April 12, 2021 — It is true that my research program receives funding from the fishing industry. Industry funding makes up about 22% of my total funding, while I receive similar amounts from environmental foundations, Universities, and private individuals unassociated with the fishing industry. In addition, I receive funding from environmental NGOs, including over the years the National Resources Defense Council, The Nature Conservancy, Environmental Defense Fund, and the Pew Institute for Ocean Science.
Changes in Ocean Conditions and Human Activities Impacted the U.S. Northeast Shelf Marine Ecosystem in 2020
April 9, 2021 — The following was released by NOAA Fisheries:
Two new reports provide an updated picture of conditions supporting fisheries in the U.S. Northeast Shelf marine ecosystems. One report focuses on Georges Bank and the Gulf of Maine, two ocean regions off New England, and the other report focuses on the Mid-Atlantic Bight. These are the three major regions within the U.S. Northeast Continental Shelf Large Marine Ecosystem.
For the first time, the reports focus directly on how well we have achieved fishery management goals and the risks to achieving those goals posed by ecosystem changes and other human activities. Linkages between environmental conditions and managed species are also highlighted throughout the report. This focus ensures that scientists are providing ecosystem information in a form that the regional fishery management councils can use effectively.
Major findings in this year’s report include:
- Seafood production trends downward
- Recreational fishing effort is steady, but fewer anglers are taking for-hire trips
- Waters continue to warm and marine heat waves continue
- Less cold, fresh water is entering the Gulf of Maine
- The Gulf Stream is further north
- Chesapeake Bay’s warmer winter and cooler spring affected blue crab and striped bass<
- More fish species are moving to the north and east of their historic distribution, some into deeper water
The reports also cover new and rising factors, including offshore wind energy development and COVID-19 effects on fishery harvests and scientific data collection. There are more than 20 offshore wind development projects proposed for construction over the next decade in the Northeast. They have the potential to impact many parts of the ecosystem. With sufficient data, subsequent reports will further address these factors.
“Year of the quiet ocean”: Emerging ocean listening network will study seas uniquely quieted by COVID-19
April 8, 2021 — The following was released by the International Science Council:
Travel and economic slowdowns due to the COVID-19 pandemic combined to put the brakes on shipping, seafloor exploration, and many other human activities in the ocean, creating a unique moment to begin a time-series study of the impacts of sound on marine life.
A community of scientists has identified more than 200 non-military ocean hydrophones worldwide and hopes to make the most of the unprecedented opportunity to pool their recorded data into the 2020 quiet ocean assessment and to help monitor the ocean soundscape long into the future. They aim for a total of 500 hydrophones capturing the signals of whales and other marine life while assessing the racket levels of human activity.
Combined with other sea life monitoring tools and methods such as animal tagging, the work will help reveal the extent to which noise in “the Anthropocene seas” impacts ocean species.
Sound travels far in the ocean, and a hydrophone can pick up low-frequency signals from hundreds, even thousands of kilometres away. The highest concentrations of non-military hydrophones are along the North American coasts — Atlantic, Pacific and Arctic — Hawaii, Europe, and Antarctica, with some scattered through the Asia-Pacific region.
For over a century, navies have used sound to reveal submarines and underwater mines and for other national security purposes. Marine animals likewise use sound and natural sonar to navigate and communicate across the ocean.
But the effects of human-generated ocean sounds on marine life remain poorly understood.
“Measuring variability and change in ambient, or background, ocean sound over time forms the basis for characterizing marine ‘soundscapes,'” says collaborator Peter L. Tyack, Professor of Marine Mammal Biology at the University of St Andrews, Scotland.
“Assessing the risks of underwater sound for marine life requires understanding what sound levels cause harmful effects and where in the ocean vulnerable animals may be exposed to sound exceeding these levels. Sparse, sporadic deployment of hydrophones and obstacles to integrating the measurements that are made have narrowly limited what we confidently know.”
In 2011, concerned experts began developing the International Quiet Ocean Experiment (IQOE), launched in 2015 with the International Quiet Ocean Experiment Science Plan. Among their goals: create a time series of measurements of ambient sound in many ocean locations to reveal variability and changes in intensity and other properties of sound at a range of frequencies.
The plan also included designating 2022 “the Year of the Quiet Ocean.”
Due to COVID-19, however, “the oceans are unlikely to be as quiet as during April 2020 for many decades to come,” says project originator Jesse Ausubel, Director of the Program for the Human Environment at The Rockefeller University.
“The COVID-19 pandemic provided an unanticipated event that reduced sound levels more than we dreamed possible based on voluntary sound reductions. IQOE will consider 2020 the Year of the Quiet Ocean and is focusing project resources to encourage study of changes in sound levels and effects on organisms that occurred in 2020, based on observations from hundreds of hydrophones deployed by the worldwide ocean acoustics community in 2019-2021.”
With IQOE encouragement, the number of civilian hydrophones operating in North America, Europe, and elsewhere for research and operational purposes has increased dramatically. With these, IQOE and the ocean sound research community can shed needed light on humans’ influences on marine life and ecosystems.
The existing hydrophone network covers shallow coastal and shelf areas most influenced by local changes in human activity. It also includes deep stations that can measure the effects of low-frequency sound sources over large open ocean areas.
Of the 231 non-military hydrophones identified to February 2021, several have agreed to their geographic coordinates and other metadata being shown on the IQOE website (https://www.iqoe.org/systems), with organizers hoping to attract many more contributors.
Of the hydrophones identified, most are in US and Canadian waters, with increasing numbers elsewhere, particularly in Europe. Meanwhile, more acoustic instrumentation and measurements are clearly needed across the Southern Hemisphere.
The researchers are working to create a global data repository with contributors using standardized methods, tools and depths to measure and document ocean soundscapes and effects on the distribution and behavior of vocalizing animals.
As part of the effort to create a global time-series, new software under development by a team of researchers across the country and led by the University of New Hampshire (MANTA) will soon help standardize ocean sound recording data from collaborators, facilitating its comparability, pooling and visualization (From April 8, the new MANTA software will be available at https://bit.ly/3cVNUox)
As well, an Open Portal to Underwater Sound (OPUS) is being tested at Alfred Wegener Institute in Bremerhaven, Germany, to promote the use of acoustic data collected worldwide, providing easy access to MANTA-processed data.
Meanwhile, scientists over the past decade have developed powerful methods to estimate the distribution and abundance of vocalizing animals using passive acoustic monitoring.
“Integrating data on animal behavior on soundscapes can reveal long-term effects of changes in ocean sound,” says Jennifer Miksis-Olds, Director of the Center for Acoustics Research and Education, University of New Hampshire.
The fledgling hydrophone network will continue contributing to the Global Ocean Observing System (GOOS), a worldwide collaboration of observing assets monitoring currents, temperature, sea level, chemical pollution, litter, and other concerns.
“To observe a return to normal conditions as the pandemic subsides, the intensive acoustic monitoring by many existing hydrophones must continue at least through 2021,” says Edward R. Urban Jr, IQOE Project Manager, of the Scientific Committee on Oceanic Research.
Comparable unintended opportunities for maritime study are rare and important in modern history. They include the start (1945) and stop (1980) of above-ground nuclear testing, creating traces of carbon and tritium the movements and decay of which have provided major insights into ocean physics, chemistry, and biology.
As well, the terrorist attacks in New York City and Arlington, Va., on 11 September 2001, caused the cancellation of hundreds of civilian airline flights allowing scientists to study the effects of jet contrails (or their absence) on weather patterns.
Those attacks also led to a shipping slowdown and ocean noise reduction, prompting biologists to study stress hormone levels in endangered North Atlantic right whales in the Bay of Fundy. With their 2001 data, research revealed higher September stress hormone levels over the next four years as the whales prepared to migrate to warmer southern waters where they calve, suggesting that the industrialized ocean causes chronic stress of animals.
Precious chance
Seldom has there been such a chance to collect quiet ocean data in the Anthropocene Seas. COVID-19 drastically decreased shipping, tourism and recreation, fishing and aquaculture, energy exploration and extraction, naval and coast guard exercises, offshore construction, and port and channel dredging.
Data graphed by JP Morgan reveals the impact of COVID in several categories of commercial activity. If true also of maritime activity as suspected, it suggests a relatively short-lived quiet ocean due to COVID — late March to mid-May, 2020.
Says Jesse Ausubel: “Let’s learn from the COVID pause to help achieve safer operations for shipping industries, offshore energy operators, navies, and other users of the ocean.”
“We are on the way to timely, reliable, easily understood maps of ocean soundscapes, including the exceptional period of April 2020 when the COVID virus gave marine animals a brief break from human clatter.”
The end of that break is clear from recent news, he notes, pointing to this from California in mid-March, for example: Port of Long Beach Sets 110-Year Record in February.
Concludes Mr. Ausubel: “We invite parties in a position to help to join this global effort on the variability and trends of ocean sound and the effects of sound on marine life. The shocking global effect of COVID-19 on human additions of noise to the oceans can spur maturation of regular monitoring of the soundscape of our seas.”

Seafood tech companies demonstrate a leap forward in freshness monitoring using sensors and blockchain
April 6, 2021 — The following was released by Seafood Analytics:
Sustainable seafood company Envisible is teaming up with Certified Quality Foods, Inc. (dba Seafood Analytics) to capture product quality data on Envisible’s blockchain-enabled Wholechain traceability system. The initiative is starting with sockeye salmon coming from Northline Seafoods in Bristol Bay, Alaska, demonstrating an innovative commitment to transparency in seafood supply chains.
Northline is capturing product quality metrics at the point of harvest using Seafood Analytics’ handheld Certified Quality Reader (CQR), which measures the salmon’s electrical properties. Electrical properties are measured at the cellular level and are related to degradation, heat abuse and quality. The resulting quality data is then seamlessly uploaded into Wholechain, which logs this and other supply chain data on Mastercard’s provenance blockchain from the source all the way to grocers nationwide under a private label brand available at over 12 regional stores.
While the entire line of Envisible’s Frozen Seafood launched in 2019 is fully traceable and sustainably sourced, Northline’s sockeye salmon is the first of its kind to take traceability a step further with transparent quality readings. In fact all three companies – Seafood Analytics, Envisible and Northline Seafoods – have been recognized for their leadership in sustainable seafood at the Fish 2.0 Global Innovation Forum held at Stanford University.
About Northline Seafoods. Northine Seafoods, which is Marine Stewardship Council (MSC) certified, has been lauded for innovations such as ultra-low freeze technology used on its floating processor directly on fishing grounds, and began utilizing the CQR method in 2019.

Home-Based Researchers Keep 10-Year Study Afloat During Pandemic
April 5, 2021 — The following was released by NOAA Fisheries:
Even without a pandemic, figuring out the number of eggs a fish will lay during its spawning season is a difficult task. While this information is important to fishery biologists, long-term data are scarce. That hampers researchers ability to answer a fundamental question important for fishery managers: What affects the ability of marine fish, and fish populations, to replace themselves in an open ocean? The pandemic made answering this question even more difficult—but our researchers persevered.
“Many marine fish produce hundreds of thousands to millions of eggs per female per year, the survival of which determines the future abundance of a population,” said Mark Wuenschel, a fish biologist at the Northeast Fisheries Science Center. Wuenschel is leading a long-term study on “fecundity”—a term for reproductive potential—in two commercial flatfish species, winter flounder and yellowtail flounder. “We had to have enough samples, and we had to work out the methodology to do it.”
Annual fecundity — in this case, measured by the number of eggs — varies and depends on the size, age, and condition of the female fish. Environmental variables, such as temperature and available prey, also affect the growth, condition, and reproduction of the females. Like many things in life, timing is everything. To study fecundity, female fish have to be collected at just the right time from the right locations, and in large numbers. Then, lots of eggs need to be counted.
Enter Emilee Tholke and Yvonna Press, both center biologists who work with Wuenschel. They were granted access to their lab one day a week under specific safety protocols. They prepared egg samples and captured images of the eggs using a high-resolution camera with a macro lens and a microscope. Images were stored on a flash drive or transferred to a shared network file.
Then, working from home, each analyzed the images and entered the results into a shared database. Working from home not only kept the egg counts going, but ensured that critical sampling would continue, and prevented a back-log of sample processing work. This year’s effort completes a 10-year time-series of sampling, image analysis, and fecundity estimates for winter and yellowtail flounders.
Overfishing of Atlantic cod likely did not cause genetic changes: study
April 5, 2021 — Overfishing likely did not cause the Atlantic cod, an iconic species, to evolve genetically and mature earlier, according to a study led by Rutgers University and the University of Oslo—the first of its kind—with major implications for ocean conservation.
“Evolution has been used in part as an excuse for why cod and other species have not recovered from overfishing,” said first author Malin L. Pinsky, an associate professor in the Department of Ecology, Evolution, and Natural Resources in the School of Environmental and Biological Sciences at Rutgers University-New Brunswick. “Our findings suggest instead that more attention to reducing fishing and addressing other environmental changes, including climate change, will be important for allowing recovery. We can’t use evolution as a scapegoat for avoiding the hard work that would allow cod to recover.”
The study, which focuses on Atlantic cod (Gadus morhua) off Newfoundland in Canada and off Norway, appears in the journal Proceedings of the National Academy of Sciences.
In the Northwest Atlantic Ocean, cod range from Greenland to Cape Hatteras, North Carolina. In U.S. waters, cod is most common on Georges Bank and in the western Gulf of Maine, but both fish stocks are overfished. Cod can reach 51 inches long, weigh up to 77 pounds and live more than 20 years. Early explorers named Cape Cod in Massachusetts for the species because it was so abundant off New England, according to the National Oceanic and Atmospheric Administration.
Research Finds Climate Change Impacts Young Cod in Alaska
April 2, 2021 — NOAA Fisheries highlighted a new study that indicates warming waters in Alaska are increasing the likelihood of prey mismatch and starvation for Pacific cod larvae.
The study was a collaboration between NOAA Fisheries scientists and partners to assess how temperatures impacted first feeding Pacific cod larvae in the Bering Sea and Gulf of Alaska through 1998-2019.
International study shows alternative seafood networks provided resiliency during pandemic
April 1, 2021 — Local alternative seafood networks (ASNs) in the United States and Canada, often considered niche segments, experienced unprecedented growth in the early months of the COVID-19 pandemic while the broader seafood system faltered, highlighting the need for greater functional diversity in supply chains, according to a new international study led by the University of Maine.
The spike in demand reflected a temporary relocalization phenomenon that can occur during periods of systemic shock—an inverse yet complementary relationship between global and local seafood systems that contributes to the resilience of regional food systems, according to the research team, which published its findings in Frontiers in Sustainable Food Systems.
The globalization of seafood has made food systems more vulnerable to systemic shocks, which can impact those dependent on seafood for sustenance and employment, according to the research team, led by Joshua Stoll, assistant professor of marine policy at the University of Maine.
Policy changes and greater investments in data collection and infrastructure are needed to support ASN development, increase functional diversity in supply chains, and bolster the resilience and sustainability of regional food systems and the global seafood trade, according to the researchers.
