Ascension Automated Depth Sampler
for Microplastics
Easily monitor freshwater and marine microplastic pollution down to 400 meter depths
Remove Barriers To Collect Microplastics At Depth
Microplastic pollution threatens freshwater and marine environments. To inform and monitor effective solutions, researchers and community scientists need more reliable data.
Since studies suggest that 99.8% of oceanic plastic sinks below the ocean's surface, it's crucial to collect and analyze microplastics at depth—something that has traditionally been extremely challenging.


Easily Monitor Microplastic Pollution
Ascension is a portable, automated instrument capable of collecting 7 separate filtered microplastic samples per deployment down to 400-meter depths from the side of a small vessel or fixed installation. Filtering water directly in situ, Ascension significantly increases microplastic monitoring capabilities.
Collect Reliable Data
Operate in real-time deployment mode or upload an automated mission for autonomous time-series sampling
Avoid sample contamination risks with in-situ filtration
Recharge the battery to maximize deployment time and reduce primary battery waste
Manually lower and raise through the water column by hand; no need for winch systems
Capture conductivity, temperature, salinity, depth and filtration volumes in real time with the on-board CTD sensor and flow meter
Easy for anyone to use; no confusing terminal commands or highly technical training required
Collect up to 7 samples in a single deployment

Automation, real-time sensing capabilities and in-situ filtration

Case Studies
Ascension for National Microplastics Monitoring Framework
In collaboration with the National Research Council of Canada, Ascension is being used to monitor microplastics across Canada and establish a national microplastics monitoring framework.
Ascension Helps to Uncover Microplastic Exposure in Humpback Whales
Researchers from the University of British Columbia use Ascension off the coast of Vancouver Island to study microplastics and marine mammals.
