NYC/NJ Aquatic Vertebrate Environmental DNA (eDNA) Project
We aim to help advance eDNA for monitoring ocean life. Our research focuses on marine fish populations in New York and New Jersey. We have also applied eDNA to marine mammals, terrestrial vertebrates, twilight zone ocean (depth 500m), fresh water ponds and streams, and in diverse sites from NYC’s Central Park to Sea of Galilee in Israel.
Why eDNA? Ocean life is largely hidden from view. Traditional surveys for marine animals are often costly, time- and capital-intensive, needing special equipment and trained personnel. So surveys are relatively sparse, and many regions remain unexplored.
eDNA offers a low-cost, low-impact technology to complement traditional surveys, including in difficult-to-survey environments, for protected species, and if pandemics or other events curtail routine surveys. eDNA will help monitor impacts of human activities, weather and climate, conservation efforts, and will aid research and exploration.

In collaboration with Monmouth University and New Jersey Department of Environmental Protection, we recently completed a one year study of eDNA and bottom trawl assessments of marine fish. We found the two technologies were largely concordant on marine fish diversity, seasonality, and relative abundance (link to article ICES J Marine Sci 2020, also see Science online coverage by Erik Stokstad).
Together with Monmouth University, we hosted the first National Conference on Marine Environmental DNA, November 29-30, 2018. The Conference included approximately 100 American ocean scientists and associated stakeholders, including representatives from academe, federal, state, and local governments, non-governmental organizations concerned with marine environment, and the private sector. The strong sense of the meeting was “eDNA works–let’s get going.” The Conference Final Report and press release summarize the conference proceedings and outline concrete steps forward.
