ALPENA, MI. – The Thunder Bay National Marine Sanctuary has new programming for Alpena. The latest exhibit, “Science on a Sphere”, features a carbon fiber globe. The globe is suspended from wire, at six feet in diameter!

The Sanctuary reopened to the public after a two year closure in April of 2022.  With the recent reopening, the Sanctuary is continuing to add new learning resources for the public to enjoy.  Maritime Archeologist, Cassandra Sadler, said the exhibit is an “excellent resource” for the sanctuary and that she expects it to bring many additional students.
“It allows us to make complicated environmental and physical topics like earth and other planets in a simple and interactive way for students to understand them.” said  Caleb O’Brien, Maritime Archeologist. Sanctuary ambassadors will hold an interactive presentation every Thursday with the display.
