Ascension eDNA Depth Sampler
Easily monitor freshwater and marine biodiversity down to 400 meters from a small boat
With Ascension, anyone, anywhere can collect reliable eDNA data at anytime

Advance Your Biodiversity Monitoring
Marine pollution, invasive species, climate change and other human activities threaten biodiversity and life below water (SDG 14). Environmental DNA (eDNA) sampling is a simple, cost-effective and non-destructive method to monitor biodiversity loss and the early detection of invasive species, parasites and pathogens.
Ocean Diagnostics designed Ascension eDNA to help researchers, park operators and community scientists to collect reliable eDNA in freshwater and marine environments without needing large vessels, crews, additional equipment or specialized technical training.
Dive deeper into Ascension eDNA sampling capabilities!
Put Ascension's innovative and smart design to work for you!
Collect up to 7 separate samples per deployment or include replicates for every deployment
Eliminate sample contamination risks with in-situ filtration

Testimonials
"You can just go out with the Ascension device and sample quite easily on the tender itself. It opens a lot more doors for end users to implement eDNA into their (biodiversity) monitoring.”
Marcelle Ayad
Research Analyst | Minderoo Foundation
“Ascension took away a barrier for the skills needed for sampling. It is foolproof compared to other equipment. I was really excited. I can’t believe the data we’ll get!"
Dr. Susan Anthony
Project Manager | SeaChange Society
“The best place to look for information is going to be at depth. Ascension is really one of the only ways that we can get our hands on those deeper samples given the platforms of opportunity available to us for this project.”
