Learn how the Arctic still thrives in the face of existential climate threats in new IMAX film
Doug Strickland is a writer for the Tennessee Aquarium.
CHATTANOOGA — At first glance, the Arctic seems an impossibly inhospitable place, a frigid wasteland of extremes in which nothing can survive.
Only one-quarter of this vast polar region at the top of the world is made up of land. The rest is comprised of a glacially cold ocean capped by vast stretches of ice.
Despite its harsh conditions, life has found a way to endure — and even thrive — in the Arctic. Audiences will meet just a few of the Arctic’s charismatic residents on Jan. 11, 2024 when the Tennessee Aquarium IMAX 3D Theater debuts a new giant-screen film, Arctic 3D: Our Frozen Planet.

Tennessee Aquarium welcomes 2,500 baby lake sturgeon as restoration effort turns 25 years old
Casey Phillips is a communications specialist at the Tennessee Aquarium in Chattanooga.
CHATTANOOGA — The approach of summer coincided with the arrival of thousands of juvenile lake sturgeon in the Tennessee Aquarium Conservation Institute.
Biologists at the Aquarium’s freshwater field station welcomed 2,500, 2-inch babies into their care. After a steady diet of bloodworms and brine shrimp, bringing the fish to at least 6 inches, they will be reintroduced into the Tennessee River.
These tiny fish hold tremendous promise. Adult lake sturgeon may reach lengths of 8 feet and live 150 years.
“They start out really small, so it’s shocking to think how big they can get,” says reintroduction biologist Sarah Kate Bailey. “The first year of life is when they grow the quickest.
“They grow so fast while we have them here. You’ll go home for the day, come in the next morning, and they look like they’ve grown overnight.”

Tennessee Aquarium floats citizen-scientist app to extend the reach of public research

So you want to be a citizen scientist? There’s a new app for that!
The Tennessee Aquarium Conservation Institute wants to assess the status of various fish populations throughout the Southeast so it released a new app to help outdoor folks and anglers identify the fish they spot, report the sighting, and enter their discoveries into a regional fish database.
The Freshwater Information Network (FIN) accepts and includes data for three major watersheds: The Tennessee and Cumberland rivers, and Mobile Bay.
Tennesseans may be familiar with the two rivers, but may think of Mobile Bay as a distant place with no connection to them, but its headwaters touch Tennessee in the Conasauga River. With its geographic isolation, the Conasauga is home to species of fish found nowhere else in the world.
