Environmental groups take steps to sue to compel new protections for gray whales

August 28, 2026 — Amid a decade of die-offs and a sharp decline in the population of gray whales that swim along the Pacific coast of North America, three environmental groups are preparing to sue the Trump administration over its failure to bring back Endangered Species Act protections for the animals.

The Center for Biological Diversity, the International Marine Mammal Project and Oasis Earth on Tuesday submitted a notice of intent to sue the National Oceanic and Atmospheric Administration over gray whale protections.

Oasis Earth submitted a petition a year ago to NOAA Fisheries for a threatened or endangered listing to be granted to the Eastern North Pacific gray whale population. But the agency neither issued a 90-day finding on the petition’s validity nor a 12-month finding on the population’s status, as required under the law, the groups’ notice said.

CALIFORNIA: California’s rarest salmon face a narrow window for survival

August 24, 2026 — For California’s most endangered salmon, the difference between surviving and dying may come down to just 15 days.

In a study published Friday in Science Advances, researchers say the chance of juveniles surviving fell by about 73% for every 1.8-degree Fahrenheit increase in average river temperature during those first 15 days.

Sacramento River winter-run Chinook have only one surviving population, with an average of a few thousand fish returning in recent decades.

Shasta Dam keeps the salmon from returning to their original cold-water habitat around Mount Shasta in Northern California. Instead, they spawn in the Sacramento River, where warmer summer water can threaten their developing eggs.

Cold water is released from Shasta Reservoir to keep the river cool enough for salmon eggs to survive, but that water is also needed by farms and cities.

The balance becomes harder in dry years, when there’s less water to go around.

Kohma Arai, who conducted the research as a postdoctoral scholar at UC Davis, said a full summer of spawning doesn’t necessarily mean a successful season.

A Winter at Sea Reveals Seasonal Habits of Whales, Dolphins, and Seabirds in Hawaiʻi

August 21, 2026 — The Hawaiian archipelago is teeming with marine life, and winter brings some of the most exciting activity of the year. It’s a season when many whale and seabird species travel to the islands. Migratory baleen whales such as humpback and minke whales are only found in Hawai‘i in the winter, when they seek warmer waters to breed. Others—including various types of dolphins—rely on this marine ecosystem year-round, but scientists have yet to uncover the details of their wintertime habits.

To close that gap, the Pacific Islands Fisheries Science Center launched a survey in late January 2026. Scientists spent 2 months monitoring these species around the main Hawaiian islands aboard the NOAA Ship Oscar Elton Sette. The mission, called the Winter Hawaiian Islands Cetacean and Ecosystem Assessment Survey, is only the second of its kind.

Six years after the first winter survey, researchers returned to better understand where, when, and how many whales and dolphins use this habitat. The data from these surveys feed into stock assessments, helping us track the status of these species and make informed conservation decisions. This work is especially important for high-priority species like false killer whales, including an endangered population that lives around the main Hawaiian islands.

Winter conditions at sea can be rough, with higher swells and lots of white caps. This makes animals harder to see. But NOAA scientists are experienced with scientific methods that rise to the challenge. During the survey, eagle-eyed visual observers spied more than 200 groups of whales and dolphins, even in difficult conditions. They documented humpback mothers with their calves, bottlenose dolphins riding the ship’s bow, and pantropical spotted dolphins leaping high into the air. Cutting-edge passive acoustic technology helped detect other whales and dolphins that could be heard but not seen.

In these photos, take a look behind the scenes of the survey and find out which species spend their winters in Hawaiʻi.

Giving North Atlantic Right Whales a Check-Up Using Advanced Technology August 17, 2026

August 18, 2026 — This story is part three of a three-part series. Read about how we are listening for North Atlantic right whales with passive acoustics, monitoring them with aerial surveys, and using boats, drones, uncrewed surface vehicles and satellites to learn as much as we can about them and their habitat. In the Northeast, we work with many partners to track right whales, including mothers and calves, using advanced technology to help inform actions that reduce risks to the species.

Passive acoustic monitoring and aerial surveys can provide critical information about endangered North Atlantic right whales. But to assess their health, you need to get closer. That’s why we use these techniques in tandem with vessel surveys. From the water, scientists conduct drone photogrammetry, take biopsies and photographs, and even collect breath samples. Our team flies drones and takes samples from the R/V Selkie, a 23-foot boat, in Cape Cod Bay in the spring and in the Southeast over the winter.

Assessing Right Whale Health Using Drones and Biopsies

Taking and analyzing specialized photos using a drone is called photogrammetry. It allows scientists to measure calf growth rates and check on mother right whales’ health. Mothers nurse their calves but do not eat while they are in the Southeast, so they lose blubber until they start feeding again in the Northeast. Our team gets a longer time series by sampling both in the Southeast calving grounds and Northeast feeding grounds. They also use drone imagery to examine scarring and entanglements. Our team processes the photos using an open source software called MorphoMetriX .

Our vessel survey teams also collect right whale biopsy samples. Along with state partners, they biopsied all but one of the 23 newborn calves this season. Samples provide critical information about the genetics of the calves. Genetics allow us to identify individuals and trace family relationships. These samples can also inform scientists about the health of the calf. That information is added to the North Atlantic Right Whale Catalog.

To biopsy a whale, scientists slowly approach within 30 feet on a small boat and use a specialized hollow biopsy dart discharged by a crossbow. They collect a small sample of skin and blubber—about 1 inch long and the diameter of a pencil. The dart floats, allowing scientists to easily retrieve it for genetic and health analysis. The samples are quickly flash frozen aboard the boat. Ultimately, the samples are stored at the National Institute of Standards and Technology lab in Charleston, South Carolina. They are available for many types of ‘omics research studies. The team hopes that long-term preservation will enable researchers to do the most good for right whales.

Feds to weigh possible new fishing rules and restrictions to protect Mid-Atlantic whales

August 17, 2026 — Federal fisheries officials are beginning a process that could eventually lead to new fishing restrictions along the East Coast designed to protect native whale species.

The National Marine Fisheries Service, part of the National Oceanic and Atmospheric Administration, announced Aug 14 that it intends to conduct an environmental review of potential changes to the Atlantic Large Whale Take Reduction Plan. The plan is intended to reduce deaths and serious injuries of North Atlantic right whales, humpback whales, and fin whales caused by entanglements in commercial trap/pot and gillnet fishing gear along the East Coast.

NMFS stresses that Friday’s publication merely begins a public comment process and is not a proposed federal rule.

Aerial Surveys: Monitoring Right Whales from Above

August 14, 2026 — This story is part two of a three-part series. Read about how we are listening for North Atlantic right whales with passive acoustics, monitoring them with aerial surveys, and using boats, drones, uncrewed surface vehicles and satellites to learn as much as we can about them and their habitat. In the Northeast, we work with many partners to track right whales, including mothers and calves, using advanced technology to help inform actions that reduce risks to the species.

Many North Atlantic right whales migrate thousands of miles to the Southeast and the Mid-Atlantic from mid-November to mid-April. Female right whales give birth in the shallow coastal waters of the Southeast during the winter months. The whales spend the rest of the year feeding in the plankton-rich waters off of the Northeast and Canada.

We take to the skies to monitor this journey. The Northeast Fisheries Science Center’s aerial survey team conducts right whale surveys aboard a NOAA Twin Otter Aircraft. The team has flown 325 hours monitoring whales since January 2026. In the spring, they monitored whales off of New England and the Mid-Atlantic. In June, they joined Fisheries and Oceans Canada (DFO) as part of a Joint Aerial Survey Team, flying out of Charlottetown, Prince Edward Island, Canada. There, they flew 50 hours monitoring aggregations of right whales in the Gulf of St. Lawrence.

US court hears arguments against turtle excluder devices in inshore Louisiana waters

August 14, 2026 — The U.S. Court of Appeals for the Fifth Circuit is considering a challenge to a 2019 NOAA Fisheries rule forcing Louisiana inshore shrimpers to install turtle excluder devices (TEDs).

A TED is a grid of metal bars placed in a trawl net that block larger animals – like turtles – while allowing smaller animals – like shrimp – to pass through. Louisiana shrimpers claim the requirement on inshore vessels is excessive, making their work more difficult and expensive despite little risk to turtles.

From Sound to Satellites: Reducing Risks to North Atlantic Right Whales with Advanced Technology

August 11, 2026 — This story is part 1 of a 3-part series. Read about how we are listening for North Atlantic right whales with passive acoustics, monitoring them with aerial surveys, and using boats, drones, uncrewed surface vehicles and satellites to learn as much as we can about them and their habitat. In the Northeast, we work with many partners to track right whales, including mothers and calves, using advanced technology to help inform actions that reduce risks to the species.

Endangered North Atlantic right whales had a busy winter! NOAA Fisheries and our partners saw 23 right whale mom and calf pairs during the right whale calving season in the Southeast. This is hopeful news for the species. With only 380 North Atlantic right whales remaining, including about 70 reproductively active females, each mother and calf is vital to the species’ recovery. Human impacts continue to threaten the survival of the species.

Reducing risk to these whales is a top priority as they spend the summer in their northern feeding grounds, and technology is helping us do it. With our partners, NOAA Fisheries is monitoring right whales using cutting-edge techniques like real-time passive acoustic monitoring and measuring calf growth rates with drones.

The data we collect inform management and conservation measures that reduce the risks whales face from human impacts, including vessel strikes and entanglements. Our continuous monitoring supports coexistence between marine industries and right whales.

Can Habitat Restoration Help Salmon Recover? Prairie Creek Offers Clues

August 7, 2026 — When any habitat restoration project finishes, a critical question remains: Will the project help threatened fish and other species recover? Answering that question requires rigorous long-term monitoring.

At the Prairie Creek salmon habitat restoration project in Northern California, researchers from NOAA Fisheries’ Office of Habitat Conservation, Cal Poly Humboldt, and other partners have conducted monitoring before, during, and after construction to determine whether the project would improve the survival prospects of threatened Southern Oregon/Northern California Coast coho salmon.

The project transformed a former lumber mill site into wetlands, side channels, and off-channel ponds where juvenile salmon can rest, feed, and grow before migrating to the Pacific Ocean. Juvenile salmon that grow big and strong in freshwater have a better chance of surviving their time in the ocean and returning as adults to spawn.

Early findings suggest that juvenile coho salmon using the restored habitat are growing faster and experiencing higher ocean survival than prior generations from the same watershed. Preexisting monitoring data going back to 2011 gave the team an unusually long baseline against which to measure change. Their findings are also changing what scientists understand about how juvenile salmon use coastal watersheds.

Shrimp industry fights $9.4M loss from federal turtle device mandate

August 6, 2026 — A federal appeals court heard arguments Tuesday over whether Louisiana shrimpers should be required to use turtle protection devices in their nets, a rule the state’s shrimp industry says could have major financial consequences.

The Louisiana Shrimp Association is challenging a federal mandate requiring shrimp boats longer than 40 feet to use Turtle Excluder Devices, or TEDs. The group argues the devices are unnecessary in Louisiana’s inland waters, where members say sea turtles are rarely found.

The requirement was issued by the National Marine Fisheries Service as part of federal efforts to protect endangered and threatened sea turtles from becoming trapped in shrimp nets.

Attorneys representing the shrimp industry argued that the devices are costly to install and can reduce shrimp harvests by collecting trash and debris inside the nets. Association members also contend they have rarely encountered sea turtles while operating in the state’s shallow inland waters over several decades.
