The spirit of collaboration aboard Gulf of Mexico cruise

This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of Mexico yet. Set to depart today, July 18th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through international waters with 24 scientists from the United States, Mexico and Cuba on board.

This comprehensive month-long effort is driven by the growing collaboration within the ocean acidification science community and the multitude of communities that rely on the changing Gulf. The cruise will be the first all inclusive research cruise to document ocean acidification impacts to US living marine resources in the Gulf of Mexico, which is called for under the Federal Ocean Acidification Research And Monitoring Act of 2009 (FOARAM).

Team deciphers secrets of undersea chemical reaction; can it reduce CO2 in the atmosphere?

Scientists speed up a natural process that occurs deep in the ocean, raising the possibility that humans could help the Earth cope with greenhouse gases

Scientists at USC and Caltech have accelerated a normally slow, natural chemical reaction by a factor of 500, which could store and neutralize carbon in the deepest recesses of the ocean without harming coral or other organisms.

For the first time ever, the USC-Caltech team was able to measure very precisely the reaction rate of calcite, a form of calcium carbonate, as it dissolved in seawater enhanced by a common enzyme, carbonic anhydrase. That’s the same enzyme that maintains the acid-base balance in the blood and tissue of humans and other animals.

New model reveals how ocean acidification challenges tiny sea snails off U.S. West Coast

A tiny sea snail, sometimes called a sea butterfly because of how it flutters about traveling the ocean currents, is part of the diet for such valuable fish as salmon and cod off the U.S West Coast.

A new study models the journey of this delicate plankton from offshore to nearshore waters, describing how changing ocean chemistry along this journey affects their condition.

FSU researcher makes deep-sea coral reef discovery in depths of North Pacific

Scientists have long believed that the waters of the Central and Northeast Pacific Ocean were inhospitable to deep-sea scleractinian coral, but a Florida State University professor’s discovery of an odd chain of reefs suggests there are mysteries about the development and durability of coral colonies yet to be uncovered.

Associate Professor of Earth, Ocean and Atmospheric Science Amy Baco-Taylor, in collaboration with a team from Texas A&M University, observed these reefs during an autonomous underwater vehicle survey through the seamounts of the Northwestern Hawaiian Islands.

‘Weedy’ fish species to take over our future oceans

University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small ‘weedy’ species dominating marine environments.

It’s time to get serious about CO2

It’s time to get serious about CO2, for the ocean’s sake and for ours.

Message from Mr Kosi Latu, Director General of the Secretariat of the Pacific Regional Environment Programme (SPREP), this World Environment Day

“As we commemorate World Environment Day, connecting with nature, we focus our periscope on our Ocean. We must remember that our actions affect the ocean, even if we don’t live by the beach or eat fish. Reducing our carbon dioxide emissions will support ocean health – and the alternative is grim.

The carbon conversation is nothing new. Whether you believe in climate change or not, we can all agree that when we drive cars, or buy new things in shiny plastic packaging, or go for a run, we produce CO2.

Minimising and addressing ocean acidification is of the objectives under Sustainable Development Goal 14, Life Under Water. The global community has come together at the first United Nations Ocean Conference in New York this week (5 – 9 June, 2017) to look for solutions.

If we just talk about the “extra” CO2 that we humans generate with our industrial processes and intensive agriculture, about a third of that extra CO2 ends up in the ocean. When it enters the seawater dissolves making it more acidic.

The pH, or acidity level of the ocean has changed, by about 30% since before the Industrial era, a rate of change faster than anything we have seen in the past 300 million years – a process known as ocean acidification. This process affects a wide variety of marine animals including some of the seafood we eat. New research shows that the protein content of edible whelks, (edible sea snails) drops in conditions similar to those expected with climate change.

Pingree reintroduces bipartisan bill to study impact of ocean acidification on coastal communities

Maine businesses and organizations have come out in support of the legislation.

Congresswoman Chellie Pingree has reintroduced a bill that would require federal officials to work with coastal communities in Maine and around the country to address the impacts of ocean acidification. The bill, H.R. 2719, has bipartisan support in Congress.

“Climate change and warming temperatures aren’t the only effects of carbon emissions that we have to worry about. Ocean acidification is already having an impact on valuable Maine fisheries,” Pingree said. “It’s time we start paying more attention and getting the information we need to understand the potential impacts on our coastal communities.”

Ocean acidification is a product of increased carbon dioxide (C02) in the atmosphere.  Much of the C02 released into the atmosphere as greenhouse gas pollution gets absorbed by oceans, where it makes the water more acidic.  This makes it harder for clams, mussels and oysters to fully form their shells.  The impact on lobsters is less clear, but there is serious concern that acidification coupled with warming waters could have a significant impact on lobster populations.
