New report shows extensive ocean acidification
A new study of ocean acidification in the Arctic shows that the oceans are more acidic. The last 200 years the average acidity of the surface increased by about 30 percent worldwide, and the Arctic is particularly vulnerable. An international research team has been engaged by Arctic Monitoring and Assessment Programme (AMAP) – a working [...]
Arctic Ocean ‘acidifying rapidly’
The Arctic seas are being made rapidly more acidic by carbon-dioxide emissions, according to a new report. Scientists from the Arctic Monitoring and Assessment Programme (AMAP) monitored widespread changes in ocean chemistry in the region. They say even if CO2 emissions stopped now, it would take tens of thousands of years for Arctic Ocean chemistry [...]
Ny rapport viser omfattende havforsuring (in Norwegian)
En ny utredning om havforsuring i Arktis presenteres 6. mai 2013 under konferansen AMAP International Conference on Arctic Ocean Acidification i Bergen. Utredningen viser at verdenshavene blir surere. De siste 200 årene har gjennomsnittlig surhet i havoverflaten økt med omkring 30 prosent på verdensbasis, og Arktis er spesielt utsatt. Havet i Arktis absorberer CO2. Dette [...]
Outreach, the academic formula, and the need for critical examination
COMPASS recently published a commentary in PLOS Biology on the journey from science outreach to meaningful engagement. This post attempts to synthesize a series of reactions, reflections, and personal experiences that followed with the hope to expand the conversation. Show More Summary

Long-term trends in calcifying plankton and pH in the North Sea
Relationships between six calcifying plankton groups and pH are explored in a highly biologically productive and data-rich area of the central North Sea using time-series datasets. The long-term trends show that abundances of foraminiferans,...Show More Summary
Dynamics of seawater carbonate chemistry, production, and calcification of a coral reef flat, Central Great Barrier Reef
Ocean acidification is projected to shift coral reefs from a state of net accretion to one of net dissolution this century. Presently, our ability to predict global-scale changes to coral reef calcification is limited by insufficient data relating seawater carbonate chemistry parameters to in situ rates of reef calcification. Here, we investigate natural trends in [...]
Shipping contributes to ocean acidification
The potential effect on surface water pH of emissions of SOX and NOX from global ship routes is assessed. The results indicate that regional pH reductions of the same order of magnitude as the CO2-driven acidification can occur in heavily trafficked waters. These findings have important consequences for ocean chemistry, since the sulfuric and nitric [...]
IOOS: Ocean acidification (video)
Since the start of the industrial revolution, the ocean has silently absorbed roughly 30% of the carbon dioxide that people generate through industry and agriculture. Now ocean chemistry of the seawater is rapidly changing in a process known as ocean acidification. These changes in seawater chemistry affect animal growth, survival and behavior, and they are depleting the [...]
Ocean acidification in Washington State: Shallin Busch (video)
Shallin Busch is a research ecologist at NOAA’s Northwest Fisheries Science Center (NWSFC). Her current research focuses on how ocean acidification may impact North Pacific ecosystems. Using the NWFSC ocean acidification experimental system, Dr. Show More Summary
A key experiment to probe the future of our acidifying oceans
In a Swedish fjord, European researchers are conducting an ambitious experiment aimed at better understanding how ocean acidification will affect marine life. Ultimately, these scientists hope to determine which species might win and which might lose in a more acidic ocean. The sea urchin is a doughty animal that can withstand cold and turbulent seas, [...]
Marine fungi may benefit from ocean acidification
Recent studies have discussed the consequences of ocean acidification for bacterial processes and diversity. However, the decomposition of complex substrates in marine environments, a key part of the flow of energy in ecosystems, is largely mediated by marine fungi. Although marine fungi have frequently been reported to prefer low pH levels, this group has been [...]
10 Reasons Why Bone Eating Worms Are F’n Awesome
The deep-sea Osedax bone-devouring worms could easily have been the poster child for Deep-Sea News instead of the Giant Squid. Below is list of 10 reasons why Osedax are the shiznit. The chicas are freaky. All whalebone-eating, female worms have dwarf males, up to 114 in Osedax rubiplumus, fruiting around inside of their body. Show More Summary
Victory! Maryland Becomes First East Coast State to Ban Shark Fin Trade!
Governor Martin O'Malley signs bill into law banning possession, sale, and distribution of shark fins in Maryland
Maryland made history today by becoming the first East Coast state to ban the possession, sale and distribution of shark fins throughout the state. Show More Summary
Delaware Sends Shark Fin Ban to Governor
Less than one week after passing the state Assembly, the Delaware state Senate has signed on to a bill banning the trade of shark fins within the state’s borders.
The states spanning the entire West Coast, plus Hawaii and Illinois, already have shark fin bans in place. Show More Summary
Respiration of Mediterranean cold-water corals is not affected by ocean acidification as projected for the end of the century
The rise of CO2 has been identified as a major threat to life in the ocean. About one-third of the anthropogenic CO2 produced in the last 200 yr has been taken up by the ocean, leading to ocean acidification. Surface seawater pH is projected to decrease by about 0.4 unit between the pre-industrial revolution and [...]
End of the century pCO2 levels do not impact calcification in Mediterranean cold-water corals
Ocean acidification caused by anthropogenic uptake of CO2 is perceived to be a major threat to calcifying organisms. Cold-water corals were thought to be strongly affected by a decrease in ocean pH due to their abundance in deep and cold waters which, in contrast to tropical coral reef waters, will soon become corrosive to calcium [...]
Une étude paneuropéenne majeure sur l’acidification des océans (in French)
Plus de 160 chercheurs de 10 pays européens ont uni leurs forces dans le cadre du tout premier projet international se concentrant sur l’acidification des océans et ses conséquences. D’après les partenaires du projet EPOCA («European Project on Ocean Acidification»), la recherche marine était un domaine relativement nouveau lorsqu’ils ont commencé le projet il y [...]
