Guardian Angels of the Deep: How Drones and Thermal Imaging Are Saving North Atlantic Right Whales
In the vast, cold waters of the North Atlantic, a quiet battle for survival is being waged. The world’s most endangered marine mammals, is teetering on the brink of extinction. But hope is emerging from an unlikely source: drones and thermal imaging technology.
gina Lonati, a researcher at the University of New Brunswick (UNB), has dedicated her career to studying these majestic creatures. Her journey began in 2017, a devastating year for the species. “In total, 17 of them died and no births were recorded,” Lonati recalls. This grim reality spurred her to enroll in a doctorate program at UNB, where she has since developed groundbreaking methods to monitor and protect these whales without disturbing them.
A Technological Breakthrough
Lonati’s research focuses on remote sensing, a non-invasive technique that uses drones to track whales and capture thermal images when they surface. “This type of technology was used in land environments but not really in marine environments since thermal images do not allow us to see the heat under the surface of the water,” she explains.
The challenge lies in the whales’ behavior. North Atlantic right whales spend long periods underwater, making them difficult to monitor. “We had to be a little patient and creative, but we finally managed to find a way to take their temperature through their blow,” Lonati says. This innovative approach allows researchers to gather critical data on the whales’ health and behavior without direct contact, reducing stress on the animals.
Why North Atlantic Right Whales Need Our Help
The plight of the North Atlantic right whale is dire. Once hunted to near extinction by commercial whalers,these whales now face threats from ship strikes,fishing gear entanglement,and climate change. With fewer than 400 individuals remaining, every effort to protect them is crucial.
Lonati’s work is part of a broader push to save the species. Her research not only provides valuable insights into the whales’ physiology but also helps inform conservation strategies. by understanding their behavior and health, scientists can advocate for measures like slower ship speeds and modified fishing practices to reduce human impact.
A Glimmer of Hope
Despite the challenges, Lonati remains optimistic. Her work has already demonstrated the potential of technology to revolutionize marine conservation. “Drones make it possible to track whales remotely and capture thermal images when they come to the surface,” she notes. This non-invasive method is a game-changer, offering a way to study these elusive creatures without disrupting their natural behavior.
As Lonati prepares to present her doctoral thesis, her research stands as a testament to the power of innovation and perseverance. The North Atlantic right whale might potentially be on the brink, but with dedicated scientists like Lonati leading the charge, there is hope for their survival.

North Atlantic Right whales: A Struggle for Survival Amidst Entanglement Risks
The North Atlantic right whale, one of the most endangered marine species, continues to face significant threats from human activities, especially entanglement in fishing gear. Researcher Gina Lonati, who has dedicated her work to studying these majestic creatures, reveals alarming statistics and insights into their plight.
A Glimpse into the Lives of Right Whales
Using drones and underwater sensors, Lonati has been able to observe and document the behavior of north Atlantic right whales in their natural habitat. The drones, flying five to seven meters above the whales, provide a unique perspective on their lives.
“It really offers a unique perspective,” Lonati explains. “Since remote detection is not intrusive, we can see the whales being themselves, being mothers, being happy.”
One such heartwarming moment captured by Lonati shows two whales hugging and playing together on the surface of the water.This rare glimpse into their social behavior highlights the importance of protecting these gentle giants.!information on how you can contribute to conservation efforts,visit North Atlantic Right Whale Conservation.

The Silent Struggle of right Whales: A Tale of Entanglement and Survival
The first time marine researcher Gina Lonati encountered a North Atlantic right whale, the sight was both awe-inspiring and heartbreaking. The whale’s tail bore deep scars from entanglement in fishing gear, a stark reminder of the dangers these majestic creatures face. “I cried. Then I calmed down and went back to my research,” Lonati recalls. This poignant moment marked the beginning of her journey to document the plight of these endangered giants.
Since that initial encounter, Lonati’s research has revealed a disturbing trend: a growing number of right whales bear severe scars from entanglements. These injuries are not just superficial; they often lead to life-threatening infections,impaired mobility,and,in many cases,death.
One of the most harrowing cases Lonati documented was Hercules, a hybrid whale she encountered in 2021. “He was struggling and bleeding from his tail,” she remembers. Hercules was severely entangled in fishing ropes, a situation that left him fighting for survival. Tragically, Hercules has not been seen since 2021 and is presumed dead.
The Growing Threat of Fishing Gear
Entanglement in fishing gear is one of the leading causes of mortality for North Atlantic right whales, a species already teetering on the brink of extinction. According to recent studies, over 85% of right whales have been entangled at least once in their lives.The scars left behind are not just physical; they are a testament to the ongoing struggle these animals face in their natural habitat.
The problem is exacerbated by the increasing overlap between whale migration routes and commercial fishing areas. As whales travel through these zones, they often become ensnared in lobster and crab traps, gillnets, and othre fishing equipment. The ropes and lines can cut into their flesh, causing deep wounds and restricting their ability to swim and feed.
A Call to Action
The plight of right whales like Hercules underscores the urgent need for action. Conservationists and researchers are calling for stricter regulations on fishing practices, including the use of ropeless gear and seasonal fishing closures in critical whale habitats. These measures could significantly reduce the risk of entanglement and give these endangered animals a fighting chance at survival.
Lonati’s work is a powerful reminder of the impact human activities have on marine life. “Every scar tells a story,” she says. “And it’s up to us to change the narrative.”

Thermal Imaging Could Revolutionize Right Whale Injury Detection
The north Atlantic right whale, one of the most endangered marine species, faces numerous threats, including ship strikes and entanglement in fishing gear. Researchers like Gina Lonati are exploring innovative methods to protect these majestic creatures, and thermal imaging is emerging as a promising tool to detect injuries and inflammation caused by collisions with ships.
A New frontier in Whale Conservation
Gina Lonati, a dedicated researcher, is investigating whether thermal imaging can reveal localized increases in body heat in right whales after they’ve been struck by ships. “I would like to find out if thermal imaging of right whales could allow us to know, when whales have been struck by ships, whether the inflammation would cause a localized increase in heat in a certain part of their body,” she said.
This groundbreaking approach could provide a non-invasive way to assess the health of these whales, enabling quicker interventions and potentially saving lives. By analyzing thermal data, researchers hope to identify injuries or illnesses that might or else go unnoticed.
The Role of Calluses in Identification
Right whales are uniquely identifiable by the calluses on their heads, which function like fingerprints. These thick, white patches of tissue are not only crucial for individual identification but also serve as a visual record of past injuries. Many North Atlantic right whales bear scars from previous entanglements, highlighting the urgent need for better monitoring and protection strategies.
the Path Forward
Lonati’s work is part of a broader effort to collect more data on right whale health. By refining thermal imaging techniques, researchers aim to develop tools that can quickly and accurately determine when a whale is injured or sick. This could revolutionize conservation efforts, allowing for faster responses to emergencies and reducing the risk of fatal outcomes.
