquatic invasive species prevention: getting the best bang for the buck!
    (2023) Angell, Nichole; Bajzc, Alex; Brady, Valerie; Campbell, Tim; Doll, Adam; Dumke, Josh; Kinsley, Amy; Keller, Reuben; Phelps, Nicole
    Common AIS prevention efforts focus on public education, watercraft inspection, and watercraft decontamination. While these prevention efforts are currently widely implemented, little is understood about the cost-effectiveness of these methods.

    R/V Blue Heron The University of Minnesota’s Research Vessel
    (2023) Ricketts, Doug; Lee, Rual
    The Large Lakes Observatory operates the largest university owned research vessel in the Great Lakes, R/V Blue Heron. Built in 1985 for fishing on the Grand Banks, the Blue Heron was purchased by the University of Minnesota in 1997, sailed from Portland, Maine, up the St. Lawrence Seaway to Duluth, and converted into a limnological research vessel during the winter of 1997-98. The Blue Heron has berthing for 11 crew and scientists, and can operate 24 hours per day for up to 21 days in between port calls. The Blue Heron is part of the University National Oceanographic Laboratory System (UNOLS ), and is available for research scientists on any of the Great Lakes.

    Peat Derived Anion Exchange Materials for Sulfate Remediation in Mine Pit Water
    (2023) Yemets, Sergiy; Kolomitsyn, Igor
    A number of new natural peat derived anion exchange materials were developed in our laboratory. A batch testing of these new anion exchange materials were conducted. Recently we have demonstrated that peat derived anion exchange materials have strong binding affinity to per- and polyfluoroalkyl substances (PFAS). The initial positive results prompted us to investigate their efficiency to remove sulfate anions from mine pit water. Isotherms for chloride to sulfate exchange in a selected material fit Langmuir and Freundlich adsorption models. The practical limiting retention capacity was found to be 108 mg/g for the material (SY2205165) and 167 mg/g for the commercial anion exchange resin (Resinex). The new materials demonstrate their potential for the sulfate removal from the contaminated water sources. Further experiments on evaluation of selected peat lignin derived anion exchange material as well as sulfate selective commercial anion exchange resin in the column environment will be performed for the practical implementation.
