Science: The Great Lakes Mapper (SiGL)
See where science is being conducted in The Great LakesSiGL Mapper
Students from Indiana University Northwest visited the Lake Michigan Ecological Research Station (GLSC, Chesterton, Indiana).
This Story Maps accompanies 4 peer-reviewed publications to provide a convenient and useful tool to access the information contained within these four peer-reviewed publications. The tree swallow data are easily visualized on a landscape scale, or more detail can be obtained by drilling down. These data are being used by States and EPA in their Beneficial Use Impairment (BUI) assessments. ...

An evaluation of the zooplankton community at the Sheboygan River Area of Concern and non-Area of Concern comparison sites in western Lake Michigan rivers and harbors in 2016
The Great Lakes Areas of Concern (AOCs) are considered to be the most severely degraded areas within the Great Lakes basin, as defined in the Great Lakes Water Quality Agreement and amendments. Among the 43 designated AOCs are four Lake Michigan AOCs in the State of Wisconsin. The smallest of these AOCs is the Sheboygan River AOC, which was...Olds, Hayley T.; Scudder Eikenberry, Barbara C.; Burns, Daniel J.; Bell, Amanda H.
EROD activity, chromosomal damage, and oxidative stress in response to contaminants exposure in tree swallow (Tachycineta bicolor) nestlings from Great Lakes Areas of Concern
Tree swallow, Tachycineta bicolor, nestlings were collected from 60 sites in the Great Lakes, which included multiple sites within 27 Areas of Concern (AOCs) and six sites not listed as AOCs from 2010 to 2014. Nestlings, approximately 12 days-of-age, were evaluated for ethoxyresorufin-O-dealkylase (EROD) activity, chromosomal damage, and six...Custer, Thomas W.; Custer, Christine M.; Dummer, Paul; Bigorgne, Emilie; Oziolor, Elias; Karouna-Renier, Natalie K.; Schultz, Sandra; Erickson, Richard A.; Aagaard, Kevin; Matson, Cole W.
Management implications of broadband sound in modulating wild silver carp (Hypophthalmichthys molitrix) behavior
Invasive silver carp (Hypophthalmichthys molitrix) dominate large regions of the Mississippi River drainage, outcompete native species, and are notorious for their prolific and unusual jumping behavior. High densities of juvenile and adult (~25 kg) carp are known to jump up to 3 m above the water surface in response to moving watercraft. Broadband...Vetter, Brooke J.; Calfee, Robin D.; Mensinger, Allen F.
