Dr. Bernie Kuhajda joined the Tennessee Aquarium Conservation Institute staff in May 2012 after 25 years at the University of Alabama, where he managed a museum collection of one million specimens of preserved fishes from all around the world. Though his studies of fishes and other aquatic organisms have taken him around the United States, Mexico, and Central Asia, his particular expertise is surveying and monitoring threatened and endangered species from aquatic systems in the Southeast, in part to help evaluate the effectiveness of conservation programs. He currently teaches weekend courses at the University of Alabama Gadsden Campus and on the main campus in Tuscaloosa every summer. He serves on multiple USFWS Recovery Teams/Groups for endangered and threatened species.
Imagine possessing untold wealth but lacking the means to keep it safe. That is the broad-strokes reality faced by those of us who work to protect the Southeast’s rich aquatic biodiversity.
Our waterways are home to an incredible natural profusion, one that is unrivaled in the temperate world. More than 1,400 aquatic species reside in waterways within a 500-mile radius of the Tennessee Aquarium’s home in Chattanooga, including about three-quarters (73.1 percent) of all native fish species in the United States. More than 90 percent of all American mussels and crayfish species live within that same area, as do 80 percent of North America’s salamander species and half of its turtle species.
Southern Fried Science has at the forefront of trying to debunk fake news, such as faux documentaries about mermaids or giant sharks. In their article “Fish tales: combating fake science in the popular media” Andrew Thaler and David Shiffman asked that:
“scientists familiarize themselves with common sources of misinformation within their field, so that they can be better able to respond quickly when factually inaccurate content begins to spread”
Happy FSF! As some of you may know (and for those who don’t), I study the bottom of the ocean, and I do so primarily using innovative technology to image the seafloor (e.g., Wormcam). The interesting work I’ve conducted has resulted in me having the opportunity to present my work to a larger lay audience, in the form of a TEDx presentation.

I am giving my TED talk with my good buddy and colleague Steve Sabo. In our talk, “A Picture is Worth a Thousand Worms”, Steve & I will illustrate the significance of the ocean floor through advancements in underwater camera technology and data visualization, making complex science more accessible for everyone.

A few years ago, we organized a group of marine conservation scientists to meet to discuss, and list, the most urgent issues that need to be studied. The resulting paper came up with 71 questions which urgently needed to be addressed, because a lack of an answer was severely impeding marine conservation. However, during this exercise we also came up with a list of other questions – these were issues that were controversial, that everyone knew were important, but were unwilling to raise as being an issue. These were the Voldemorts of marine conservation questions (they that shall not be named), the elephant (or elephant seal) in the room questions …. or as we more aquatically termed them: “the kraken in the aquarium” questions.
A great white shark nursery in the North Atlantic that was discovered in 1985 south of Cape Cod in the waters off Montauk, New York has received renewed attention due to the increased activity of white sharks off cape cod in recent years. The nursery was first documented in 1985 by Casey and Pratt who deduced the presence of a nursery based on the number of juvenile sightings and landings in the area. This work was followed up recently by OCEARCH (an organization dedicated to generating scientific data related to tracking/telemetry and biological studies of keystone marine species such as great white sharks), which tagged and tracked nine infant great whites to the nursery, located a few miles off Montauk.

Human induced climate change is real. It feels weird that I have to say that, but the overwhelming body of evidence suggest human activity post the industrial revolution is having irrevocable damage on our environment. One of the major implications of climate change is the loss of the polar glaciers (and subsequent sea level rise).
The oceans belong to all of us. With this simple statement in mind, the Oceanography for Everyone (OfE) project was launched with the goal of making ocean science more accessible. One of the biggest hurdles in conducting ocean science is instrumentation costs, and 4 years ago the OfE team began trying to make one of the most basic ocean science tools, the CTD (a water quality sensor that measures Conductivity-Temperature-Depth), cheaper… much, much cheaper!
