Mote-Led Initiative to Restore Corals

November 14, 2018 — Mote Marine Laboratory and partners will restore 70,000 coral “seeds” across 130 acres of depleted Florida reefs over three years — prioritizing coral genetic varieties resilient to disease and climate change impacts — thanks to a grant of nearly $1.5 million announced today by the National Fish & Wildlife Foundation (NFWF), National Oceanic and Atmospheric Administration (NOAA) and partners.

The grant challenges Mote and its supporters to raise matching funds and achieve the greatest possible impact for the Florida Reef Tract and those who depend on it. Florida has the planet’s third-largest shallow-water coral reef system, which underpins the state’s marine ecosystems, supports over 70,000 local jobs, draws $6.3 billion to Florida’s economy and serves as the primary front line of coastal resiliency defense from major storms.

Resilient coastlines are the focus of Mote’s grant and 34 others totaling $28.9 million, awarded by National Coastal Resilience Fund (NCRF), a partnership of NFWF, NOAA, Shell Oil Company and TransRe. These grants were made possible when congress provided funding for Title IX of the National Oceans and Coastal Security Act. Together, the grants are expected to generate $38.3 million in matching contributions for a total conservation impact of $67.2 million.

Industry, agencies working to avoid whale entanglements

November 14, 2018 — LONG BEACH, Calif. — Whale entanglements off the West Coast and potential solutions to the escalating problem are the focus of a new report including the presentations and observations of fishermen, biologists and fisheries managers who gathered at an August workshop.

In recent years, growing populations of humpback and gray whales, changing ocean conditions and prey locations, and later crab season openings have led to more whales getting entangled in fishing gear, such as the ropes and floats that mark the location of crab pots. In 2017 there were 31 confirmed entanglements off the West Coast, including two humpbacks and a gray whale off the Washington coast, according to a press release from NOAA Fisheries. While NOAA concedes these entanglements are still proportionally rare, they sometimes lead to the deaths of entangled whales, so both fishermen and fisheries managers are seeking solutions.

To understand how and where rope and other gear entangles whales and to find ways to address the problem, the Pacific States Marine Fisheries Commission (PSMFC) and NOAA Fisheries’ West Coast Region convened a two-day workshop in Long Beach, California, in August. This “forensic workshop” was also supported by The Marine Mammal Commission, Oregon Sea Grant, and the Aquarium of the Pacific. The report from the workshop is now available at tinyurl.com/whale-entanglement-report.

The report provides the notes and presentations from the 31 California, Oregon, and Washington experts who attended. Participating were Dungeness crab fishermen; gear specialists; marine mammal biologists and disentanglement specialists; conservation groups; and federal, tribal and state agency representatives.

New study: Chesapeake oyster decline not due to overfishing

November 14, 2018 — Warmer winters, rather than overharvesting, caused the steep decline of oysters and other commercially valuable shellfish in the Chesapeake Bay and elsewhere along the Atlantic coast, according to a controversial new study that’s getting pushback from some scientists.

The study, which appeared in Marine Fisheries Review, a quarterly journal of the National Oceanic and Atmospheric Administration, says that multi-year stretches of mild temperatures in normally weather months altered the food web in coastal waters. That impaired the growth and reproduction of oysters, quahogs, soft-shell clams and scallops, scientists said. It also led to increased predation on shellfish larvae and outbreaks of diseases.

“The temperatures got warm and that changed the whole environment, so [the oyster diseases] MSX and Dermo could flourish,” said Clyde MacKenzie, Jr., the study’s lead author and a longtime researcher at NOAA’s Northeast Fisheries Science Center at Sandy Hook, NJ. Mitchell Tarnowski, who runs the annual fall oyster survey for Maryland’s Department of Natural Resources, is the co-author.

The paper’s conclusions, especially its dismissal of overfishing as a factor in Chesapeake oyster declines, came under fire from scientists with the University of Maryland Center for Environmental Science and Chesapeake Bay Foundation. Its publication comes as the DNR prepares to release a first-ever stock assessment of the oyster population in the Upper Chesapeake, including an evaluation of whether current harvest levels are sustainable.

The scientific consensus has long been that overharvesting, disease and habitat loss over the decades devastated the Bay’s oyster population, with some estimates putting it in recent years at 1 percent or less of historic levels of abundance. From an annual commercial harvest of nearly 17 million bushels in 1880, landings have trended downward, hitting historic lows in 2003-04 of just 50,000 bushels. The harvest has rebounded some since then, though much of the gain has come via private oyster farming, especially in Virginia.

Fisherman Risks His Life to Save a Humpback Whale

November 14, 2018 — As they headed back toward the central California coast after fishing for slime eel in the Pacific Ocean, Sam Synstelien and Nicholas Taron made a troubling discovery: a humpback whale was entangled in a buoy’s rope, frantically trying to free itself.

Synstelien immediately called the U.S. Coast Guard but was told it might take a few hours for someone to get there. The two commercial fishermen thought that could be too long for the whale to survive its predicament.

“(The whale) was just swimming in counter-clockwise circles,” Taron told NBC Bay Area. “You could tell he was stressed and being held to the bottom.”

Instead of waiting for the Coast Guard or leaving the whale behind, Synstelien and Taron decided to try to save its life. They cranked up the volume on the radio of their 27-foot-long boat (aptly named “Persistence”) and shouted into the microphone to get the frantic, 40-foot-long humpback’s attention.

“We were screaming at the whale, ‘You’re either going to help us out and quit swimming away or else, like, good luck,’” Taron said.

The two were able to cut through the rope wound around the whale’s tail, but the rope still entangled its midsection. Synstelien decided to try to free it himself. As Taron recorded a video on his cell phone, Synstelien jumped onto the whale and shimmied up its back.

Scientists acknowledge key errors in study of how fast the oceans are warming

November 14, 2018 — Scientists behind a major study that claimed the Earth’s oceans are warming faster than previously thought now say their work contained inadvertent errors that made their conclusions seem more certain than they actually are.

Two weeks after the high-profile study was published in the journal Nature, its authors have submitted corrections to the publication. The Scripps Institution of Oceanography, home to several of the researchers involved, also noted the problems in the scientists’ work and corrected a news release on its website, which previously had asserted that the study detailed how the Earth’s oceans “have absorbed 60 percent more heat than previously thought.”

“Unfortunately, we made mistakes here,” said Ralph Keeling, a climate scientist at Scripps, who was a co-author of the study. “I think the main lesson is that you work as fast as you can to fix mistakes when you find them.”

The central problem, according to Keeling, came in how the researchers dealt with the uncertainty in their measurements. As a result, the findings suffer from too much doubt to definitively support the paper’s conclusion about how much heat the oceans have absorbed over time.

The central conclusion of the study — that oceans are retaining ever more energy as more heat is being trapped within Earth’s climate system each year — is in line with other studies that have drawn similar conclusions. And it hasn’t changed much despite the errors. But Keeling said the authors’ miscalculations mean there is a much larger margin of error in the findings, which means researchers can weigh in with less certainty than they thought.

“I accept responsibility for what happened because it’s my role to make sure that those kind of details got conveyed,” Keeling said.

The study’s lead author was Laure Resplandy of Princeton University. Other researchers were with institutions in China, Paris, Germany and the U.S. National Center for Atmospheric Research and Geophysical Fluid Dynamics Laboratory.

Less whale tours, dams: Washington task force returns with guidance on Tuesday

November 13, 2018 — Gov. Jay Inslee first assembled the group in March, inviting representatives from tribal, federal, local and other state governments, as well the private and non-profit sectors, to come together and develop longer-term action recommendations for orca recovery and future sustainability.

The task force’s main goals were to reduce the harm of the three main challenges facing orcas: pollution; lack of access to their primary prey, the chinook salmon; and boat traffic noise.

And though it’s only been about six months since Gov. Jay Inslee created a task force to draw up some guidelines about how to help the local Southern Resident orca population, it feels like a different world for the whales.

The pods had a rocky summer, starting with the latest census data showing that their population had dipped to a 30-year low, having lost 25 percent of the local orcas since the 1990s. Shortly after that, Tahlequah made headlines around the world when she swam with the body of dead calf for a week, covering 1,000 miles.

Later in the summer, the youngest member of the J-pod fell ill. Despite many researchers attempting to help get her back up to fighting weight, her disappearance and assumed death marked another disheartening chapter to the summer of the Southern Residents.

It’s especially discouraging considering that the outlook is a lot sunnier up north — the Northern Resident orca population has doubled since 1974, to a total of 309.

But the end of the summer brings a few bright spots: Multiple Southern Residents appear to be pregnant, and the task force’s guidelines are finally being filed.

“I look at 2018, and I hope this is the low point,” Barry Thom, regional administrator for NOAA fisheries West Coast Region, said a hearing regarding the orcas in Friday Harbor earlier this year. “The clock is running out on killer whale recovery, and it is heart wrenching to see.”

Draft recommendations released for public comment include significantly increasing investment in restoration and acquisition of habitat in areas where chinook salmon stocks most benefit Southern Resident orcas, immediately funding acquisition and restoration of nearshore habitat to increase the abundance of forage fish for salmon, and determine whether the removal of some dams would provide benefits to the Southern Resident orca population.

Divers haul in large amount of debris from marine monument

November 13, 2018 — A team of divers hauled in nearly 165,000 pounds (75,000 kilograms) of abandoned fishing nets and plastic waste during a cleanup expedition at Papahanaumokuakea Marine National Monument, federal officials said.

The 18 divers left Sept. 19 and returned Oct. 29 from a trek to the chain of isles and atolls located 1,200 miles (1,931 kilometers) northwest of the main Hawaiian islands, according to the National Oceanic and Atmospheric Administration, which runs the expeditions.

The divers hauled in about 82 tons (74 metric tons), which is comparable to the weight of 45 mid-sized cars or one space shuttle, NOAA said.

The team of divers from NOAA Fisheries and University of Hawaii’s Joint Institute of Marine and Atmospheric Research sorted out the debris Friday.

The group split the debris into categories such as plastic laundry baskets, fishing nets, tires, buoys and smaller personal-care items such as plastic toothbrushes and combs.

Papahanaumokuakea Marine National Monument is uninhabited by humans. But due to its central location in the system of circulating currents called the North Pacific Gyre, the debris has been carried by currents to its shores for decades.

NOAA’s marine debris team has been going on expeditions to the Northwestern Hawaiian Islands almost yearly to survey and remove litter since 1996. Cumulatively, including the last mission, teams have collected about 2 million pounds (0.91 million kilograms) of debris.

The litter does ecological damage at Papahanaumokuakea, said NOAA’s Kevin O’Brien, who served as chief scientist for the mission this year.

Veterans get foothold in marine science through NWFSC internship

November 13, 2018 — The following was released by NOAA:

Two veterans will mark this Veterans’ Day as part of research teams at NOAA Fisheries’ Northwest Fisheries Science Center (NWFSC), one focused on the ecological response to dam removal and the other on the effects of ocean acidification on Dungeness crab and krill.

Katherine Rovinski, who served seven years in the Navy as a surface warfare officer, and Shawna Worley, an Army intelligence analyst for six years, just began NWFSC’s internship program for veterans, known as the Washington Veterans Corps Fisheries Program. The program offers veterans a foothold towards a career in marine science, while also supplementing the Science Center’s research staff.

“This is the perfect opportunity for me to learn more about the science, and what it’s like to work at NOAA,” said Worley, 33, who is working with NWFSC researcher Sarah Morley’s team tracking changes in the Elwha River system following the removal of two large dams that once blocked it. “This is exactly what I’m interested in studying and learning more about.”

NOAA Fisheries West Coast Region and the NOAA Restoration Center created the internship program in 2016 in partnership with NWFSC, Washington’s Department of Veterans Affairs and Veterans Conservation Corps. This is its third year. Barney Boyer, the first veteran to complete the program, started graduate school in fisheries last year on a full scholarship.

Rovinski, 29, said she is impressed at how widely NOAA Fisheries staff share information in all directions, avoiding silos that otherwise can form. She noted regular webinars and cross-division meetings that help employees learn more about science and the surrounding issues. “There is a lot of cross-pollination going on,” she said.

After earning a bachelor’s degree from Maine Maritime Academy and a master’s from the University of Washington, Rovinski spent last summer aboard Sound Experience’s Adventuress, a tall ship that sails the Salish Sea on educational trips for schools and other youth groups. She heard about the NWFSC’s internship program, and immediately thought, “That’s what I’m looking for.”

“I’ve known about NOAA since the first time I looked at charts,” so it didn’t need much explaining, she said.

Rovinski is working out of the Mukilteo Research Station, just across the water from Whidbey Island, where she lives. She is assisting with research looking at the effect of ocean acidification on Dungeness crab, a staple of coastal life in the Northwest, and krill, the tiny, plankton-like organisms that support much of the marine food chain including salmon, steelhead, and other key species.

One of the first challenges is keeping the krill alive in the laboratory environment. “We’re trying to recreate the conditions in the environment so they will eat,” she said.

Worley has spent the first few weeks of her internship cataloging samples collected from the Elwha River, where NWFSC scientists are documenting ecological changes following dam removal. She is particularly interested in how marine nutrients move from fish into the environment, fertilizing its productivity.

She is also reading everything she can on the Elwha.

“I cannot say how great it is to have someone so engaged, so dedicated, and so sharp to help support our work,” said Morley, who leads the lab at NWFSC’s Montlake campus where Worley is based. “It’s been a great fit.”

Warm temps hurt shellfish, aid predators

November 13, 2018 — Valuable species of shellfish have become harder to find on the East Coast because of degraded habitat caused by a warming environment, according to a pair of scientists that sought to find out whether environmental factors or overfishing was the source of the decline.

The scientists reached the conclusion in studying the decline in the harvest of four commercially important species of shellfish in coastal areas from Maine to North Carolina – eastern oysters, northern quahogs, softshell clams and northern bay scallops. They reported that their findings came down squarely on the side of a warming ocean environment and a changing climate, and not excessive harvest by fishermen.

One of the ways warming has negatively impacted shellfish is by making them more susceptible to predators, said the lead author of the study, Clyde MacKenzie, a shellfish researcher for the National Oceanic and Atmospheric Administration who is based in Sandy Hook, New Jersey.

“Their predation rate is faster in the warmer waters. They begin to prey earlier, and they prey longer into the fall,” MacKenzie said. “These stocks have gone down.”

MacKenzie’s findings, the product of a collaboration with Mitchell Tarnowski, a shellfish biologist with the Maryland Department of Natural Resources, appeared recently in the journal Marine Fisheries Review. The findings have implications for consumers of shellfish, because a declining domestic harvest means the prices of shellfish such as oysters and clams could rise, or the U.S. could become more dependent on foreign sources.

NOAA Issues Report on Protecting North Atlantic Right Whales

November 12, 2018 — NOAA Fisheries researchers have been looking into how to preserve the shrinking population of critically endangered North Atlantic Right Whales.

Officials have concluded that the surest way of protecting the species is by preserving the lives of adult females in the population as a way to promote population growth and recovery.

According to Royal Society Open Science, most right whale deaths are attributed to entanglement in fishing gear and collisions with ships.
