The huge blob of seaweed headed for Florida has shrunk by 75%

July 12, 2023 — Florida vacations are back on, sans stinky seaweed.

The record-breaking mass of stinky seaweed that began appearing on Florida’s iconic beaches this spring, known as the Great Atlantic Sargassum Seaweed Belt, shrunk in the Gulf of Mexico by 75% last month, according to scientists from the University of South Florida’s Optical Oceanography Lab.

The seaweed, which smells like rotten eggs and emits toxic gases when it comes ashore, proved a nuisance for Florida beachgoers in the spring – which is also the start of the Sunshine State’s tourist season. In April, the seaweed set a record, with scientists identifying 3 million tons of sargassum in the Caribbean Sea.

Giant belt of smelly seaweed will soon invade Gulf Coast shores

March 27, 2023 — A huge belt of sargassum, a seaweed that originates in the Sargasso Sea, is anticipated to wash up on shores in Florida, states bordering the Gulf of Mexico, and Caribbean islands this summer.

A report by the University of South Florida’s Optical Oceanography Lab determined that more than 24 million metric tons of sargassum has collected in the Atlantic as of June 2022, one of the largest amounts in history. USA today reports visitors to Florida, Caribbean, and the Gulf of Mexico might encounter the sargassum as massive amounts of smelly, brown seaweed washed ashore.

Bed-scale impact and recovery of a commercially important intertidal seaweed

February 17, 2023 — A study led by the University of Maine captured how entire rockweed beds recover from harvest, and the practice has a smaller impact than previously thought.

Rockweed wields immense influence over its intertidal habitat. Its tangled branches form the backbone of a rich ecosystem that shelters and feeds an abundance of marine life. Everywhere rockweed grows, invertebrates, fish and fowl follow.

The marine alga has also been valued as a soil amendment for centuries, and more recently as crop biostimulants. The Maine Department of Marine Resources reports that commercial  has more than tripled over the past 20 years. Rockweed grows back following harvest, with biomass recovering faster than height. This change, combined with climbing harvest pressure, has led to concern regarding the practice. Harvesters, landowners, ecologists and community scientists want to understand how cutting and removing rockweed affects the ecosystem it creates.

Report assesses Alaska communities as locations for seaweed processing facilities

February 15, 2022 — The U.S. grows less than one-hundredth of one percent of the world’s $6 billion seaweed market, but Alaska has the goods to grow into a major contributor.

A new report assesses the pros and cons of six communities as locations for seaweed processing facilities to assist companies interested in operating in Alaska. It was compiled by McKinley Research Group for the Alaska Fisheries Development Foundation, which has played a central role in keeping Alaska seaweed in the resource development spotlight. Many believe the fledgling industry can top revenues of $100 million in little over a decade.

The six study communities were evaluated based on three categories: availability of seaweed supply, costs of doing business, and partnership opportunities.

So far, Kodiak leads all other regions in terms of supply, energy costs, water and sewer costs, resident labor, property taxes and shipping, with Craig and Ketchikan in the Prince of Wales Island region a close second.

MAINE: In the land of lobster, seaweed is finding its niche

December 7, 2021 — The annual Maine harvest of seaweed pales in comparison to lobster landings in pounds and value. Yet increasingly, lobstermen have joined other entrepreneurs in growing, harvesting and marketing Maine seaweed. Seen as another means of diversifying the state’s commercial fishing industry, it is turning into a multimillion-dollar industry and keeping in-shore fishermen busy during lobster’s off season. 

Rockweed, common along the Maine coast, accounts for about 95 percent of commercially harvested seaweed. It’s used for packing lobsters, as fertilizer and a nutritional additive for pet and livestock feed, and to extract alginate, used to thicken foods, cosmetics and even paint. 

But a smaller but growing market is for kelp, sugar kelp, dulse and Alaria, edible sea vegetables grown and harvested for nutritional and flavor supplements in a variety of foods. 

“People are recognizing its health benefits, its environmental benefits, and it tastes great,” Island Institute’s Sam Belknap said. The institute recently supported new aquaculturists, including seaweed growers, in a program for fishermen.

Kelp at the Crossroads: Should Seaweed Farming Be Better Regulated?

July 20, 2021 — On Vancouver Island, seaweed is abundant, diverse, useful, and symbolic. Indigenous peoples have used it for centuries for food preparation, fishing, and as a cultural and spiritual touchstone. On the island’s southwest coast, Dr. Louis Druehl started farming and researching kelp in the late 1970s and says he has dedicated his life to it “and loved every minute.” He mentored seaweed farmer Kristina Long, who now grows bull kelp over about 40 acres, and harvester Amanda Swinimer, who wades out into waist-deep water at low tide to carefully hand-cut blades of winged kelp in just the right spot to ensure regrowth.

These tiny operations barely create ripples within the vast coastal landscape, but kelp—here and elsewhere in North America—is at a crossroads.

In recent years, seaweed has been promoted around the globe as an overlooked, multifaceted climate solution: a sustainable food and biofuel source, a feed that reduces methane emissions from cattle, and a tool with the potential to absorb massive quantities of carbon from the atmosphere (although much more research is needed to determine how farms might actually contribute to sequestration). As a result, companies looking to capitalize on those promises are turning up in far-flung coastal communities with big plans.

Take Cascadia Seaweed. The company arrived on Vancouver Island soon after it was founded in 2019, and set a goal to farm 1,200 acres of the ocean there by 2025; its larger “stretch goal” is over 6,000 acre. In Alaska, Seagrove Kelp Co. has 127 acres in operation and 700 in the permitting phase. And in Maine, the continent’s seaweed-farming hub, Running Tide’s vision involves millions of biodegradable buoys attached to lines of kelp offshore.

Friend of the Sea Certifies SeaExpert for Sustainable Seaweed Production in the Azores

July 12, 2021 — The following was released by Friend of the Sea:

Friend of the Sea, the global certification standard for products and services that respect and protect the marine environment, has recognized seaExpert for sustainable seaweed production. Therefore, seaExpert can now display the Friend of the Sea label, certifying the engagement with sustainable marine practices.

SeaExpert, a company created in 2003 in the Azores archipelago, is a seaweed producer. It supplies clients with algae biomass for various uses, including cosmetics, supplements, livestock feed, and scientific research.

Seaweed, the generic name for different marine plants and algae, has been described as a game-changer. Filled with vitamins, minerals, proteins, and amino acids, it has immense potential, not only for human health but also for the planet. Including seaweed in cattle feed has the power to offset ruminant methane emissions, a gas that contributes to the greenhouse effect.

Friend of the Sea certifies companies that respect sustainable seaweed harvesting and farming. This standard aims to protect from overfishing wild seaweeds, which serve as a crop and as a habitat for hundreds of other ocean species.

The Azores, a Portuguese archipelago located in the North Atlantic Ocean, has a natural abundance of numerous algae species. SeaExpert identified the benefits of each specimen and developed a sustainable production process from harvesting to drying respecting the Friend of the Sea guidelines.

SeaExpert is licensed to harvest nine different species of algae, using sustainable techniques to have minimum impact on the marine ecosystem while supplying a high-quality product.The seaweed is harvested manually through scuba diving within seasons with the highest bioavailability rates.

The algae are dried in green houses or solar dryers, being monitored throughout the whole process. Once dried, the seaweeds are carefully weighed, packed, and stored.

“The protection of the ecosystem through sustainable practices is at the core of our company,” said a seaExpert’s spokesperson. “Achieving the Friend of the Sea certification represents a milestone as well as an encouragement to continue working.”

SeaExpert algae are an excellent component for the cosmetic industry. Scientific research has found that seaweed has hydrating and exfoliating benefits, as well as unique healing properties for people with acne, rosacea, and skin sensitivity.

“Seaweed production has boomed in the last years. Supporting companies involved in this emerging and promising sector to implement sustainable practices is crucial,” said Paolo Bray, Founder and Director of Friend of the Sea.

The core criteria of the Friend of the Sea sustainable seaweed certification are:

  • No impact on critical habitat.
  • Water monitoring.
  • Prohibition of using hazardous substances.
  • Energy management.
  • Social accountability.
  • Traceability.

‘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.

Northeast seaweed: Maine production continues to climb; doubling projected by 2025

January 29, 2021 — Seaweed continues to be a promising industry in coastal communities along the U.S. East and West coasts. Globally, the industry is valued at $12 billion, but commercial growth could be boosted by improved processing infrastructure and expanded markets.

While 95 percent of edible seaweed products in the United States are imported, there is a wild and growing cultivated harvest in the Northeast. A March 2020 study published by the Island Institute, titled “Edible Seaweed Market Analysis,” looked at growth potential in Maine’s edible seaweed markets over the next 15 years. The report found that production in Maine will grow about 12 to 15 percent annually over the next decade and is expected to more than double seaweed production by 2025.

Sugar kelp and alaria aquaculture are low-barrier and relatively affordable. They provide value-added opportunities for commercial fishermen and local economies, particularly where wild fisheries have declined. Maine Department of Maine Resources data on farm raised seaweed indicates that in 2018, 53,564 wet pounds valued at $37,897 were landed. In 2019, 280,612 wet pounds valued at $176,132 were landed.

Atlantic Sea Farms, a large commercial seaweed farm in Maine with 24 partner farmers, grew 30,000 pounds of seaweed in 2018. This year, the company planted enough for 800,000 pounds. The crop Atlantic Sea Farms cultivates ends up in products including fresh and frozen seaweed in pureed cubes and ready-to-eat and fermented products.
