Fishing for genes via eDNA

Just as steelhead trout migrate from saltwater to freshwater and back, Environmental Sample Processors (ESPs)—first developed by the Monterey Bay Aquarium Research Institute (MBARI) for studies in the ocean—have been getting a lot of use in freshwater over the last five years.

This spring, MBARI’s ESP team installed an instrument to collect samples of “environmental DNA” from a coastal creek just north of Monterey Bay. Researchers will use these samples to track populations of threatened steelhead trout, endangered coho salmon, and invasive species in the creek.

In the process, they could help revolutionize environmental monitoring and fisheries management nationwide.

The research is a joint project of MBARI and the Monterey Bay Aquarium, with funding from the Arthur Vining Davis Foundations as part of their newly launched Environmental Engagement, Stewardship & Solutions program. The work is being carried out in collaboration with the National Oceanic and Atmospheric Administration (NOAA). It is part of MBARI’s continuing effort to provide scientific data with direct application for ocean and wildlife conservation. Read more…

El impacto profundo del micro-plástico

(For English, click here.)

(Subtítulos en español están disponibles)

Existe un vasto ecosistema que se extiende muy por debajo de la superficie del océano, en donde la luz es escasa, aumenta la presión y la vida toma formas que bien podrían parecer extraterrestres. Pero incluso ahí, un lugar que parece un mundo apartado de la sociedad humana, nuestra basura plástica se está acumula.

En el mar profundo, resulta desafiante estudiar dónde se acumula ese plástico y cómo afecta a los animales. Por ello, los científicos del Monterey Bay Aquarium en colaboración con nuestros aliados del Monterey Bay Aquarium Research Institute (MBARI) lanzaron un ambicioso proyecto.

Los resultados del estudio en el cual se examina el  micro-plástico en las aguas de la Bahía de Monterey, fue publicado el 6 de junio por la revista Scientific Reports.

“Hemos diseñado este estudio para dar respuesta a una brecha fundamental en nuestro conocimiento sobre el plástico marino una vez que este llega al océano” indica la autora principal Anela Choy, anteriormente investigadora del MBARI y actual profesora del Scripps Institution of Oceanography en San Diego.

El equipo de investigación recolectó datos usando vehículos de comando remoto (ROV, por sus siglas en inglés) —submarinos robóticos diseñados por ingenieros del MBARI— para recolectar muestras de agua en profundidades de entre 200 y 600 metros (unos 650 a 2,000 pies).

También buscaron plástico en animales que cumplen importantes funciones en las redes alimentarias marinas: langostinos pelágicos y seres parecidos a los renacuajos llamados larváceos gigantes, que se rodean con nubes de mucosa cuya función es capturar alimento y, en ellos, los investigadores descubrieron plástico.

“Los problemas como este son extremadamente complicados. Para intentar descubrir la manera de resolverlos se requiere de muchas herramientas distintas,” —menciona Kyle Van Houtan, científico principal del Acuario, quien realizó el estudio en coautoría con Anela y otros nueve investigadores de diversos campos que abarcan desde Fisicoquímica hasta Ecología Marina—.

The deep impact of microplastic

 

(Clic aquí para leer en español)

There’s a vast ecosystem stretching far below the ocean’s surface — one where the light dims, the pressure mounts, and life takes on forms that can seem downright alien. But even there, a place that seems a world apart from human society, our plastic trash is building up.

In the deep sea, it’s a challenge to study where that plastic accumulates and how it affects animals. So scientists at the Monterey Bay Aquarium and our partners at the Monterey Bay Aquarium Research Institute (MBARI) launched an ambitious collaboration.

The resulting study, which examined microplastic in the waters of Monterey Bay, was published June 6 in the journal Scientific Reports.

“We designed this study to answer a fundamental gap in our knowledge of marine plastic once it reaches the ocean,” says lead author Anela Choy, a former MBARI researcher and now a professor at the Scripps Institution of Oceanography in San Diego.

The research team gathered data by using remotely operated vehicles (ROVs), robotic submarines designed by MBARI engineers, to collect water samples at depths from 200 to 600 meters (about 650 to 2,000 feet).

They also searched for plastic in animals with important roles in the marine food web: pelagic red crabs; and tadpole-like creatures called giant larvaceans, which surround themselves with clouds of mucus that capture food — and, as the researchers discovered, plastic.

“Problems like this are extremely complicated. To try and figure out how to solve them, you need a lot of different tools,” says Aquarium Chief Scientist Kyle Van Houtan, who co-authored the paper with Anela and nine others, tapping fields from physical chemistry to marine ecology. Read more…

Field studies of ocean acidification

Sometimes, research has to venture out of the lab and into the wild. That’s the basis for a long-term Monterey Bay Aquarium Research Institute (MBARI) project to study how the ocean’s changing chemistry will affect marine life.

Ocean acidification is a change in seawater pH (and other elements of the ocean carbonate system) as the ocean absorbs excess carbon dioxide from the atmosphere. This change will become more pronounced as people continue to burn fossil fuels.

“It’s important to try to get a better understanding of what impact that will have,” says George Matsumoto, senior education and research specialist at MBARI.

In a more acidic ocean, the minerals used to form calcium carbonate are less abundant, making it more difficult for marine species—from tiny sea snails to oysters and crabs—to build shells or skeletons. MBARI marine ecologist Jim Barry says researchers are working to understand the impact not just on individual animals, but also on broader ecosystems. Read more…

Counting fish like a BOSS

Counting fish in the ocean isn’t easy—particularly when they swim among jagged rocks and along undersea cliffs hundreds of feet below the waves. To help, the Monterey Bay Aquarium Research Institute has developed a new camera system called the Benthic Observation Survey System, or BOSS.

A five-foot metal cylinder that features an array of cameras and lights, the BOSS is designed to be lowered from a ship to the seafloor and land upright on rocky terrain. There, it will help scientists survey fish populations using eight high-definition video cameras.

Researchers and policymakers need this technology to find out more about life in the ocean and how to better protect it. MBARI developed the BOSS with input from investigators at Moss Landing Marine Laboratories and The Nature Conservancy .

“The scientists I’m working with are looking at areas that previously were heavily fished out,” explains MBARI staff engineer Chad Kecy, who led the effort to design and build the BOSS. Chad and his colleagues are trying to get a better understanding of how fish populations are recovering in these areas, what species are present, how big they are and where they swim.

Chad likes the challenge of solving problems on a tight timeline. The BOSS had to be built and tested in a matter of months, because the scientists who planned to deploy it already had research trips scheduled on boats that could not wait.

“Now the scientists are busy analyzing all this video they were able to capture with the tool that we developed,” Chad says.

Mary Gleason, science director for The Nature Conservancy’s California Oceans Program and who helped develop the BOSS, says it can fill important gaps in existing data, based on its inaugural voyage: “We showed that we could get 400 video surveys done across 300 miles of coastline during one three-week cruise. So that’s pretty efficient in terms of data quantity.”

Julie Packard: Honoring Bill Gates for his work to protect our planet, improve the human condition

The David Packard Award honors business leaders who work to make the planet more sustainable.

Since 2014, the Monterey Bay Aquarium has periodically honored leaders whose activities and achievements embody the qualities of thought and action that my father, David Packard, held dear. These individuals have effectively worked to make the future of our planet surer and more sustainable.

This year, we recognized visionary Microsoft co-founder and philanthropic innovator Bill Gates. Bill has done so much to improve the human condition—by harnessing technology to advance social good, and by launching bold philanthropic initiatives to make lives better around the world and ensure that everyone has the opportunity to live a healthy, productive life.

We honored Microsoft co-founder Bill Gates for his work, as a business leader and a philanthropist, to improve the human condition.

We paid tribute to the scope and the focus of Bill’s thinking and his commitment to using science and technology to improve the future for the people on our planet. It’s a conviction he shares with my father. Because of the extraordinary success of Microsoft, the Gates Foundation has had the resources to tackle some of the largest problems confronting the world, and Bill and Melinda’s vision and strategic approach are yielding extraordinary results.

Our 300 guests at the award dinner—representing Silicon Valley’s most iconic technology company leaders, along with global ocean conservationists and philanthropists—heard from Bill and our award dinner chair, Meg Whitman, during an engaging “fireside chat”. They covered topics from the role technology can play in environmental conservation, to new approaches philanthropy can bring to pressing global challenges, and the importance of optimism.

MBARI puts science and technology to work for ocean health

The week of September 10, people from around the world are gathering in San Francisco for the Global Climate Action Summit. Convened by the State of California, the Summit brings together leaders—representing nations, states, cities, companies, investors and citizens—to celebrate climate action, and step up their ambitions to meet the targets set by the Paris Agreement. Climate scientist Heidi Cullen, director of communications and strategic initiatives for the Monterey Bay Aquarium Research Institute, shares some of the studies MBARI has undertaken to understand the impact of climate change on ocean ecosystems.

Caring about the ocean means caring about climate change. From increasing ocean acidification to coral bleaching to harmful algal blooms, climate change—caused by the burning of fossil fuels—is having a profound and sometimes deadly impact on our ocean. I am tremendously hopeful that recent advances in science and technology will help us better understand and protect the planet’s largest ecosystem. We rely on it for so much!

At MBARI, engineers and scientists are developing new tools to study and monitor ocean change. Innovative technology is improving the way we access, sample, measure and visualize the rapid changes taking place across the ocean—from the surface down to the bottom of the sea. It is also improving the way we manage ocean resources. I want to share three exciting examples of cutting-edge ocean research happening at MBARI right now. This research is helping us better understand how climate change is already impacting our living ocean, and how we can better protect it in the future. Read more…
