Loss of ocean monitoring could create fisheries blind spot

June 8, 2026 — The Alaska Marine Community Coalition is raising concerns over plans to dismantle much of the federal Ocean Observatories Initiative (OOI), arguing that the loss of long-term ocean monitoring could reduce critical information used to understand changing conditions in Alaska’s fisheries.

In a recent statement, the coalition said the National Science Foundation plans to remove in-water equipment from four of the five OOI sites over the next 15 months, including Ocean Station Papa in the Gulf of Alaska, located roughly 620 miles offshore. The network has collected continuous oceanographic data since 2016, while Station Papa itself has served as one of the North Pacific’s longest-running ocean monitoring locations.

The coalition said the station provides information on deep-water temperatures, ocean chemistry, currents and biological conditions that help scientists track changes affecting species including salmon, halibut, crab and pollock.

Congress should heed the Pacific Ocean’s super El Niño warning

June 4, 2026 — Listen up, lawmakers: The Pacific Ocean is trying to send you a message about the federal budget.

About once every two to seven years, the Pacific trade winds weaken and water temperatures shift, causing profound impacts for the global climate. The phenomenon is called “El Niño.” The latest data from the world’s largest ocean are telling us that a “super El Niño: will likely develop this year, possibly among the most powerful such events ever recorded.

The possibility of a strong El Niño should serve as a wake-up call to Congress. Lawmakers are now considering the Trump administration’s proposed budget cuts to the National Oceanic and Atmospheric Administration — the agency known by the acronym NOAA (pronounced “Noah”), which serves as America’s eyes and ears on the world of weather.

If lawmakers choose to hollow out and treat this agency as a set of separable parts, the consequences for American communities and for the national economy will be dire.

Lawmakers in Washington must fully fund the agency’s work to monitor global weather patterns and keep Americans informed. By doing so, they will protect us all.

In Kachemak Bay, Kotzebue and beyond, Alaskans are on the lookout for harmful algae blooms

June 3, 2026 — Algae is vital to a healthy marine system, and most of the hundreds of varieties in Alaska’s waters are beneficial or benign.

But the handful that are harmful are, like other algae, proliferating in warmer conditions and releasing or threatening to release toxins that can sicken people and wildlife and, in the worst cases, cause deaths.

The best-known type of algae that poses risks to people, mammals and birds in Alaska is called Alexandrium. The toxins it produces cause paralytic shellfish poisoning; they block the delivery of sodium to cells, thus interfering with or shutting down nerves essential to bodily functions.

The most potent Alexandrium toxin is saxitoxin, but there are related toxins produced by the same algae called gonyautoxins, or GTX. Some GTX varieties, including one detected in tomcod harvested in December by Nome-Beltz High School students in a yearslong science project, are nearly as toxic as saxitoxin. For simplicity’s sake, testing for paralytic toxins often lumps measurements of saxitoxin and GTX compounds together as “saxitoxin equivalent,” said Thomas Farrugia, coordinator of the Alaska Harmful Algal Bloom network.

ALASKA: Algal toxins emerge as a new concern in Alaska’s Northern Bering Sea

June 1, 2026 — For countless generations, people of the Bering Strait region have relied on the food they harvest from the sea without worrying about harmful algal blooms that threaten seafood eaters in warmer and more southern latitudes.

Now, as the Northern Bering Sea undergoes cascading effects of a warming climate, algal risks pose a new challenge.

The change has been dramatic.

And it has prompted a change in the way Nome youth grow up learning about collecting food from the waters around their home. In early April, Nome high school students traveled to Bethel with their science teacher, where they presented their research at the Western Alaska Interdisciplinary Science Conference held by Alaska Sea Grant.

Algal toxins were present, at very low but detectable levels, in fish they eat.

Sophomore Audrey Bruner-Alvanna was among the group of student researchers. She said young people are concerned about algal blooms, which proliferate in warmer conditions, and their potential effects on wild food resources.

Why an immense marine heatwave off the US west coast has alarmed scientists

May 26, 2026 — An enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists as new data shows its ecological and environmental effects are intensifying.

The unusual area of warm water has persisted since peaking in size during September 2025 and still stretches thousands of miles from the California coastline – more than halfway across the Pacific – affecting a vast triangle-shaped region of oceanic habitats from Hawaii to British Columbia and southward to Mexico.

As recently as early April, marine scientists had hoped that the heatwave might diminish and the worst of its effects might be avoided. However, new projections released last week by the National Oceanic and Atmospheric Administration (Noaa) show it is now expected to expand and strengthen in the months to come.

NOAA predicts below-normal 2026 Atlantic hurricane season

May 22, 2026 — Forecasters with NOAA’s National Weather Service are predicting a below-normal hurricane season for the Atlantic basin this year. NOAA’s outlook for the 2026 Atlantic hurricane season, which runs June 1 to November 30, predicts a 35% chance of a near-normal season, a 10% chance of an above-normal season, and a 55% chance of a below-normal season.

The agency is forecasting a total of 8-14 named storms (winds of 39 mph or higher). Of those, 3-6 are forecast to become hurricanes (winds of 74 mph or higher), including 1-3 major hurricanes (category 3, 4 or 5 with winds of 111 mph or higher). NOAA has a 70% confidence in these ranges. An average season has 14 named storms with seven hurricanes, including three major hurricanes.

“With the most advanced forecast modeling and hurricane tracking technologies, NOAA and the National Weather Service are prepared to deliver real-time storm forecasts and warnings,” said Commerce Secretary Howard Lutnick. “Our experts are integrating cutting-edge tools to ensure communities in the path of storms receive the earliest, most accurate information possible.”

“NOAA’s rapid integration of advanced technology, including AI-based weather models, drones, and next-generation satellite data will deliver actionable science to safeguard the lives and livelihoods of the American people,” said NOAA Administrator Neil Jacobs, Ph.D. “These new capabilities, combined with the unmatched expertise of our National Weather Service forecasters, will produce the most accurate forecasts possible to protect communities in harm’s way.”

Warming Accelerates Ecological State Shift Along Maine Coast

May 20, 2026 — The loss of dense kelp forests along the Maine coast — and the northward proliferation of small, carpet-like turf algae in its place — is accelerating as the ocean warms, according to new research by scientists at Bigelow Laboratory for Ocean Sciences.

Published recently in Ecology, the research shows that warming is facilitating the arrival of new species into the Gulf of Maine, and that the transition from kelp forests to turf reefs has progressed rapidly in recent years. The study, which covers some of the hottest years on record in the region, highlights both the direct and indirect impacts of environmental change on temperate reef ecosystems and the vital services they provide.

“The progression of this shift from kelp forests to turf algae played out right before our eyes,” said Senior Research Scientist Doug Rasher, the senior author on the paper. “We’re digging into what’s driving this transition, and what’s being gained or lost as a result, which allows us to speak more to the future of this ecosystem.”

The new paper builds on previous research published by Rasher’s team, including a study published in 2024 that provided a coastwide assessment on the state of Maine’s kelp forests up to 2018. That analysis, combined with long-term monitoring data from the Department of Marine Resources, drew a causal link between kelp forest decline and rising ocean temperatures. It also documented a widespread shift to turf algae in the southern reaches of the coast. Subsequently, the team examined several of the consequences of that state shift, including changes to the reef’s chemical environment and its food web dynamics.

Rising California sea temperatures trigger legal requirement to protect endangered sea turtles

May 19, 2026 — A heatwave in the Pacific Ocean has triggered a legal requirement to protect loggerhead sea turtles, which are endangered species listed as vulnerable by the International Union for Conservation of Nature.

In a bulletin issued Monday morning, the Center for Biological Diversity (CBD) stated that officials from their office notified the National Oceanic and Atmospheric Administration Fisheries of its legal responsibility to close a large area of the Pacific coast off to swordfish drift gillnets.

A drift gillnet is a type of fishing net that is not fixed to the seabed but allowed to drift with the current and is used to catch fish by having them swim into it. Some drift gillnet fleets can be over 10 kilometers (roughly 6.2 miles) long, and several fleets may be fished by a vessel at once, according to the Food and Agriculture Organization of the United Nations.

Now, with the unusually warm waters off Southern California, wildlife officials say the NOAA Fisheries must act before June 1 to avoid a lawsuit.

Marine heatwave could combine with El Niño in Alaska this summer

May 19, 2026 — Marine heatwaves can wreak all sorts of havoc in Alaska: last year, a marine heatwave in the North Pacific ocean fueled Typhoon Halong, which devastated Alaskan communities. This summer there could be an extra hiccup: a strong El Niño event is likely according to the World Meteorological Organization, which could make the effects of a heatwave even worse.

El Niño events happen as a result of slower trade winds along the equator, which slows down the upwelling of cold water from deep in the ocean and causes overall warmer water conditions.

“We’re expecting a massive El Niño this year,” said Alaska Fisheries Science Center Director Bob Foy during a commercial fisheries trade show in Kodiak on April 16. “And it’s going to be larger than usual, it’s going to make its way to Alaska, we’ll probably see the effects of it this summer.”

The El Niño event could hit as another marine heatwave is brewing. Marine heatwaves happen when the temperature of the ocean is 4-5 degrees Fahrenheit higher than the baseline average for that area. According to research from the University of Alaska, Fairbanks, temperatures in the Gulf of Alaska have been generally trending upwards over the past fifty years, with an average increase of around 0.2 degrees C per decade. But marine heatwaves across the Pacific have hit even higher temperatures, and have become more frequent since the mid 2010s.

What’s a ‘super El Niño’? And other El Niño questions, answered

May 18, 2026 — The odds are in El Niño’s favor right now.

This natural weather phenomenon, part of the El Niño-Southern Oscillation, or ENSO, occurs when warmer-than-average water extends throughout most of the equatorial Pacific Ocean just below the surface. That’s happening now. And powerful bursts of westerly wind have pushed immense amounts of warm water eastward, toward the Niño3.4 region where sea surface temperature, along with other atmospheric conditions, is used to assess the state of ENSO.

On May 14, in its monthly ENSO outlook, the NOAA/National Weather Service Climate Prediction Center gave an 82% chance that El Niño will be in place for the period May through July, which implies that it’ll be here within weeks.

How do experts know when El Niño has arrived?

El Niño conditions are declared when the atmosphere and ocean are in sync and the Niño3.4 sea surface temperature is at least 0.5 degrees Celsius (0.9°F) warmer than the seasonal average.

But just as hurricanes can and do stray from the “cone of uncertainty” at times, it’s vital to remember that El Niño can do much the same. Preparing for the prototypical outcomes is a smart move, as long as you keep in mind that forecasting the El Niño-Southern Oscillation is more a matter of probabilities than certainties.

NOAA now uses a Relative Oceanic Niño Index, or RONI, in which the Niño3.4 value is adjusted relative to the world’s tropical oceans as a whole; the goal is to keep global warming from smudging the signal of El Niño and La Niña events themselves.

Nearly all seasonal forecast ensembles used to predict ENSO at agencies around the world now concur that the imminent event is likely to bring Niño3.4 warming of at least 1.5°C, which would push it into the “strong” category. And some of the ensemble averages are now going well above 2°C, even for the adjusted RONI index. That would put it in the ballpark of the biggest El Niño events in the NOAA database going back to 1950.

Individual ensemble members still cover a fairly broad range, with outcomes varying from a weak event to a record-stomping one, but as shown below, they’re about as close to being unanimous on a significant El Niño as you’re likely to see. (This output is mainly using the traditional pre-RONI index, which tends to run slightly hotter on recent El Niño events.)
