In a groundbreaking application of aerial technology, researchers have turned to drones to monitor the health of whales in one of the most remote ecosystems on Earth: the Arctic Ocean. By collecting respiratory samples — known as “blow” — from humpback, sperm, and fin whales, scientists have detected the presence of a potentially deadly virus for the first time in Arctic waters. This innovative method promises a new era of non-invasive wildlife health surveillance and raises concerns about pathogen spread in a rapidly changing climate.

How Drones Revolutionized Whale Health Monitoring
Studying whales — especially in the remote and harsh conditions of the Arctic — has long posed logistical and ethical challenges. Traditional methods typically involve capturing animals for biopsy or relying on stranded specimens, both of which can be invasive or limited in scope. Scientists, however, have recently used drones equipped with sterile Petri dishes flown just above surfacing whales to collect their exhaled breath.
When whales break the surface to breathe, they expel a plume of air mixed with microscopic droplets from their respiratory systems. These droplets carry genetic and microbial material, offering a window into the animals’ health without distressing them.
First Evidence of Cetacean Morbillivirus in the Arctic
The cutting-edge sampling technique allowed researchers to detect cetacean morbillivirus — a highly infectious virus known to cause severe disease in marine mammals — circulating above the Arctic Circle. The virus has previously been linked to mass mortality events in whales, dolphins, and porpoises in other ocean regions, but its presence in the northernmost waters is unprecedented.
Cetacean morbillivirus can damage the respiratory, neurological, and immune systems of infected animals, making populations vulnerable to disease outbreaks and heightened mortality. The discovery of this pathogen so far north raises questions about disease transmission and ecological stressors in these once-isolated ecosystems. Smithsonian Magazine
The Study and International Collaboration
The research, published in BMC Veterinary Research, involved collaboration among institutions including King’s College London, The Royal (Dick) School of Veterinary Studies, and Nord University — illustrating the interdisciplinary nature of modern marine pathogen surveillance. Researchers collected more than 70 blow samples from whales across regions including northern Norway, Iceland, and Cape Verde, capturing respiratory data that traditional methods might miss.
By sampling both cetacean blow and traditional biopsies, scientists were able to verify the presence of cetacean morbillivirus and other pathogens — including herpesviruses — highlighting multiple disease threats that could affect marine mammal populations. Smithsonian Magazine
Why This Matters: Arctic Health and Climate Change
The detection of cetacean morbillivirus in the Arctic has important implications for marine conservation, climate science, and global ecosystem health. As Arctic waters warm due to climate change, migratory patterns and species interactions are shifting, potentially facilitating pathogen spread into previously unaffected regions. The Star
Understanding how pathogens move through marine mammal populations — and how environmental stressors might exacerbate disease risks — is critical for species management and biodiversity conservation. Advanced monitoring methods, such as drone-based sampling, offer powerful tools for long-term surveillance in remote habitats where traditional research techniques are difficult or invasive. The Star
Benefits and Future Applications of Drone Surveillance
Drone technology offers several advantages over conventional sampling:
- Non-invasive: Drones collect respiratory samples without causing stress or physical harm to animals.
- Wide reach: Remote and hard-to-access regions like the Arctic become feasible research sites.
- Real-time data: Researchers can capture up-to-the-minute health information and respond quickly to emerging threats.
As marine ecosystems face compounding challenges — from climate change to human activities — innovative technologies like drone surveillance could become standard practice for wildlife health monitoring.
Conservation and Long-Term Research
Experts emphasize that continuous monitoring and expanded sampling are key to understanding the full impact of diseases like cetacean morbillivirus on Arctic whale populations. Long-term data could reveal how pathogen prevalence changes over time and how interconnected factors such as ocean temperature, migration, and human presence influence disease dynamics. The Star
In the future, drone-based surveillance may integrate with broader efforts in oceanography, climate modeling, and wildlife epidemiology — charting a path toward holistic marine health strategies.
