Gulf of Maine sees first open-water ocean alkalinity enhancement field trial in US

August 29, 2025 — The U.S.’s first ocean alkalinity enhancement (OAE) field trial in federal waters took place on Aug. 13, with the dispersal of 16,500 gallons of sodium hydroxide into the Gulf of Maine. Led by a team of Woods Hole Oceanographic Institute (WHOI) scientists, this milestone represents the culmination of three years of planning, which for the last year has included a steady stream of feedback (including some unvarnished pushback) from the fishing industry.

I joined the field trial as a fishing industry observer, and this is my report to the fleet.

Fishing industry involvement in project planning

Ocean alkalinity enhancement was an enigmatic term to the New England fishermen who heard it for the first time in summer 2024, when the EPA opened a public comment period for input on a permit WHOI’s LOC-NESS (Locking Away Carbon in the Northeast Shelf and Slope) project.

“We don’t have a lot of tolerance for your curiosity right now,” and “The ocean’s not a lab rat,” were some of the comments made by anxious fishermen during the first informational meetings hosted by the WHOI team.

In the year since that first exposure, fishermen and their representatives have attended numerous meetings with the LOC-NESS team at port meetings, trade shows, and New England Fisheries Management Council meetings. As a result of fishermen’s input, the scientists changed the planned location of the project and lined up federal funding (later retracted) to test the effects of sodium hydroxide on the larval and egg stages of commercially important species like lobster and herring.

When the time came to perform the field trial, it seemed appropriate to ask if a fisherman could witness the event as an observer, so I asked if I could tag along. They were happy to oblige, and even set aside a tie-up stipend so I wouldn’t lose income due to time away from my fishing job.

Cape Cod scientists want to dump 60,000+ gallons of sodium hydroxide into ocean in climate change experiment

July 16, 2024 — Environmentalists and fishermen are pushing back against a plan from a group of scientists who want to dump more than 60,000 gallons of sodium hydroxide, more commonly known as lye, into the ocean off Cape Cod to gain an understanding of how to slow climate change.

Scientists from Woods Hole Oceanographic Institute in Falmouth are seeking a federal permit for their project, which would start sometime this summer with a field trial program that would disperse roughly 6,600 gallons 10 miles south of Martha’s Vineyard.

Woods Hole says there are two central goals to its so-called LOC-NESS project, short for “Locking away Ocean Carbon in the Northeast Shelf and Slope.”

The first is to “understand potential environmental impacts of using ocean alkalinity enhancement to remove carbon dioxide from the atmosphere.” The other is to “verify and report the amount of carbon dioxide this method might realistically remove if deployed at scale.”

“While emission reductions are key to minimizing human impact on Earth’s climate, it has become clear in recent years that drastic emission reductions must be supplemented by efforts to actively remove existing carbon dioxide from the atmosphere,” Woods Hole scientists wrote in their application to the Environmental Protection Agency.

Environmentalists and fishermen are not taking kindly to the proposed experiment which would continue next summer at a more drastic scale of roughly 60,000 gallons in the waters northeast of Provincetown, in the Gulf of Maine.

‘Great news’: 17 North Atlantic right whale calves spotted so far this season

February 6, 2024 — Marine wildlife officials on Monday shared promising news about the number of North Atlantic right whales born this season, as they continue to monitor the number of whales being injured or killed by entanglement and vessel strikes at sea.

The number of North Atlantic right whales born this season has already surpassed that of last year, with 17 new calves spotted with their mothers along the coast from Florida to South Carolina, according to the Woods Hole Oceanographic Institute on Cape Cod.

“While this is great news, the North Atlantic right whale population is still dwindling,” Woods Hole Oceanographic Institute officials said in a statement.

Spencer Fullerton Baird: Founder of the Woods Hole Laboratory and Fisheries Science

June 18, 2021 — The following was released by NOAA Fisheries:

Spencer Fullerton Baird was born in Reading, Pennsylvania in 1823. Time spent as a child exploring the countryside with his brother fueled his passion for natural history. In 1838 he met John James Audubon, who gave him part of his bird collection, and encouraged young Baird’s interest in ornithology and collecting specimens.

He attended Dickinson College, receiving his bachelor’s degree in 1840. Baird then enrolled in the College of Physicians and Surgeons in New York for a year, but decided he was not cut out for medical practice. He returned to Carlisle, Pennsylvania to continue his studies at Dickinson College. He received a master’s degree in 1843 and an honorary doctor of physical science degree in 1856

Baird was offered a teaching position at the college in 1845 as a professor of natural history. Popular with students for taking them into the field to study nature, he became chair of both the natural history and chemistry departments in 1848. He also served as librarian and curator of the college’s natural history collections.

Massachusetts waters remain closed to lobstermen

May 6, 2021 — The state Division of Marine Fisheries is reminding lobstermen and other trap fishermen that state waters north and east of Cape Cod remain closed to all commercial harvesting because of the continued presence of North Atlantic right whales.

DMF and the Provincetown Center for Coastal Studies continue to fly aerial survey flights to gauge the scale of right whale presence in state waters as the imperiled stock continues its northward feeding migration.

The agency said its most recent flight, on April 28, 2021, observed 86 right whales in the waters of northern Cape Cod Bay, southern Massachusetts Bay, and Stellwagen Bank, a fishing ground located about 15 miles southeast of Gloucester to about six miles north of Provincetown.

“Additional surveillance flights are anticipated to occur over the next several days,” DMF stated. “DMF will reevaluate the status of this closure based on the presence or absence of whales. Should observational data demonstrate right whales have migrated out of Massachusetts waters, DMF may lift the trap gear closure prior to May 15.”

Also, the Woods Hole Oceanographic Institute’s Slocum underwater glider on Sunday acoustically detected the presence of North Atlantic right whales north of Cape Cod and NOAA Fisheries on Monday instituted a voluntary right whale slow zone north of Cape Cod until May 17.

Studies investigate marine heatwaves, shifting ocean currents

September 22, 2020 — In a paper published September 17 in the Journal of Climate, WHOI oceanographers and collaborators at the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany use a new model to understand how ocean processes affect marine heatwaves at depth off the west coast of Australia. Known as “Ningaloo Niño,” these extreme warming events have caused mass die-offs of marine organisms, coral bleaching, and potentially permanent ecosystem shifts, all of which impact fisheries and the economies that depend on them.

“This area is a hotspot for increasing temperature and extreme events, with drastic impacts on regional marine species,” said lead author Svenja Ryan. “It’s important to understand where in the water column temperature and salinity changes are happening so you can determine how the ecosystem will be impacted.”

For the first time in the Southern Indian Ocean, Ryan and her co-authors, WHOI physical oceanographers Caroline Ummenhofer and Glen Gawarkiewicz, showed that the effects of marine heatwaves extend to 300 meters or more below the surface along the entire west coast of Australia. They found that during La Niña years, the southward-flowing Leeuwin Current becomes stronger and is associated with warm temperature anomalies at greater depths. These conditions were observed during the 2011 marine heatwave that led to the first-recorded coral bleaching at Ningaloo Reef, a World Heritage site, and extensive loss of a nearby kelp forest. During El Niño periods, the temperature and salinity anomalies associated with marine heatwaves are limited to the ocean surface, showing that complex ocean processes play an important role in the depth-extent of extreme events.

Ryan and her colleagues are using a similar modeling approach to study marine heatwaves in the Northwest Atlantic. “The challenge, wherever you go, is that marine heatwaves have so many drivers,” Ryan said. “Understanding different types of events and their associated depth structure is crucial for regional impact assessment and adaptation strategies, as well as for predicting potential changes in a future climate.”
