Scientists say environmental DNA can detect whales and dolphins in New York waters.
- Results are some of the most promising to date in the open Ocean
- Massive renewable energy projects coming to the New York Bight could impact whales and dolphins
A team of scientists used an emerging genetic tool that analyzes including a wind energy auction for more than 488,000 acres in the New York Bight. There are many potential impacts from these developments to whales that the environmental community, industry, and state/federal authorities are aiming to address. WCS has been involved at state and national level dialogues as well as developing best practice guidance through the IUCN.
The use of emerging and novel techniques such as eDNA as demonstrated by the results of the current study in the NY Bight and other approaches can offer new insights as to whale presence and their prey in and around lease areas as offshore wind scales up along the eastern seaboard. More broadly, WCS increasingly uses eDNA in its conservation work, detecting critically endangered wildlife such as Swinhoe’s softshell turtle, in the Bolivian Amazon, and in some of the most rugged areas on the planet including Mt. Everest.
