Mind the Map
SEGMENT 1 | Cleveland, Ohio
While current charts of the Great Lakes have aided navigation for decades, they’re based on a patchwork of data gathered using primitive survey methods like lead-line surveys, in some cases around 80 years ago. The charts are low-resolution, indicating only depths, often miles apart—but that’s changing.
There’s a new effort to map the Great Lakes bottomlands in unprecedented detail using state-of-the-art sonar. At the heart of the effort, is the U.S. National Oceanic and Atmospheric Administration’s vessel, the Thomas Jefferson.
There are multiple sonars on the Thomas Jefferson—or “TJ” for short—and on the TJ’s two launches, which also conduct hydrographic surveys. The sonars are sure to reveal details and features that have never been documented before, giving a whole new view of the depths of the Great Lakes.
What does the system look like, and how is the data gathered? Great Lakes Now contributor David J. Ruck spent a day on the Thomas Jefferson to find out.

SEGMENT 2 | Toronto, Ontario
The Royal Ontario Museum (ROM) is Canada’s largest museum and is comparable to the British Museum in London, England, or the Smithsonian in Washington, D.C.
More than a million people a year visit the ROM to enjoy over 13 million artworks, cultural objects and natural history specimens showcased across 40 gallery and exhibition spaces.
But behind the scenes, the ROM’s fish-specimen collection is one of the top 10 fish collections in North America. It includes 110,000 jars containing about 1.5 million individual specimens spanning more than 7,500 species of fishes. Roughly, one in five species of fish globally are represented, from both freshwater and marine environments.
But the ROM fish collection isn’t housed in their iconic downtown Toronto location. With over 100,000 jars filled with flammable liquid, the entire collection was moved out of the museum basement to a secure — and secret — location outside of the city.
Erling Holm curated the collection for 44 years and recently passed the reins to Nathan Lujan. Both men share with Great Lakes Now why natural history collections play such a critical role in understanding Earth biodiversity and how it is changing over time.

The Catch: News about the Lakes You Love
SEGMENT 3 | Chicago, Illinois; Syracuse, New York; Cleveland, Ohio
Keep up with the Great Lakes’ biggest issues. Find out how environmental challenges are impacting your enjoyment of the outdoors and the health of the ecosystem. Go beyond the headlines with reporters from around the region.
This new segment – The Catch – in our award-winning PBS program will keep you in the know. This month, stories from our partners with the “Water’s True Cost” project.
First, head to Chicago where Daily Herald Climate Reporter Jenny Whidden is looking into the causes of lightning bug population declines. Whidden says the issue is part of a larger problem of declining insect populations in general, but she also has some suggestions on what you can do to help attract and protect lightning bugs in your own backyard.
Next, Syracuse.com Climate Reporter Glenn Coin talks about a historic transfer of land back to the Onondaga Nation.The move marks the first time that land has been returned directly to a tribal entity in the state of New York. The land transfer is part of a settlement involving Honeywell International, a company that polluted and is now helping to restore Onondaga Lake.
Finally, GLN’s Lake Erie Contributor James Proffitt rounds things out with news about the launch of an innovative freighter from the Cleveland-based Interlake Steamship Company. The ship is named the Mark W. Barker and is the first American made bulk cargo carrier constructed on the Great Lakes in nearly 40 years.
