OSU researcher leads NOAA-funded project to study West Coast response to ocean acidification

March 4, 2021 — The following was released by Oregon State University:

An Oregon State University researcher is part of a new federally supported project investigating how communities along the West Coast are adapting to ocean acidification, with the goal of determining what they need to be more resilient.

Ana K. Spalding, an assistant professor of marine and coastal policy in OSU’s College of Liberal Arts, is leading a team looking into how shellfish industry participants in several towns along the Oregon and California coasts are responding to ocean acidification and where gaps in policy or resources have left them vulnerable.

The $1 million, three-year interdisciplinary project is funded by the National Oceanic and Atmospheric Administration (NOAA) through its Ocean Acidification Program. At OSU, Spalding is working with Erika Wolters, assistant professor of public policy, and Master of Public Policy students Victoria Moreno, Emily Griffith and Ryan Hasert.

“The goal of this project is to better align policy responses with the immediate and very local needs of shellfish-reliant communities,” Spalding said. “This is both understanding that vulnerability and proactively thinking, ‘What can we do to respond to better support members of the shellfish industry and their needs?’”

Ocean acidification and its impact on shellfish first became a major concern for West Coast farmers after a 2007 mass oyster larvae die-off at the Whiskey Creek Shellfish Hatchery in Netarts Bay, Oregon. OSU scientists definitively linked that die-off to increased carbon dioxide in the water in a 2012 study.

Small-scale fishermen turn to apps and AI to tackle climate change

March 2, 2021 — From weather predicting apps to using artificial intelligence to monitor the fish they catch, small-scale fishermen and coastal communities are increasingly turning to digital tools to help them be more sustainable and tackle climate change.

Overfishing and illegal fishing by commercial vessels inflict significant damage on fisheries and the environment, and take food and jobs from millions of people in coastal communities who rely on fishing, environmental groups say.

In addition, climate change affects on small-scale fishermen – who account for about 90% of the world’s capture fishermen and fish workers – include fish moving to new areas in search of cooler waters or if their habitat is destroyed, rising sea levels, and an increase in the number of storms.

Launched in January by nonprofit Environmental Defense Fund (EDF), the Small-Scale Fisheries Resource and Collaboration Hub (SSF Hub) is a multilingual website that aims to bring together fishermen, their communities and advocacy groups to connect, share ideas and find solutions to the problems they face.

Help make fisheries, aquaculture, and protected resources more resilient to climate change

March 2, 2021 — The following was released by NOAA Fisheries:

Agency announces 30-day comment period to collect information in response to Section 216(c) of the Executive Order on tackling the climate crisis.

NOAA is launching an agency-wide effort to gather initial public input on Section 216(c) of the Executive Order on Tackling the Climate Crisis at Home and Abroad. This section directs NOAA to collect recommendations on how to make fisheries, including aquaculture, and protected resources more resilient to climate change. This includes changes in management and conservation measures and improvements in science, monitoring, and cooperative research. We invite your input on how best to achieve these objectives. Submit your comments by April 2, 2021 to OceanResources.Climate@noaa.gov.

The input will inform NOAA’s implementation of our relevant authorities and our work with federal agencies, state and tribal governments, and relevant stakeholders and constituents to ensure more resilient fisheries and protected resources due to climate change.

Research has shown that fisheries, protected resources, and their habitats and ecosystems are being affected by climate change. Climate-related changes in ocean ecosystems such as warming oceans, increasing acidification, and rising seas can affect the distribution and abundance of marine species. These changes also impact the people and communities that depend on them. At NOAA, we work with partners to understand and respond to changing climate and ocean conditions to help minimize impacts, adapt to changes, and ensure that future generations can enjoy the benefits of healthy marine ecosystems.

Beyond this 30-day public comment period, we will continue to gather input throughout 2021 through meetings, public listening sessions, and other means. Information gathered after the initial deadline for comments will still be collected and considered.

In the Aleutians, climate change and ocean acidification impacts add to legacies of past exploitation

March 2, 2021 — In the waters around the Aleutian Islands, the 1,200-mile chain that arcs across the southern edge of the Bering Sea from Alaska to Kamchatka, modern climate change has layered atop a centuries-old legacy of human assaults to send combined impacts cascading through the marine ecosystem.

Evidence is in the once-colorful corals that have nurtured schools of fish supporting some of the world’s largest commercial seafood harvests. Under the clear waters is a pale world that signals a habitat in a tailspin.

The pale-pink scene shows the slow death of cold-water coral reefs that used to be buffered by the kelp, said Doug Rasher, a marine ecologist with the Maine-based Bigelow Laboratory for Ocean Science. “We’re passing the tipping point where these reefs have persisted and been able to survive,” said Rasher, who led a study of the coral ecosystem’s downward spiral.

The reefs are dying because they are being attacked by an exploding population of sea urchins. Having mowed down the surrounding kelp forest, the urchins are consuming the algae that the reefs produce to build their structures. The urchin population is booming because the sea otters that used to eat them have disappeared.

Climate change also weakens the corals. Warmer waters make the urchins grow faster, requiring them to eat more. Rasher’s study examined the algae’s microscopic growth layers and found that urchin foraging increased by up to 60 percent since preindustrial times.

Adding to the assault is ocean acidification, to which the Bering Sea is especially vulnerable. The shallow Bering, with its relatively cold waters, abundant sea life and wide seasonal fluctuations, is naturally primed to hold carbon. And carbon emitted by fossil-fuel burning is absorbed from the atmosphere into the water, lowering pH levels and threatening calcium-building life forms — not just the coral reefs, but shellfish such as crabs, as well the tiny creatures such as pteropods that make up the diet of fish like salmon.

‘Run The Oil Industry In Reverse’: Fighting Climate Change By Farming Kelp

March 1, 2021 — In the race to stall or even reverse global warming, new efforts are in the works to pull carbon dioxide out of the air and put it somewhere safe.

One startup in Maine has a vision that is drawing attention from scientists and venture capitalists alike: to bury massive amounts of seaweed at the bottom of the ocean, where it will lock away carbon for thousands of years.

The company is called Running Tide Technologies, and it’s prototyping the concept this winter. On a recent day in the Gulf of Maine, boat captain Rob Odlin says the task itself isn’t much different from any other in his seafaring career, whether chasing tuna or harvesting lobster.

“We’re just fishing for carbon now, and kelp’s the net,” he says.

Running Tide CEO Marty Odlin — the boat captain’s nephew — comes from a long line of Maine fishermen, and once imagined he would continue the tradition. But he watched as the warming climate drove major shifts in fish populations, while regulators put a lid on how much could be taken from the sea.

Scientists see stronger evidence of slowing Atlantic Ocean circulation, an ‘Achilles’ heel’ of the climate

February 26, 2021 — A growing body of evidence suggests that a massive change is underway in the sensitive circulation system of the Atlantic Ocean, a group of scientists said Thursday.

The Atlantic meridional overturning circulation (AMOC), a system of currents that includes the Florida Current and the Gulf Stream, is now “in its weakest state in over a millennium,” these experts say. This has implications for everything from the climate of Europe to the rates of sea-level rise along the U.S. East Coast.

Although evidence of the system’s weakening has been published before, the new research cites 11 sources of “proxy” evidence of the circulation’s strength, including clues hidden in seafloor mud as well as patterns of ocean temperatures. The enormous flow has been directly measured only since 2004, too short a period to definitively establish a trend, which makes these indirect measures critical for understanding its behavior.

The new research applies a statistical analysis to show that those measures are in sync and that nine out of 11 show a clear trend.

Prior research had suggested that the AMOC was at its weakest point in a millennium or more, and suggested a roughly 15 percent weakening since about 1950. But when it comes to the latest evidence, “I think it just makes this conclusion considerably stronger,” said Stefan Rahmstorf, an author of the research and an oceanographer with the Potsdam Institute for Climate Impact Research in Germany.

The study was published in Nature Geoscience by scientists from the Potsdam Institute, Ireland’s Maynooth University and University College London.

The AMOC is driven by two vital components of ocean water: temperature and salt. In the North Atlantic, warm, salty water flows northward off the U.S. coastline, carrying heat from the tropics. But as it reaches the middle latitudes, it cools, and around Greenland, the cooling and the saltiness create enough density that the water begins to sink deep beneath the surface.

Why a net‑zero future depends on the ocean’s ability to absorb carbon

February 26, 2021 — Most of us growing up along Canada’s East Coast never worried about hurricane season. Except for those working at sea, we viewed hurricanes as extreme events in remote tropical regions, seen only through blurred footage of flailing palm trees on the six o’clock news.

Today, a warming ocean spins hurricanes faster, makes them wetter and drives them towards Atlantic Canada and even further inland. Hurricanes, winter storms and rising sea levels will continue to worsen unless we slow climate change.

The lifeblood of coastal economies and societies has always been the connection between land and sea, and that’s become more evident with climate change. But this isn’t just a coastal story anymore.

The oceans moderate the world’s climate through the absorption of heat and carbon. And just how much carbon the ocean will continue to absorb for us remains an open question. Whatever we do, it must be grounded in our growing wisdom of the deep connections between life on land and in the sea.

As Canada commits to a net-zero future and plans its post-COVID economic recovery, innovations and investments could backfire if they reduce the ocean’s ability to absorb our excesses.

REPORT: CLIMATE CHANGE A MAJOR THREAT TO RECREATIONAL FISHING

February 24, 2021 — A new report by fly fishing industry leaders brings to light what scientists have long known: that fishing is suffering from the effects of climate change—and offers solutions.

The American Fly Fishing Trade Association and its nonprofit AFFTA Fisheries Fund released the report last week, which acknowledges, “Climate change is significantly affecting ocean ecosystems, the abundance and distribution of fish, and the nature of saltwater fishing.”

AFFTA sees the effects of climate change and overfishing as principal threats to fisheries that the fly-fishing industry has long fought to address. This blue-ribbon report offers a systematic approach to strengthen marine fisheries conservation and management, support recreational fisheries, and lead to more abundant marine fisheries in all U.S. ocean waters.

Though the report looks at these issues on a national scale, it offers many recommendations that apply to the Chesapeake Bay and its tributaries, from warming of upland coldwater brook trout streams to effects on oyster shells and loss of shoreline habitats. One particularly applicable example is the report’s commitment to work with coastal states to increase the size and distribution of seagrass beds, by improving water quality and planting grasses. It notes that coastal ecosystems like marshes and grassbeds are capable of absorbing carbon at rates up to four times those of forests on land.

As water temperatures rise, Rutgers scientists breed tougher shellfish

February 23, 2021 — Over the last half-century, global sea surface temperatures have been on the rise, but in the last decade they have increased at an accelerated rate.

New Jersey’s coastal waters, both along the Atlantic Coast and Delaware Bay, have been no exception. More alarming, recent research indicates that sea surface temperatures in the Northeast are warming two to three times faster than the global average. For instance, in 2012, water temperatures in the Mid-Atlantic reached the highest levels ever seen in over 150 years of recorded observations.

This rapid increase in water temperature is already influencing New Jersey’s marine species. Breeding habits, ranges and growth rates are adjusting as the environment in which they have evolved to thrive has changed at an unnatural pace. For the commercial fishermen and women whose livelihoods depend on the state’s fishery, particularly those who are only just beginning to experiment with shellfish aquaculture, warmer waters mean higher operational risk.

A new study from the Rutgers University Haskin Shellfish Research Laboratory, which has been monitoring New Jersey’s shellfish stocks for more than a century, is working to combat the impacts of climate change by selectively breeding bay scallops and surf clams that can grow faster and tolerate higher water temperatures.
