Beneath the surface: what buoys reveal about ocean acidification

October 15, 2026 — What can a buoy tell us about ocean acidification? Quite a lot, especially when it has been collecting measurements for years.

In the California Current, a slow moving southward current that moves from British Columbia to Baja California, long-term observations help scientists track how ocean conditions change over hours, seasons, and years. Since natural phenomena like upwelling and El Niño rapidly alter water chemistry, continuous observations are vital for separating short-term fluctuations from broader ocean acidification trends.

Join Scripps Institution of Oceanography (Scripps) graduate student, Charles Lindsay, at sea as the recent Ocean Time-Series group, led by Uwe Send, deploy and maintain an ocean monitoring mooring off Southern California. In Anchored in the California Current: A Buoy’s View of Ocean Oscillations, readers are taken aboard a “day in the life” look at the work behind long-term ocean observations and the effort required to keep these instruments collecting data.

NOAA invests $45.7 million to improve ocean observing systems

October 9, 2026 — NOAA’s U.S. Integrated Ocean Observing System (IOOS®) Office announced today 11 new five-year cooperative agreements to support regional and national ocean observing. These agreements will enable U.S. IOOS regional associations to operate regional coastal observing systems (RCOSs) throughout U.S. waters, and will provide $45.7 million in funding for the first year.

Data collected from ocean observations:

  • Supports anglers, aquaculturists, shipping and logistics managers, and coastal communities in making sound economic and safety decisions;
  • Supports management and mitigation of coastal hazards, such as flooding and harmful algal blooms; and
  • Provides essential information for weather forecasting and national defense.

The regional associations are a fundamental part of the national observing system, and help ensure that the system is both effective and efficient. They are federally certified to collect and manage high-quality observing data, forming robust partnerships with local stakeholders and coastal communities. As the regional component of the nationwide U.S. IOOS network, regional associations meet local needs by using stakeholder feedback to guide the development of RCOSs while also integrating national priorities and requirements.

These cooperative agreements are awarded every five years through a competitive process and support the continued operation and modernization of our nation’s coastal, ocean and Great Lakes observing capabilities. Total awards include additional funding from other NOAA offices in the National Ocean Service, National Weather Service, NOAA Fisheries, NOAA Satellites and NOAA Research.

Mel Allen: Telling the stories of New England

August 25, 2026 — For more than 50 years, Mel Allen has made a career out of telling stories about those in New England.

He has written about fishermen and island communities, sardine packers and chefs, scientists counting fish aboard NOAA research vessels, and people whose livelihoods disappeared as fisheries and working waterfronts changed around them.

So when the former longtime editor of Yankee Magazine stood before a room filled with ocean scientists, researchers, and industry partners at the 2026 Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) Annual Meeting, he came with a message that was surprisingly simple.

Tell people a story.

“If you want people to care about something big, whether conflicts between nations, the dilemma of immigration, or our changing oceans, do not show the topic,” Allen said. “Show how people have been touched by the topic. That’s how we relate to each other.”

For NERACOOS, that message comes at an important moment.

NERACOOS helps coordinate sensors, models, data systems, and other technology used to track conditions across New England’s waters. Now, its work is expanding through the new National Science Foundation (NSF) Seafood Engine in New England, an initiative focused on supporting New England’s seafood industry.

The potentially 10-year initiative is designed to build an innovation network across the seafood supply chain, connecting work on the water with processing, distribution, and the consumer. Its focus includes environmental sensing and modeling, technology development, workforce training, and investment.

For commercial fishermen, that puts an industry accustomed to being on the receiving end of scientific data and management decisions closer to the center of a much broader effort to determine how New England seafood adapts to a changing ocean and economy.

But Allen’s keynote reminded everyone what all that technology and investment is ultimately intended to serve.

People.

Beyond Ocean Mapping: Using Uncrewed Vehicles to Advance Ocean Research

August 21, 2026 —  It’s January off of Nantucket Shoals. An uncrewed surface vehicle begins a series of carefully planned transects through Southern New England, collecting data day and night. There are no scientists onboard, but the 30-foot vessel is constantly measuring ocean currents, water temperature, salinity, weather and other ocean conditions. It’s also helping identify areas with high fish and plankton abundance. Every nautical mile traveled adds to a more complete picture of how marine ecosystems function.

These missions reflect NOAA’s growing use of uncrewed systems technology. Traditionally, these autonomous platforms have supported hydrographic surveys, nautical charting, and ocean mapping. But the benefits extend beyond creating better maps. Today, the same technologies are helping scientists answer complex ecological and oceanographic questions. They’re collecting critical, high-accuracy, and time-sensitive data across nearly every mission area.

“Over the last several years, we have been able to expand the applications for how uncrewed surface vehicles can help with various research related to stock, ecosystem, and protected species evaluations and assessments,” explains Dr. Conor McManus, marine development and advanced technology program lead for the Northeast Fisheries Science Center. “With each mission we conduct, we are learning more about the Northeast U.S. Shelf ecosystem, but also how we can better operationalize these technologies to meet our scientific or data needs.”

These technological advances are expanding where, when, and how our scientists collect ocean data. The results allow researchers to observe the ocean more continuously and in places that are difficult to sample with ships alone. These vehicles complement ship-based surveys—filling gaps in data that can arise from challenges like winter weather and limited ship availability.

This year, there were three uncrewed surface vehicle missions in the Northeast—two operated by Chance Maritime Technologies and one using DriX. They demonstrated how the benefits of uncrewed survey technology can answer many different scientific questions.

NOAA scientists set sail on landmark West Coast Ocean Acidification survey

July 21, 2026 — The following was released by the Pacific Marine Environmental Laboratory, National Oceanic and Atmospheric Administration:

On July 20, 2026, researchers embarked on the NOAA Ocean Acidification Program’s West Coast Ocean Acidification mission (WCOA 2026). Departing from San Diego aboard the University of Alaska, Fairbanks (R/V) Sikuliaq, the team will travel north to Washington, adding important new observations to NOAA’s long-term monitoring of ocean acidification and its impacts on marine resources.

WCOA 2026 will couple ocean chemistry, biology, and physics to build a more comprehensive view of how extreme events impact biogeochemistry and ecosystems.

“Results from past WCOA cruises have provided novel insights into acidification rates and impacts in coastal and estuary habitats that provide our nation with rich fish and shellfish resources,” said Dr. Simone Alin, Supervisory Oceanographer, NOAA/PMEL. Resource managers and harvesters can use this information to inform fisheries management decisions.

This intensive 30-day coastal research cruise aboard the 261-foot research vessel offers scientists a unique opportunity of sampling during an El Niño that is on track to become one of the strongest on record. El Niño brings warmer water and can alter upwelling and precipitation patterns in the region. Phytoplankton and zooplankton communities will follow these warmer waters, which impacts food webs and fisheries as seen during past marine heatwaves.

Two days after the Sikuliaq departs, the PMEL SeaTrac will head south from Washington to collect added coastal measurements during peak ocean acidification and hypoxia season and pick up any El Niño signal that may have made to the northern California Current System this summer. These OA cruises provide critical high-quality data for the U.S. Coastal Large Marine Ecosystems, and are essential for modeling and forecasting changes in ocean acidification and hypoxia to better prepare for future impacts to valued fisheries and ecosystems.

Led by researchers at the University of Washington’s Cooperative Institute for Climate, Ocean, & Ecosystem Studies and PMEL, researchers will collect high-quality ocean chemistry data, phytoplankton, zooplankton, and other observations. Scientists will also collect environmental DNA, which can reveal the diversity and abundance of ocean life in different ocean conditions.

Data collected during WCOA 2026 are essential for validating models and forecasts of ocean conditions like J-SCOPE. This short term (six to nine month) forecast is used for the California Current Integrated Ecosystem Assessment. High quality ocean carbon chemistry data is required to forecast the saturation state of calcium carbonate, the mineral building block used by shellfish like Dungeness crabs, clams, and oysters.

Other coordinated regular coastal fisheries surveys, including the California Cooperative Oceanic Fisheries Investigations (CalCOFI) enhance the impact of WCOA 2026. By conducting biological net tows at established stations, researchers will gain high-quality data on marine life.

Ultimately, the data collected through WCOA 2026 will serve as a foundational benchmark for monitoring, modeling and research in the region. These data will provide calibration information for sensor networks designed to fill measurement gaps between research cruises. With the potential for sampling to occur as ocean conditions change with El Niño, NOAA and our partners will be able to better understand how extreme conditions alter vital marine resources like Dungeness crabs, krill, plankton and other fisheries.

NSF awards $15M to launch New England Seafood Engine

July 15, 2026 — A new federally backed initiative aimed at strengthening the U.S. seafood industry is bringing $15 million to New England, with commercial fishermen expected to play a central role in developing new technologies for the sector.

The U.S. National Science Foundation (NSF) announced July 14 that the NSF Seafood Engine in New England has been selected for funding through the agency’s Regional Innovation Engines program. Led by the Portsmouth, N.H.-based Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS), the initiative brings together seafood industry leaders, researchers, government agencies and technology partners across Maine, Massachusetts, New Hampshire and Rhode Island, including the Cape Cod Commercial Fishermen’s Alliance.

According to the announcement, the project will receive $15 million over its first two years, with the potential to grow into a $160 million investment over the next decade as it builds a regional innovation hub focused on fisheries and aquaculture.

Will Maine lobster crash like cod? Only close ocean monitoring will tell

November 2, 2015 — There was a mix of news about the Gulf of Maine last week. First, there were dire warnings about the role of rising ocean temperatures in the demise of cod in the North Atlantic. Then came what sounded like good news — Maine has surpassed Massachusetts to become the state with the second most lucrative seafood landings in the country. Finally, on Friday, federal regulators announced they would close the Gulf of Maine herring fishery this month.

All of these stories are interrelated and point to the need for much more research to gain better understanding about what is happening in the Atlantic Ocean and why. With better knowledge about how changing ocean conditions affect different species, regulators can more effectively target rules to protect them and the fishermen who make a living catching them.

The virtual disappearance of cod from the waters off New England is not news. But a new report, published in the journal Science, concludes that rising ocean temperatures played a much larger role in the decline than initially thought. The study’s lead author, Andrew Pershing, is a scientist with the Gulf of Maine Research Institute in Portland.

In the simplest sense, regulators decide how many tons of a species can be taken from the ocean based on assessments of that species’ population. The problem with cod management, Pershing’s report concludes, is that regulators didn’t fully grasp the severity of the ocean temperature increase and what it meant for the legendary groundfish. As a result, regulators allowed fishermen to catch too many cod.

“Failure to recognize the impact of warming on cod contributed to overfishing,” the report said. “Recovery of this fishery depends on sound management, but the size of the stock depends on future temperature conditions. The experience in the Gulf of Maine highlights the need to incorporate environmental factors into resource management.”

This is especially true in the gulf, which is warming faster than 99.9 percent of the world’s oceans. Most troubling, beginning in 2004, the rate of warming in the Gulf of Maine increased more than seven-fold, the report says. Because of this rapid warming, regulatory limits on cod fishing didn’t work because cod did not reproduce and grow as expected.

This isn’t an academic problem. As the cod population declined, regulators imposed quotas that allowed fishermen to catch less. When the population didn’t rebound, regulators tightened the quotas, adding to the economic hardship for fishing communities.
