Descrição: DNA DIVERS - global eDNA citizen science project [grant submissions closed but other sites welcome]
This is an exciting opportunity for interested / motivated divers to participate in DNA Divers—a citizen science project that connects recreational divers with marine researchers to explore underwater biodiversity using environmental DNA (eDNA).
Using our research contacts and Professor of Marine Biodiversity at Liverpool John Moores University, Stefano Mariani, DNA Divers empowers volunteers to help shape and drive marine research. Using a device called the metaprobe, divers collect trace DNA left behind in the water by marine life—no lab experience or training needed. The unique part: volunteers will help define the research questions, choose dive locations, and collect samples.
We have already assembled a list of sampling locations where our communities could collect eDNA samples, following into a grant application due in June.
However, we welcome other applications and expressions of interest from anyone wanting to get involved!
What we are looking for, and what you need:
• Special or underexplored dive sites
• Sampling plans that can happen within 12 months
• Willingness to work independently with basic materials
• Feel free to recommend aspiring citizen science / scientific divers in
your network as well
• Access to a 3D printer, bleach, falcon tubes, etc.
Please note: this is a fully autonomous citizen science initiative. Materials and equipment are not provided, but you will receive complete protocol documentation and guidance after you have registered initial interest. Please see Jenn or Erik for more information, and to get the sampling list and instructions.
Certification requirement: Rec 1 or Fundamentals
