August 16, 2024 — When I tell my friends that I’m going to collect environmental DNA samples in the Northeast Canyons and Seamounts Marine National Monument, their first question is always: Where is that?
Northeast Canyons and Seamounts Marine National is a highly protected area located about 130 miles east-southeast of Cape Cod, Massachusetts. It is similar in size to Connecticut. President Obama designated this area as the first marine national monument in the Atlantic Ocean in 2016.
NOAA shares management responsibilities with the U.S. Fish and Wildlife Service for activities and species within the monument. It is a relatively undisturbed environment, which could be called a true ocean wilderness. The chief scientist of this research expedition, Peter Auster, is a research professor emeritus at the University of Connecticut and a senior research scientist at Mystic Aquarium. When Peter asked me if I’d be interested in sailing together to collect environmental DNA samples from the monument, I answered with an enthusiastic yes.
An interdisciplinary research group mustered aboard R/V Connecticut. Peter Auster and others scuba dove to deploy baited remote underwater video cameras to study apex predators. Meta Miner and Mael Glon from U.S. Fish and Wildlife Service conducted seabird surveys. Mary Beth Decker of Yale University used a specialized net to collect and identify gelatinous animals.
And of course, I collected seawater samples for eDNA metabarcoding analysis to study biodiversity in the monument, including fish and marine mammals.
Besides the fascinating habitat we studied, this expedition offered unique research opportunities for me.
