Even baby fish are eating plastics, Hawaii study finds

November 12, 2019 — Recent evidence has shown that adult fish are eating plastics in the ocean and suffering from perils such as malnutrition and toxicant buildup.

Now, for the first time, a study conducted in Hawaii shows baby fish are ingesting tiny plastics, too.

The research, published today in the journal Proceedings of the National Academy of Sciences, found that both young coral reef fish and open-ocean species are consuming plastic as early as days after they are spawned.

Working in the waters off West Hawaii, an international team of researchers focused on surface slicks — naturally occurring ribbons of smooth water at the ocean surface that are formed when underwater waves converge near coastlines, according to a NOAA news release. These biologically rich ribbons of water aren’t always visible to the eye but are commonly seen, especially if wind conditions are right.

Found in coastal waters around the world, the surface slicks accumulate high concentrations of plankton, a key food source that lures larval fish in huge numbers. These watery nurseries harbor an impressive variety of species from a range of habitats, ranging from the deep ocean waters to shallow-water reefs.

Rep. Joe Cunningham: A healthy ocean in 2050? We need to act now.

November 8, 2019 — The ocean is the lifeblood of our planet. It covers three quarters of the globe, produces more than half our oxygen, supports a wide range of marine fisheries that feed the planet, and absorbs 30 percent of the carbon dioxide we emit and 90 percent of the heat caused by those emissions.

In short, the ocean plays a critical role in our lives and livelihoods. And it’s just as critical that we do everything we can to protect it.

By 2050, the global population is expected to reach 9.7 billion people. While the projections regarding the impact that this population and their actions and emissions will have on the ocean may vary, none of them are good. Without definitive action now, scientists predict that by 2050:

• World fish stocks will be driven to collapse;
• Average sea levels will rise by 30-34 centimeters, increasing coastal erosion and exacerbating storms, flooding cities and coastal communities like Charleston;
• The ocean is expected to contain more plastics than fish (by weight); and
• The world’s coral reefs will be wiped out, increasing threats to coastal communities from storm surges and a loss of fish stocks that rely on corals for survival.

Trump Sued For Failing To Protect Hawaii’s Cauliflower Coral

October 11, 2019 — The Center for Biological Diversity said Thursday that it is suing the Trump administration for failing to protect cauliflower coral around the Hawaiian Islands.

“The bushy, shallow-water coral species has been devastated by ocean warming triggered by human-caused climate change,” according to a press release.

The warming is due to a “marine heat wave … now hitting Hawaii’s coral reefs hard, and researchers predict massive coral bleaching and death.”

The coral species is estimated to have declined by 36% from 1999 to 2012, and conditions are expected to worsen.

“Cauliflower coral is like the canary in the coal mine of our warming oceans. Marine life around Hawaii will suffer without bold actions to protect coral reefs,” said Maxx Phillips, the center’s Hawaii director. “Hawaii’s coral reefs are dying and they need our help. Letting colorful corals bleach white and die indicates an ocean becoming less bountiful and biodiverse.”

Rubio, Schatz, Scott, Hirono Introduce Bill to Restore and Conserve America’s Coral Reefs

August 2, 2019 — The following was released by The Office of Senator Marco Rubio (R-FL):

This week, U.S. Senators Marco Rubio (R-FL), Brian Schatz (D-HI), Rick Scott (R-FL), and Mazie Hirono (D-HI) and Representatives Darren Soto (D-FL) and Jenniffer González-Colón (R-PR) introduced the Restoring Resilient Reefs Act of 2019, bipartisan and bicameral legislation that would reauthorize and modernize the Coral Reef Conservation Act of 2000. The Coral Reef Conservation Act, which expired 15 years ago, was designed to promote the conservation of our nation’s reefs. The Restoring Resilient Reefs Act authorizes five years of directed federal funding and technical assistance to states for the restoration and management of coral reef ecosystems, encourages innovative new Coral Reef Stewardship Partnerships among resource management agencies, research centers, and community stakeholders, and codifies and updates the U.S. Coral Reef Task Force.

Additional original cosponsors of the House bill include Representatives Charlie Crist (D-FL), Brian Mast (R-FL), Stephanie Murphy (D-FL), Amata Coleman Radewagen (R-AS), and Tulsi Gabbard (D-HI). A summary of the bill is available here and a section by section is available here.

“I saw the devastated condition of our coral reefs firsthand when touring the Florida Keys National Marine Sanctuary in February, and I promised a comprehensive response,” Rubio said. “This important bipartisan bill will ensure federal agencies are partnering effectively with state and local governments, as well as the communities who rely on the vitality of these critical habitats. Florida’s Reef Tract is an integral component of the economic and ecological character of Florida, and the Restoring Resilient Reefs Act of 2019 will ensure future generations will be able to enjoy this natural wonder.”

“From never-before-seen levels of bleaching in the Pacific, to unprecedented devastation from disease in the Atlantic, coral reefs need urgent help. Our bill gives local governments and communities the federal resources to help save Hawaii’s corals,” Schatz said.

“People from across the world come to Florida because of the state’s natural beauty. During my eight years as Governor, Florida’s annual investments to preserve the environment increased by $1 billion to make sure future generations can enjoy all that Florida has to offer. Today, I’m proud to join Senator Rubio, Senator Schatz, Senator Hirono and our colleagues in the House to introduce the Restoring Resilient Reefs Act of 2019, which will build on our efforts and help restore and protect our coral reef ecosystems,” Scott said.

“Coral reefs provide essential ecosystem services to not only our oceans, but also to our island and coastal communities. The long-term ecological and economic impacts of coral bleaching pose serious threats to our way of life,” Hirono said. “The Restoring Resilient Reefs Act would provide important tools to preserve and sustain the condition of our coral reef ecosystems through community-based management programs. Our bill is a step in the right direction to ensuring that communities that depend on healthy oceans, like those in Hawaii, have the resources they need for protecting coral reefs.”

Earth’s oceans may be way hotter than scientists realized — here’s how worried you should be

November 2, 2018 — The oceans are the world’s thankless, built-in air purifiers.

Over the past couple hundred years, as humans have burned coal, cleared forests, put gas-powered cars and trucks on the road, and run air conditioners and refrigerators, the oceans have been quietly gathering up most of the carbon emissions those activities spew into the air. They’ve also absorbed most of the excess heat that those gases have trapped on the planet.

Previous estimates suggested that the world’s oceans have collectively taken in more than 90% of the excess heat energy that our carbon emissions have kept on Earth.

But a new report published in the journal Nature on Wednesday suggests it’s worse than that. The research shows that scientists have been measuring the amount of heat in the oceans incorrectly, so the waters have actually absorbed far more heat than previously thought.

“If we think the ocean is warming more than we thought, it means the Earth is warming more than we thought, and that means the Earth is more sensitive to our emissions,” lead study author Laure Resplandy, an assistant professor of geosciences at Princeton, told Business Insider.

Scientists have long warned that we have to curb our reliance on fossil fuels to avoid a future of regular, catastrophic climate disasters. But Resplandy said the new findings in her report show that avoiding a future “Hothouse Earth” scenario will be even harder than anticipated. Specifically, that means it will be more challenging to avoid flooding from sea level rise in coastal cities, violent hurricanes, and the death of nearly all of Earth’s coral reefs.

The Invasice Venomous Lionfish is Killing Atlantic Reefs. So Please Eat It.

October 24, 2018 — KEY LARGO, Fla. — What do you do with an invasive fish, covered from head to fin with venomous spines as sharp as hypodermic needles; a fish that can’t be caught with a rod or in a trawling net as it multiplies rapidly, deep in our oceans, flummoxing fishermen and scientists alike?

Conservationists are hoping you eat it.

The Indo-Pacific native lionfish arrived in the Atlantic about a decade ago, the product of well-meaning aquarium owners who released their charges into the ocean, not realizing they reproduce at an alarming rate, prey on more than 70 species of fish and hasten the dying-off of any coral reef they alight on. Scientists describe their invasion into Florida’s waters in the same words noted Key West fisherman Ernest Hemingway used to describe the onset of bankruptcy: slowly, and then all at once. Now estimated to number as many as 1,000 fish per acre, lionfish also have no known predators — except humans.

Expanded protection of coral reefs in Gulf of Mexico may not be ready for approval until 2020

September 13, 2018 — A plan to expand the network of federally protected coral reef systems in the Gulf of Mexico may not be ready for approval by the Trump administration until early 2020, officials said Wednesday.

That means about five years will have passed since officials first began discussing in 2015 expanding the Flower Garden Banks National Marine Sanctuary, located about 100 miles off the coast of Galveston.

The sanctuary designation, which prevents over fishing and harassment of marine life in the area, currently stretches across 56 square miles, or three banks. In May, the sanctuary’s advisory council approved a proposal that would expand that area to 206 square miles, or 17 banks.

But officials have identified some potential tweaks. For example, the new plan actually would eliminate some of the protected area around Stetson Bank, one of the three current banks.

“There has not been a final decision how proceed,” sanctuary Superintendent G.P. Schmahl said during a Wednesday advisory council meeting, adding that officials likely would adjust the Stetson Bank boundaries.

According to the Flower Garden Banks website, there are several more steps to go in the process. For example, the National Oceanic and Atmospheric Administration, which oversees the 13 federally designated national marine sanctuaries, still must ask the Department of Interior to analyse the plan to understand how it will impact energy and mineral resource development.

‘Storminess’ Could Make Fishing More Risky as Climate Warms

July 2, 2018 — Tens of thousands of people die every year trying to catch fish to eat or sell, and weather is one of the biggest hazards to lives and equipment. The International Red Cross estimates that 3,000–5,000 people, mainly fishers, are killed by intense thunderstorms on Africa’s Lake Victoria each year. In 2013, Typhoon Haiyan destroyed some 30,000 fishing boats in the Philippines.

The dangers of fishing are no secret, but a warming planet could make the job even more risky. A team of researchers in England is calling for a closer look at how increasingly stormy weather will affect global fisheries.

In a study published in the journal Nature Climate Change, they warn that nastier weather in the future will make fishing more dangerous for millions of fishers and, by reducing catches, could threaten the health and well-being of billions of people who eat seafood. The biggest challenge is that few have studied this question. Although there’s been plenty of research on how ocean warming could reduce fish catch in the next 50–100 years, they said, changing “storminess” could actually be a more immediate, catastrophic issue.

“We really want to encourage more research in this area, because we think it’s really critical for the future,” said lead author Nigel Sainsbury, a scientist at the University of Exeter’s Environment and Sustainability Institute.

Already, scientists have looked at how large storms can damage coral reefs, cause fish to evacuate large areas and flood estuaries with salty ocean water. Some storm systems may also benefit fish by strengthening ocean upwelling that allows phytoplankton and zooplankton – food at the base of the marine food chain – to thrive, according to research led by United States National Marine Fisheries Service scientists.

The Ocean Is Getting More Acidic —What That Actually Means

June 18, 2018 — Grace Saba steadies herself on the back of a gently rocking boat as she and her crew slide a six-foot long yellow torpedo into the sea. A cheer erupts as the device surfaces, turns on its electronic signal, and begins a three-week journey along the New Jersey coast.

“It’s taken seven years to get this done,” said Saba, who has been working on this experiment since 2011. “I’m so happy, I think I might cry!”

Saba is an assistant professor of marine ecology at Rutgers University, where she is studying how fish, clams, and other creatures are reacting to rising levels of ocean acidity. Acidification is a byproduct of climate change; a slow but exorable real-life experiment in which industrial emissions of carbon dioxide into the atmosphere are absorbed and then undergo chemical reactions in the sea. Rising ocean acidity has already bleached Florida’s coral reefs and killed valuable oysters in the Pacific Northwest.

Now scientists like Saba want to know what might happen to animals that live in the Northeast, a region home to commercially important fishes, wild stocks of quahogs (clams), scallops, and surf clams that can’t swim away from growing acidic waters.

“They are just stuck there,” Saba said.

Saba’s torpedo-like instrument is actually an underwater drone, known as a Slocum glider, that is carrying an ocean acidity sensor. This is the first time that oceanographers have married the two technologies—glider and pH sensor—to get a big-picture view of changes underway in the commercially important fishing grounds of the Northeastern United States.

In the Philippines, Dynamite Fishing Decimates Entire Ocean Food Chains

June 18, 2018 — Nothing beats dynamite fishing for sheer efficiency.

A fisherman in this scattering of islands in the central Philippines balanced on a narrow outrigger boat and launched a bottle bomb into the sea with the ease of a quarterback. It exploded in a violent burst, rocking the bottom of our boat and filling the air with an acrid smell. Fish bobbed onto the surface, dead or gasping their last breaths.

Under the water, coral shattered into rubble.

The blast ruptured the internal organs of reef fish, fractured their spines or tore at their flesh with coral shrapnel. From microscopic plankton to sea horses, anemones and sharks, little survives inside the 30- to 100-foot radius of an explosion.

With 10,500 square miles of coral reef, the Philippines is a global center for marine biodiversity, which the country has struggled to protect in the face of human activity and institutional inaction. But as the effects of climate change on oceans become more acute, stopping dynamite and other illegal fishing has taken on a new urgency.
