Collaborating with Canadian Scientists on Marine Carbon Dioxide Removal Research

October 6, 2026 — I first met Dr. Helen Gurney-Smith in fall 2024, when Dr. Shannon Meseck and I drove just beyond the U.S.-Canada border to the St. Andrews Biological Station in New Brunswick. We went there to study larval sea scallop respiration when exposed to near-future temperature and pH. This past winter, Dr. Gurney-Smith’s research group drove south to visit us at the NOAA Fisheries Milford Lab in Connecticut. We studied how a proposed method of marine carbon dioxide sequestration may affect the single-celled phytoplankton community in the ocean.

This project was a part of a collaborative effort funded by the NOAA Ocean Acidification Program to engage early-career scientists from U.S. and Canadian fisheries agencies in ocean acidification research. Brady Quinn was the co-principal investigator on this project. Quinn, along with Dr. Gurney-Smith, and Erin Miller made up the Fisheries and Oceans Canada team, while Dr. Meseck, Genevieve Bernatchez, Lauren Witick, and I represented NOAA Fisheries.

Studying the Effects of Buffering Ocean Water with Olivine

Increasing carbon dioxide dissolved in the ocean causes ocean acidification, which is a concern for ecosystems. It’s especially harmful for marine life that build calcium carbonate shells, which can degrade in seawater with lower than normal pH. There are several proposed mechanisms to help keep the pH up in the ocean, including methods to increase alkalinity, effectively buffering seawater. One method is to add a naturally occurring mineral known as olivine to high-risk areas. As olivine dissolves in seawater, it breaks down into parts that can raise the pH of the water, making it less acidic. This works much like taking an antacid for an upset stomach.

When olivine breaks down it releases several elements phytoplankton need to grow, including the trace metals magnesium and iron, along with silica. Silica is an important nutrient for the growth of some phytoplankton, called diatoms. Diatoms are an excellent food for shellfish and other small marine grazers. Similar to plants, they can make oxygen from carbon dioxide through photosynthesis, making them an integral part of marine ecosystems. These diatoms use silica to create a glass-like cell wall, and it is possible that the release of extra silica from olivine could stimulate their growth.

Aerial Surveys: Monitoring Right Whales from Above

August 14, 2026 — This story is part two of a three-part series. Read about how we are listening for North Atlantic right whales with passive acoustics, monitoring them with aerial surveys, and using boats, drones, uncrewed surface vehicles and satellites to learn as much as we can about them and their habitat. In the Northeast, we work with many partners to track right whales, including mothers and calves, using advanced technology to help inform actions that reduce risks to the species.

Many North Atlantic right whales migrate thousands of miles to the Southeast and the Mid-Atlantic from mid-November to mid-April. Female right whales give birth in the shallow coastal waters of the Southeast during the winter months. The whales spend the rest of the year feeding in the plankton-rich waters off of the Northeast and Canada.

We take to the skies to monitor this journey. The Northeast Fisheries Science Center’s aerial survey team conducts right whale surveys aboard a NOAA Twin Otter Aircraft. The team has flown 325 hours monitoring whales since January 2026. In the spring, they monitored whales off of New England and the Mid-Atlantic. In June, they joined Fisheries and Oceans Canada (DFO) as part of a Joint Aerial Survey Team, flying out of Charlottetown, Prince Edward Island, Canada. There, they flew 50 hours monitoring aggregations of right whales in the Gulf of St. Lawrence.

Shark finning, endangered species found in high seas boardings

August 11, 2026 — Enforcement officers have finished their deployment with Operation North Pacific Guard, the annual multinational patrol that polices illegal, unreported, and unregulated fishing in international waters of the North Pacific.

Officers from NOAA’s Office of Law Enforcement patrolled more than 8,000 nautical miles aboard the Canadian Coast Guard ship Sir Wilfrid Laurier, sailing with fishery officers from Fisheries and Oceans Canada (DFO), the Canadian Coast Guard, the Royal Canadian Mounted Police, the U.S. Coast Guard and the Fisheries Agency of Japan. Working under authorities granted by international law, the crew conducted dozens of boardings and inspections of foreign fishing vessels and documented violations of conservation and management measures including shark finning, possession of endangered species and failure to accurately report catch, according to NOAA.

Suspected violations were referred confidentially to the flag states of the vessels involved and to the relevant regional fisheries management organizations for investigation. Under RFMO procedures, flag states handle the investigations and any penalties; sanctions can be reviewed by the RFMOs and, for the most serious cases, can include a complete ban on fishing.

“The dedication of our officers ensures that sustainable fishing practices are upheld on a global scale,” said Benjamin Cheeseman, assistant director of NOAA’s Office of Law Enforcement, Alaska Division. “Their work on the high seas directly protects the integrity of the oceans and the livelihoods of honest fishermen back home.”

NOAA did not release a violation count. DFO, which led the shipboard patrol, said in its own Aug. 6 announcement that the integrated crew aboard the Sir Wilfrid Laurier monitored several hundred fishing vessels, conducted 30 high-seas inspections and interacted with more than 500 crew members over roughly two months, turning up 52 potential violations. Those included shark finning and the use of prohibited gear to take sharks, misreporting of catch, bycatch and discards — including prohibited species — and multiple failures to use seabird protection measures while setting gear.

Endangered whale recently seen off Cape Cod may need rescue after entanglement

June 15, 2026 — A young right whale that was seen off Massachusetts two months ago may need to be rescued after it was observed in Canadian waters with fishing gear in its mouth.

Fisheries and Oceans Canada said that on June 8, aerial observers spotted an entangled North Atlantic right whale in the Gulf of St. Lawrence near Shippagan, New Brunswick. They said if the whale is spotted again and conditions allow, “efforts will be made to remove any gear from the animal.”

The New England Aquarium said that the unnamed 5-year-old male was seen gear-free in Cape Cod Bay on April 21.

Canada announces North Atlantic right whale protections for 2026

March 27, 2026 — Canada’s government has announced several measures to help protect highly endangered North Atlantic right whales in upcoming commercial fishing seasons, keeping some protections in place and adding a few new actions to help reduce entanglements and vessel strikes.

“The North Atlantic right whale is one of the most endangered animals on the planet, and we have a responsibility to act. Canada’s protocols are in place, and our whale-safe fishing gear pilots are showing real results. We can protect this whale and support our harvesters,” Canada Minister of Fisheries Joanne Thompson said in a release.

Catch limits for scallops on Georges Bank reduced due to increase in predator population

October 28, 2025 — One of Nova Scotia’s most lucrative seafood species is being attacked by natural predators on one of the most famous fishing grounds.

What remains to be seen is whether it’s a short-term occurrence or a sign of things to come.

A recently published stock assessment by Fisheries and Oceans Canada for sea scallops in Scallop Fishing Area (SFA) 27A on Georges Bank notes major changes in the amount of biomass and natural mortality rates. The changes were dramatic enough that DFO reduced the total allowable catch last December.

Fully recruited biomass decreased to 13,570 tonnes in 2024 from 31,095 tonnes in 2023 after fluctuating “within the healthy zone since the 2000s,” the science advisory report said. Fully recruited refers to commercial-size scallops.

Recruit biomass — the total mass of new scallops in the population — dropped by 72 per cent from 2023 to 2024.

The report said the “significant interannual changes” in stock condition for the SFA are likely driven by environmental variability.

“Research vessel survey data from Canada and the United States suggest that predator abundance, notably sea stars and crabs, has increased within the areas of known scallop distribution. Aggregations of predators in areas of high scallop density contribute to increases in natural mortality.”

Canadian Fisheries Minister Announces 2-Year Renewal of Discovery Island Fish Farm Leases

June 24, 2022 — Progress is being made to transition from open-net pen salmon aquaculture in British Columbia.

Joyce Murray, Minister of Fisheries, Oceans and the Canadian Coast Guard, announced on Wednesday that the Government of Canada is committed to transition from open-net pen salmon aquaculture in British Columbia’s coastal waters in a manner that “protects wild salmon, the environment and the economy.” As part of that commitment, the government agency is introducing draft framework for the transition. Fisheries and Oceans Canada (DFO) will be relying on input from the Government of British Columbia, First Nations, industry, local governments, stakeholders, and British Columbians to develop the final transition plan. Consultations will continue until early 2023, with the expectation that the final transition plan will be completed by spring 2023.

As the DFO works with partners and receives feedback, marine finfish aquaculture facilities outside of the Discovery islands will have a two-year renewal of licenses. These licenses will have stronger requirements for aquaculture facilities, including the implementation of standardized reporting requirements and sea lice management plans, as well as wild salmon monitoring. The DFO says that all of this will “improve the management of the salmon aquaculture industry and help protect wild salmon stocks and their habitat.”

Fishery Closures and the Ghosts of Past Mistakes

October 22, 2021 — David Christian, a 63-year-old gill-netter, first heard about the Pacific salmon fishery closures via cellphone while he was getting his 11-meter Grizzly King gill-netter ready to fish for salmon. The news spread quickly across the calm June waters off the west coast of Vancouver Island, British Columbia, as fishers jumped on the radio to figure out what had just happened.

The radio chatter was incessant as fishers wondered aloud where they’d be allowed to fish, if they would be out of business, and what the future would hold. “Everyone was freaking out because all of those questions were unanswered,” Christian says, adding this policy will likely end British Columbia’s commercial salmon industry.

Announced on June 29, the closures are part of the latest plan by Fisheries and Oceans Canada (DFO) to overhaul the Pacific salmon commercial industry in an attempt to save crashing salmon stocks. Pacific salmon harvests are down to just eight percent of their historical averages. The fishers were reacting to the Pacific Salmon Strategy Initiative (PSSI), a CAN $647.1-million plan covering everything from habitat restoration to financial aid for fishers. Its goal: save the salmon and shrink the size of the commercial industry built around them.

Under the PSSI, DFO plans to close 57 percent of the 138 Pacific salmon fisheries along the west coast of British Columbia and Yukon. Closures will help protect at-risk salmon stocks from ending up as by-catch, says Neil Davis, DFO acting regional director of fisheries management. Fishing for salmon in the ocean—unlike traditional practices where Indigenous communities fish in rivers—makes it practically impossible to separate at-risk stocks from healthy stocks.

Davis says closures will protect more than 50 salmon stocks, such as the interior Fraser River coho and Okanagan River chinook, which are being evaluated by the Committee on the Status of Endangered Wildlife in Canada for listing under the Species at Risk Act.

UFAWU-Unifor responds to DFO’s Pacific Salmon Strategy Initiative

June 10, 2021 — United Fisherman and Allied Workers Union – UNIFOR has responded with deep concerns to the same-day announcement by Fisheries and Oceans Canada (DFO) introduction of the Pacific Salmon Strategy Initiative (PSSI), on June 8.

The UFAWU-Unifor responded that it is deeply troubled by the dire state of the commercial salmon industry, albeit very appreciative that DFO is addressing the current plight.

The initiative “aims to curb historic declines in key Pacific salmon stock and rebuild species to a sustainable level,” the DFO stated in a media release. The PSSI is based on four key pillars: Conservation and stewardship; Enhanced hatchery production; harvest transformation; and integrated management and collaboration.

“It is crucial that steps are taken to save B.C. salmon,” the union stated.

“While it is evident that salmon are in a state of crisis, so are B.C.’s harvesters — DFO has a responsibility to both salmon fishermen and industry workers.”

Under the $647.1 million PSSI, the federal government committed to working in partnership with local organizations and groups in its development and delivery.

Regulatory approaches differ for burgeoning offshore aquaculture sector

April 5, 2021 — As offshore aquaculture becomes a more viable enterprise globally, a variety of regulatory approaches have emerged that reflect conflicting perspectives of the sector as either an economic opportunity or an environmental threat.

The governments of Canada and Denmark have both taken aggressive actions to curtail offshore aquaculture, with Denmark banning any new projects as of December 2020 and Canada adopting increasingly restrictive policies on net-pen aquaculture.
