GLSC Field Season 2017 Photo Edition
During the 2017 field season, USGS Great Lakes Science Center scientists from across the basin took photos of their research and the unique sites they encountered while in the field. Below is a sampling of standout photos from our field scientists.

Enjoy this glimpse into the work of the GLSC science team that is generating scientific information to restore, enhance, manage, and protect the living resources and their habitats in the Great Lakes basin ecosystem! If you would like to use any of the photos, just let us know (email Josh Miller at joshuamiller@usgs.gov).
