Microbial communities of the Laurentian Great Lakes reflect connectivity and local biogeochemistry

16S rRNA V4 and V4-V5 region sequences representing multiple stations on each of the five Laurentian Great Lakes collected during the U.S. EPA’s Great Lakes National Program Office Spring and Summer Surveys aboard the R/V Lake Guardian in 2012 and 2013.
