eDNA Sampler - Environmental DNA Sampling

DNA SAMPLER - Environmental DNA Sampling

Environmental DNA (eDNA) sampling has revolutionised aquatic ecosystem monitoring by enabling the detection of genetic material shed by organisms into the environment. This non-invasive passive monitoring method allows for comprehensive biodiversity assessments without the need for direct observation, acoustic monitoring or capture.

Autonomous eDNA Multi-sampling for the Detection of Biological Genomic Signatures in Water

Our cutting-edge Autonomous eDNA Sampler is engineered to facilitate precise and efficient collection of eDNA samples in various aquatic environments. Key features include:

  • Automated Operation: Pre-programmed missions enable autonomous sampling, reducing the need for manual intervention and increasing operational efficiency.
  • Micro-Fluidic Architecture: This design minimizes reagent consumption and securely stores waste products for proper disposal, promoting environmental responsibility.
  • Sample Preservation: Utilizing RNAlater for sample preservation ensures the integrity of genetic material during long-term, unsupervised deployments.
  • Customizable Filter Materials: Various filter materials, such as polycarbonate and PVDF, are available to meet specific research requirements.
  • Optional Integrated Fluorometer: An optional 4-channel fluorometer (Chl-a, PC, PE, FDOM) provides real-time fluorescence measurements, adding valuable data layers.
  • Compact Design: Its portable form factor allows deployment from diverse platforms, including small boats and autonomous underwater vehicles.

Multi-sample eDNA Collection Made Easy

eDNA sampling offers a cost-effective and less invasive alternative to traditional biodiversity assessment methods. It facilitates early detection of invasive species, parasites, and pathogens, contributing to proactive environmental management.

eDNA sampling is a valuable tool for studying both prokaryotic and eukaryotic biodiversity in the water column.

Dartmouth Ocean Technologies has developed a portable, convenient solution for use in many data collection scenarios.

The programmable nature of the instrument allows for increased sampling resolution over long periods of time – ideal for time series studies​.

DNA can be extracted from filters using various commercial kits (i.e. Qiagen, BioMeme)​. The integrated multi-sample holder makes transporting the samples more convenient.

Environmental Monitoring Applications
  • Coastal and Offshore Site Assessments: Commissioning and decommissioning of various coastal and offshore work sites​:
    • Oil and Gas
    • Wind farms
    • Aquaculture
  • Targeted Organism Surveillance: Monitoring the environment for specific organisms of interest:
    • Harmful algae (i.e. Alexandrium sp.)
    • Parasites or pathogens
    • Indicator species
  • Molecular Analysis Compatibility: Collected samples are compatible with downstream molecular techniques, including quantitative PCR (qPCR), for detailed genetic analysis.
