News Summary
Researchers at Mississippi State University are utilizing drones with thermal imaging technology to monitor dolphin health in the Mississippi Sound. Led by Holley Muraco, this project aims to establish a baseline for dolphin behavior and health while highlighting their role as indicator species for marine ecosystem health. The study compares dolphin observations in murky Mississippi waters with those in the clearer Caribbean and Florida regions, ultimately seeking to address environmental challenges facing these marine mammals.
Starkville, Mississippi – Mississippi State University Researchers Use Drones to Monitor Dolphin Health in the Mississippi Sound
Researchers at Mississippi State University are utilizing aerial drones equipped with thermal imaging technology to enhance dolphin studies in the Mississippi Sound. This innovative approach offers a unique perspective, allowing research teams to observe dolphin movements and skin conditions that are challenging to detect from the shore.
The project is spearheaded by Holley Muraco, an assistant research professor at the Coastal Research and Extension Center. Initial pilot studies, which focused on monitoring sea turtles near Cat Island, showcased the level of detail that drones can capture, prompting researchers to expand their efforts to include dolphin observation.
Collaboration is a crucial aspect of this initiative, as the project has led to partnerships with organizations such as Coral World in the U.S. Virgin Islands and Theater of the Sea in the Florida Keys. Researchers are currently comparing dolphin observations between the clear waters of the Caribbean and Florida’s sediment-rich mangrove lagoons against the murky conditions found in the Mississippi Sound.
The murkiness in the Sound is primarily attributed to its nutrient-rich waters, which can complicate visibility and hinder dolphin observation. Muraco points out that dolphins are permanent residents of the Mississippi Sound, highlighting their vulnerability to local environmental challenges like pollution and runoff.
Within marine science, dolphins are recognized as an “indicator species,” meaning their health can provide insights into the overall water quality and ecosystem health. The presence of skin lesions in dolphins could serve as a warning sign of environmental issues that may also impact human seafood consumption in the Gulf of Mexico.
This research aims to establish a baseline for dolphin health and behavior, facilitating long-term monitoring of any changes over time. By exploring the interconnections between environmental, animal, and human health, the study suggests that dolphins might act as an early warning system for environmental problems.
Described as “the canary in the coal mine” for environmental monitoring, dolphins serve as a crucial link between the ecological health of the Mississippi Sound and the safety of human interactions with the Gulf’s marine life.
