Photo Gallery

The following images were selected to provide a glimpse of typical conditions inside ballast tanks, as well as sampling procedures used during the Great Lakes NOBOB Assessment Project. We would like to thank all vessel owners, operators, officers and crew members for their participation and cooperation, without which this project would not have been possible. Photos are copyright-free and may be downloaded for public use, but it is requested that credit be given to the Great Lakes NOBOB Project Team.
