DURHAM, N.H.—Researchers at the University of New Hampshire have been awarded over $1.25 million from the Office of Naval Research and the National Oceanic and Atmospheric Administration to take a deeper dive on the impact of climate change on the dynamic marine ecosystems found in the Gulf of Maine in both New Hampshire and southern Maine.

“We know the Gulf of Maine is warming, and we know species are responding, but it’s important to know more broadly how communities are responding—from the seafloor to the surface—to give us a better snapshot of what food is available and how this could be affecting some of the core species in the Gulf of Maine like cod and terns,” said Nathan Furey, assistant professor of biological sciences.

The five-year project will integrate cutting edge technology with traditional fisheries sampling to determine the effects of environmental changes on the ecosystems in local and regional waters by focusing on both the Atlantic cod, which has held a long historical importance in the Gulf of Maine, and the common tern, which has a large breeding colony at the Isles of Shoals. Researchers will use high-tech modes of tracking to monitor the movements of Atlantic cod and terns. The team will use both passive and active acoustics to provide measurements of marine biodiversity in the areas where cod and terns are tracked. Environmental DNA, or eDNA, will be used to collect a variety of samples from the water column to measure DNA released from different species, which can be present in the water, the air and other surroundings. Researchers will also examine the diets of the Atlantic cod and terns by analyzing gut and fecal samples.

“We’re bringing together all these emerging technologies to get a better idea on what is happening on the bottom of the water column, where the cod live and feed, as well as at the surface, where the terns feed,” said Furey. “The terns are an important part of the larger picture because they are marine consumers and offer a unique perspective of what is happening in fish populations just by sampling what is available to them.”

Researchers hope their findings will help promote proper conservation and management in a rapidly changing Gulf of Maine by determining at what scales ecosystem components change and the best methods to detect such variation.

Collaborating institutes include the Gulf of Maine Research Institute and the Northeastern Regional Association of Coastal Ocean Observing Systems.

The University of New Hampshire inspires innovation and transforms lives in our state, nation and world. More than 16,000 students from all 50 states and 71 countries engage with an award-winning faculty in top-ranked programs in business, engineering, law, health and human services, liberal arts and the sciences across more than 200 programs of study. A Carnegie Classification R1 institution, UNH partners with NASA, NOAA, NSF and NIH, and received $260 million in competitive external funding in FY21 to further explore and define the frontiers of land, sea and space.
