Measuring coral calcification under ocean acidification: methodological considerations for the 45Ca-uptake and total alkalinity anomaly technique

As the oceans become less alkaline due to rising CO2 levels, deleterious consequences are expected for calcifying corals. Predicting how coral calcification will be affected by on-going ocean acidification (OA) requires an accurate assessment...Show More Summary

Exposure history determines the response of the orange cup coral (Balanophyllia elegans) to ocean acidification

Humans are drastically changing the planet by burning fossil fuels that release CO2 into the atmosphere, which comes into equilibrium with the ocean and lowers the pH — this phenomenon is known as ocean acidification. As a result, there is a pressing need to understand how species respond to these changes in the ocean. Researchers […]

Teachers tackle ocean acidification with Olympic Coast National Marine Sanctuary

Ocean acidification can be a daunting topic to cover in the classroom, but for Washington state’s coastal communities, the issue is often personal. In 2005, billions of oysters died along the Northwest coast, and NOAA scientist Richard Feely and other North American scientists have linked this and other shellfish die-offs deaths to falling ocean pH. […]

Future of the sea: ocean acidification

This report summarises evidence of the changes to and drivers of ocean acidification. It explores the current and future impacts of acidification on: marine life and environmental conservation the UK fisheries and aquaculture industries future research needs It was commissioned as part of the Foresight Future of the sea project. Birchenough S., Williamson P. & Turley C., […]

Coral reef fish are more resilient than we thought, study finds

At a time when the Great Barrier Reef and other coral reefs are facing unprecedented destruction, researchers in Australia have found a small ray of hope for the fish that make the reefs their home. Fish are more resilient to the effects of ocean acidification than scientists had previously thought, according to research published Thursday […]

New research delivers hope for reef fish living in a high CO2 world

New research examining the possible impacts of ocean acidification provides fresh hope for the survival of reef fish   Just as when a camera lens comes into focus, the latest research published today sharpens understanding of the implications of ocean acidification on reef fish behaviour, yielding promising results for their current and near-future survival. Chemical […]

Diel CO2 cycles reduce severity of behavioural abnormalities in coral reef fish under ocean acidification

Elevated CO2 levels associated with ocean acidification (OA) have been shown to alter behavioural responses in coral reef fishes. However, all studies to date have used stable pCO2 treatments, not considering the substantial diel pCO2 variation that occurs in shallow reef habitats. Show More Summary

Modern planktic foraminifers in the high-latitude ocean

Highlights We review the knowledge on modern high-latitude planktic foraminifers. Subpolar species currently invade higher latitudes. Climate change affects phenology, seawater pH, and carbon turnover. Modern planktic foraminifers are briefly discussed for their paleoceanographic significance. Show More Summary

Ocean acidification experiments in large-scale mesocosms reveal similar dynamics of dissolved organic matter production and biotransformation

Dissolved organic matter (DOM) represents a major reservoir of carbon in the oceans. Environmental stressors such as ocean acidification (OA) potentially affect DOM production and degradation processes, e.g., phytoplankton exudation or microbial uptake and biotransformation of molecules.

Changes in the partial pressure of carbon dioxide in the Mauritanian–Cap Vert upwelling region between 2005 and 2012

Coastal upwellings along the eastern margins of major ocean basins represent regions of large ecological and economic importance due to the high biological productivity. The role of these regions for the global carbon cycle makes them essential in addressing climate change. The physical forcing of upwelling processes that favor production in these areas are already […]

Support Sea Stories

I firmly believe that good science must always be accompanied with good storytelling. Now more than ever, we must connect those around us to the work we are doing both intellectually (in a way they understand) and emotionally. What better way to do this than in a children’s story book? One of my personal heroes […]

L’eau de la Méditerranée bat des records de chaleur et d’acidité: comment agir? (in French)

En moins de 10 ans, les chercheurs de l’Observatoire de Villefranche-sur-mer ont mesuré des changements extrêmement rapides dus à l’émission de CO2 : une hausse forte et rapide de la température de surface et de l’acidité qui menacent les organismes marins. Et ils soulignent l’urgence d’agir. Port de la darse de Villefranche-sur-mer. Il est un peu […]

Réchauffement climatique : l’impact sur la Méditerranée (video; in French)

    Une fois par semaine, des scientifiques du laboratoire d’Océanographie de Villefranche-sur-mer, embarquent à bord du Venelle et mettent le cap sur l’entrée de la rade. Leur mission : mesurer la température de l’eau, le pH… Et les résultats sont alarmants:  En 10 ans, la température de l’eau en surface a augmenté de 0,7° […]

Can eelgrass save our oysters from ocean acidification? (audio)

alifornia researchers want to find out just how much the oft-maligned underwater plant known as eelgrass can help buffer the impact of ocean acidification on sensitive aquatic species. A group from the University of California Davis and UC Santa Cruz was in Orange County’s Upper Newport Bay this week to deploy water chemistry sensors in […]

Can local eelgrass help fight global ocean acidification? Newport Bay research may help provide answers

Eelgrass growing in Newport Beach waters may help prove its importance in maintaining healthy water chemistry by keeping acidity down and making the water more hospitable to ecologically and economically valuable organisms. On the idea...Show More Summary

Redox reactions and weak buffering capacity lead to acidification in the Chesapeake Bay

The combined effects of anthropogenic and biological CO2 inputs may lead to more rapid acidification in coastal waters compared to the open ocean. It is less clear, however, how redox reactions would contribute to acidification. Here we report estuarine acidification dynamics based on oxygen, hydrogen sulfide (H2S), pH, dissolved inorganic carbon and total alkalinity data […]
