New Hampshire’s coastline is shorter than most states’ suburbs. At roughly 18 miles, it is smaller than the runway sprawl at some Midwestern airports. That tiny stretch of shoreline, plus the brackish maze of Great Bay, drives a research effort that is now receiving roughly $1.2 million in new funding through the New Hampshire Sea Grant program based at the University of New Hampshire. The 2026 to 2027 funding cycle is built around six projects that take on some of the thorniest questions facing the state’s coastal economy and ecology, according to the NH Sea Grant program at UNH. The questions range from how PFAS chemicals climb the marine food web to whether New Hampshire can grow nori seaweed on long lines.

The announcement matters even for Granite Staters who never set foot in a kayak. Oyster farming in Great Bay is a multimillion-dollar industry. Commercial fishing out of Portsmouth and Rye supplies restaurants up and down the Seacoast. Tourism dollars follow clean estuaries, healthy eelgrass beds, and the kind of working waterfront that towns like Portsmouth and Newington have spent decades protecting. The research projects funded in this cycle target the science that keeps each of those activities viable.

What the funding cycle looks like

NH Sea Grant operates on a two-year funding rhythm. Researchers apply for one or two-year projects each cycle, with awards capped at $100,000 per project per year plus a required 50 percent non-federal match. The current 2026 to 2027 cycle officially runs February 1, 2026, through January 31, 2028. Across the six funded projects in this cycle, NH Sea Grant is investing approximately $1.2 million from a combination of National Oceanic and Atmospheric Administration support and non-federal matching funds.

The Sea Grant model is built on partnership. UNH hosts the program, but the research teams pull in Dartmouth College, other universities, state agencies, oyster growers, fishermen, and community organizations. The 50 percent match requirement keeps the projects tied to real-world stakeholders. If a researcher cannot get a state agency, an industry partner, or an academic department to put up matching dollars, the project does not get funded.

That structure is one reason NH Sea Grant has avoided some of the political volatility that has rattled federal research budgets in recent years. Sea Grant funding “held steady in 2026,” according to industry reporting, with Congress appropriating $80 million for the national program and $14 million for Sea Grant aquaculture. New Hampshire’s share is small in dollars and outsized in impact precisely because the state’s coastline forces the research to be focused.

PFAS in the food web

Among the most consequential projects in the new cycle is research led by Dartmouth College’s Celia Chen on PFAS bioaccumulation in marine food webs in a New England estuary. PFAS, the so-called forever chemicals associated with firefighting foam, nonstick coatings, and industrial discharge, have been a public health story in New Hampshire for more than a decade. The Conservation Law Foundation has been in active litigation with the federal Environmental Protection Agency over PFAS discharge from the Manchester wastewater treatment plant, a case our team has covered in detail.

Chen’s project moves the conversation from drinking water and surface water into seafood. The research will assess levels of PFAS in Great Bay wildlife and measure the transfer of PFAS in laboratory experiments with organisms across the food web. The result, eventually, is a clearer picture of whether eating oysters, fish, or shellfish from places like Great Bay carries a measurable PFAS exposure risk, and at what levels of contamination that risk becomes material.

For Granite Staters who fish recreationally or buy locally harvested seafood, the answer matters. For state regulators trying to set advisories that are scientifically grounded rather than politically convenient, the data will provide a foundation. For oyster growers worried about consumer confidence, the project is a way to get ahead of a question that is going to be asked.

Vibrio and oyster aquaculture

A second UNH project, led by Cheryl Whistler, is digging into one of the oyster industry’s most persistent problems. Vibrio bacteria, particularly the strain known as ST36, can sicken consumers who eat raw shellfish. Outbreaks linked to New England oysters have closed beds and triggered expensive recalls in recent years.

Whistler’s team will investigate the actual risk of Vibrio introduction through transport of oyster seed, the small juvenile oysters that growers buy from hatcheries and move to estuary upwellers to mature. The research will explore mitigation strategies including salt relay, in which oysters are exposed to higher-salinity water before harvest to reduce bacterial loads, and the use of microbiome science to understand whether the natural community of microbes on an oyster can be managed to resist Vibrio.

The most consumer-facing piece of the project is detection. The research will improve laboratory assays for distinguishing ST36 from other Vibrio strains that do not pose the same human health threat. If state regulators can tell the difference faster, they can avoid blanket closures that punish growers across an entire estuary when the actual problem is localized.

Lumpfish, eelgrass, and seaweed

The remaining projects in the cycle expand the research portfolio in directions that matter for both science and small business. A team led by Elizabeth Fairchild at UNH is leading the Lumpfish Mapping Project, known as Team LuMP. The goal is to describe and map the range of lumpfish in the Gulf of Maine and create an online interactive map for fisheries professionals, researchers, and the public. Lumpfish matter because aquaculture operations use them as biological control agents against sea lice on farmed salmon. Knowing where wild lumpfish populations exist, and how healthy those populations are, is essential to managing the species responsibly.

A separate project focuses on eelgrass dynamics in Great Bay Estuary. Eelgrass beds are the foundational nursery habitat for juvenile fish and shellfish across the estuary. They have been in long-term decline, with periodic recoveries. Understanding the conditions that allow eelgrass to thrive, particularly nitrogen loading from upstream watersheds, is central to setting realistic restoration targets for the entire Great Bay system.

The seaweed project, focused on diversifying New England seaweed aquaculture through longline nori production, is a small-scale economic development effort that could become more important if it pencils out. Nori, the seaweed best known as the wrap around a sushi roll, is overwhelmingly imported. A New England nori industry built on longline production could open a new line of work for fishermen and farmers willing to experiment.

Why this connects to the rest of New Hampshire

Coastal research can sometimes feel disconnected from the rest of the state. In New Hampshire, that connection is closer than it looks. Great Bay is fed by rivers that drain a watershed reaching most of the southern part of the state. PFAS that lands in a Manchester wastewater outfall eventually moves toward the Atlantic. Climate change pressures that are reshaping rainfall patterns across the state, as our reporting on the Dartmouth rainfall study explained, do not stop at the coastline. Nitrogen loading from interior agricultural and residential development drives the same eelgrass decline that researchers are now trying to reverse.

The Sea Grant funding also fits into a broader UNH research strategy that has been investing in coastal and marine assets for years. The new UNH EDGE NOAA mapping center in Durham, funded under a separate stream, gives researchers and community members access to high-resolution coastal mapping data that complements the work Sea Grant is funding. The same institutional muscle that helps UNH attract those federal partnerships keeps the state’s marine research community small but durable.

That durability is showing up in other research areas as well. Our coverage of UNH space-related research, including Mars water and rocket fuel work, is a reminder that the university is anchoring a research economy that extends well beyond the Seacoast. The marine work is part of the same flywheel.

What the funding does not do

The $1.2 million in Sea Grant research funding is not, by itself, going to solve PFAS contamination in Great Bay, restore eelgrass meadows to their historical extent, or build a domestic nori industry. The funding is a down payment on six specific questions that need answering before larger investments can be made intelligently. That is the way Sea Grant has always worked. It funds the science that informs the policy that drives the bigger spending.

NH Sea Grant has signaled that the next biennial Request for Proposals, expected to open in late fall 2026 for the 2028 to 2029 cycle, will encourage more aquaculture-focused research. That is a notable shift. Aquaculture is one of the few growth industries the New Hampshire Seacoast has, and the Sea Grant program has decided to point its research dollars in the direction where the economic upside is most concentrated.

For oyster farmers, fishermen, restaurant owners, and state regulators, the projects funded this cycle are a useful preview of what answers will be available in twelve to twenty-four months. For policymakers in Concord, the research provides a basis for the kind of evidence-driven decisions that are too rarely available when an estuary is in trouble. For the public, it is a reminder that even a small state with a small coastline can punch above its weight when its research dollars are aimed carefully.

What to watch through 2028

NH Sea Grant typically convenes an annual research symposium where investigators present preliminary findings. That symposium is one of the best places to track the projects funded in this cycle. Industry partners, state agency staff, and academic peers attend, and the dialogue often shapes how the projects evolve.

For now, the headline is that New Hampshire has secured a meaningful slice of NOAA-aligned marine research funding at a moment when many states are competing for the same dollars. The state’s research infrastructure, anchored by UNH and supported by Dartmouth, the Conservation Law Foundation, the Great Bay National Estuarine Research Reserve, and a network of working watermen, has earned that slice. The next two years will test whether the funded projects deliver answers that are useful enough to justify the next round of investment.

Given New Hampshire’s track record on Sea Grant science, the bet is a reasonable one. The Granite State is small. Its coastline is small. Its research community is small. The questions it is answering, however, are exactly the kind that translate into bigger industries, better regulation, and the kind of working waterfront the state’s residents and visitors want to see preserved.

What is NH Sea Grant and how is it funded?

NH Sea Grant is a federal-state partnership program based at the University of New Hampshire that funds coastal and marine research, extension, and education in the Granite State. It is part of the National Sea Grant College Program administered by NOAA, with non-federal matching funds typically required at 50 percent per project. National Sea Grant funding was set at $80 million in fiscal year 2026, with an additional $14 million for Sea Grant aquaculture.

What projects did NH Sea Grant fund for the 2026 to 2027 cycle?

The current funded portfolio includes PFAS bioaccumulation in marine food webs led by Celia Chen at Dartmouth, the Lumpfish Mapping Project led by Elizabeth Fairchild at UNH, eelgrass dynamics in Great Bay Estuary, longline nori production for seaweed aquaculture, improved Vibrio management tools for oyster aquaculture led by Cheryl Whistler at UNH, and temporal dynamics of phytoplankton populations in coastal New Hampshire.

Why does PFAS research in Great Bay matter for New Hampshire residents?

PFAS, a class of synthetic chemicals that resist environmental breakdown, have already been documented in New Hampshire drinking water and surface water. The Sea Grant-funded Dartmouth project will measure how PFAS accumulates in marine wildlife and transfers through the food web in a New England estuary. The findings will inform whether eating local seafood from places like Great Bay carries a measurable exposure risk and how state regulators should set advisories.

How does Vibrio research connect to New Hampshire oyster farmers and consumers?

Vibrio bacteria, particularly the ST36 strain, can sicken consumers who eat raw shellfish, and outbreaks have triggered closures and recalls in New England. The funded UNH project investigates how the bacteria are introduced through oyster seed transport, tests mitigation strategies including salt relay, and improves laboratory tests that distinguish dangerous strains from harmless ones. Better detection means more targeted closures rather than broad bed shutdowns that hurt the entire industry.

When does the next NH Sea Grant Request for Proposals open?

NH Sea Grant operates on a biennial cycle. The next major Request for Proposals, for the 2028 to 2029 funding cycle, is expected to open in late fall 2026, with pre-proposals due in winter 2027 and full proposals due in spring 2027. The program has signaled it will continue to encourage aquaculture-focused research alongside its traditional coastal and marine ecosystem priorities.
