Remove Constraints To Study Microplastics At Depth

Studies suggest that 99.8% of oceanic plastic sinks below the ocean's surface. Until now, microplastics sampling equipment either only skimmed the water’s surface or required large and expensive research vessels with industrial deployment capabilities for below-surface sampling.

Ascension is a portable and tethered instrument that collects filtered microplastic samples down to 400 m depths from the side of a small vessel or fixed installation. Filtering water directly in situ, Ascension significantly increases your sample collection capabilities and reduces contamination. 

Easily collect plastics in the ocean

Easily collect filtered samples down to 400m even from the side of a small vessel like a dinghy or fishing boat.

Monitor plastics in marine protected areas

Attach to fixed installations like buoys, docks, or wastewater and stormwater outfalls for time series studies.

Use real-time interface to study plastics in the ocean

Measure depth, temperature, salinity, flow rate and total volume filtered in real-time without any coding or confusing terminal commands. 

  • Operate in real-time deployment mode or upload an automated mission for autonomous time-series sampling 

  • Minimize filter handling and potential contamination by filtering directly in situ  

  • Recharge the battery to maximizes deployment time and reduce primary battery waste

  • Manually lower and raise through the water column by hand with a real-time communication tether or fix to existing infrastructure using standardized mounting points
