Uncovering Whale Behaviours with New eDNA Sampling Technology

Passionate about protecting humpback whales, Amy Migneault is a PhD researcher at the University of Victoria who is collecting genetic information that can help to inform conservation management. Using environmental DNA (eDNA) sampling, an approach that captures the genetic material shed by whales into the water, she can monitor humpback populations without disturbing the animals or their habitats. 

To collect reliable eDNA samples, Migneault has turned to Ocean Diagnostics’ eDNA Surface Sampler.  

“The (eDNA) Surface Sampler is exactly what I was looking for: compact, reliable and easy to use from a boat,” says Migneault. 

As part of its mission to enable the ocean science needed to protect our planet from biodiversity loss, Ocean Diagnostics designed the eDNA Surface Sampler to improve sampling workflows and increase sample collection capabilities. 

Migneault’s research aims to validate eDNA sampling by comparing the results with tissue samples from the same individual whales. It will also expand genetic datasets by sampling previously unstudied individuals. 

Samples collected with the Surface Sampler are being analyzed in the University of Victoria’s Helbing Lab. Results are expected in 2026 and could enhance understanding of population structure, guide management decisions and inform broader marine conservation strategies. 

eDNA Sampling Provides a Non-Invasive Alternative  

While traditional whale genetics research often relies on invasive and difficult tissue biopsy sampling, eDNA sampling provides an alternative that scientists can use to collect genetic information from seawater instead of directly from animals. 

Ocean Diagnostics’ portable, battery-powered eDNA Surface Sampler is designed to efficiently collect eDNA from the water, supporting researchers working in remote or challenging marine environments. 

“It’s exciting to know that with the help of eDNA and tools like the Surface Sampler we can protect vulnerable species without causing them harm,” Migneault shares. 

eDNA Sampling Empowering Broader Conservation Efforts 

The implications of this study could extend beyond whale research. 

“These methods could eventually be used by citizen scientists and local communities to help protect a wide range of threatened marine species. The eDNA sampler makes this kind of accessible, non-invasive research possible,” Migneault explains.

As eDNA sampling becomes an increasingly important tool for biodiversity monitoring, innovations like the eDNA Surface Sampler are helping researchers collect high-quality data more efficiently in the field. 

“One of my favourite parts about this system is that it’s compatible with a wide range of filter types, making it easy to tailor to different project needs. It’s streamlined the sampling process in a way I couldn’t have done otherwise,” she illustrates. 

Bridging science, technology and conservation, Ocean Diagnostics’ eDNA Surface Sampler is advancing biodiversity monitoring so creatures like the humpback whale can be better understood and protected.
