Round Goby and Mottled Sculpin Spawning Interactions

Principal Investigator: John Janssen
Affiliation: University of Wisconsin-Milwaukee WATER Institute
Initiation Date: 1998
  • Determine whether round gobies interfere with mottled sculpin spawning
  • Compare spawning shelter requirements of the two species in a effort to find methods of minimizing round goby spawning success while maximizing mottled sculpin spawning success

Low Frequency Electromagnetism as an Effective Method for the Control of Zebra Mussel Infestation

Principal Investigator: Matthew Ryan
Affiliation: Purdue University Calumet
Initiation Date: 1998
  • Investigate the application of extremely low frequency (ELF) electromagnetic (EM) radiation as an effective method for the control of zebra mussel (Dreissena polymorpha)
  • Monitoring the survival of zebra mussels in water which has been irradiated by an ELF EM field via the
    efflux of the metal ions Ca2+, Mg2+, Na+ and K+ from zebra mussels exposed to the field
  • Developing quantitative mathematical models will to interpret the experimental findings

Contamination of Wetland Sediments Indiana Dunes National Lakeshore: Implications for Wetland Restoration Strategies

Principal Investigator: Catherine Souch
Affiliation: Indiana University-Purdue University Indianapolis
Initiation Date: 1998
  • To quantify the current environmental quality, both in terms of metal concentrations and ambient conditions (pH, Eh temperature. groundwater flow directions and velocities), in different subenvironments (defined in terms of hydrologic, ecological and disturbance histories) of the Great Marsh, Indiana Dunes National Lakeshore
  • To develop simple models/relationships to explain the spatial distribution of heavy metals across the Great Marsh and with depth within the sediments, and the environment conditions associated with enhanced mobility
  • To use these models/relationships to determine the potential for heavy metal release associated with certain changes in hydrology, hydrochemistry and sediment chemistry that may occur during and following wetland restoration at the Great Marsh

Natural Photochemically Mediated Destruction of Contaminants in Rivers and Lakes of the Calumet Area

Principal Investigator: Gary Peyton
Affiliation: Illinois State Water Survey
Initiation Date: 1998
  • Identify specific radicals and other reactive species that are photochemically generated in water bodies of the Calumet Watershed
  • Quantify the rates of generation of such species
  • Relate the rates of active species generation to the water composition
  • Develop a general protocol for carrying out such studies
  • Develop a predictive model for the observed phenomena
  • Identify implications and impacts of the findings

Outdoor Recreation and the NSRE: An Examination of Nature Based Learning Activities with a Focus on Water

Principal Investigator: Joseph O'Leary
Affiliation: Purdue University
Initiation Date: 1998
  • Provide and enhance the description of recreation participants in the nature based and specfiically
    water related learning activities
  • Segment recreation participants by applying the Three-step Procedural Model (activity packages,
    sociodemographic background, trip-related characteristics, environmental attitudes; and expenditure information)
  • Determine how the activity segments differ in terms of geographic, sociodemographic, travel trip, expenditure, attitudes and other characteristics
  • Provide recommendations for public and private recreation organizations interested in the outdoor
    recreation market
